James Webb Telescope Just Announced First Ever, Real Image Before Big Bang
It discusses various theories about what might have happened before the Big Bang, such as the big bounce, the ekpyrotic scenario, the pre-Big Bang scenario, and the no boundary proposal.
When you launch a $10 Billion telescope to deep space you should be
prepared to have some of your long
Health theories about the universe
challenged scientists knew this but was
still surprised by the James Webb Space
telescope's latest Discovery what
happened before the Big Bang what has
the jwst discovered about the big bang
and how does it affect astronomy as we
know it stay tuned as we dive into the
James Webb Space telescope's discovery
of what happened before the Big Bang
do you know the Big Bang many people do
especially if they're a fan of the
popular TV show with the same name
however the recent findings hit by the
jwst H into what happened before the Big
Bang but first what exactly happened
during the big bang and how did it bring
us here according to this Theory the
universe started as a very hot dense and
Tiny point of matter and energy which
then rapidly expanded and cooled down
this expansion and cooling process
created the conditions for the formation
of assam's stars galaxies and other
structures that we observed today The
Big Bang Theory is supported by several
lines of evidence such as Hubble's Law
this is the observation that distant
galaxies are moving away from us and the
farther they are the faster they recede
this implies that the universe is
expanding and that it was smaller and
denser in the past the rate of expansion
can be used to estimate the age of the
universe which is currently about 13.8
billion years
Cosmic microwave background radiation
CMB
this is the faint glow of radiation that
fills the entire Sky which is a remnant
of the intense heat and light that
filled the early Universe the CMB has a
very uniform temperature of about 2.7
Kelvin with tiny fluctuation that reveal
the density variations in the primordial
plasma the CMP also shows that the
Universe was opaque to light until about
380
000 years after the big bang when assams
formed and allowed light to travel
freely
abundance of primordial elements
this is the observation that the
universe is mostly made of hydrogen and
helium with traces of our other Light
Elements like lithium beryllium and
Boron these elements were produced by
nuclear fusion reactions in the first
few minutes after the big bang when the
temperature intensity were high enough
for nuclei to form the relative amounts
of these elements agree with the
predictions of big bang nucleosynthesis
a theory that describes how matter was
created in the early universe
Galactic Evolution and distribution
this is the observation that Galaxies
have different shapes sizes ages and
compositions depending on their location
and history galaxies are not randomly
distributed in space but form clusters
and super clusters that are connected by
filaments of matter these structures
reflect how matter has clumped together
under Gravity over time forming stars
and galaxies from smaller fluctuations
in density the oldest galaxies are found
near the edge of our observable universe
while younger ones are closer to us
what really happened before the Big Bang
one of the most exciting and difficult
problems in cosmologies what happened
before the Big Bang The Big Bang Theory
outlines How the Universe originated in
an extremely dense and hot State then
expanded and cooled over time it does
not however explain what produced or
preceded this initial state or whether
such a question is even relevant there
are various plausible explanations that
scientists have proposed for what
happened before the Big Bang among them
are
the big bounce
this Theory holds that our universe is
part of a cyclical process in which a
prior Universe collapsed into a
singularity and then bounced back into a
new one this cycle may have been
repeated an endless number of times the
big bounce could be caused by Quantum
processes gravity or other spatial
Dimensions the egg parotic scenario
which proposes that our universe arose
from the Collision Of Two Brains which
are tiny sheets of matter and energy
that reside in a higher dimensional
region the Collision sparked a burst of
inflation a rapid expansion that
smoothed out our universe's initial
circumstances the brains could Clash on
a regular basis resulting in the
creation of numerous universes
the pre-bigbang scenario
this is the theory that our universe
developed from a condition of low energy
and high curvature into a state of high
energy and low curvature this transition
included a period of super inflation
which magnified Quantum fluctuations and
transformed them into seeds for Cosmic
structures the pre-big bank scenario is
based on string theory which is a
framework that unites all natural forces
and particles
the no boundary proposal
this is the theory that our universe has
no boundaries in space or time and that
the Big Bang is a smooth Zone when the
universe's size becomes very small the
no boundary proposal describes the
beginning of the cosmos as a Quantum
fluctuation from nothingness using
quantum physics a wave function that
encodes all potential histories
determines the structure and attributes
of the universe and it's important to
note that these possibilities are not
mutually exclusive and they may be
compatible or complementary in some
cases now finding out how a universe
grew up is one of the biggest science
goals the jwst and with its latest
Discovery it's found the earliest
proto-galaxy cluster ever discovered
just 650 million years after the big
bang in theory the universe has a
hierarchy of how things develop the
universe was almost completely uniform
in the early phases of the hot big bang
all matter and the energy were dispersed
at uniformly throughout space with small
one part in 30 000 perturbations are
overlaid above that uniform background
these oscillations are caused by Cosmic
inflation which preceded and established
the big bang and they exist on all
Cosmic scales tiny intermediers and huge
but because matter and radiation
interact and the universe expands the
smallest scale fluctuations are washed
out the intermediate scales have Peaks
and valleys in weather density
fluctuations are enhanced or suppressed
and the largest at Cosmic scales are
unaffected this information is contained
in the big Bang's residual glow the
cosmic microwave background where it may
still be seen today the overdent regions
then begin to gravitationally develop
while the underdense portions that give
up their matter and energy to their
denser surroundings despite the fact
that gravitation is an infinite range
Force gravitational growth does not
occur evenly throughout the Universe the
important thing to understand is that
gravity like are the messages in the
universe does not reach everywhere
instantly but is instead restricted by
the speed of light if you have an
overdense region in space it can attract
matter that is nearby in a certain
amount of time but matter that is 10
times as distant will take at least 10
times as long probably more given that
the universe is expanding to feel the
gravitational attraction from the same
object the longer it takes for
gravitational pull to begin the larger
and grander the cosmic scale from Star
clusters to galaxies to groups and
clusters of galaxies and Beyond and then
once a large-scale region experiences a
gravitational attraction several events
must occur before a bound structure
forms all of which take time as it moves
away from the gravitational over density
Center the receding matter must slow
down to cause a gravitational collapse
The overdent Zone must reach a critical
mass roughly 68 more than the average
density the large-scale structure must
then stop declining reverse orientation
and begin collapsing and then finally
we'll have a bound object sub-components
that are all part of a larger bound
large-scale structure on a smaller scale
molecular clouds of gas dust atoms and
dark matter are the first formations to
collapse giving rise to the first stars
and star clusters and while the most
common of these are over dense regions
may take 200 to 250 million years to
collapse the earliest ones to do so that
is those with the greatest initial
over-dense conditions may be able to do
so in as little as 50 to 100 million
years now as stars form they emit
radiation and winds which creates
incomprehensibly complex environments
making it difficult to predict any
details about these early structures as
these are early clumps of massage or
more matter into them they also find and
merge with one another forming the
universe's first massive galaxies we've
detected richly evolved galaxies as
early as 320 million years after the big
bang and the limits of what jwst has
observed so far with many of these early
ones being huge rich in heavy elements
and teeming with continuing star
formation jwst was fully expected to
discover these objects there is still
reason to believe that jwst's
capabilities will disclose populations
of totally Immaculate stars as well as
even earlier galaxies on the broader
Cosmic scale however this messy physics
plays a little to no role on the size of
individual galaxies however one must
contend with continuous star production
huge star winds and radiation Stellar
deaths and cataclysms cooling into
infall of gas and other atom-based
matter mergers and nutrition ionization
and the interaction of dark matter with
normal matter but when it comes to the
creation of Galaxy clusters these causes
play a very tiny impact instead the
formation of Galactic groups and Galaxy
clusters is largely determined by three
well-known factors the universe's
expansion is fully determined at all
Cosmic times once we know what's
actually in the universe the magnitude
of the initial over density on the
relevant Cosmic scale which allows us to
compute any such object's rate of
gravitational growth and how that
gravitational increase progresses over
time taking into account the relevant
interplay of multiple Cosmic scales all
of that messed up stuff that happens
inside a Galaxy sometimes it derisively
referred to as a gastrophysics has no
effect on the creation and growth of
Galaxy clusters only gravity matters now
prior to jwst there were a variety of
methods for exposing these galaxies
Masters throughout Cosmic history the
simplest and most straightforward method
was to identify large numbers of
galaxies that existed in the same field
of view at identical redshifts distances
to one another but with a significant
velocity dispersion galaxies within the
cluster moved at speeds of several
hundred or even a few thousand
kilometers per second relative to one
another this method made it simple to
discover nearby Galaxy clusters like
coma and Virgo Galaxy clusters that are
heated such as by the Collision of
fast-moving gas clouds or by intensive
star formation processes release x-rays
throughout the intergalactic medium
within the cluster leaving and
identifying signal if we probe them with
the appropriate wavelengths of light
these x-ray producing clusters are
useful not only for identifying clusters
but also for learning about their masses
gas contents and merger histories and
finally Galaxy clusters have been
revealed by the collective effects of
their Gravity the dominant strong and
weak gravitational lensing a massive
Galaxy cluster will be distinguishable
from a set of unclustered galaxies
because of the lensing features caused
by intracluster matter a mass within the
cluster that exists between the
individual galaxies CL
j1001 plus zero two two zero identified
through his X-ray emissions and whose
light we see 2.7 billion years after the
big bang is a relatively nearby mature
Galaxy cluster that contains 17 distinct
galaxies more than half of which are
Starburst at galaxies forming stars
named massive burst that spans the
entire galaxy galaxy clusters on the
other hand do not begin as mature
objects but rather evolve from an
unformed condition through a
proto-cluster phase to identify the
first such objects we must seek
proto-clusters of galaxies groups that
haven't yet heated up their gas enough
to emit x-rays a survey using the
premier ground-based Observatory such as
Subaru Keck and Gemini revealed two very
distant collections of several galaxies
in the very early Universe one
consisting of 44 galaxies at a redshift
of 5.7 corresponding to an age of 1 1
billion years after the big bang and
another consisting of 12 galaxies and a
redshift of 6.6 corresponding to an age
of 800 million years after the big bang
these Proto clusters were the first
examples of groups of galaxies in a
comparable location in space with their
speeds and masses showing that they are
definitely in the process of becoming
gravitationally linked and may have
already crossed that threshold
scientists fully expected to break this
Cosmic record with the jwst's
unparalleled Cosmic Vision stretching at
the earliest known cluster back to
unimaginable times however it was
expected that this would take some time
because robustly identifying Galaxy
clusters typically necessitates the
coexistence of two sets of observations
first you'll need a wide field
photometric survey that can cover a
large enough area to identify Galaxy
cluster candidates galaxies whose colors
are consistent with them all being very
distant and the same distance there are
three more surveys by the jwst that shed
more light on the Big Bang Jade the jwst
advanced deep extra Galactic survey
glass which examined the deeply lens
Galaxy cluster Abel at 2744 and Sears
the cosmic Evolution early release
science survey have all already
published their findings with Sears
discovering four galaxies in the same
narrow area of sky at the same distance
redshift of 4.9 corresponding to a Proto
cluster just 1.2 billion years after the
big bang however within the glass field
where the effects of a magnifying
foreground Galaxy cluster Abel 2744 are
added the potential for going even
deeper about and as luck would have it
end as far as we can tell it is truly
just luck seven independent Galaxies
have been discovered in the same region
and spectroscopically confirmed to be at
the same redshift 7.8
which corresponds to a Time 650 million
years after the big bang the earliest
proto-cluster of galaxies ever
identified the cluster's name at least
for the time being is quite long
a2744
z7p9od because it was discovered in the
lenting field of Abel 2744 or
a2744 at a redshift of 7.88 which rounds
to 7.9 hence the z7 P9 a part of the
name and its redshift was confirmed
through the detection of doubly ionized
oxygen in each of these seven member
galaxies leaving it unclear whether the
OD part is at for the oxygen detection
or because this Proto cluster represents
an over density the Hubble Space
Telescope previously examined this
galaxy cluster which revealed over 130
times the average number of galaxies
inside a fairly tiny region of space
which includes this newly detected Proto
cluster the most intriguing Galaxy
candidate from the Hubble research
however was designated yd4 and it now
turns out through spectroscopy to be a
redshift of 8.38 indicating that it's
not a member of this Proto cluster but
rather he's still more distant
background object this work not only
reveals the most distant known
proto-cluster or galaxies in the
universe to date but it also emphasizes
how crucial it is to detect and
spectroscopically validate all of the
distant Galaxy candidates that we
anticipate will belong to a single
entity the previous Hubble analysis
predicted a considerably larger more
expensive proto-cluster than exists
there are only roughly 24 times the
number of galaxies in this cluster
rather than the previously anticipated
130. some of the galaxies discovered
were not associated with the Proto
cluster but rather were found elsewhere
along the line of sight furthermore some
candidate galaxies still lack Spectra
emphasizing the importance of observing
them the authors also attempted to
quantify the mass and velocity
dispersion how fast galaxies move
relative to one another within this
Proto cluster and discovered something
remarkable the aggregate mass of the
seven member galaxies is approximately
400 Million Suns which is nearly the
mess the present Milky Way and therefore
places a lower limit on the mass of the
Proto cluster it should have expended to
at least five thousand times their size
by now or to the mass of the modern day
coma cluster and while the estimated
velocity dispersion of 1100 kilometers
per second is highly uncertain it
appears to be remarkably consistent with
known high mass Galaxy clusters now the
jwst again shocks scientists when it
discovered a tiny early Galaxy packing a
big star-forming punch the reason was
that with the Galaxy dating back to
about half a billion years after the big
bang the Galaxy could be a key to
understanding how the cosmic Dark Ages
came to an end the galaxy known as RX
j2129 z95 may be viewed at a redshift of
9.51 that number which refers to the
extent to which the light of the galaxy
has been stretched by the expansion the
universe indicates that we are seeing it
as it existed only 510 million years
after the big bang RX
j2129z95 is extremely faint due to its
great distance however the gravitational
lending effect of a massive foreground
Galaxy cluster called
rxj2129.6 plus 0005 which is located
about 2.5 billion light years from Earth
along the same line of sight boosted its
light the gravity of the 150 trillion
solar mass cluster magnified and split
the light of
rxj2129 z95 into three pictures
jwsts in near spec instrument confirmed
the Galaxy's redshift as well as strong
emission from high hydrogen into oxygen
gas clouds within the
rxj2129z95 and some of this Galaxy's
exceptional features have been revealed
by these emission lines in the Galaxy's
Spectrum however
rxj2129z95 is only
105.6 light years across compared to our
Milky Way galaxies 100
000 light year diameter or even current
dwarf galaxies that span at several
thousand light years and yet despite
having a thousand times less the volume
of the Milky Way
rxj2129z95 has the same rate of star
formation as our galaxy implying that it
is much more intense the jwst is
discovering that such high star
formation rates are a pretty common
feature of galaxies in the early
Universe although
rxj2129z95 is out of the ordinary even
for high redshift galaxies the star
formation rate is similar to other high
redshift galaxies confirmed with near
spec the radius of the Galaxy is at
least three times smaller than those of
other galaxies this means a ton of star
formation is compressed into a very
small volume the fact that all of these
early galaxies are small despite their
tremendous Luminosity supports the
prevalent hypothesis of hierarchical
Galaxy formation which predicts that
smaller galaxies form initially then
merge and develop into larger galaxies
like the Milky Way in addition the team
discovered no indication of an active
supermassive black hole at the center of
rxj2129z95 this could be significant
since this galaxy exists near the end of
the cosmic Dark Ages when radiation
ionized much of the universe's huge
ocean of neutral hydrogen gas one of the
most pressing mysteries in cosmology has
been what caused the end of the Dark
Ages was it radiation from hungrily
developing black holes or enormous
bursts of star formation if RX
j2129z95 is common the lack of an
evident black hole could indicate
radiation from plentiful Bright Young
stars as the primary force in bringing
the Dark Ages to an end however the
amount of ionizing radiation produced by
rxj2129z95 has yet to be Quantified if
there is a substantial population of
similar galaxies then perhaps they play
a key role in the ionizing Photon budget
speculated one astronomer so more
observations of galaxies are similar
redshifts are needed but with the jwst
already confirming a handful of very
high redshift luminous galaxies and much
more likely to follow astronomers will
soon have a large sample to draw from
another shocking discovery made by the
jwst includes six galaxies that are too
massive for their sizes the space
Observatory discovered six huge galaxies
that existed between 500 million and 700
million years after the universe's Big
Bang according to when you study the
Revelation is fundamentally upending
previous beliefs about the birth of
galaxies in a statement research
co-author Joe layer assistant professor
of astronomy and astrophysics at Penn
State University said these objects are
way more massive than anyone expected at
this point in time they're expected to
find only tiny young baby galaxies but
they discovered galaxies as mature as
our own in what was previously thought
to be the dawn of the universe the James
Webb Telescope views the universe in
infrared light which the human eye
cannot see and is capable of detecting
dim light from ancient stars and
galaxies The Observatory can literally
see back in time up to around 13.5
billion years by pair ring into the
distant Universe this discovery that
massive Galaxy formation occurred
extremely early in the history of the
universe challenges what many
astronomers thought was settled science
due to this they have jokingly dubbed
these objects Universe Breakers the
galaxies are so huge that they
contradict 99 of models of early
galaxies in the universe implying that
scientists must reconsider how galaxies
begin and evolve according to current
understanding galaxies originated as
Tiny clouds of stars and dust that
developed throughout time Leia explained
that they looked into the very early
Universe for the first time and they had
no idea what they were going to find but
it turned out that they discovered
something so unexpected that it actually
causes problems for science because it
calls into question the entire picture
of early Galaxy formation when the web
data and the telescope's first
high-resolution images were released a
land his colleagues began analyzing them
the galaxies showed its enormous point
of light the team was astonished to see
them so surprised in fact that they
assumed they had interpreted the data
incorrectly however upon guessing the
data they began modeling and attempting
to figure out what they were because
they were so large and bright the first
assumption was that they had made a
mistake and would just Discover it and
well move on with their lives however
despite their best efforts they have yet
to discover that error now taking a
spectrum photograph of the galaxies
which include splitting light into
multiple wavelengths to identify various
elements and estimate the true distance
of the galaxies is one technique to
understand why the galaxies developed so
swiftly the data from spectroscopy would
provide a more thorough look at the
galaxies and their enormous sights a
spectrum will tell scientists right away
whether or not these things are real it
will explain how big they are and how
far away they are it's also feasible
that the Galaxy is detected with the
jwst's data are something totally else
layers said that this is their first
look back this far so it's critical that
they keep an open mind about what they
see while the data suggests they are
most likely galaxies there is a real
possibility that a few of these objects
are obscured supermassive black holes
regardless though the amount of mass
discovered means that the known massive
stars at this time in our universe is up
to 100 times greater than previously
thought even if the sample is cut in
half this is still a remarkable change
