How will our universe end ?

If enough dark energy is present in the universe, then the expansion of it will continue. However, if there is not enough dark energy, then the forces of gravity will eventually overrule it and bring everything back together again. Some scientists believe that this could be the beginning of the Big Crunch. However, in 2015 it was suggested that the current increases in expansion may be the last gasp of the expanding universe. In tens of billions of years, the contraction will begin, and everything will return to its original form a massive black hole. What happens at this point is unknown, but one possibility is that we are living in another cycle of expansions and contractions. Only those who plan to be around for millions of years will have to worry about this.

If there isn't enough dark energy, the Big Crunch will happen. At that point, everything will return to where it originates and a black hole will be born. It's also possible that this has happened before, and we're living in an expansion cycle again.

The last decade was a time of rich scientific discovery. Researchers across all disciplines made groundbreaking findings that challenged our understanding of the universe. We gained new insights into our own planet and the entire solar system. Let's explore five amazing scientific discoveries from the 2000s.

Number 5: Pluto. Despite its controversial demotion from planet status, the New Horizons spacecraft revealed astonishing features on Pluto. It has moving glaciers, floating ice mountains, and a frozen sea made of solid nitrogen. This unexpected discovery gave us a new understanding of the mysterious dwarf planet.

Number 4: The Higgs boson. After years of research and the construction of the Large Hadron Collider, the Higgs boson, also known as the "god particle," was finally discovered in 2012. This particle explains why objects have mass and completes the standard model of physics.

Number 3: Kepler. With the launch of the Kepler probe in 2009, we gained the ability to study distant stars and discover exoplanets. Over 4,055 exoplanets have been found, including potentially habitable ones. This suggests that our own solar system may be more common than we thought.

Number 2: Changing climates. Throughout Earth's history, the climate has undergone drastic changes. However, the last decade highlighted the role of human behavior in driving climate change. We are witnessing significant shifts in our lifetimes.

These incredible scientific discoveries have reshaped our understanding of the universe and our place in it. With each new finding, we uncover more mysteries waiting to be explored.

A solar eclipse occurs when the moon blocks the sun's rays from reaching the Earth. Even though the sun is much larger than the moon, they appear the same size because of their distance. Astronomers can predict eclipses because of the predictable orbits of the Earth and moon. However, there isn't an eclipse every month because the moon's orbit is usually tilted. During a solar eclipse, the moon casts two types of shadows on Earth. There are four types of solar eclipses: total, partial, annular, and hybrid. Looking directly at the sun during an eclipse can cause permanent eye damage. It is important to use certified eclipse-watching glasses or make a pinhole viewer to safely view the eclipse. Baily's beads and the Diamond Ring are phenomena that occur just before and after totality. Totality is the only time it is safe to remove the eclipse glasses. Animals and plants may exhibit changes in behavior during a total eclipse.

During totality, it is safe to view the eclipse without glasses. Animals and plants may exhibit changes in behavior during a total eclipse.
