What Am I Missing?
The Dream: Chronos - To all who chase success lead forth by aspiration I do apologize. It was a long held belief of mine that this mindset alone would carry me to the heights of accomplishment. I however, was wrong. This path has only demonstrated how narrow it may become. One must perish any hope of fulfillment being attained in a short amount of time this way. Disillusioned I’d ask myself, “what am I missing?” so little to say that means so much.

How a Negative Ions Sticker can Protect you Against Phone Radiation
The use of smartphones and other electronic devices has become a constant in our daily lives, but what many people may not realize is that these devices emit radiation. This radiation can have negative effects on our health, such as increased risk of cancer, headaches, and sleep disturbances. In this article, we will discuss the dangers of radiation emitted by electronic devices and how a negative ions sticker can help reduce the harmful effects. Negative ions are known to neutralize the positive ions that are emitted by electronic devices, creating a more balanced environment and reducing the negative effects of radiation on our health. By understanding the benefits of negative ion stickers and how they can help reduce radiation emitted by our devices, we can take a proactive approach to protecting our health and well-being.

How do Black Holes behave?
Black holes are some of the most mysterious and fascinating objects in the universe. They are formed when massive stars die and their cores collapse in on themselves. The intense gravity of a black hole is so strong that nothing, not even light, can escape it once it crosses the event horizon. This makes black holes invisible to telescopes and makes them difficult to study. Despite this, scientists have been able to infer the properties and behavior of black holes by observing their effects on nearby matter and radiation.

As I Watch Elon Musk Slowly Sink Into Self-Destruction, he's taking Humanity with him...
Even as I write this, Elon Musk sinks evermore into a mire of BS and narcissism driven by the self-reflective and reflexive magic 8 ball that is the social media of Twitter. Exactly what I warned him about in April of 2022. Both of us have other matters that can take our time and attention away from what should be our primary focus - the survival of Humanity. Twitter has absolutely nothing to do with that, despite what Elon may insist - which confirms my plunging opinion of him - and what his minions may proclaim - only solidifying my opinion of their status of mindless morons.

DARK ENERGY
DARK MATTER Dark matter is a hypothetical form of matter that is thought to make up approximately 85% of the matter in the universe. Despite its name, dark matter does not emit, absorb, or reflect any electromagnetic radiation, making it invisible to telescopes. Instead, its presence is inferred through its gravitational effects on visible matter. One of the first indications of the existence of dark matter came from observations of galaxy rotation curves. In the 1930s, Swiss astronomer Fritz Zwicky observed that the outer regions of galaxy clusters were rotating much faster than would be expected if the visible matter in the galaxies was providing all of the gravitational force. Similar observations have been made in individual galaxies, including our own Milky Way. The idea of dark matter was further supported by the observation of gravitational lensing, which occurs when the gravity of a massive object bends and amplifies the light from a more distant object behind it. The amount of lensing observed is much greater than would be expected if the lensing object was made up of only visible matter. Another piece of evidence for dark matter comes from the study of the cosmic microwave background radiation, the afterglow of the Big Bang. The temperature fluctuations in this radiation are thought to be the seeds that eventually grew into the large-scale structure of the universe we see today. Computer simulations of the universe, which include the effects of dark matter, have been able to reproduce the observed temperature fluctuations, while simulations without dark matter do not. The most widely accepted theory for the nature of dark matter is that it is composed of weakly interacting massive particles (WIMPs). These particles would not interact with electromagnetic radiation, but would interact through the weak nuclear force and gravity. WIMPs are a popular candidate for dark matter because they would naturally arise in many theories beyond the standard model of particle physics. There are several ongoing experimental efforts to detect WIMPs directly. These include experiments that look for the tiny amounts of energy that a WIMP would transfer to a detector when it collides with a nucleus, as well as experiments that look for the gamma rays that would be produced when two WIMPs annihilate each other. So far, no direct detection of WIMPs has been made, but many experiments are currently under way and will continue to search for WIMPs in the future. Another possible explanation for dark matter is that it is composed of much lighter particles, such as axions or sterile neutrinos. These particles would not be expected to be detected directly, but their effects on the cosmic microwave background radiation could be observed. In summary, dark matter is a hypothetical form of matter that is thought to make up most of the matter in the universe. Its existence is inferred through its gravitational effects on visible matter, such as galaxy rotation curves and gravitational lensing. The leading theory for the nature of dark matter is that it is composed of weakly interacting massive particles (WIMPs), which are being searched for in ongoing experiments. Other possibilities include lighter particles such as axions or sterile neutrinos. Despite many efforts to detect dark matter, it has not yet been directly observed. DARK ENERGY Dark energy is a mysterious and unexplained form of energy that is thought to make up approximately 68% of the universe's total energy density. It is believed to be responsible for the acceleration of the expansion of the universe, as it acts as a repulsive force that counteracts the force of gravity. One of the main pieces of evidence for the existence of dark energy is the observation of Type Ia supernovae, which are extremely bright explosions that occur when a white dwarf star accretes matter from a companion star. Scientists have observed that these supernovae are dimmer than expected, which suggests that the expansion of the universe is accelerating. The current leading theory for dark energy is the cosmological constant, first proposed by Einstein. This theory suggests that dark energy is a form of energy that is evenly distributed throughout the universe and is inherent to the fabric of space-time itself. Another theory for dark energy is the concept of "quintessence," which suggests that dark energy is a dynamic field that changes over time. The study of dark energy is still in its early stages and scientists are actively working to understand its properties and behavior. The Planck satellite and Euclid space telescope are currently collecting data to help scientists better understand dark energy and its role in the universe.

The Mysterious and Fascinating Possibilities of the Multiverse
The idea of the multiverse is an idea that has been around for centuries, and it is one that continues to fascinate and captivate the imagination of many. In simple terms, the multiverse is the idea that there are multiple universes that exist in their own separate realms, including the universe we live in, and the infinite possibilities that come with that. It’s an intriguing concept, but it’s also one that can divide opinion and generate heated debate.

A New Class of Dead Star?
Some neutron star basics Neutron stars have a radius on the order of 10 kilometres with a mass of about 1.4 solar masses. They result from the supernova explosion of a massive star, combined with gravitational collapse. The huge gravitational collapse the core past white dwarf star density (~10⁶ g/cm³, or 1 tonne per cubic centimetre) to that of atomic nuclei (~3×10⁸g/cm³), resulting in a diameter of about 20 km.
