This whole comment comes up as pseudoscience based on myths on big bang. Accordingly we can guess that the link goes to such pseudoscience and is likely self-promotion of a personal brand of erroneous claims. I am increasingly convinced that modern astronomy is a pseudoscience that has been standing still for years, and if it sees something in telescopes, it does not understand anything. Your baseless claim that science — with its literary ,s of experts having worked for centuries — is a pseudoscience falls flat.
It is a fact that the early universe was very dense — and so hot, with lots of kinetic energy to add to the general relativistic description — but if there were any relativistic effects they do not show up in the cosmic background radiation imprint much later. We lack evidence of them and added to that they would have had fleeting influence.

Saul Perlmutter, in his Nobel Prize Lecture, said: The best fit curve was decelerating for about the first seven billion years, and then accelerating for the most recent approximately seven billion years. That is a good question! The Big Bang is the explosion that began our Universe.

Dark matter is really hard to study, because we have no way of seeing it.
So how do we know it exists? We can also see the effects of dark matter simply by looking up at the sky. When astronomers observe distant galaxies, they often appear stretched and oddly shaped. This force is so huge that it physically bends the light around galaxies, distorting their appearance. Scientists have been able to piece together maps of space, indicating where they think dark matter is hiding.
We already know about photons, electrons, quarks and many other particles, but there may be plenty of others waiting to be discovered.
According to one idea, dark energy is a fifth and previously unknown type of fundamental force called quintessence, which fills the universe like a fluid. Many scientists have also pointed out that the known properties of dark energy are consistent with a cosmological constant, a mathematical Band-Aid that Albert Einstein added to his theory of general relativity to make his equations fit with the notion of a static universe.
According to Einstein, the constant would be a repulsive force that counteracts gravity, keeping the universe from collapsing in on itself. Einstein later discarded the idea when astronomical observations revealed that the universe was expanding, calling the cosmological constant his "biggest blunder.
Now that we see the expansion of the universe is accelerating, adding in dark energy as a cosmological constant could neatly explain how space-time is being stretched apart. But that explanation still leaves scientists clueless as to why the strange force exists in the first place. All rights reserved. Unlocking the Mystery Scientists have not yet observed dark matter directly.

Go Further. How could it correctly describe the motion of the bodies in the Solar System, as Einstein's theory is known to do, and still give us the different prediction for the universe that we need?
There are candidate theories, but none are compelling. The thing that is needed to decide between dark energy possibilities - a property of space, a new dynamic fluid, or a new theory of gravity - is more data, better data.
What is dark matter? We are much more certain what dark matter is not than we are what it is. First, it is dark, meaning that it is not in the form of stars and planets that we see. Second, it is not in the form of dark clouds of normal matter, matter made up of particles called baryons. We know this because we would be able to detect baryonic clouds by their absorption of radiation passing through them.
Third, dark matter is not antimatter, because we do not see the unique gamma rays that are produced when antimatter annihilates with matter. Finally, we can rule out large galaxy-sized black holes on the basis of how many gravitational lenses we see. However, at this point, there are still a few dark matter possibilities that are viable. Baryonic matter could still make up the dark matter if it were all tied up in brown dwarfs or in small, dense chunks of heavy elements. But the most common view is that dark matter is not baryonic at all, but that it is made up of other, more exotic particles like axions or WIMPS Weakly Interacting Massive Particles.
Dark Energy, Dark Matter In the early s, one thing was fairly certain about the expansion of the universe. What Is Dark Energy? Universe Dark Energy-1 Expanding Universe. This diagram reveals changes in the rate of expansion since the universe's birth 15 billion years ago. The more shallow the curve, the faster the rate of expansion. The curve changes noticeably about 7. Astronomers theorize that the faster expansion rate is due to a mysterious, dark force that is pulling galaxies apart.
