Newly discovered “ DARK MATTER “ in astronomy !
Have any of you know or heard about the newly discovered Dark Matter?
we are not sure about the existence of dark matter , we are just as uncertain about its identity and structure. First, it is dark, meaning that it is not the shape of a star or a planet that we can see. Studies have shown that. There are so many gaps that 25% is needed to form the universe. Second, it is not like any dark cloud of normal matter.
There is no such thing as an atom — Baryons . The only reason we know this is because we can detect baryonic clouds that detect the absorption of radioactive radiation passing through them. Thirdly, dark matter is not an antimatter because dark matter is the kind of substance that we don’t really know what kind of substance it is and so far this is the best definition of it! We don’t know anything about its origin at all, we don’t know how or what it is made of.
One strange thing is this dark matter. It probably has a kind of animosity with light, because forgetting dark matter has nothing to do with light. Neither does it absorb light, nor does it reflect. As a result, it cannot be shown. Not only light, it treats any of our electromagnetic waves the same way.
What is this dark matter made of ?
What Dark Matter is made of is not yet known, but it has been confirmed that it has nothing in common with anything we know. Electrons are not protons or neutrons, dark matter is made of something we have not yet discovered.
However, quantum physics speaks of a kind of atomic particle called “axion”, which has some similarities with the properties of dark matter. Maybe made with Dark Matter Axion, maybe not again. Science is still looking for answers.
According to a hypothesis, dark matter is made up of WIMP = Weakly Interacting Massive Particle, which is characterized by the fact that it interacts with matter so weakly that any massive dark matter can pass through us effortlessly.
What kind of energy is Dark Energy?
It is not yet possible to determine what kind of energy this dark energy is. However, several theories have been put forward. According to one theory, dark energy is a feature of zero or empty space that pushes two objects to create more empty space between them. Just the opposite of the gravitational ball.
About 68% of our universe is made up of this black magic. As the universe expands, the more space there is, the more dark energy there is, and the more energy it is pushing galaxies farther away. As a result, the speed of expansion is increasing.
According to another idea, a particle in space is constantly created like a bubble from zero and then merges like a bubble. Dark energy is created from this mysterious particle. However, all these ideas are limited to ideas only. Scientists are trying their best to unravel the mystery.
Dark Energy and Cosmic Horizon
But one thing is going to happen as a result of this pushing action of Dark Energy. As the universe continues to expand, distant planets and stars will eventually move so far away that the light reflected from them cannot be captured even by the most powerful telescope on Earth. As a result, “Cosmic Horizon” will become smaller.
Cosmic horizons are as much space in the universe as we can gather any information from. Stay close no matter the distance- the matter is not allowing Dark Energy to happen so easily!
About 68percent of our universe is made up of this black magic . Well, if Dark Matter is 27 percent of the universe, Dark Energy is 8 percent, then how much of it falls on ordinary matter? 5 percent! We, our earth, the solar system, all the galaxies — all together make up only 5 percent of the universe! The remaining 95 percent is completely unknown to us.
