We know "dark matter is present because it affects the world in ways I do not know of.
It means that no matter how dark the present is still there is something bright in the future.
No, this is not possible. Dark matter is a form of matter that is undetectable by human senses, because it does not interact with any of the four fundamental forces that affect the visible universe (electromagnetism, strong nuclear force, weak nuclear force, and gravity). Therefore, it is impossible for dark matter to become normal matter as observed at a human sensory level.
Ah, isn't that a lovely question! The opposite of dark matter would be what we call regular or visible matter, like the trees, mountains, and fluffy little clouds we see every day. Just like how light and shadow come together to create a beautiful landscape painting, dark matter and regular matter are essential parts of the vast canvas of our universe.
Anti-dark matter, also known as mirror matter, is a theoretical concept that proposes the existence of a mirror universe with particles that are the mirror image of ordinary matter particles. This idea is based on the theory of symmetry in physics. If anti-dark matter exists, it could help explain the mysterious dark matter that makes up a significant portion of the universe's mass. Studying anti-dark matter could provide insights into the nature of dark matter and help us better understand the fundamental forces and particles in the universe. However, there is currently no direct evidence for the existence of anti-dark matter, and further research is needed to explore its potential implications for our understanding of the universe.
Dark energy is believed to make up about 73% of the mass of the Universe; dar matter about 23%; and normal matter - the kind we know most about - about 4%. In the case of normal matter, most of it is still in the form of hydrogen.
At present we do not know. It might be almost motionless, it might have a high velocity, it might have a velocity near that of light. These three hypotheses of the nature of dark are called (respectively); cold dark matter, warm dark matter, and hot dark matter.
No, Einstein did not know about dark matter during his lifetime. The concept of dark matter was not proposed until the 1930s, after Einstein's major contributions to the field of physics.
Standard physics and chemistry are based on the energy and matter that we know. We do not know much about dark energy or dark matter, but only that it may exist.
It is currently unknown as scientists do not even know what dark matter is.
The only similarity we know of is that they all seem to interact with gravity. Aside from that, scientists do not know what dark matter is.
Astronomers can infer the mass of a galaxy from the rate at which it rotates. The visible, glowing matter in galaxies (i.e., the stars) do not account for the amount of matter which we know must be there, hence we conclude that there is some additional matter which we do not see because it does not glow, or in other words is dark. Beyond that, we don't know very much about dark matter.
We don't really know very much about dark matter, so most of its properties (like how it feels) are not known.
Dark matter is matter that does not interact via the electromagnetic force. We don't really know what dark matter is, exactly; there are several possibilities. We know that it interacts via gravity, meaning it has mass. It may, or may not, or SOME of it may, interact via the weak force as well.
well because it occupies moat of the space in the universe
If all thing things pass through a worm hole. We have dark matter all over. How can it not past through a singletary. If you take all that we know about time. We always had a missing pieces. Ok, no more bull I believe that Dark Matter is Time . Matter flows into the center of a black hole and we know that nothing can escape. But we have too know that Dark Matter has too also have to go through the black hole. What if we look at Black Matter as a part /or time it self. We can't say that we know what Dark Matter is. We can't say what Time is. What if they were both the same. We know that they can not be Separated. I believe one day that it's from a Black Hole that we will see the Time distortion between Dark Matter and a Gravity Well. Remember Dark Matter is Matter. We can't see it right now. Just like Time. But who's to say there not the same.
It is not currently know what exactly dark matter is made of. However, it is suspected to be some sort of particle.
We do not know as we have not found any dark matter to examine. The only way we detect it and know it exists is due to its gravitational attraction of the ordinary matter we can see. One speculation when neutrinos were discovered to have tiny nonzero masses was that dark matter might be neutrinos. Another speculation is that dark matter is only ordinary matter, but its in another separate universe in a shared higher dimensional spacetime. Nobody knows.
