is dark matter really exist? Dark matter is completely invisible. It emits no light or energy and thus cannot be detected by conventional sensors and detectors. The key to its elusive nature must lie in its composition, scientists think.
What can neutrinos interact with? The only ways they interact is through gravity and the weak force, which is, well, weak. This weak force is important only at very short distances, which means tiny neutrinos can skirt through the atoms of massive objects without interacting. Most neutrinos will pass through Earth without interacting at all.
What can interact with dark matter? Unlike normal matter, dark matter does not interact with the electromagnetic force. This means it does not absorb, reflect or emit light, making it extremely hard to spot. In fact, researchers have been able to infer the existence of dark matter only from the gravitational effect it seems to have on visible matter.
What is dark matter and what evidence for it exists? Answer: Dark matter is the name scientists have given to the particles which we believe exist in the universe, but which we cannot directly see! Dark matter was initially called “missing matter” because astronomers could not find it by observing the universe in any part of the electromagnetic spectrum.

when will mass extinction happen?
In mass extinctions, at least three-quarters of all species cease to exist within about 3 million years.

Over the next few decades alone, at least 1 million species are at risk of being wiped out.
