Question

1.What is dark energy?
2.What is dark matter?
3. Do neutrinos have mass?
PLEASE ANSWER THESE QUESTIONS HONESTLIY.

Answer 1

Explanation:

short, dark matter slows down the expansion of the universe, while dark energy speeds it up. Dark matter works like an attractive force — a kind of cosmic cement that holds our universe together.

Answer 2

Explanation:

Dark energy the name given to the mysterious force that's causing the rate of expansion of our universe to accelerate over time, rather than to slow down. That's contrary to what one might expect from a universe that began in a Big Bang. ... The universe is seen as expanding faster today than billions of years ago.

2.What is dark matter?

Dark matter is a hypothetical form of matter thought to account for approximately 85% of the matter in the universe. ... Because dark matter has not yet been observed directly, if it exists, it must barely interact with ordinary baryonic matter and radiation, except through gravity.

3. Do neutrinos have mass?

Neutrinos, some of nature's weirdest fundamental particles, are nearly massless—emphasis on nearly. They were predicted to be completely massless, but experiments roughly 20 years ago found they surprisingly do have some mass.
