Question

how many stars are there in universe and what is the dark matter beyond the stars ?​

Answer 1

Answer:

(i) There are approximately 200 billion trillion stars in the universe.

(ii) The rest of the universe (leaving observable universe) appears to be made of a mysterious, invisible substance called dark matter (25 percent) and a force that repels gravity known as dark energy (70 percent)

Dark matter is composed of particles that do not absorb, reflect, or emit light, so they cannot be detected by observing electromagnetic radiation. Dark matter is material that cannot be seen directly. We know that dark matter exists because of the effect it has on objects that we can observe directly.
