Question

what do you understand
1) antimatter
2) black hole
3) supernova
4) time travel
5) parallel world

copy paste strictly prohibited

Answer 1

Answer:

1) antimatter: Antimatter is the opposite of normal matter. More specifically, the sub-atomic particles of antimatter have properties opposite those of normal matter. The electrical charge of those particles is reversed.

2) black hole: A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.

3) supernova: Supernovae are more energetic than novae. In Latin, nova means "new", referring astronomically to what appears to be a temporary new bright star. Adding the prefix "super-" distinguishes supernovae from ordinary novae, which are far less luminous. The word supernova was coined by Walter Baade and Fritz Zwicky in 1929.

4)time travel :Time travel is the concept of movement between certain points in time, analogous to movement between different points in space by an object or a person, typically with the use of a hypothetical device known as a time machine. Time travel is a widely recognized concept in philosophy and fiction. The idea of a time machine was popularized by H. G. Wells's 1895 novel The Time Machine.

5)parallel word: A reality or world that exists simultaneously with ours, but independent of it

Answer 2

Hey mate

Here is your answer

1. Antimatter refers to sub-atomic particles that have properties opposite normal sub-atomic particles.
2. A black hole is a place in space where gravity pulls so much that even light can not get out.
3. A supernova is a large explosion that takes place at the end of a star's life cycle.
4. Time travel is a widely recognized concept in philosophy and fiction.
5. A reality or world that exists simultaneously with ours, but independent of it.

Thankyou

Good night
