What should I do?
1. Have aliens ever visited earth?
2. Can gravity form waves?
3. Galaxies look stationary, so why do scientists say that they rotate?
4. How bright is a laser beam when viewed from the side?
5. How can you tell a black hole made out of antimatter from a black hole made out of matter?
Answers
Answer:
1 some say that yes they have visited and it might be true b'coz we are not only one living in the entire universe and multiverse .
2. well not sure about that
3. they have observed them for years and came to a conclusion
4 well may be not visible

hey mate take care of ur eyes if u see mobile for such long time u may have chance to get eye problems

Answer:
1. FOR MYSELF NO
2. Yes, gravity can forms waves
3. It's because galaxies are unimaginably huge. An object traveling at high speed across a very long distance appears to be moving slowly when viewed from far away.
4.Any light beam viewed from the side has zero brightness. Only light that reaches the eye, camera, or other sensor, can have any brightness to it, so a beam (especially in a vacuum) is invisible from the side.
5.According to our current understanding, there is no way to distinguish an antimatter black hole from a regular-matter black hole. In fact, there is no difference between an antimatter black hole and a regular-matter black hole if they have the same mass, charge, and angular-momentum..
