I'm not really smart when it comes to physics and outer space. What was the harm in asking?

No harm. Ignore the people who are giving you shit.

Back to fun space facts, have you ever heard of time dilation? If you were to accelerate to an insane speed in order to reach another planet, you would be perceiving time at a slower rate than the rest of us. There is a scifi book where soldiers go across the galaxy, fighta brief war, then return to an earth that has seen centuries pass during their trip.

Space is expanding at an ever increasing speed. At some point, we may not be able to see other galaxies as the space between galaxies is expanding faster than the light can travel to reach us.
