Is the expansion of the universe really accelerating? Or does it just look like it?

Answer 1

Hello mate here is your answer.

light travels at a constant speed and, on the scale of the universe, a speed that lets us see into the past.When you look at very distant objects in the universe you are seeing them in the past. Say an object appears to be 5 billion light years, then the light we saw it by took five billion years to reach us and the object has moved since then.

Hope it helps you.
