Eli5: How does gravity affect time, dumb it down for me as much as possible

Answer 1

Energy (mass is energy too) is what creates space-time, so when you have a more dense conglomerate of energy there is “more amount”of space-time so it is more difficult to move within it. Far form there where there is not such amount of energy concentrated space-time gets “weaker” so is more easy to “move” within it.

At the same time space-time dictate how energy (mass too) moves in spaces and displace in time.

So it’s a mutual feedback.

In relativity there is a very important equation that relates both by using math variables called tensors. In the equation energy-tensor says how the metric-tensor **is** and the metric-tensor says how the energy-tensor **moves**.

(Note:actually it’s energy-momentum what creates gravity not only energy)
