Hello everyone. I am a teenager and I just started being interested in space and cosmology. so I'm sorry if my theory is unrealistic or doesn't make sense. But i just thought that it was worthy of discussion and review of others. So, here it is:

Spacetime never ends. It can't end. But what defines "things" such as energy and matter, will start becoming very little amounts near the edge, fading away just like the earth's atmosphere doesnt have a set border. After the fade goes long enough that there is no matter or energy left, it's just empty space, time, gravity (which is insignificant at atomic scales), and fields. This reaches out forever. in an empty void.
