there is an edge we can see but it’s not proved that it’s the actual edge of our whole universe. We can only see so far because of how light travels. If we were in a different place in our universe then we could see a different edge. - Lorelei

By looking at the oldest stars, measuring the rate of which they expand going all the way back to the Big Bang. - sophia

Yes, we determined this with the “Red Shift”. As objects move away from us, they become more red. This indicates that the universe is still expanding -Sidney

Even though the universe is expanding and the planets are moving away from the center, there are more planets being born at the same time. Some of those newborn planets happen to be born in the center as well, making it not empty. - Christian

Yes, redshift. All the objects moving away from us have light that stretches out/expands more red. The universe used to be much smaller than it is now. - Sophia

We can prove there’s an “edge” to the universe but we can’t actually see it. Light only travels a certain distance in a certain amount of time so if there’s galaxy’s moving further away as fast or faster than the speed of light then we won’t actually be able to see them (dark matter). This means that we can see an edge but there may be a further edge than we can actually see-sidney

theres still planets being made which makes the canter always filling/michael

By red shift, its moving galaxy's away from each other.-Delilah
