A group of scientists suggests that the formation of new stars and galaxies may occur by the gravitational pull of nearby galaxies.
The idea here is that one galaxy can push out into the universe and then form stars, but other galaxies have a stronger pull and can pull off the process by themselves. It’s a fairly common idea that the universe is pulling the galaxies together to form it, so it makes sense that there’s a little bit of a gravity tug-of-war going on.
I’m not sure if this is true, but it’s an idea that I’ve heard a lot of times. I think the reason is that the universe doesn’t actually take any shortcuts when it comes to structure and gravity. It’s an extremely self-regulating system, so there are actually lots of places where the universe has to make more room for itself to form the universe as we know it.
There are a lot of theories out there that suggest when we are nearby to other large galaxies, or more specifically when we are near the center of a galaxy (or if we are near a supermassive black hole, we can actually form from the gravitational pull of those), its because we’re all just spinning around, and that the universe is pulling on us. However, this idea is a little more complicated.
Actually, most of these theories are just weird variations on “the universe is pulling or pushing on a galaxy” and “gravity is pulling on us”. The truth is that most of these theories are wrong and it’s just a theory. In fact, there are some very real examples of galaxies that actually formed from the gravitational pull of another galaxy. This happens all the time and it takes place in the universe at our very doorstep. As such, it’s not really a theory.
The other theory is that the universe is actually pushing on our galaxy. Like gravity isn’t what pulls us to the galaxy but instead the universe is pulling us there. This is a neat theory although I think it only applies to objects that are moving along the cosmic web.
It really doesn’t matter if you think the universe is pushing against us or if you think gravity is the cause. Our galaxy is just one of many, and if we consider all of them to be galaxies, then it is a very real place where galaxies form.
This theory of galactic gravitational waves explains why we have a lot of stars that are moving away from each other. It is not an explanation for why we have so many galaxies, it is a theory that the universe is pulling us to them. One of the ways that this happens is if your two galaxies are close enough that their gravity is attracting each other, then space can move back and forth from there, creating gravitational waves.
So if you put two galaxies next to each other, the space in between them could move back and forth from there, causing a gravitational wave. This is what the new trailer shows us in action. There are two gravity waves in this image, one large enough to affect the entire universe, and one smaller wave that happens only between the two galaxies.
This is just one theory, but a new study finds that the same phenomenon could occur in the space between galaxies. And this is all according to a paper in the journal Physical Review Letters.
