Curious how they even know which direction would be the center of the universe?

There is technically is no “center” to the universe as by definition, the universe is everything. Some think that if you traveled far enough out in a straight line, you’d eventually end up back where you started. It’s the 4-dimensional equivalent of a 2-dimensional object moving on the surface of a 3-dimensional sphere. No matter what direction the 2-dimensional object travels, it winds up back where it started.
If the Universe is infinite then it has no center.
You can look in any direction and if you could see far enougn you'd see the beginning. The theory is that the universe is a 3 dimensional bubble expanding in a 4th dimensional space. We can't see into that 4th dimension . If we could see far enough in sufficient detail you'd see your own spot but as it was billions of years ago.
