Everything in our universe has a limit. It may seem obvious, but it is something worth-considering. If everything has a limit, than there’s no such thing has “infinity”. Something without a limit cannot exist, because it is incompatible with our own reality. We know that there’s a limit to how cold something can get: that’s 0 Kelvin degrees, the minimum possible temperature. We know that there’s a limit to how fast something can go: that’s 300 000 000 meters per second, the speed of light. And we know that there’s a limit to how much of the Universe we can see and interact with.
