Does infinity naturally occur physically in the universe?

Is there any evidence that shows something goes to infinity in nature? Like there is infinite time, or infinite space in the universe?

If there is no evidence suggesting that, does that mean there may be a finite amount of time or space? What would be the implications of that?

We don't know if there's infinite time or space, because we can't see that far into our universe and we don't live forever. In fact, we think the universe is expanding at an accelerating pace, but what will ultimately happen we don't know! Will it eventually slow down? Will it continue to accelerate out forever? 

Now, outside of spacial and temporal coordinates, there are other ways in which infinity appears in nature. For example, our current theory says that you cannot accelerate an object with mass to the speed of light. This is because as it gets faster, it takes more and more energy to increase its speed- and to the speed of light, infinite energy. 

Of course, infinity also often comes up in math, the language we developed/discovered to explain what we see around us. Infinity pops up frequently when working with the differential equations in quantum mechanics, especially in boundary conditions (like energy in a well, for example). Mimicking the functions we see through Fourier or polynomial series requires infinite sums. Infinity comes up a lot!
