No. There can be other experiencial VRs after this one though, so don't let it get you down. This one began, and it will end. It's spacially and temporally discrete as well.

The current theory is that the universe is infinite but what is the science behind it? How do scientists determine that the universe is infinite?

We can only see a certain distance into the universe, how do we know it doesn't have a limit to it?

No, we don't know if the universe is infinite or finite. It depends on the curvature of space, which we can't measured to the precision required for us to make an educated guess.

Infinity is a mathematical concept that represents a value that is infinitely large or infinitely small, but it is not clear if infinity exists in the physical universe.

There are some things in the universe that appear infinite to us, but they may only be so in terms of our limited ability to observe or measure them. For example, the universe itself may be infinite in size, but we cannot observe the entire universe to know for sure. The same can be said for the concept of time, which may be infinite but is difficult to measure and observe in its entirety.

However, there are also physical limits to what can be infinite in the universe. For example, the speed of light is a fundamental limit in the universe, and there cannot be anything that travels faster than it. The amount of matter and energy in the universe is also limited, and while it may be vast, it is not infinite.

In summary, while infinity is a mathematical concept, it is not clear if it exists in the physical universe. There are some things in the universe that may appear infinite, but they may only be so in terms of our limited ability to observe or measure them. There are also physical limits to what can be infinite in the universe.

It's got to do with the overall geometry of spacetime. We've known for a hundred years that spacetime can be locally flat or locally curved. Is the overall geometry of the universe flat or curved? If it's flat, then EITHER the universe is infinite or it's surrounded by some kind of boundary, which doesn't really make sense. So we measure the overall curvature of the universe by looking at the cosmic microwave background and doing trigonometry. Basically if the universe is overall flat, then the largest triangle in the universe should have internal angles that add up to 180°. So we measure that. And we find that yes, the largest triangles in the universe have internal angles that add up to 180° to within a VERY VERY small margin of error. That leaves the door open to the universe being finite (overall positive curvature), but it's extremely unlikely. It's much more likely that the universe is infinite and just keeps going forever in all directions.

How can it be infinite when the lifespan of the universe is finite?

The universe had a beginning and has been expanding ever since the beginning ,so how is it possible that space goes on forever

https://reducing-suffering.org/believe-infinity/

>Is infinity real or just a fiction of our minds? I briefly review a few arguments for and against the existence of infinity from physics and philosophy, and I conclude that neither side is obviously right. A further question is whether we should prudentially believe in infinity because if it does exist, everything we do matters vastly more. Within a given ontological framework this argument is sound, but different ontological frameworks (e.g., ultrafinitism vs. transfinitism) are not directly comparable. I personally hope infinity does not exist so that the universe contains only finitely much suffering, but unfortunately I think it's reasonably likely that the universe is literally infinite. There remain numerous puzzles in how we approach the ontology and ethics of infinity, many of which may be best left to the future to sort out.

What theory?
Big Bang Theory says that the universe is about 13.7 billions years old, not that it is infinitely old, and it is based on observing redshift and cosmic backround microwave radiation.

The concept of infinity in the context of the universe does not necessarily refer to its duration or lifespan, but rather to its spatial extent. It is possible for the universe to be both finite in age and infinite in size.

The idea that the universe might be infinite in size is based on observations that suggest the universe is homogeneous and isotropic, meaning that it looks roughly the same in all directions and at all scales. This suggests that the universe extends infinitely in all directions.

However, the question of the ultimate fate of the universe and its eventual demise is a separate issue. According to current scientific understanding, the universe has a finite age and is expanding. It is believed that eventually, the expansion will continue to the point where galaxies move so far apart that they are no longer gravitationally bound to each other, and the universe will become a cold, dark and empty place, known as the "heat death" of the universe.

So, in summary, the universe can be infinite in size while still having a finite lifespan. The concept of infinity relates to the spatial extent of the universe, while the lifespan of the universe is a separate issue related to its eventual fate.

there has to be some infinite aspect to reality, since something cannot come from nothing, something exists, therefore there has always been something. which aspect of reality infinity applies to however, is unclear.

It doesn't need to, nothing already is something.
Even if it did, there is plenty of mathematical evidence that a full unit of something must result from functions purely of nothing.

Something that is unbounded has an open boundary, and the specific mathematical name for that type of boundary is infinity.
