It is finite in terms of energy cannot be created or destroyed.

There is no net gain or loss.

As for infinite possibilities, I do not find that to be tenable. I believe that nature is the way, not in the possibility for example that it is not the way.

There doesn't seem to be any real evidence that the universe is infinite in an absolute sense where everything imaginable will be.

Can you explain how infinite possibilities are possible?

I don't see.

I find some concepts of infinity to be incredibly rational, the same with finity, they are to me two sides of the same phenomena and mutually entail one another.

But I don't believe in linear time, so infinity for me is a constant, an instant and a singularity, that is that it has finite and infinite properties that beget each other.

Consider the 2D shape of a ring, it is finite and infinite, but it is not "unlimited" and I do not view infinity as unlimited. Consider the value Pi, it is infinite and yet a single finite value, it goes on forever but is not unlimited. For me unending does not mean limitless.

To me it makes a lot of sense. To say the universe will contain anything we imagine places us at the center of existence. It makes sense that one can imagine infinite things that can never be, and infinite things that can be, but not that all that one imagines will or will not be.

It is a welcome deviation.

I do think that there is enough data to come to rational conclusions about many things, including infinite and finite values and their relationship to one another.

I find any belief that supposes that we determine the nature of the universe to be egotistical. We certainly influence, but I do not believe we are here for existence or that existence is here for us. This is what I believe.

I can imagine many things that cannot and will not be. But then I have already shared that I do not view infinite as unlimited in an absolute sense. The linear number system goes on forever, thus it is infinite, but it is based on a procession of simple units of 1, if it was unlimited in an absolute sense then there could be a number value in the sequence that is not made by adding 1 to the previous number, but this is not the case. The infinite is based upon the finite, all numerical values are composed of singular parts and a singular whole.

There is the classic argument of taking a single given space and dividing it in half, and halving the halves etc, that this division can be made theoretically infinitely. The mistake is to assume that there is then, in a single increment of space; infinite space. Logically it is said there can be because one can theoretically divide it into infinite sub-units, however there is still no net gain or loss, being able to divide the space into infinite sub-units does not mean the space is unlimited or limitless. Rather it is precisely because it is finite and limited that it can be divided. If it was an infinite sized space, it could not be divided at all because half of infinity is still infinity.
