be -infinity to +infinity?

Or even vector calculus can be used to determine area?

is it possible to find the area ofuniverse

Are we in a universe or a multiverse(and if so what type)? Question is highly subjective...depends on who you ask

How could you build a 4-volume out of R^2? Should it be conformal?

we consider universe to be infinite,then consider volume integral,having limits from -infinity

to +infinity--we can still find the volume.

but if the universe is finite,we do not know its particular shape i.e ellipsoidal or circular,

in order to calculate?But since we know the universe is expanding,it has to be finite.

That doesn't follow. An infinite universe can be everywhere expanding.

But to what purpose? If the universe is infinite, how could its volume not be infinite? And just exactly what would you integrate? This seems like a lot of work to get a trivial result.even if we consider the universe to be 3 dimensional,volume can be found,,as you say,if

we consider universe to be infinite,then consider volume integral,having limits from -infinity

to +infinity--we can still find the volume.

There are not serious questions and there are serious questions. This is one of the latter.

Dick, did you mean to say former rather than latter?There are not serious questions and there are serious questions. This is one of the latter.

Dang. I had a one in two chance of using the right word by accident and I blew it.
