Please note that I'm priorly assuming in this thought experiment that the space in the universe is infinite:

( no matter the time being limited to only 1.0 second in the experiment, or time being infinite , for this point below , doesn't matter, even 1 infinitesimal of a fraction of a millisecond would be enough, of course we need at least a little bit of time, because with No time at all there is no space to speak of, much less infinite space )

All the infinite universes that exist and we are inside all of them right now( it is only 1 universe, but all "universes" exist in this infinite universe, side by side, They don't need to be "parallel", they can be side-by-side, it means, they don't occupy the same space, but we don't need it, because we have Infinite space(more then enough)

So we have a lot of space, and in a given second, in all this space, every possible thing is happening right now, but very far from us, light-years is too small to measure the distances we are talking about ,

actually is impossible to measure how big even with units bigger then Light-Years...

...(1 Light-Year is the distance you go in 1 year at light speed, of course this is redundant info, but some readers may not know it).... And is impossible to measure because with any unit of distance because the distance here is Infinite,...

So everything that you can and Can Not...

(infinite times more things then you can ever imagine if you had a infinite life)...

...Is happening at this very millisecond...

...Or a in fraction of a millisecond...

A infinisecond would be enough to all infinite possible things to exist, distributed by our infinite space...

Of course this only, and Solely only If the Space of the Universe is really infinite....

I think it is, but even Einstein was not so sure, so...

But I am sure Time is infinite, so 1 square meter of space is enough for every possible imaginable and unimaginable thing to exist ( well all every possible things smaller then 1 square meter) If the time is infinite, It means "for Eternity" or On Eternity, everything will happen)

you only need a square nanomilimeter for that (but all infinite things inside the given space of the nanomilimeter)...

Please Remember that you can shove/fit/stuff or insert more then 10 infinite universes inside 1 single infinite universe, because infinite is infinite.

Now replace the number 10 above by infinite.

you can fit an infinite number of Infinite universes inside a single 1 infinite universe, as the simple Math proves.

So okonimiaki3000 is right when he says what he says.

And your comment was Snarky and Clue-less, sorry to say that.

If you don't have arguments to support your claims, better avoiding doing exactly the Opposite ( here is Exactly the Inverse) The Opposite of what you were trying to do with your pointless comment, trying to sound Smart and sounding exactly the opposite...

Sorry. But you deserve it for your Snark.

All of this is because when you Multiply anything, even very small, by infinite, the result equals infinite.
