Infinite and Multiple Universes (evidence and lack thereof)
Infinite universe

If the universe was infinite, there would be an infinite copy of 'bubbles' that are exactly the same as our observable universe. This is because there is only a finite way you can arrange all the particles and energy in the universe. Essentially it's a type of multiverse.

By measuring the 'shape' of the universe, we can determine whether or not the universe is infinite. Here's how: According to Einstein's theory of General Relativity, space itself can be curved by mass. As a result, the density of the universe — how much mass it has spread over its volume — determines its shape, as well as its future.

Astronomers have used trigonometry and the cosmic microwave background radiation to determine that the universe is flat. https://www.space.com/34928-the-universe...-what.html

With a flat universe is the possibility of an infinite universe. There has been no further evidence.

Multiple universes

By using the cosmic microwave background radiation (again) astronomers have found something that could be evidence of parallel universes, but there could also be other explanations.

http://www.independent.co.uk/news/scienc...43216.html

There has been no further evidence

So, what do you think? Is there an infinite number of infinite universes? I like the idea, but until solid evidence comes along, I have to remain skeptical.

RE: Infinite and Multiple Universes (evidence and lack thereof)
I wrote about this a few years back. cjlr didn't say I was wrong therefore, I must be right. Obviously.

It's to do with time.

In other parallel universes, the speed of light is faster than our speed of light (in our universe) and in other universes it's slower.

We will only ever be able to 'see' anything in these other universes when 'their now' and 'our now' align. Otherwise, they will either be forever receding into our history or advancing into our future.

The alignment of a 'now' scenario is when a newer faster universe and an older slower universe coincide on the same timeline. For a fragment of a moment (foam) the two become one allowing a matter/anti-matter singularity.

Of course, if there are an infinite number of universes then these singularities are happening all the time.

Thus, cosmology has built-in irony. Which is nice.

The other interesting notion is, as the prophet Douglas Adams noted, none of us are getting any ...

The Hitchhikers Guide to the Galaxy Wrote:The Hitchhiker's Guide to the Galaxy's definition of "Universe":

The Universe is a very big thing that contains a great number of planets and a great number of beings. It is Everything. What we live in. All around us. The lot. Not nothing. It is quite difficult to actually define what the Universe means, but fortunately the Guide doesn't worry about that and just gives us some useful information to live in it.

Area: The area of the Universe is infinite.

Imports: None. This is a by product of infinity; it is impossible to import things into something that has infinite volume because by definition there is no outside to import things from.

Exports: None, for similar reasons as imports.

Population: None. Although you might see people from time to time, they are most likely products of your imagination. Simple mathematics tells us that the population of the Universe must be zero. Why? Well given that the volume of the universe is infinite there must be an infinite number of worlds. But not all of them are populated; therefore only a finite number are. Any finite number divided by infinity is zero, therefore the average population of the Universe is zero, and so the total population must be zero.

Art: None. Because the function of art is to hold a mirror up to nature there can be no art because the Universe is infinite which means there simply isn't a mirror big enough.

Sex: None. Although in fact there is quite a lot, given the zero population of the Universe there can in fact be no beings to have sex, and therefore no sex happens in the Universe.

However, in a parallel-universe scenario, if we could predict the 'now singularities', imports and exports might be possible

... and sex would be feasible if very brief. Much like it is already.

I'll wait for the evidence for an infinite amount of time.

Perhaps some experiment gone wrong....

Or that Eden was an alternate universe, explaining why no one can find it.
