Wendy Freedman - What would Multiple Universes Mean?

Is there more than one universe? According to current cosmology, our entire gigantic universe is only one of innumerable universes, each universe like one tiny bubble in a limitless ocean of universes. It's called a 'multiverse' and it radically expands the size of reality.

Light cannot travel between universes...but in theory the graviton might (if it exists) and with the discovery of gravity waves we may in theory be able to test the multiverse, no?

[jamesruscheinski]

Could multiple universes be in different dimensions of space-time?

[JoelBondurant]

Nervous about not understanding something? A big fan of the death cults this guy.

Wow! Compare this rational level-headed woman to Frank Tipler. Night and day!

These people have no idea how we're created. They have to guess because they don't know what us saints know.
