If our universe is just one of many, that could explain why it seems so exquisitely tuned for our existence.
If dark energy, the repulsive influence hiding in empty space that speeds up the expansion of the universe, were just a little stronger, matter would be flung apart before galaxies could ever form. If it were attractive instead, the universe would collapse. But it is shockingly puny, and that's weird, unless our universe is one of many in the multiverse.
Compared with what we might expect from quantum theory, dark energy is 120 orders of magnitude too small. So far, no compelling explanation for that discrepancy has emerged. But if the multiverse exists, and dark energy varies from bubble to bubble (see main story), that might not seem so strange.
That's because our own universe might be an oddball compared to most bubbles. In many, dark energy would be too strong for galaxies, stars and planets to form, but not in all. "Plenty of them would have energies as small as what we observe," says physicist Alan Guth of MIT.
That still leaves us struggling to explain why our universe is one of the special ones. Our best answer so far, Guth says, is a philosophical headache: our universe has to be special because we are alive in it. In a more average region, where dark energy is stronger, stars, planets, and life would never have evolved.
That could mean life only exists in a sliver of the multiverse, with any conscious beings convinced their own slice of space is special, too.
How can it be another universe if we can see it, interact with it? Not very universal of it.
So there’s a photo of this or what?
There are mirrors at the end of the universe to make it appear larger.
They basically invented and are pushing the multi-verse theory in order to explain why the entire universe is fine tuned for our existence. The alternative is to believe in a creator God. The odds against the universe being this way, if it's the only universe, are nil. Therefore the multiverse...if there's an infinite number of universes then gee did we ever get lucky.
“If our universe is just one of many, that could explain why it seems so exquisitely tuned for our existence.”
Ah, no. Our existence conforms to the constraints of physics in the universe. The universe is not tuned for us, rather we evolved within its constraints. Tuning implies intent with an objective, smuggling in the premise of purpose.

we must ensure the survival of our universe...we cannot have a universe gap...we should draw up invasion plans immediately...
hold on...maybe in this other universe there are no liberals to fark everythign up..might be worth moving there...or better still expoert all of ours there...
save for later reading
What does Dr Cooper say about this?
I find the explanation in Exodus far more plausible then this one. Physics is built on facts, not faith. The author of this has a far more implausible faith than belief in God.
In Him, we live and move and have our very being.
If you can access another universe in any way it’s not another universe, it would be part of this universe.
My Father’s house has many rooms; if that were not so, would I have told you that I am going there to prepare a place for you? John 14:2
our “universe” is shaped like a soccer ball
surrounded by like soccer balls (other universes)
and this explains the movement of dark matter being pulled by the gravitational forces in these other universes...
