There could be a mind-boggling smorgasbord of universes Linde offers a simple but mind-bending answer. In the case of the universe, the matter goes on one side of the scale, and has to be balanced by Why not nothing. This is the branch of physics that deals with very small things: Still, it seems like a big leap from an infinitesimal space-time bubble to a massive universe that hosts billion galaxies.
If one space-time bubble popped into existence and inflated to form our universe, what kept other bubbles from doing the same?
Linde says eternal inflation is not just the ultimate free lunch: Gravity might be ten times stronger or a thousand times weaker, or not exist at all. That inflating space can spawn more universes, with yet more inflating space around them. View image of The cosmic microwave background Credit: When a new universe stops inflating, says Linde, it is still surrounded by space that is continuing to inflate.
As weird as it seems, inflation fits the facts rather well. Pretty much every ancient culture came up with its own creation story - most of them leaving the matter in the hands of the gods - and philosophers have written reams on the subject.
Actually your teachers left out a crucial point: In other words, little bubbles of space and time can form spontaneously.
By Robert Adler 6 November People have wrestled with the mystery of why the universe exists for thousands of years. But for that we need another trick: Da Sal, CC by 2.
It had to happen, they say, because "nothing" is inherently unstable. View image of It may not look flat In quantum physics, if something is not forbidden, it necessarily happens One thing they have found is that, when quantum theory is applied to space at the smallest possible scale, space itself becomes unstable.
It could curve back on itself like the surface of a sphere, in which case if you travel far enough in the same direction you would end up back where you started. This idea may sound bizarre, or just another fanciful creation story.

When the expansion finally slowed, the force field that had powered it was transformed into the matter and energy that fill the universe today.Why is there something rather than nothing?
That’s the big question we’re asking in this week’s show.
It’s an odd question that could be thought of as either supremely profound, or supremely silly. No, but seriously.
Why is there something instead of nothing? Last night, as I was creeping around the internet at am while the adults of the world slept, my eyes glanced by the headline, “Why is there something instead of nothing?” on the sidebar of a. I aint got time for your politics Or your masqueraded machavellian tricks Goodbye, you know I aint got time Don't deny it it's abuse of the cross.
Particles from empty space. First we have to take a look at the realm of quantum mechanics. This is the branch of physics that deals with very small things: atoms and even tinier particles.
Why Not Nothing? Lyrics: I ain't got time for your politics / Or your masqueraded Machiavellian tricks / Goodbye, you know I ain't got the time / You don't deny it it's abuse of the cross / Let's.
Then why is there something rather than nothing? Because something is the more natural state of affairs and is thus more likely than nothing-more than twice as likely according to one calculation. We can infer this from the processes of nature where simple systems tend to be unstable and often spontaneously transform into more complex ones.Download
