There’s good work coming out of Caltech this month supporting the idea – familiar to readers of FQXi Community – that the universe in which we live is the result of a spontaneous quantum fluctuation. This is the scenario often referred to in the press as “creation out of nothing,” a catchphrase that makes me cringe. Indulge me for a moment on this.

To put it flatly,...

nothingness is the word we use for what rests over the horizon of retro causality. it's not what it is, it's just what it looks like!

i've always had an intuitive discomfort with the idea that the universe formed out of "nothing"; how could something come from nothing?

'“the peach trees are” has meaning, which, when you think about it, cannot be demonstrated.'

-why can't it be demonstrated that the peach trees are?

-does it matter if they are georgia peaches. does it matter if they are ripe?

'“Three of the peach trees are”'

-does not say the the other peach trees aren't.

i'd rather have the three silver coins in my pocket, than any number peach trees, unless the peach trees aren't.

my goal in life is to be a married bachelor.

'spacetime, which we offhandedly refer to as “nothingness...”'

-physicists refer to spacetime as nothingness? or the media does? is it true that spacetime cannot exist without gravity?

your non-christian readers need an explanation for "creation ex nihilo". you scientists keeps forgetting that not everyone is christian. but it sounds latin to me, so i'm guessing it comes from italy. the universe came from italy?

the pope does not want hawking to study the beginning of the universe, because the church is afraid we won't find god there, and that would be bad for business. that's why the pope said martians are god's aliens. i rue the day when a crucifix lands on mars.

My point. If "nothingness" is thought to do *anything*, then the term no longer has the meaning it was originally given (granting for the moment that such a meaning is coherent).

-why can't it be demonstrated that the peach trees are?

Because any attempt to demonstrate the proposition will result instead in demonstrations of specific attributes: the peach trees are here, in my hand; the peach trees are made of hydrocarbons; the peach trees are clearly visible to you and me both; and so on. The sentence claims something *other* exists than the attributes, of which it lists none. Or, to say it in another way, it claims that if we removed all attributes from the peach trees something would still remain: their essence. This is an assumption often made by medieval, but dismissed by modern, philosophers.

-does it matter if they are georgia peaches. does it matter if they are ripe?

Nope.

'“Three of the peach trees are”'

-does not say the the other peach trees aren't.

True. So what has been said? If existence were a predicate like other predicates, we could presumably assign it to some peach trees and not others. But then we wind up with, "These peach trees are, but those aren't."

i'd rather have the three silver coins in my pocket, than any number peach trees, unless the peach trees aren't.

I love this. Anyway, you do have peach trees in your pocket. The only reason you don't feel them is that they aren't.

-physicists refer to spacetime as nothingness? or the media does?

Oftentimes the media does. Cosmologists, for their part, talk about universes emerging from nothing as a kind of shorthand for a quantum situation we don't yet understand.

is it true that spacetime cannot exist without gravity?

Other way around, I think. Mass warps spacetime and results in the phenomenon we call gravitation, so gravity cannot exist without spacetime.

Could spacetime exist without mass? I posed this one once in a previous blog. It seems conceivable that there are universes (assuming we live in a multiverse) that have three spatial dimensions but contain no mass. But the spacetime would still have a certain energy associated with it, which would be equivalent to mass . . .

your non-christian readers need an explanation for "creation ex nihilo".

"Out of Nothing." It's not specifically Christian, just Latin.

you scientists keeps forgetting that not everyone is christian.

Mea culpa

but it sounds latin to me, so i'm guessing it comes from italy. the universe came from italy?

Any point can be considered the center of the universe, so I suppose we could choose Italy.

I just did a posting on this very web site where they are talking about a contest and I was hopping I could qualify and its also related to this subject so I wont repeat to much of it here. The alternate theory does look at what would happen if time dilation caused by gravity would contract matter in such a way that the surrounding space also gets expanded and if its true would mean that any creation of a black hole would become at least universe like.Then what happens if you try modeling what would happen if two neutron stars were to come close enough together to revert into a black hole and remember that neutron stars can convert even iron into neutrons. Remember also that iron originally is the very last end product of any nuclear reaction so going lighter or heavier only uses up energy and the energy needed to pull a neutron star apart so the free neutrons can revert to protons or hydrogens again will also not gain you any energy advantages.Its that darned second law again.But if creating a black hole out of our older neutron stars was to causes the space to expand guess what happens.Thats right our neutrons now have a free space to convert to protons with a half life of about 12 minutes so you can get hydrogen from iron assuming this theory is the correct one.

But how do you get a universe out of just the mass of a few neutron stars well remember the expansion is fast if you could observe it from inside the newly created black hole.Really fast.Try modeling this from the prospectives of the two most distant particles to see what I mean.Its probable the bayronic numbers are not conserved with expansion that fast.Yes it does mean a lot more mass than the original amount but not from a singularity and not exactly ex nihilo.I would guess that this alternate theory just gives the same predictions as those of inflation theory.Look for my other posting with link info.
