Steven hawking proposes that information leaks into other universes? Shouldn't we be able to detect some leakage into our universe then?

The particles that make up our bodies are constantly interacting with other particles, so in effect they are being measured or observed by the other particles, so their wave functions are always collapsed to 1 location with the probability of them being elsewhere excruciatingly small, so this is why we do not suddenly find ourselves in the andromeda galaxy from time to time. However, if you have an electron in a perfect vacuum, nothing will be observing it, so it's wave function does not collapse so it is in all places at once.

That's a good point but then I think about the massive amounts of energy we get from the sun every second, and that only keeps us at an average of like 283K ( I don't know the exact average). I think it would drop pretty damn quickly without that energy.

Just for the record, if you were the size of an electron, nuclei would not resemble planets it would most likely be completely weird, quantum physics has taught us this

How does the black hole have enough money to pay back the loan? All it's savings are in a gravitational well so how can it just give some of that up?

Yeah I got you, sorry I wasn't very clear in my post. What I meant is that the universe wouldn't lend you the particles in the first place because it would know that you won't be able to pay them back

I like the bank analogy, but you can fool the bank into giving you $20 and then eat half of it, but you can't fool the universe into giving you two particles on loan then eat one of them and not be able to give the other one back. The bank doesn't know what you will do with the money after it lends it to you, but quantum mechanics and the universe are timeless, they won't lend you the particles in the first place because they know what's going to happen.

No worries, that is the formula for working out basic gravitational attraction, you have to divide the product of the masses by the distance squared, even if you have something a billion billion billion metres away ( 10^27m) and you square it ( 10^54), the formula will still say there is some attraction, granted it will be about a 10^50th of a Newton (ridiculously small), but it will never reach zero, no matter how far away it is.

This is all just speculation but here goes: The temperature would drop rapidly, so all water would freeze, including the water vapour in the air, soon enough, nitrogen would turn to liquid, then oxygen, so the atmosphere would not do too well there. Also, without the protection of the suns magnetic field, the earths magnetic field may not be enough to protect us from the particles out in interstellar space. Life would die extremely fast, we probably wouldnt make it to Pluto before we froze to death (I have no clue how far we would get, that's just a guess). I think the main thing would be the temperature drop.

F=GMm/r^2 That's the Newtonian equation for Gravitational attraction, as r increases, the force between the two decreases, but will never reach 0, as a fraction with all non 0 values in it cannot equal 0. So every mass attracts every other mass in the universe, just with very little force. I hope that's what you were after Also, you can never have completely empty space, there is always fields there, the Higgs field for example will take a non zero value when there is no matter or energy in the region (and it is cooled) so there is always somethin there.

Haha severian that was a good one

From what I understand, hawking radiation is when two particles are created, either by a photon momentarily splitting into an anti particle-particle pair, or an antiparticle-particle pair being created out of nothing (within the limits of the Heisenberg uncertainty principle). One of these particles falls into the event horizon and the other doesn't, so one particle is created out of nothing and the black hole loses a small amount of mass (black hole evaporation). This seems to me to be a little dodgy, it seems like quantum mechanics is being tricked. And as we have learnt from many many experiments, it cannot. For example, light from distant stars, coming in as a particle, people try and trick it by putting a double slit there and making an interference pattern. ( not a very good example I know as light is both simultaneously, but I hope you get the jist of what I'm talking about). Also I'm a little unclear on how the black hole loses a small amount of mass when a particle falls in, instead of gaining mass.

Firstly, I understand that electrons occupy no volume, so aren't they smaller than planck length? Also, do neutrinos occupy a volume?

I think it's a really nice idea, however non-living objects do feel time( not photons really but planets definitely) so they would definitely excite a theoretical time field.

Ok cool, so chromodynamics is similar to electrodynamics?
