First direct evidence for inflation

[Byblos]

Listening to that though Byblos - it does seem that your idea that we are living in the first universe is more feasible as the decay get more an more disordered as the space continues to expand.

It does, doesn't it. Keep in mind that to have uniformity, the value of lambda has to be as close to 1 as possible, as is the case in our universe. The thing is, with subsequent universes the value shifts away from 1 so any other universe will be less uniform than ours. It's really a matter of mathematics.

Let me know if you see anything that confirms that idea Byblos. If you are right then it could well be that God is maybe preparing a multitude of other universes for us that will keep us occupied when we gain immortality with a our glorified bodies.

Let's talk about the inflationary model first, what is it and what does it predict. According to Alan Guth, the father of the inflationary model, inflation is what put the bang in the big bang. It describes the prequel to the big bang. The theory postulates that repulsive gravity caused the initial conditions of the universe to expand with extreme velocity, on the order of 100 times faster than the speed of light. When repulsive gravity reaches its half life, it causes a bang, and poof a universe pops out. But because of the speed, this process doesn't stop, it repeats itself eternally, albeit with each half-life cycle being less frequent.

Forgive me for what might be a stupid question but how does each half life get less frequent? Can't get my head around that. Half life of what exactly?

Also if it is getting less frequent then surely by definition there will only be a limited amount of universes because the amount of time between each decay will eventually be eternal in a eternal inflation.

What I still don't really understand is - Did inflation happen after the big bang - or is inflation something that is happening and still happening outside out universe and the big bang was just the perception of our own universe starting due to a decay in the false vacuum?

Okay....Basically say you have a large lump of Uranium (1Kg). After a certain amount of time, half of the atoms of said lump will fission (Lose atomic parts of the atoms) DOWN into a different element.

(Am between finishing work and getting ready for bed, so ave time constraints in doing a web search for the list of things Uranium decays through)

Again, after another length of the same amount of time. The 0.5 Kg lump of Uranium will again fission.

This is what is a quick and simple, lay-man's understanding of what is meant by the "Half life" of atomic elements.

Much cheers to all.

- Did inflation happen after the big bang -

From what I understand of reading magazines such as 'New Scientist'? Yes.

- Is inflation something that is happening and still happening outside out universe -

Not sure if any one knows what is happening 'Outside' our Universe. The inflation WAS the Universe expanding at an accelerated rate. Again, as far as I think I understand the magazine's words.

Much cheers to all.

Looks like the smoking gun might be dust after all...

Thanks for the info.

A Huffington Post article on the multi-verse.

Just to add to the last couple of articles posted on the likelihood that these scientists jumped the gun:

Apparently another group working with the European Space Agency's Planck telescope will be publishing its results in the coming months. Should make for an interesting discussion (if they find anything; and if they don't?).

I agree with the article in that they should be more careful with announcements.
