You have it all wrong....I am quite attracted towards the concept of multi/parallel Universes, but we have no evidence at all for it...just speculation.
Unlike Guth's original Inflation model.

Well, then I officially retract my claims, and verify that there was no inflation field that transfers energy, and it was actually due to a transfer between gravity and anti-gravity as with the wording of the paper that I linked above... Happy now? Oh and of course as you know, anti-gravity is a well founded scientific principle, lol.

There is no difference in that aspect of the model in inflation and eternal inflation. Seriously though, I think that inflation could hint towards a different Planck Scale at the origin of the Big Bang, because I think he calculated his values from the expansion of the universe itself, that was wrong. Then it was very close, it may just be that it isn't the final theory, and it definitely is not because it proposes a lot of unexplained phenomena being present or possible.

It just means that he believes in the MWI instead of the Copenhagen Interpretation, and that is just a different view of the same mathematics. I don't think the other universes actually have any physical influence on our own universe in the theory.
 
Then 10^-43 seconds would be smaller than 10^-34 sec limit of the Planck Scale. Almost forgot that a larger number as a negative exponent would actually be smaller value. If Max Planck was right in his theory, everything smaller than that could just be erased from history and it wouldn't make any difference. Reality itself should round down to that value, as long as it is impossible for infinite sources of energy, and as far as I know relativity says nothing about its influences affecting the quantum mechanical world as they are incompatible theories.

^That's funny, cause the Planck Scale is 10^-33 cm and 10^-34 sec. The Big Bang would have started after 10^-34 sec of t=0. This wiki link is clearly wrong. There would have been no way inflation would have ended before this time. That time wouldn't have actually even existed or been able to have any impact on anything afterwards without a singularity.

The Planck/Quantum scale is at 10-43 seconds, or 10-35 mtres.[give or take a power]
And of course the BB started at t=0, while Inflation started at the end of the Planck epoch.[10-43seconds]
It's obvious your confusion stems from getting the time Inflation lasted for, mixed up with when it started.

No theories/models give us any description/idea of what happened, or what was going on from t=0, to 10-43 seconds.

Happy???Why?? :confused:
When the Superforce started to decouple, false vacuums and phase transitions were created.
I would hazard a guess and say false vacuums could be described as anti gravity...But I'm open for a better interpretation on that.

I could have sworn that it was 10^-34 sec in every book I read about it. Then I think Guth did assume that it was 10^-43. I used a mnemonic device that said that it was just counting up a number in order to remember that value. Then it does that if you give the distance in centimeters instead of meters. It makes me think there are actually two different values of the Planck Time floating around.

Quantum mechanics, gravity and relativity

So, where do these quantities come from? The speed of light c is the natural unit that relates time and space. G is the constant of gravity, and h is the constant of quantum mechanics. So the Planck scale defines the meeting point of gravity, quantum mechanics, time and space. Currently, we don't know much about this interaction, because gravity is so feeble that its influence on things as small as quantum systems is small.

Well, you asked for it. I think the inflation field is the effects of spacetime dilatation in relativity itself. If you assume that there was no mass at t=0, then there would have only been energy traveling at the speed of light. If that was true then all of space time would have been contracted to zero from that frame of reference. Then there would have had to been a free energy mechanism, that allowed for energy to intensify itself. Then the energy could be converted into mass. With the appearance of mass, space time would be less dilated due to it not being able to travel the speed of light. Then space time would have grown from the frame of reference of mass. Then as mass increased in the universe it would have moved slower and slower. Then the universe would have become less dilated and inflated at a rate relative to the increase of mass. Then I think this model could fit into working out like Guth's inflation model, but it would just have different reasons that his model lacks entirely. Then the free energy mechanism could have stayed in place and created the effect of the density of the universe not changing in early periods. Then this would have continued until light could no longer travel around the universe, as it can't today. Hence, rapid periods of inflation would have stopped when the universe is this size. Then dark energy could just be a result of the infinity at the speed of light in relativity. It would have had to grow infinitely in size since it started at zero.

"The Planck time is 5.4 x 10-44 seconds. (I'm wearing out the zero key on this keyboard, so I shan't write it out in full but you get the idea: it's brief.)" You said 10^-43 sec. This says 10^-44 sec. You just found another third value for it that wasn't what either of us said..

Well, I didn't see anything there that calculates the limit of the amount of energy required to measure that distance. In pop physics, I am pretty sure that it is 10^-34 sec that it would require an infinite amount of energy to measure. Maybe it is we are talking about different theories of the Planck Scale.

Again, I think you have mixed up the time and length components of the Planck realm.
Also as far as I know, there is only one stipulated Planck/Quantum realm by definition.
 
At first I thought this was 'family feud' forum.

Imagine a finite number of objects, occupying a finite volume of space, with no significant binding phenomena, such as gravity, em, etc. Introduce a small amount of energy which disperses throughout the volume thru interactions. After the objects move across the original boundary in random directions, they will continue to expand since there is nowhere else to go.

Expansion would seem to be unavoidable unless there is a force to regulate it.
As an alternative, the universe could have begun with a finite size, then seeded with energy to get it going.
 
Blogger claims BICEP2 team acknowledging possible error in discovery of evidence of gravitational waves

(Phys.org) —Adam Falkowski, a physicist working at CERN, on his Particle Physics Blog, is claiming that researchers on the BICEP2 team that uploaded a paper (First direct evidence of cosmic inflation) to the arXiv preprint server this past March have acknowledged to some in the science community that there may be a problem with their methodology. Members of the BICEP2 research team are denying Falkowski's claim, but the assertion has led to rumors on the Internet that the team may not have found evidence of cosmic inflation after all.

In the meantime, members of the BICEP2 team have been responding to the rumors and claim they are still confident in their results and that any gossip suggesting they have begun to doubt their work is wrong. Whether they believe their work is in jeopardy or not, is, of course, not really what's important—finding out if what they reported is correct is what matters, and that is going to take some time.

That's why I dislike 'blogs'. If you read
Killing the Straw Man: Does BICEP Prove Inflation at the GUT Scale?
http://arxiv.org/abs/1403.5166v1

then all the 'blogger bullshit' is reduced to a lie.

Agreed brucep, and was going to mention the blog aspect of this.....
I actually posted the article before any of the other alternative brigade could get hold of it and run with it.
You know how quickly they tend to grasp at straws and all that.
 
I would bet the next big discovery here will be that they could use the same equipment to detect gravitational waves from their microwave oven using the same equipment...

Didn't anyone ever tell them that they had a completely different observatory dedicated to finding gravitational waves with no success?

Cosmologists cast doubt on inflation evidence
Mar 25, 2014 by Jason Major, Universe Today:

It was just a week ago that the news blew through the scientific world like a storm: researchers from the BICEP2 project at the South Pole Telescope had detected unambiguous evidence of primordial gravitational waves in the cosmic microwave background, the residual rippling of space and time created by the sudden inflation of the Universe less than a billionth of a billionth of a second after the Big Bang.

And so, for better or worse (just kidding—it's definitely better) this is how science works and how science is supposed to work. A claim is presented, and, regardless of how attractive its implications may be, it must stand up to any other possibilities before deemed the decisive winner. It's not a popularity contest, it's not a beauty contest, and it's not up for vote. What it is up for is scrutiny, and this is just an example of scientists behaving as they should.
Still, I'd keep that champagne nicely chilled.

Talk about dramatic flair

The mainstream does what it does ….....

If science really did what it does , then it would publish all theories presented , regardless

And have a publication , that is public , that is dedicated , to all theories , approved or not
