Assuming it stands up/can be reproduced:

This announcement contains quite a bit:

The first detection of gravity waves.
Evidence for a new scalar field.
Solves a few fine tuning problems.
Extends the model of the universe almost to the "instant of creation".
And lots more I can't even think of I'm sure.

It's gonna be a big one...

hoping that it an be verified by another team/means, always good to refine the cosmological model (even though it gets too complicated for most), some more articles:

https://www.simonsfoundation.org/quanta/20140317-possible-echo-of-big-bang-detected/

both touching on some other issues and there is also the more general

for all those who want to read up on the details, there are two links to the (draft) paper of the bicep2 team which is to be submitted to a journal:
http://arxiv.org/pdf/1403.3985.pdf or http://bicepkeck.org/b2_respap_arxiv_v1.pdf

but great disappointment for our highly informed specialists
there is neither any evidence of demons or angels, nor turtles or pyramids

Why be an arrogant jerk? Just save your sarcastic mockery for when you worship in the temple of your flying Spaghetti monster :P

seems i have hit a raw nerve, wonder why :)

nah, seems you know more about the fsm than i do - so i leave it in your sphere of interest
perhaps you find more valuable information in the op of http://forums.d2jsp.org/topic.php?t=70422296&f=90&v=1

So ultimately this means if we shrink it down billionths of a proton in size there has to be surrounding matter which gives proof of something outside the observable universe.
There also has to be something that sparked the exponential growth?

Yes you are right, this is connected to the other topic (with the red sphere).

There is a solution of general relativity which describes a negative pressure material which produces more repulsive gravity than it's mass creates attractive gravity---resulting in a net repulsion--- . This theoretical particle (never been detected of course) is called the inflaton (a play on the word inflation).

The hand-waving goes something like this:
  • Universe in unknown state, but small enough to be thermalized.
  • Creation of a virtual inflaton
  • Rapid expansion begins which is a run away process while the inflatons are present
  • decay of inflatons into normal matter that we see today
  • rapid expansion comes to a halt

It's a nice fairy tale story that has been cooked up to explain how you can get a universe that looks more or less like what we see today from essentially nothing, without violating any laws of physics (quite an accomplishment, even for just a story). The shocker is that the pretty good evidence for the bolded part was just found.... making it a bit more than a fairy tale (there has been lots of other less direct evidence for inflation that has been known for years of course).

Rah, not a raw nerve, just callout bigoted nonsense when I see it. Seems you have an affinity for trying to put others down to boost your own self esteem? If someone was attempting to make a ridiculous argument against a scientific position it would be understandable, but your post show no such thing. Just like your retort here, connecting dots that don't exist to somehow justify an attempt at insult to elevate awareness of your own keen wit :thumbsup:

Now this is an excellent Example of Scientific reasoning without any need to throw unsolicited barbs. The comment stands on its own foundation, not artificially inflated by stepping on someone else's toes. brmv, you should try this sometime....

That theory requires that the multiverse itself has a beginning.

A great quote from WLC that i'll copy here:

Quote
Speculative theories, such as Pre-Big Bang Inflationary scenarios, have been crafted to try to avoid this absolute beginning. But none of these theories has succeeded in restoring an eternal past. At most they just push the beginning back a step. But then the question inevitable arises: Why did the universe come into being? What brought the vacuum state into existence?

Well, unless you’re willing to say the universe just popped into being uncaused out of absolute non-being, there must be a transcendent cause beyond space and time which created the universe. Clearly, then, God’s existence is more probable given the beginning of the universe than it would have been without it.

ah yes, Christian apologetics, now that is REAL science... Might want to ask them to amend that statement "speculative theories", lol.
