Astronomers Find First Evidence Of Other Universes

Our cosmos was “bruised” in collisions with other universes. Now astronomers have found the first evidence of these impacts in the cosmic microwave background



There’s something exciting afoot in the world of cosmology. Last month, Roger Penrose at the University of Oxford and Vahe Gurzadyan at Yerevan State University in Armenia announced that they had found patterns of concentric circles in the cosmic microwave background, the echo of the Big Bang.

This, they say, is exactly what you’d expect if the universe were eternally cyclical. By that, they mean that each cycle ends with a big bang that starts the next cycle. In this model, the universe is a kind of cosmic Russian Doll, with all previous universes contained within the current one.

That’s an extraordinary discovery: evidence of something that occurred before the (conventional) Big Bang.

Today, another group says they’ve found something else in the echo of the Big Bang. These guys start with a different model of the universe called eternal inflation. In this way of thinking, the universe we see is merely a bubble in a much larger cosmos. This cosmos is filled with other bubbles, all of which are other universes where the laws of physics may be dramatically different to ours.

These bubbles probably had a violent past, jostling together and leaving “cosmic bruises” where they touched. If so, these bruises ought to be visible today in the cosmic microwave background.

Now Stephen Feeney at University College London and a few pals say they’ve found tentative evidence of this bruising in the form of circular patterns in cosmic microwave background. In fact, they’ve found four bruises, implying that our universe must have smashed into other bubbles at least four times in the past.

Again, this is an extraordinary result: the first evidence of universes beyond our own.

So, what to make of these discoveries. First, these effects could easily be a trick of the eye. As Feeney and co acknowledge: “it is rather easy to fifind all sorts of statistically unlikely properties in a large dataset like the CMB.” That’s for sure!

There are precautions statisticians can take to guard against this, which both Feeney and Penrose bring to bear in various ways.

But these are unlikely to settle the argument. In the last few weeks, several groups have confirmed Penrose’s finding while others have found no evidence for it. Expect a similar pattern for Feeney’s result.

The only way to settle this will be to confirm or refute the findings with better data. As luck would have it, new data is forthcoming thanks to the Planck spacecraft that is currently peering into the cosmic microwave background with more resolution and greater sensitivity than ever.

Cosmologists should have a decent data set to play with in a couple of years or so. When they get it, these circles should either spring into clear view or disappear into noise (rather like the mysterious Mars face that appeared in pictures of the red planet taken by Viking 1 and then disappeared in the higher resolution shots from the Mars Global Surveyor).

Planck should settle the matter; or, with any luck, introduce an even better mystery. In the meantime, there’s going to be some fascinating discussion about this data and what it implies about the nature of the Universe. We’ll be watching.

If this is true, the word universe is going to need a new definition.

u·ni·verse
ˈyo͞onəˌvərs
noun
1.
all existing matter and space considered as a whole; the cosmos. The universe is believed to be at least 10 billion light years in diameter and contains a vast number of galaxies; it has been expanding since its creation in the Big Bang about 13 billion years ago.

Not necessarily. The concept of a "multi-verse" is not anything new. So not so much a re-definition so much as a clarification.

I can't even begin to comprehend other universes.

Did you get a picture dave?

How much to send HCF to another universe? I got $5 on it as long as there is no internet access.

+5

The Chiefs are still celebrating their 4 SB win in a row in another Universe.

not to quibble but we just discovered a 13.6 billion year old universe.:p

I'm still having trouble comprehending how you blow a 28 point lead in the second half...now this ? II'm done.

In another Universe, the Chiefs kept rolling in the 2nd half.


We got the shit Universe. I hope my double in the good Universe dies in an AIDS fire.

Cool. Looking forward to the next data set.

In that case, how much to send me to another universe? HCF can ****ing have this one.

No shit...

Hopefully in that other universe the Chiefs have been to the Superbowl a couple more times

Here in America ****ers can't vote without identification but yet we listen to some shit cooking in the microwave and we immediately ascertain it's age and what it is.

I call bullshit. The only thing I hear in my microwave is awfully similar to Joe's Apartment.

Actually I just got this one...

I'll bet $100 cash money that in one of those other universes that 3rd and 48ers does the laundry.

Most scientists think<!--[if gte mso 9]><xml> <o:OfficeDocumentSettings> <o:AllowPNG/> </o:OfficeDocumentSettings> </xml><![endif]--> parrell universes are more likely than time travel. So you may get your wish.

Lead by a white chocolate penii

This isn't in Science is cool thread so it sucks.

If anyone wants to completely melt their brain, dive into Parallel Universes.


They are Infinite.

This is too cool to just live there...

Shit, I'd bet cash money he does it in THIS universe, but also admits to it in the other one.

There's a parallel universe out there where everything is exactly the same except Hawk and Omaha switched places for the women they find attractive.

I'd be willing to bet that he does it in this one and if he doesn't his wife beats him like a red headed step child.

+500

Hawk: Too Fat!

There is a Universe in which Como is right.....




....about EVERYTHING.

Bizzaro world !!!!

30 years ago our best scientists thought black holes were a myth.

Some current scientists theorize that our entire universe may be a black hole or its a Star Trek like gateway to another universe.

Now, Stephen Hawking (maybe the smartest man on the planet) came out recently with a paper that said the event horizon may not be so clear. That its an apparent horizon. Which means in theory a black hole can show up anywhere.

Bottom line in 10 years, what we know will be totally different.

Thats the beauty of Science. Always learning more and more about our surroundings. Its a damned good time to be alive my friends.

so bad ass.:thumb:

Yeah thats why I'm excited for my son. Hell, I've rediscovered my long ago lost love for astrophysics. The next 50 years is going to be an amazing time to work in the field.

100 years ago everyone thought our galaxy was our Universe until Edwin Hubble discovered that the Andromeda nebula was another galaxy. Now Scientist say that there may be over 300,000 galaxies in our Universe and each one may have over 300,000 stars. The largest Galaxy found so far has 60 million stars. What if there are over 300,000 Universes or more beyond ours. If God is infinite maybe the multiverse is also. Just saying. :hmmm:

That doesn't really look like a cosmic bruise to me.

according to Stan Lee we are universe 616

in DC we are earth one, but there is an earth prime
so it gets confusing
and then there is the bleed...

So fascinating...but makes you a little dizzy trying to make sense of it.

Wait

You're an astrophysicist?

Why haven't you helped me with my ****ing astronomy?

This is what I' saying. I just have no way of contexualizing any of this.

Keep posting this stuff Dave. I've become increasingly interested in it the last couple of years.

The bigger question is what's beyond those?

That's a really interesting stuff.

I know.


28 points........

I'll add 5 and empty the couch cushions.

Dave's a good dood and knows his shit.

maybe he'll post a pict of his mother ****ing homemade observatory in his house.

This should have it's own thread, I hate all mega threads actually, but am partial to the Science is cool thread.

220, 221, whatever it takes.

For a start, how is the existence of the other universes to be tested? To be sure, all cosmologists accept that there are some regions of the universe that lie beyond the reach of our telescopes, but somewhere on the slippery slope between that and the idea that there are an infinite number of universes, credibility reaches a limit. As one slips down that slope, more and more must be accepted on faith, and less and less is open to scientific verification. Extreme multiverse explanations are therefore reminiscent of theological discussions. Indeed, invoking an infinity of unseen universes to explain the unusual features of the one we do see is just as ad hoc as invoking an unseen Creator. The multiverse theory may be dressed up in scientific language, but in essence it requires the same leap of faith.

— Paul Davies, A Brief History of the Multiverse

Good point. :thumb:

and this is called The Twilight Zone

Which means the Chiefs are actually winning the Superbowl every year in an infinite amount of universes.

NOOICE!

LMAO

In that universe, AIDs fires are one of the more honorable ways one can die.

Lol....yes! Aids fires

The Cheufs have won all 48 Super Bowls in a universe somewhere.

I wonder if the chiefs have won a playoff game in the past 19 years in any of the other universes

we're the laughing stock of the universe.

Fascinating

Still can't wrap my mind around this.

So if our bubble is just one of many, does that mean we are being watched like the Truman Show? We are famous!

Also, does this imply that we can get "out" of this bubble and move to another one? Is our bubble touching another bubble somewhere? Is there a definitive divider/border between bubbles? Some kind of membrane that has to be pierced? Do wormholes go just to other galaxies or other bubbles? If the bubbles don't touch what is in the gap between bubbles? Are these bubbles the parallel universes or simply part of this one?

Just a hobbyist. A pedestrian one at that. I can understand something someone wrote but can't create it from scratch. Kind of like I can read a book but not write one.

My son is getting there though. You want to see what he charges?:p

I was just getting around to understanding how big ours was.

This gif just keeps going and going.

Prepare yourselves:

Pretty incredible and tough to even comprehend.

How far away is the "edge" though? 13+ billion light years? I'm not sure we'll ever see it..

That's my thought too.

Someday, maybe. But not in our life times.

I used to be super into the planets, solar system, universe, etc when I was younger. May have to break outmy old telsescope and nerd out.

I used to eat mushrooms and go on science trips.

Damn those where the days.

I've always thought how cool it would be to be alive when we discovered that there were galaxies other than the Milky Way. If we are on the cusp of discovering other universes - that would be pretty cool.

Good way to get murdered by the church!

BLASPHERMERER...ER ?

WWJD?

How much to just get to the Universe where everything's the same, but Derrick Thomas puts on his damn seat belt?

That can't be TOO far away?

If our universe is expanding and there are others surrounding/at the edge of ours, what are we expanding into? Are we merging with another universe?

Getting ready for some more bruises. Like Ike and Tina bruises.

Damn, how old are you?!?

Pollux looks like pure evil. We need to figure out a way to explore these crazy stars.

You have Jupiter Saturn and the Orion Nebula that are easy views right now.

About 80-90 based on that statement LMAO

Check this out. Morgan Freeman's Through the Wormhole episode about that. Full video here:
