Fish in a Barrel: I don't get how we can see this far back. Unless the universe has been expanding at a significant fraction of C since the big bang, shouldn't that light have passed us by long ago?


I just crunched the numbers and I came up with 80085

dragonchild: ambassador_ahab: So how did the tiny thing that expanded into our universe come into being?

I've heard some pretty interesting theories. One is that the Big Bang was basically (basically, basically, VERY basically) a whopper of a quantum fluctuation, one that would (on average) happen once every (incomprehensibly ridiculous number) years. The odds of this happening are so low that it's far less likely than sentience to emerge from the vacuum of space itself. It's so absurdly unlikely that critics have pointed out that the odds are practically zero, but the counterpoint there is that we only need for it to happen once in order for there to be selection bias. After all, we have no insight as to how much time the universe did not exist.

Shazam999: buck1138: ambassador_ahab: buck1138: What does gamma equal when v=c?

*Raises hand*

1/SQRT 1 = 1

So if v=c what does v^2/c^2 equal?

42?

dofus: Let's suppose the astronomers turned their equipment in the exact opposite direction and discover galaxy 'B' at the same distance.


If they did that, they would see the ground.

ModernPrimitive01: /I don't care about your lifestory, just don't want to see an otherwise healthy human mind fall into delusion


I like you.

MrPenny: ambassador_ahab:
Well, you develop the working Broussard drive, and I'll totally hop on in.

I think it's the Alcubierre drive that's got engineers all tumescent lately.


Engineers usually aren't delusional since they are the ones stuck actually building things. The only ones tumescent about a bunch of math describing impossible combinations of non-existent materials and magical quantities of energy are people who think sci-fi is real.

lohphat: Now apply that to the huge 3D "maps" of the universe.


I think I have it! God bought a 1:1 3D printer 14 billion years ago!

mongbiohazard: Nonrepeating Rotating Binary: Nope. God created that galaxy 6,000 years ago and strategically placed all the photons as if they had come from it billions of years ago.

That God fellow is a clever bastard, ain't he?

Not only clever, but also utterly untrustworthy. What you've described is a god who is willing to literally fark with the entire universe just to deceive us. That is not a being who you can trust on ANYTHING and should not be worshipped.


Hold my ambrosia, and watch this!

Clash City Farker: Did you ever think maybe science is wrong about all that origin stuff?



Could be. Just like the bible could be a fabrication of Satan to trick all people interested in supporting God to be sent to hell so he can torture them for all eternity.

ambassador_ahab: Each of those is an entire galaxy. And each galaxy has (to use scientific terms,) a shiatload of stars.

The concepts of distance, time, and size are mind-blowing anytime I see an image like that. I know that it all came from a big "bang" or "giant expansion" or however one wants to describe it. And I trust that physicists understand it as well as it can currently be understood. But I still can't wrap my brain around "what happened before that?" I know that all of that stuff was apparently packed into a space smaller than an atom.

So how did the tiny thing that expanded into our universe come into being? If there were previous universes/others, then when did that whole thing "start"? How was there "always something" and why?

Religious answers never satisfy me. Too simple and there's a whole lot of plot holes.

Or maybe it's like trying to explain the difference between blue and green to someone that was born blind...the concepts are too distant from my everyday life for me to comprehend.


Excuse me, but the term shiatload isn't the proper scientific unit. Modern science uses the SI unit metric shiatload.

dragonchild: Abe Vigoda's Ghost: A whole bunch of educated guesses take place on these things.

Not as much as you might think. There's no doubt there was a Big Bang. None. If you drew a graph that mapped the diffusion of the afterglow on a piece of letter-sized paper, the curve would be so smooth that the margin of error would be less than the width of the pencil's line. We know this because we have the data on the Big Bang's afterglow. There are few, if any, pieces of information in existence that are so precise. It's the scientific equivalent of nailing a three-point shot in Madison Square Garden. . . if you fired the basketball from Los Angeles. With, for good measure, a cannon shot from Dallas you'd need to aim perfectly to blow open a hole in the roof for the ball to pass through.

I'm talking about the Cosmic Microwave Background Radiation, of course, which XKCD turned into his "SCIENCE. It works, biatches" comic. You really don't want to question the CMBR findings as "a whole bunch of educated guesses" if you don't want to look like an epic idiot.


Dear Mythbusters...

Yes. And so do most scientists. That's why they test this stuff and not just take it on faith.
