gamma ray blast spotted from 12.2 billion light years away

**brinox** · 02-21-2009, 01:23 PM

lightyears are indeed a measure of distance, but since you cant take a meter stick and measure the distance between such an event we have to rely on something that gives us a verifiable constant.

thus we can ascertain great distances when using the speed of light because of how far it travels. given the doppler effect coefficient(s) we are able to guesstimate how far away this event is. but its only a snapshot in time, at a later time it will have changed.

given the nature of using lightyears as a measure of distance comes with the added knowledge of the time it occurred. we are only seeing it now because the light took ~12 billion years to get to us. so in essence, its both how far away it was 12 billion years ago, in addition to it being 12 billion years old of data.

On earth you can calculate by measuring ground layers for example. I don't see how looking through a telescope gives you a valid measurement. Off course some Einstein dude has a big long answer to it, but I'm way to skeptical to be convinced.

Once you have a velocity of a galaxy and its acceleration rate you can "easily" go back in time.

It's not so hard as you might think.

So if we are still around in +1.75 billion years or so then we might get to see the Big Bang right?

I believe in science, but I don't believe there's an accurate way of predicting the age.

Go back to where? There will be no starting point for a reference. Also, there's just way to many variables in space to say that one galaxy has been at a constant rate of acceleration for x amount of years.

^^^ See... no disrespect, but the method of measureing stars distance and speed, time, place is well founded for decades. And just gets even more accurate by the year.

Whether you believe or not... well I can't change that. But I know it works and I know it can be cross proven from several ways.

To say you don't believe is too simple an answer.

betcha it was two good old boys drag racing their starships...that's just the glow from their con-fusion reactors

When they try to figure these things out, sure they can say, "this galaxy is traveling at xxxx mph", but how can you actually go back in time and trace that galaxy's path? It could've collided with several galaxies on it's journey and either sped up or slowed down, thus the speed is not constant nor consistent. And let's not forget about the effect of gravity from neighbouring galaxies. I believe the universe is billions of years old, but how old, that's anyones' guess.

Perhaps if I was a scientist, I could try to explain this "theory" in some sort of scientific way, but I'm no rocket scientist!

Of course that there's too many variables. But *if* you ignore them, or only apply the significant ones, you can come up with a reasonable estimate of creation.

Depending on how accurate you want to be, you can also assume that a galaxy has been receding for most of its age, given that just after the big bang the universe was rapidly expanding.

And if it did collide, we'd see the effects of it...

How old is a guess to the nearest billion. We know the science of radiation now for a long time. We know how cool the background radiation is and we know how long it has taken to get that cold. Gravitational effect of other galaxies? Sure thats easy. If you can see a galaxy, you can see the other that might have a grav. effect on it. They won't be THAT far apart.

If the theory works out right its not possible fore galaxies to collide....

Have we even found that point? For me, I'd like the accuracy to be within 2 billion years, give or take a billion!

But we know galaxies do collide.

Gallaxies do collide. And it works for the theory.

There was no original point, that is a common misconception about the big bang.

thanks for the link about the galaxies colliding, I forgot to consider supermassive gravitational attraction when I was thinking about it

I think these scientists just make this

up

They throw a

load of astronomical equations out there which too most is just like "Oh yeah for sure i get it", and hope no one comes along and

s on their theory which usually does become the case weather it be tomorrow or 100 years from now, they go what the hell were you thinking this is what it means then another 100 years later the same crap again... Lets just say , it was really far away a long time ago , I'd be more ept to buy that than 12.2 billion light years and all the other bull they throw out there.. Just my 2 cents but hey who am I...

Yaaa. Those pesky scientists. They should be out on the farm shovellin' for their bread... none of this space shenanigans!

The point at which the big bang occurred. If it's even possible to know where.

haaaaa ha haaaaaa lmao..... this thread is propper funny....

i love anything to do with space.... its just intriguing....

anyone with the slightest amount of interest should watch
http://www.youtube.com/watch?v=3TlfZ...eature=related

also....

Scientists have created a gigantic machine to recreate the Big Bang which created time and space more than 14bn years ago

The Large Hadron Collider(how much fun would you have with one of these

) - based at Europe's particle physics laboratory in Switzerland - will attempt, for the first time, to discover the particles at the very heart of the atom.

Experts hope that could lead to all sorts of other revelations - from the existence of dark matter to new dimensions.
