I think would pretty hard if you can't see both sides of it to determine the age over all. some say 13.7 billion years and others vary

True some say the universe was created 8,000 years ago in the forum we see today. I don't know when or how it came about. The accepted popular theory is the Universe is 13.7 billion years old and was created from a minute singularity. The same popular theory also says some objects in the Universe are farther than 27.4 billion light years apart. Ergo at some point in "time" they had to travel faster than the speed of light.

Let me do the math; 13.7 + 13.7 = 27.4.

Oh No Julie keep it up, your perfectly great.

R U hitting on Julie?

On the contrary she is way above my league and she is way smarter than I am.

OK but any comments on my math?

This is beyond me but here is a link if you can follow the math. It's a bit more complicated than 13.7 + 13.7

The speed of light rule only applies to objects with mass as they move through space. Its not the objects themselves that are moving at the speed of light, the the distance between them that is expanding at faster than the speed of light. The fabric of space-time does not have to follow the rule postulated by Einstein's theory of special relativity.

fixed! ty.

Welcome to the Forums Caleb! your screen name reminds me of a movie I saw, with Nicolas Cage, about a time capsule from the past, his son's name was Caleb! Haven't looked at your link btw:)

[edit] No maths for me, gets me cranky...

Its not the objects themselves that are moving at the speed of light, it is the distance between them that is expanding at faster than the speed of light

By that I assume you mean Objects A and B each traveling a 0.75 the speed of light away from each other, will have the distance between them increasing at 1.5 X light speed.

So does this mean one is red shift and the other blue?
better pick up a six pack before leaving :))

Then neither would see each other by rights. Only at the beginning.

By my math if both object were moving away from each other at the speed of light at some point they had to travel faster than light.

New math; starting as a singularity two objects move away from each other at the speed of light for 13.7 billion years, double the speed of light away only from each other yet they are more than 24.7 billion light years apart. 13.7 x 2 = 24.7 not 98 as is observed. Numbers not exact but close enough for this question.

Then neither would see each other by rights. Only at the beginning.

All objects have slowed considerably. I'm wondering how in the past things went faster than light.

Actually I'm under the impression that the Universe is accelerating it's expansion.

Q. Did the Universe start with a singularity?

Q. How old is the Universe?

Q. What is the distance between the two farthest points in the known Universe?

We all know the Universe is 13.7 billion years old. The distance from the big bang till here is 13.7 billion lightyears, if the Universe started with a big bang that is and as only spacetime exists in the Universe. With the last question I've added I'm wondering, if the Universe started with a big bang, would the singularity be the center of the Universe? In that case the answer to question 3 could be 27.4 billion lightyears.

Q. What is the distance between the two farthest points in the known Universe?

As above, 93 billion light years.

Oops, didn't take the expansion into account:(

If that were truly the answer, that would be great but it's much too simple...

Apparently not Centre

So what the article says is that everyone and everything is the center of the Universe, interesting...

Cheers everybody

So - being in the middle (as I am :)) with everything revolving around ME (SNORT - warning; spell of megalomania approaching :)) makes it so much harder to see everything around the edges :)

Could that mean we only think the universe is as old as it is (approximately 13.7 billion years) because the light from most if not all of the "missing matter" simply hasn't reached us yet?

Must go now - have a world to rule :)

The age of the universe was first worked out by calculating the rate of expansion and extrapolating back in time to how long ago everything was all in the same spot.

One needs a bit of peripheral vision you see Annie.

we can estimate the age of the universe to about 0.4%: 13.77 ± 0.059 billion years

Age

AS Julie says, the estimate fis rom extrapolating back from what we observe. Don't get confused between that and the SIZE of the universe which has constantly been expanding since the big bang.

BTW I usually find that a piece of plastic 12" long helps as a rule.

We can't define the size of the Universe, because it's expanding! Good point Chris!

Hang on a minute! Are you all saying things are different from the middle of your universes? :) I think I need a lie down now... :)

*weakly - from chaise longue* but what if there was a lot of matter around the bit that went boom... when it went boom and expanded into what we can see... propelling or pushing everything else outwards so that we can't see it... yet... till it's light reaches us? :)

edit: I'm not sure that question made sense once it left my head...
