How is it we can see an object 13billion light years away, but the universe?

Question

is supposedly only bout 4 billion yrs old?

Answer 1

It's the Earth and this solar system that are 4-5 billion years old.

The universe is 14-15 billion years old.

Answer 2

OOOPS...small error. The Universe is reported by scientists to be `13.7 Billion Years Old, but the Earth is dated at between 4 and 5 Billion Years old.

Now we can see objects as far away as 40 Billion Light Years distant using our most sophisticated optical and radio telescope equipment.

Getting a handle on distances is tough I admit... However, if you are moving away from something at a high rate of speed, and it is "also moving away from you" at a high rate of speed, the distances become very huge over an extended time (like in five or ten billion years).

So, it is not unexpected to locate objects 20, 30, or 40 Billion Light Years away from us.

Answer 3

The Solar System is 4 billion years old, the universe is more like 15 billion.

Answer 4

It would stand to reason that if a scientist speculates that the universe is a certain age, that that scientist is only speculating to the best of his knowledge.
If you read speculation, then you also posess the ability to read beyond the theory.
No one knows how old the universe is, and in fact, there are things right here on this very planet that scientists cannot fully explain. Did you think that was the case?
The universe could very well be infinitessimally ancient. How could anyone date it?
We have come close to dating the solar system and our Milky-Way Galaxy via various research, but the universe?
Good luck with that. Not yet. Some things are beyond our current abilities to comprehend, and much less to exactly quantify by even a miniscule fraction of fact.
The better method of figuring these things is to be the scientist you already are, and to think for yourself. Ask these questions alone. Think for yourself. The brilliant folks are working on it, and I really love it, and I admire and respect their work, but let's keep our own minds open for our own discoveries for the time.
The answers come much more easily when we relax, and try not to overthink the issues.
Being smart doesn't always mean being right.

Answer 5

xc It's nonsense, what you have heard. About 13 to 14 billion ly is the furthest distance we have ever spotted an object (on hubble's famous deep field picture). The universe itself is assumed to be about 1 or 2 billion years older than this, so to speak, about 15 billion years. But that is just pure assupmtion, just one of many theories, no more. We do not really know, that is why it is better to speak of the so called "visible universe".
Who knows, if we develop an instrument 100 times as strong in resolution as hubble ... who knows what we might be able to see then ....
btw the earth is about 4.5 billion years old, may be you got the number from there ...

Answer 6

The universe extends 6 billion light years from where we are.
The universe is a finite entity so it must have a maximum size,this doesn't mean that the universe couldn't be much older.
90% of the galaxies observed by the hubble deep field survey do not exist to-day.
Many of the galaxies we see to-day didn't exist when their light reached us.

Answer 7

Our Solar system is only 4 billion years old.

We can't actually SEE thing 13 billion out, we sense them with equipment. Radio telescopes and such.

Answer 8

I have crazy answer the light of our sun when it travailing for infinitive distance it is retain back for us and that let us said we can see our splits light again it is crazy idea but possible because light goes similar carve.

Answer 9

Don't know how old Bud Lightyear is.
