Will We Ever Witness The Birth Of The Universe ?
« on: 29/07/2007 18:53:26 »
Hullo,

The Universe is well old isn't it?..It's the oldest thing ever !!.....it's even older than some cheese I found in the back of my fridge !

Do you think that with advances in all the differing types of telescope technology that we will ever be able to see as far back as the the birth of the universe ?...perhaps this is how we'll eventually find out what really happened ?

whajafink ?

Firstly, it is even speculation that the universe ever had a birth.  The current preferred theory is the Big Bang, but there is no proof that there ever was a Big Bang, or did the universe exist forever (maybe with changes of phases over time)?

Secondly, what do you mean by 'see'?  We will never be simply be able to look up at the sky and say 'Hey, it looks like I can see a Big Bang there'.  The question is more as to whether we will find forensic evidence that scientists will decide is a remnant of the Big Bang (the closest we have is the cosmic microwave background radiation, which is considered to be forensic evidence to a time 380,000 years after the Big Bang - but like all forensic evidence, it is subject to reinterpretation).

THANK YOU GEORGE (George is good, george is great...george knows stuff)

If we can 'see ' far back then perhaps we'll be able to determine if there was a big bang or not.

Ok then....if there is ambiguity in the term 'see '.....do you think that the secrets of the universe will ever be revealed to us ?....and will those secrets just lead to more questions ?....in fact...could it be that there is just a ' never ending ' situation here when it comes to the nature of the Universe ?

Although we will never get any infomation from the first time of the 'big bang' via electro magnetic radiation due to the lack of transparency of the earliest times is there not a chance that when the technology is developed gravity waves might yield some answers?

I believe in your last bit:

"could it be that there is just a ' never ending ' situation here when it comes to the nature of the Universe ?"

In that I think the Universe just cycles over time from a state that is cool with mass and gravity to a Plasma state, hot with no mass or gravity. It is always in existence but cyclic.

I have difficulty with the CMBR idea even though it lead to a Nobel prize.

@ syhprum

I think gravity waves will reveal all!

That'd make global warming look a bit tame!

Gravity waves could not exist until we had some inhomogeneousity within the universe.  Even then, early gravity waves would be so stretched out over the present wavelength that I would think it unlikely to be able to measure them with earthbound instruments, although they may be apparent in the movement of large regions of the universe (maybe in the movement of galaxy clusters, or even larger structures).
