Hubble telescope
 

I am in the process of watching the Science Channel about the Hubble and just amazed at the pictures the telscope has taken..I mean they say they can finally date the universe cause of the telescope.It's just amazing at waht man can do with technology...

Re: Hubble telescope
 

There are galaxies in the Hubble's "Deep View" pictures that are exist only 600 million years after the Big Bang. It is incredible to watch how Galaxies change the further back in time you go.

Re: Hubble telescope
 

I mean when does it end or does it even end.It can see so far away...

Re: Hubble telescope
 

Hubble is awesome! Where it ends is a facinating question.

Think about this. How small is small? When does small end? After discovering the atom, it's like another universe. How can we measure to the point when there is nothing, or is something smaller found again, and again....

Re: Hubble telescope
 

It's all made up. That there scope can't see nuthin. The earth is only 6,000 years old I don't care what them people see!!:toofunny

LOL

Re: Hubble telescope
 

:lol

Re: Hubble telescope
 

Probably the same bunch that said they went to the moon! The telescope is probably trained on the back yard in Hollywood! Can't trust nobody, no more! :ursofunny

Era of 1 Planck Time

In the era around one Planck time, 10-43 seconds (after the Big Bang), it is projected by present modeling of the fundamental forces that the gravity force begins to differentiate from the other three forces. This is the first of the spontaneous symmetry breaks which lead to the four observed types of interactions in the present universe.

Looking backward, the general idea is that back beyond 1 Planck time we can make no meaningful observations within the framework of classical gravitation. One way to approach the formulation of the Planck time is presented by Hsu. One of the characteristics of a black hole is that there is an event horizon beyond which we can obtain no information - scales smaller than that are hidden from the outside world. For a given enclosed mass, this limit is on the order of

where G is the gravitational constant and c is the speed of light. But from the uncertainty principle and the DeBroglie wavelength, we can infer that the smallest scale at which we could locate the event horizon would be the Compton wavelength.

Question
What is Planck length? What is Planck time?

Answer
The Planck length is the scale at which classical ideas about gravity and space-time cease to be valid, and quantum effects dominate. This is the ‘quantum of length’, the smallest measurement of length with any meaning.

And roughly equal to 1.6 x 10-35 m or about 10-20 times the size of a proton.

The Planck time is the time it would take a photon travelling at the speed of light to across a distance equal to the Planck length. This is the ‘quantum of time’, the smallest measurement of time that has any meaning, and is equal to 10-43 seconds. No smaller division of time has any meaning. With in the framework of the laws of physics as we understand them today, we can say only that the universe came into existence when it already had an age of 10-43 seconds.
