Does this mean that if the hubble were more powerful that it would be able to see the beginning of the solar system?

Yes.

its got something to do with the speed of of light and the light from the stars that we see on earth is really light sent from that star hundreds or thousands of years ago depending on the stars distance

since the universe is infinently large there is light beams being sent in our direction from billions of years ago if the hubble were more powerful it would be able to meet this light half way making giving us the ability to see into the past

if im wrong or someone has a better way explaining it speak up

I am not an expert or anything, but i think i could explain, and chance being totally wrong.

The diagram would make more sense if it was curved the other way, you see, if the big bang was one point, it expands in a sphere shape.  The first group of matter propelled would be our solar systems, then the different layers going to the big bang are groupings of other matter that was behind ours.....

so it\'s like... if a stone makes ripples in a pond, and you look back from the outer ring at the smaller ones coming out after you...

i think. probley way off, but i gave it a try.

Actually no, even if they made a better Hubble it would not be able to see the beginning of the universe, the light would have degraded into Microwaves, they launched some probe that\'s designed to pick them up so they can see further than Hubble.

Which rays would turn to microwaves and what about the probe makes us not be able to see that far if thats what its designed to do.

I would assume that by increasing the power there would be some way to see certain events that have happened before but i dont know if its even possible to look as far back as the beggining. The amount of light years seems too immense for us to achive at this point

This guy never thought about light polution. Nobody in big cities could see them.

I swear if that happens I\'m so leaving this planet.

The further you look, the further back in time the origin of the energy you are seeing.  Ie, looking at a star 1000 light years away is energy that left that system 1000 years ago, 10000 light years away 10000 years ago etc.

Theoretically, if you had a telescope that could look FAR enough, you would be seeing energy that left so far in the past that it\'s from the origins of the universe.

Practically:
there is to much dust and ambient energy in space to ever see that far.
The radiation era near the begining of the universe would create a distance which we wouldn\'t be able to see past.
Even if we could, this relys on the "faster than light" early miliseconds of expansion of the universe to be able to see light from our own origins (which wouldn\'t be our solar system or anything, but rather the cloud of matter which would later form the milky way.

We\'ve pretty much reached the limits of the optical spectrum with current telescopes (there really is a lot of dust in space when you are talking about looking through millions of light years).  The other spectrums that we can use to look further have their own limits, which we\'ve either reached or we have defined.  We\'ll never be able to "see" back that far.
