Limitless space?

Question

1)If i look into space, because space is so vast that the light that comes from the distances described then we're in a time bubble where everything we look at in space has already happened and is only a measure of how long ago.

So that being said

how deep into the time line can we look 9/10 th from now till the beginning?

Answer 1

The Universe became transparent to photons about 400,000 years after the Big Bang, which was 13.7 billion years ago.  Looking back that far shows a uniform glow (at radio wavelengths), the Cosmic Microwave Background.  So the fraction of the time we can look back is:

(13,700,000,000 - 400,000) / 13,700,000,000

or 99.997% of the way back to the Big Bang.

In principle, we could look back further using gravitational radiation, or neutrinos, but this has not been done.  Some experiments to indirectly detect the results of gravitational radiation from the very early Universe are currently in progress, but they are quite difficult and may or may not succeed.
