How can the Hubble Space Telescope look back in time?
It can look back in time in the sense that light from stars can take many millions of years to reach us but to suggest that Hubble can see the first moments after the big bang is total garbage. It is rubbish invented by astronomers to justify to the public the vast sums of money invested in their science. If we are to believe Einstein nothing can travel faster than light so we cannot be in a position where light from the Big Bang is catching us up.
