How deep can Hubble Telescope see??
-I understand that the Hubble telescope can only resolve galaxies at about 13 billion years old, using gravitational lensing. I am curious, is this because the telescope does not have the power to see farther? Or is this because there are no farther galaxies to see because this is too close to the Big Bang? Or, is it perhaps because the redishifts become so great that galaxies disapear at this point? I ask because I am curious to know if the James Webb telescope will actually provide new insight and perhaps even observations of older galaxies. Thanks!
P.S. - About my last point. At what age does the redshift become so shifted that galaxies no longer are observable (even if this boundary is older than the universe in theory, I am curious to know what it would be)
