The James Webb Space Telescope can see real things back in time, as if one is travelling by a time machine. But it CAN'T see time.
My primitive idea of the Big Bang model drawn in the image beside, it was posted in Facebook five years ago on 27th December, 2016. Though, my entire idea has been enhanced and there are considerable differences now than my ideas as reflected in the image exactly five years ago, It's about the Big Bang, Inflation, expansion, early galaxies and those galaxies now. Since the inflation caused rapid expansion of the space much faster than the speed of light, the primitive galaxies then in the early universe too receded faster than the speed of light from their earlier locations to their current locations in the present Universe.
The light those radiated from the primitive galaxies became so slow; so that they have gone late and some of them are reaching us now - long after they were radiated.
Therefore, the James Webb Space Telescope can see them now, after so many billion years from their first radiation form those primitive galaxies.
However, this image may assist a novice person to visualise how the James Webb Space Telescope is going to see the earlier Universe, as it was soon after during the time of the Big Bang. One has to visualise the early universe as the small white balloon in the image and the present universe in sky balloon, both in common axis of time, the same galaxies are there on both of the surfaces of said balloons.
