Short (6m33sec) video describing what cosmologists think the very early universe was like and how the Webb will let them see it.
I expect the Webb telescope will reveal surprises.
I agree. I can’t wait to hear a scientist say “We were totally wrong about this”
(theory or that theory)
It’s getting closer to that first picture- it’s gonna be exciting!
There’s nothing like the universe to bring you down to earth!
We haven’t found the middle or the edges yet. Good chance we never will.
We stand at the edge of the universe every second.

I can see for light years and light years and light years and light years and light years
oh Yeah
Good video.
I expect'jaw-dropping' suprises.
They're scheduled to show the first images on July 12.
I am sick to death of these never ending youtubes about what the Webb is supposedly going to see. Everyone with a clickbait headline. Wake me up when they actually have some pictures.
Yeah, cool seeing distant stuff for the first “time”, but not “ in the past”.
Folks really do understand that we won’t be looking “ back in time”, just “in the distance”, right?
God has you fooled otherwise.
You won't see anything you're not supposed to see. NASA data and imagery is encrypted and classified. Whatever imagery or data they release has been through a sanitization/declassification process.
The reason we never went back to the Moon is not because we forgot how.
Considering the speed of light, the light we are seeing is very old.
It takes a year for a light to travel a light year.
Uh huh.
Agreed. But we are looking back in time, just at light emitted by an object far away.
A review of how the speed of light is derived is an interesting convention. An agreed upon working solution. In fact, some learned folks actually admit that the speed of light and an image are not very closely related.
Working science, not absolute science. Pretty standard.

Check this out. It’s worth 20 minute
Here’s the link. I think...

The Apollo program ended early, because the American public’s attention span petered out, and we didn’t want to spend any more money.
How dare we show the merits of Capitalism.

If the engineering folks didn’t have a pretty good idea what the speed of light is, radar would never work.
c = fl
where f is frequency, l is wavelength, and c is a constant. For electromagnetic radiation, c is the speed of light. About as absolute as anything can be, this side of Divine Perfection.
And visible light occupies only a tiny fraction of the electromagnetic spectrum.
The spectrum includes radio, radar, infrared, visible light, ultraviolet, X rays, cosmic rays (named in order of steadily increasing frequency).
