As Webb rotates, it will have access to the entire sky!

The above video is a 'must see'! It reveals an absolutely fantastic piece of engineering and should answer your questions, Pete!
That's great, however there's as yet no telling how many see-through peep holes it will find. It seems the potential is large. I'm looking forward to that.
 
Yes, but because of the penetrating powers of the JWST, its images are likely to be less visually impressive than those from Hubble.

Much of the beauty of Hubble's images comes from the obscuring effects of dust which gives nebulae their striking three-dimensional appearance.

This dramatic effect will be somewhat lacking in the JWST images where the dust is more transparent to infrared.

anyone here ever time-align an 18-driver mono array? both physically and electronically? and how long did it take?

18 factorial seconds gets you out past 200 million years, what's the redshift of your patient, saintly, slow-to-break soul as the tyrannosaurs surf their Chicxulub wavelengths???

Very interesting article here from Quanta magazine and the nature of time. The difficulty has been in reconciling the generally understood smooth space time of Einstein that ‘flows’ with the randomness at the quantum level. It should be noted that Einstein never envisaged time as flowing, but saw it as locked in with space, hence ‘space-time’.

A Swiss physicist is proposing to bridge the chasm by considering the passage of space-time as creating information at the quantum level. So the future is unpredictable, but the instant it has passed, it becomes information (my very clumsy top level interpretation).

 
You mean it becomes history.

So I've got a hunch..bear with me here, I know it's tedious...could it be that the reason the universe is expanding is due to the ongoing explosions of stuff all over the place, causing more space to appear as a result and therefore simultaneously causing the universe's expansion to accelerate ever faster.?

my mind is a veritable hamster wheel

I have wondered aloud earlier in this forum whether entropy (energy changing) creates time. Since time and space can be considered the flip sides of the same coin (think about space-time), we perceive time being created as an expanding universe. This process would be relativistic and cumulative - hence from any point in the universe, it would appear that everything else would be moving away from you.

Nicolas Gislin is proposing that quantum uncertainty transforms into information which we perceived as information (history is what you called it - not a bad interpretation) and as smooth space-time. So the probalistic nature of the quantum view is united with smooth space-time and we then see time as ‘flowing’.

The only way this model makes sense at all is if everything is shrinking/decreasing in size exponentially as if everything in the universe is ever more approaching the singularity. How otherwise can coordinates relative to all objects not change though moving farther apart?

Reminds of a Leonard Cohen line in Stories of the Street.
