Unknown: Cosmic Time Machine

"Light in A Dark Time", a quote from a female astrophysicist on the show, is the best way to describe the James Webb telescope. The short documentary is definitely worth watching as it showcases the difficulty in designing, leading, getting funding, the disappointments and all hurdles that had to be overcome to be able to have the very risky and near impossible successful launch. Now that it is launched, humanity can see back in time 13 1/2 billion years ago, and the first image shared showed a massive amount of galaxies that old. I didn't give it a 10 star rating because quite honestly, if you are not an astrophysicist, and just a normal average citizen, it is extremely hard to wrap your mind around it (the shear time and distance of it) and hard to actually understand how truly awesome it is. Even by the awe on the astrophysicist's faces who do understand the meaning the Time Machine concept and distance, it is so amazing for them to comprehend it all as well at first look. Am sure it is just a first look at what is to come with more discoveries as scientists study the images.

In over an hour there's barely 5 mins of actual content that directly relate to the Webb telescope itself.

There is so so much of unnecessary nonsensical fillers it's just ridiculous!

Unknown alright. Viewers still know almost next to nothing about the Webb telescope, nothing more than a cutesy science phamlet for 8 yr olds at the school exhibition.

Even solo contributors have put out much much better YouTube content about the Webb telescope.

Scenes of people jogging, family photos, nobodies (to the viewers) talking about their 'feelings'??? Huh????

Giving it 2/10 makes me 'feel' so so generous. 🙄

This isn't about the wonderful discoveries that JWST have delivered but instead the brilliant scientists and engineers who delivered the JWST. Stories of unsung heroes, many of whom have dedicated over 30 years of their lives to pull off the near impossible. In a world that is ever increasing reliant on technology but equally contaminated by people who disrespect expertise, this is a much needed reminder that we owe a great debt to people who not only know their stuff but who also put in the hard, gruelling yards to deliver. If you want to explore what JWST has done for cosmology, I thoroughly recommend Brian Greene's recent World Science Festival interviews.

Half of it was interesting science and tech and beautiful imagery, the other half feelgoody blather about personal details and mini-bios of people involved.

The early development and various designs was glossed over by a guy petting his dog going through wrinkled papers on the dining-room table. Should have been more about why it uses infrared light and red-shifting of distant galaxies, why the Arianespace base in in south america. And so on.

The worst parts were the segments with the airheaded valley girl types on the phone screens jumping up and down saying "Ohmygod" "yay" etc. Gag me.........

So much potential here. They could have used this documentary as an opportunity to educate the public about the amazing science behind JWST, instead they focused most of the documentary on forced drama as if it were another brainless reality TV show. Topics they could have covered to better illustrate and educate the magic:

What is red shifting and tangible explanations on why the JWST is needed over the Hubble.

The groundbreaking use of beryllium for the mirrors and why the element was selected for its unusual properties at cryogenic temperatures.

The cryo coolers and how their novel design allows it to cool the instruments down to near absolute zero.

The damaged mirror and how the JWST is able to overcome it.

The unusual approach of physically deforming the mirror to focus the image.

Etc etc.... Could have been great but instead they took a story about one of the greatest scientific achievements in human history and chose to dumb it down to nearly worthless drivel.
