Lo desconocido: La máquina del tiempo cósmica

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.........

This was the first of the Unknown documentaries that I watched. I chose this one as first because the subject is what interested me the most. We all are curious about the origins, about how everything started. Most likely questions that will never been answered, maybe partially, and that will be because of the James Webb telescope, an unbelievable human achievement. The documentary is well made, consisting of interviews of several people that were involved in launching the telescope. I get it that people that worked on this project for decades are getting emotional. The huge amount of money, the time spent, everything that could go wrong, it's all very stressful for those people. I would have liked more of those stunning space images. The ones they showed I've already seen them before, like most people I guess, so it would have been nice to show us some more images that were never released before. But other than that the documentary is informative and that's what its all about. A good watch if you're interested in space.

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.

As "Unknown: Cosmic Time Machine" (2023 release; 64 min.) opens, it is "13.8 Billion Years Ago" as the voice-over reminds us that is when the Big Bang occurred. We then go to "December 25, 2021" and the countdown for the launch of the James Web Space Telescope is on... Just before takeoff, we go back i1990 when the Hubble Space Telescope launched. At this point we are less than 10 minutes into the documentary.

Couple of comments: this documentary does a great job explaining some of te background as to what it is the James Webb Space Telescope actually does which its predecessor didn't do. Much attention is given to the 344 "single-point failures" which the 10,000 men and women who worked on the Webb for several decades, must avoid, an almost Herculean challenge. The big pay-off comes in the last 10-15 minutes when we get the spectacular photos which the Webb is now collecting, along with a treasure-trove of related data. One of the photo's shows a galaxy "being born" 13.2 billion years ago (yes, not all that long after the big bang). It also made me think how planet Earth has been fundamentally ravaged with in just the last 250 years or so (since the Industrial Revolution). This does not bode well for the future of humankind...Meanwhile, enjoy this every entertaining AND educational documentary. Can be viewed by anyone from ages 7 to 77.

"Unknown: Cosmic Time Machine" started streaming on Netflix a few days ago. If you have any interest in space or in human explorations, I'd readily suggest you check this out, and draw your own conclusion.

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.
