Explorando o Desconhecido: A Máquina do Tempo Cósmica

What an inspiration to us all the accomplishment that can be made when everyone has one goal! The pictures are absolutely beautiful and the thought and visuals of what is really out there is amazing. Without us seeing behind the scenes and all the work that went into it we would just take it for granted. Thank goodness for this film for showing us all what we really don't know behind the scenes. We just get to see the pictures from online but this film was detailed in showing us the hardworking people and the nervousness that goes into everything before the rest of us gets to see it.

There was only one character/astrophysicist that was really. Too much gibberish for me I fast forward her parts. I want to know the educational and the story and people behind the scenes.

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.

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.

Why do women always begin something by saying 'when I was a little girl.....'? Or something about "me"? The personal stories of people involved in James webb are irrelevant. Maybe a few seconds would be enough, and not tens of minutes. The James Webb project was the reason to watch the show. While the telescope did end up extremely exciting and it's changing our views about the age of the universe and possibly the Big Bang theory, the show is quite boring and slow. While the woman scientist (or engineer?) was focused on herself and her emotions and experiences on the projects, the guys talked mostly about the project.

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.
