Things We’ve Never Seen: The James Webb Space Telescope Explores the Cosmos

#BrianGreene #NASA #JWST #UnfoldTheUniverse
The powerful James Webb Space Telescope--the successor to the Hubble Space Telescope--promises insight into profound questions that have dogged philosophers and astronomers for millennia. What is the origin of the universe? How are stars and planets created? Is there life elsewhere in the universe? Brian Greene brings together four scientists who will use the Webb to investigate these very questions: John C. Mather, NASA’s lead scientist on the project and a Nobel Laureate; Natalie Batalha, NASA’s lead scientist on the Kepler Mission, which discovered the first rocky planets outside our solar system; Adam Riess, who earned a Nobel Prize for his revelations about the expansion rate of the universe; and Ewine van Dishoeck, a Kavli Laureate for her pioneering work in the field of astrochemistry.

This program is part of the Big Ideas series, supported by the John Templeton Foundation.

Participants:
- John C. Mather
- Natalie Batalha
- Adam Riess
- Ewine van Dishoeck

Moderator:
Brian Greene

We are so fortunate in this day and age to be able to have access to such incredible knowledge and information presented by some of the worlds foremost scientist and thinkers. People like Brian Green, Sean Carroll, Neil deGrasse Tyson, and Richard Dawkins to name a very few. Never before has such a wealth of knowledge been available to so many. It is sad how much of this incredible internet technology is wasted providing useless empty calories of popular drivel. I am so grateful for the rich and valuable content .

Cannot get enough of this topic

I fall asleep every night listening to WSF

This is a dream come true

[rustyshackleford]

Good luck humanity, we so need this.
Glad WSF is still going strong.

Brian Greene DID an excellent job in moderating this

[amosikyan]

The triumph of collaborative intelligence of humanity. That’s a noble cause to spend resources on. The way to go and salute to all curious minds!

[abdulmateenroonjho]

I wish in future I'll be part of such great mission,
Love and respect from Pakistan 🇵🇰

[kasozivincent]

Wow, I love listening to people at the frontier of human knowledge. This was super cool

[kenadams]

This telscopes Gold plating was formed in a dying Star's explosion maybe billions of years ago.Asteroids etc bring it to earth and we mine it for use on this marvel of human ingenuity. Perhaps the areas the telescope goes to, or sees, will be the same places or events the original Star lived.

Great job from the team to get this complex and expensive bit of hardware into its operating position. A lot could have gone wrong, that it didn't is a great credit to all involved.

Now for the exploration and science.

[mbabcock]

Hundreds of millions to pay, thousands to build, hundreds to process, dozens to interpret, several to discover and billions to benefit.

The World Science Festivals is a most informative and professionally done science YouTube channel out there with Brian Greene commentary at art level. Thank you so much for letting me learn through listening and wish all the best to that mission and scientists behind it. 🤞.

[ronaldbass]

Awesome program. I feel blessed to have witnessed this program and I'm inspired to see that the problems we think of as so vital today. Have already been considered and eclipsed by the cutting edge of the world of science today. May you all fly high and sail far. Amen and so be it.

[fabersoul]

always a wonderful treat on a dull day. thank you Brian Greene

28:00 has a great new telescope with 100x the power of Hubble, that can literally look at and analyze distant atmospheres with incredible accuracy. Talks about finding terrestrial planets and signs of biology.
Asks quiet careful questions about _"maybe at some point there may be a potential claim that perhaps a distant possibility may reside in that planet having oxygen, perhaps at some point plausibly although improbably having been perhaps maybe created at some point by life?"_
So overly cautious and terrified to even ask a serious question, due to the giggle factor, even today in 2021..

Yet not a SINGLE MENTION of technosignatures in the atmosphere.

Not a single mention of the fact that, finding industrial pollutants in an exoplanets atmosphere, wouldnt be _"maybe possible at some point perhaps could potentially be...", _ but would be 100% undeniable evidence of an actual civilization either existing there now, or having existed in the past.
Why? Why are mainstream scientists (with one exception, Avi Loeb) so excessively careful when speaking about finding life? You all THINK you want to find evidence of life, but in reality you cannot even ask the right questions that would give a DEFINITIVE answer, you can ONLY ask questions that would give a vague "maybe", because you're subconciously utterly terrified of finding life for real, not just in theory..

It's 2021... Is it not about time we stop act like scared children, and start acting as adults?
Ask the important questions, do the important science, that leads to REAL conclusive evidence.
Why are you all ONLY comfortable asking about methods that provide evidence that always has a caveat, always a "get out of jail free card" for life? _"Oh even if we discover oxygen on another planet, it MAY not have been made by life, it COULD have been formed by natural processes..."_

It's just the same old over and over and over again.
Enough. Can we please focus on searching for the signatures that WILL undeniably without question prove life or not?
Can we stop being so excessively insanely cautious? Isn't science about doing science wherever it leads?
It's certainly not about AVOIDING to look, because you're secretly terrified you might find something?
The only things you wanna talk about and look for, are things that can be explained away as not being caused by life.

Why else was there ZERO mention of looking for technosignatures in this entire presentation?
Because its so improbable? Why is it improbable? There are hundreds of billions of planets in our own galaxy, and we human beings exist right now sitting here. There's nothing improbable about it. Ask, investigate, stop being scared.
Boggles the mind.

In a nutshell….the universe is so complex that it is a miracle that we are here…🤣

[saketsinghkaurav]

It was a masterpiece event on JWST and listening Dr John, Dr. Natalie, Dr. Ewine and Dr Adam in the well-orchestrated interaction by non-other than Dr. Brian Greene. Brian, you made this event so special with your excellent questions and the way you put them before the experts so that anyone who is interested can not only understand the very subject matter of the discussion but also enjoy every moment of such incredible discussions. You and the team of the World Science Festival are doing great work in communicating science with so ease and full of enthusiasm using full of technology. Keep it Up. And Best of Luck to all the team of JWST for its tomorrow's launch.

I’m so grateful to be alive during this nexus point in our evolution… I feel like we’re witnessing a pívot point where our collective brainpower can unlock new revelations into the natures of our existence

This video is better planned and produced than what NASA itself did with their L-30 briefing videos on JWST. I’ve watched a lot of interviews of these scientists in different videos on different channels. This video shows why hosts and their questions matter. It was smooth, and his questions were somewhat intellectually stimulating, not just repeated questions that these scientists have been asked many times the past few months now.

As a kid i was fascinated by the race for the moon and as an 8 yo i watched the landing - to have been allowed to live from that to this era with all the progress humanity made is an honour beyond words

Yes, the screen and keys are slightly blurry ( of joy & gratitude ) as i type this

Webb will prove that black holes are just FANTASIES, like big bang or finite universe. Also red shift does not show EXPANSION, it shows DISTANCE, since the red shift is due to BOTH speed and shielding of photons by a matter on the way (also spatial spreading of the beam of light) where shielding is much slower than during intensity drop (to understand this you must understand what LIGHT is and what is its FREQUENCY..it is just a simple sand thrown to some direction where each sand grain correspond to one photon and the frequency is just an impact of those photons (sand particles) that travels exactly or almost exactly in the same line (it should arrive on/hit the same detector area)). And the BACKGROUND RADIATION shows only the DENSITY of the infinite universe which is almost constant throughout the visible universe
