The New Golden Age of Space Exploration

It is quite full of ignorant prejudice of Zurbuchen to think that advanced civilizations would have settlements on multiple planets. It means that he's ignorant about the macro-ethical reasons for why that'd be avoided by any civilization.

Its so powerful and true that a large quantity of what we were thought is wrong

Thank you for this ❤ team outterspace

Great talk, Brian! I have a question - Hayabusa2 found 20,000 organic molecules which is basically a VERY TINY number. For reference Avogadro number is 6.023*10^23 so 2*10^4 is a very small number. How are we then so sure that it is from a primordial asteroid and not leakage from earth's atmosphere or some earth-origin dust particle. Even an entropic argument seems to be in favor of a leakage into the sample collector (there could be innumerable ways of leaking such a minuscule number of molecules).

How do we definitively know that the sample is 100.00% from that asteroid.

Great to see live WSF meeting.

Absolutely loved this episode. I'm a regular watcher and this one is the best of the year. Thank you Brian for producing this programmes. As a non-scientist, I find watching your programmes one of the best ways to glimpse into the fields of physics and cosmology!

The cost of rocket production has gone down 1/3 because it is now non-union, low benefit, private sector employment working for stock options rather than benefits. It has little to do with 24 hr shift work. Come on Mr. Zurbuchen. Not to turn the conversation into a labor dispute, but it may be greed or the motivation for wealth that drives down costs at the front end. There has been a cultural shift in that regard since the early space program. How do scientists negotiate that phenomenon?

Dumb assumption, that Alien life works like ours and needs the same habitable zone, Alien life may not even need chemistry to work, just magnetics or energy, DUMB ASSUMPTION, NARROW MINDS

I think he should have said "Astronauts should be less like overpaid footballers."

These are so good talks!!!!!! Love them. Great moderation as always by Brian Greene.

Space exploration? More like UNIVERSE DOMINATION and that's a FACT!

In this era of robotic and ai systems filling less desirable jobs, we need to explore just for job creation.

Another benefit, Steven Hawking says some disaster will make humans on earth extinct, other estimates less then 1 million, or as soon as 500 million years.

With the technology we learn from habitating Mars, will be needed here in earth with in this 1000 year to 500 million years and before earth becomes hazardous to life.

Being prepared to create sustainable life should be the first concern, and we learn that by taking Mars.

If it wasn’t for science… we would not have the things we have today.

That life will be found on other planets, or moons in our galaxy is a given. The bigger question will be the origin of it. The Chicxulub asteroid killed off the dinosaurs when it hit the Yucatán Peninsula 66 million years ago. 25 trillion tons of material (50,000 cubic miles) were ejected from the crater, some of it left the earth's orbit. Some organisms can survive in space. Over 250 different species of bacteria and fungi can survive, and thrive in outer space The ejected material would have spread through our galaxy like a cloud, and it could have ended up on all the celestial bodies where it could have reproduced. So......yes life forms will be found in our galaxy, but the odds are that it was probably transported from earth 66million years ago.

What about hydrogen from the sun mixing with oxygen in our atmosphere to create our water, star water.

great... bravoo

🥲 this made me so HAPPY! 🤓🥳NERDS RULE 🤘🏼😎

"Duck & Cover" people are STUPID.!😂😮😢

imo the first question would be something like have you seen the princess bride?

This is like watching an alternate reality to the tv show FOR ALL MANKIND. Aside from that random observation, this conversation is an interesting juxtaposition against the UAP Whistleblower UAP Congressional Hearings. Thanks for sharing.

70 years from Wright brothers to Apollo landings. That still blows my mind.

You should invite elon musk

What a dumb debate.

Don't focus on distant fantasies. Planet earth and masses of suffering human beings are in desperate need of attention and improvements. Outerspace for the satellites necessary for international communications and weather observations is one thing. Beyond that it's a total scam, a waste, a selfish, criminal action by a clever, shrewd bunch of devils who are exploiting the masses to fund their hobby. 😉

The golden age of space exploration has yet to begin. India, China, the ESA are making big steps. More startups are joining the race, more countries like Turkey, UAE, Saudi Arabia are enhancing their space tech.
Shit is going to be good

You murdered your best president what a bunch of loosers.

I need help with my new years resolution.  I've figured out how to change the stars.
My idea for changing the stars includes Orion and Pleiades (Subaru).  I figure it's time to put something up there that's relevant to us, don't you think?  Take Orion's belt and Betelgeuse becomes the head with a baseball hat.  Below the belt are two legs bending at the knee.  The feet aligning perfectly under the bent knees.  The 3 stars of Orion's belt align perfectly as the 3 fat belt loops on a baseball uniform.  The spear pointing at "Subaru" is the bat being swung and "Pleiades" is the baseball flying away after being hit.  Put it all together and you get, "THE ALL-STAR."  In my case, I see a left-handed batter and I imagine a "7" on the jersey. Which makes him, "Mickey." (As it should be ;-) But you can put any number you want, making, "THE ALL-STAR," any player you want. It'd  be wrong of me to not, at least, try.  This is me, trying. Pass it on, please and thank you. Don't worry, where I come from, crazy is a compliment.  ;-P

U guys will get all the answers once u explore your soul with...that is the ultimate science

I would hope in 100 years we will be interstellar. There need to be some modification to general relativity to make this happen.

Love World Science Fest! Welcome back IRL!❤

i thought the introduction was a add for a new paradox game

(FALSE ALARM...not enough gravity to matter!! SOB!!)To calculate the approximate gravitational force, we need to know the mass of the object generating the gravitational force and the distance between the object and the affected body.

In this case, let's assume the mass of the object generating the gravitational force is 1.25 million kilograms, as estimated in the previous response. We'll also assume a distance of 100 meters between the object and the affected body.

Using Newton's law of universal gravitation:

F = (G * m1 * m2) / r²

where F is the gravitational force, G is the gravitational constant (approximately 6.67430 × 10^(-11) N(m²/kg²)), m1 and m2 are the masses of the two objects, and r is the distance between them.

Plugging in the values:

F = (6.67430 × 10^(-11) N(m²/kg²)) * ((1.25 × 10^6 kg) * (5.972 × 10^24 kg)) / (100 m)^2

Calculating this:

F ≈ 9.3 × 10^7 Newtons

Therefore, the approximate gravitational force between the object with a mass of 1.25 million kilograms and the affected body at a distance of 100 meters would be approximately 93 million Newtons.

😮😮😮😮well ingormeti0n good show 😅😅

In worldly conflict we like to war game country vs country. When it comes to space all of earth bands together - it is wonderful.

Brian, you're a physicist, your comments about the covid vax sound like cheap commercial for Pfizer - vastly inaccurate!

only 41k views? humanity is doomed

What a BORING discourse! Nothing new, no revelations.......NASA guy is quite amusing......Prof Greene must've thought the same as myself and many others. Dull, dull, dull.....

It takes billions of years to create intelligent life.. the bible and kuran managed to make people dumber in only a few thousand years

I just hope people get smart and look to science to make the world a better place.. religion has damn failed us thats for sure

At 25.53 ..... this is the pinnacle of thw WSF 😂😂😂😂, i love it 😊

I'm sorry Mr. Green but if the speaker guest presence cannot be there with you in person then don't come!

I can't tell you how happy I am these videos are back! I think I watched all the previous ones. These discussions are the best! 👏

all science and space program of human are fake 1 billion % and many many proof
