The Earth's atmosphere is good for some things, like providing something to breathe. But it does get in the way of astronomers, who have been successful at launching orbiting telescopes into space. But gravity and the ground are also useful for certain things, like walking around. The Moon, fortunately, provides gravity and a solid surface without any complications of a thick atmosphere -- perfect for astronomical instruments. Building telescopes and other kinds of scientific instruments on the Moon is an expensive and risky endeavor, but the time may have finally arrived. I talk with astrophysicist Joseph Silk about the case for doing astronomy from the Moon, and what special challenges and opportunities are involved.
Joseph Silk received his Ph.D. in Astronomy from Harvard University. After serving on the faculty at UC Berkeley and Oxford, he is currently Professor of Physics at the Institut d'astrophysique de Paris, Université Pierre et Marie Curie, and Homewood Professor of Physics and Astronomy at Johns Hopkins University. He is a Fellow of the Royal Society, the National Academy of Sciences, the American Astronomical Society, and the American Academy of Arts and Sciences. Among his awards are the Balzan Prize, the Henry Norris Russell Lectureship, and the Gruber Prize in cosmology. His new book is Back to the Moon: The Next Giant Leap for Humankind.

This is an example of "old men [who] plant trees whose shade may never cover them" that simply melts my heart.
awesome discussion. Thanks!
OMG, is there something that Dr. Silk doesn’t know about the universe as we currently know it. I wish all interviewees had the same clarity of him.
I wonder if Robert Zubrin could convince him on the gateway/tollbooth question.
This is the most exciting episode I've listened to yet. Lets build that telescope!
Do we have the capability to conduct any type of operations in the environment that is. ( The Dark Side Of The Moon)?
Loved this one, resource exploitation aside The science and projects discussed were all so tangible

@@HarryNicNicholas no, not much of an astronomy buff personally. But I've heard about that and seen some utterly ruined graphs due to it. I just don't get why he would do it like that? Why not coordinate so that you aren't sabotaging other people's work?
😮 The conscious observer effect debunks the big bang theory whereas String theory and Fine-tuning prove the holodeck theory.. which is good news ultimately as holodeck scenarios are potentially eternal unlike true big bang universes which are not.. but this means that the sky is a projected image and the universe doesn't actually exist in reality. We are real though. Please discuss 🙂
Not counting the human cost of undertaking such a project

How do we calculate the "Equal" distribution of mineral rights to the moon, Mars, asteroids and so on? Or will it be the same as the Americas ? (show up with bigger guns or superior technology ... " I got Dibs" ?

I think it is less like the Americas and more like the oceans. There is not an "equal" distribution of fish, but you try to come up with international agreements to limit overfishing. As he says near the end, there are a finite number of good, dark craters for telescopes. If China was already building a telescope in one then Europe would have to pick a different one. There is already a Moon Treaty and an Outer Space Treaty to limit militarization and claiming anything as national territory. Most countries are not parties to these treaties. But there should not be guns up there in the near term. So, if the US was angry with China, and couldn't resolve it, then they would decide to hold "routine" naval exercises uncomfortably close to China.

Why should there be equal distribution rights? Only China and the US are seriously funding this endeavor. Your ‘concerns’ are so telling and a direct reflection of your politics.

@@coreyleander7911 I don't think either country cares about astronomy that much. I was hoping to walk the poster back from the idea that there would be military bases on the moon. Any conflict would primarily be on Earth. For example, if fusion power becomes reality, and one country began stripping the visible side of the moon for Helium-3, then the other party would go through other options: strongly worded diplomacy, taxes on the other's goods, even flexing military muscle, before they got to the point of launching a missile to blow up the mining operation. Guns on the moon would not be the first resort, as the poster seemed to be thinking.
I hate the term" we can exploit the moon". Have we not learned enough about the dangers of explotations of resources and environments yet?

There are different kinds of conservationists. Those who care about the harm done to people and living beings by damaging their environment, those who primarily want to conserve natural beauty for aesthetic reasons, and those who have some kind of spiritual belief that nature itself is living and conscious with wants and needs more important than those of people and animals.

Don’t worry, we ain’t going to “exploit” the moon any time soon. Old fart (meant with affection) interviewed on the podcast is a prime example of how expertise in one field doesn’t translate into expertise in other fields however adjacent. He speaks extremely confidently, and mostly wrongly, about mining, engineering, aerospace industry, AI, economics, etc. presenting everything as if it were far easier, cheaper and economically viable than it actually is. Actual experts in those fields say otherwise.

I thought there were "Laws" or Agreements to prevent Human alteration of possible ecosystems. Just because we haven't detected life in some places doesn't mean it isn't there.

So the moon has an ecosystem? So many left wingers in the replies inherently mad at getting resources from the moon. Bizarre stuff
There's no profit in researching in Antarctica.... It's all cost ... Shockingly people are nicer to each other when their life depends on it. To an extent.
Please people don't take away the 1 thing that is beautiful and free for all. The ability to step out at night and just look up. Planes and satellites have continuously done this for the last 20 years ...
Otherwise they would have to ship building materials, costing more $.
I was excited that I thought I would hear from a real expert about why the Moon would be a good place to do astronomy. There was indeed some of that, but wrapped in too much Artemis Project spin and recycled manned space flight talking points. What I learned, I think, is that the radio astronomers need to hurry and get a large all-robotic radio telescope set up and observing on the lunar far side while the level of human-generated radio noise there is still almost zero. Fortunately the human trashing of the Moon will take years, probably decades, longer than the Artemis lobby likes to pretend.

Why no mention of whales when talking about resources on the moon?
can't wait to see how elon's ego reacts to learning of this research.
So, we don't like that kids are mining the resources needed to make our smart phones affordable... and our solution is to get them from the Moon instead. Sounds about right.

It'll be "cheaper" or easier to launch anything from Lunar gravity..... The energy needed for significant cargo to escape Earth's gravity is expensive . This is why they want to mine on the moon. To build using local resources .
So... I'm not at all in favor of "Mining" the moon. Is there any chance we ,as a species... Can avoid exploiting every available object for $... The Fn Moon... Really? I don't think I could handle seeing lights on the moon Most nights.

How many comments are you going to make under this video from your far left politics? It’s interesting that you think it’s just fine that we run out of rare earths and other resources on Earth, and equate getting more with profit only.
