The geopolitical space race - with Tim Marshall

[@clives344]

Good to see Tim Marshall again i miss him on Sky News. He really knows his subjects. He stands apart from others.

[@premyslvoska5914]

3:36 😅😮😮

[@vladimirp2674]

Couldn't guess Hipparchus, but sure he would be quite surprised if he watched this lecture by himself. And of course i believe that we might be amazed about 100 years passed from this very moment to witness next generation Ri lecture. Excellent job.

If you liked this talk about the geopolitics of space, you can watch the Q&A with Tim here: kzbin.info/www/bejne/fYOsdqKmmbuaepI.

The speaker asked who that guy in the white shirt in the black and white photo is. Sure didn't know - but he is Russian alright. That tunic shirt is so very Russian traditional style shirt you can pretty much get. And nope I am not Russian, just from a country on the border.

[@nandfednu3502]

the sound track for those booster landings was spot on

[@PatrickMcMahon-o8i]

Wonderful talk and talker.

[@lionelfischer8240]

Nice talk. Thank you.

[@burnere633]

SO many audio skips during the history section! :( I hope it doesn't recur throughout the talk.

[@funkymonkey1972]

Mind opening Tim! Thanks pal

[@freddyjosereginomontalvo4667]

Awesome and great video as always say.

The joke about the internet cutoff in Ukraine was misplaced. Often foreigners aren't fully avare of the circumstances of the war. The internet is crucial for communication in dangerous and unpredictable times, so it's presence or absence might cost someone's life. Just saying that war jokes is a precarious topic to play with 30:15

[@korbendallas5318]

3:20 I disagree, at least I can't see what is logical about a powerful tree-pusher. It's human though, we tend to put agency on things that don't deserve it.

[@RFC3514]

A lot of his rhetorical questions are probably meant to sound clever or funny, but just don't. The reason why I don't count down when starting my car is that I'm the only person involved in the process. When I'm trying to start something (or perform part of a complex process) in sync with someone else, I _do_ count down (or up, to a previously agreed number, like "press that on 2 and we both push on 3"). Even small children understand (and do) that. Also, his description of far-fetched theistic myths as "logical" suggests he doesn't understand what "logical" means. You could say they're _as good an "explanation" as any other_ (when you don't really have a clue), but there's nothing _logical_ about them. They're not even _meant_ to be logical (the whole point was to claim special knowledge that made the priests / rulers / elders superior; if it was something that could be arrived at through _logic_ then they wouldn't be special). Speaking of logic, saying that "he would have thought boats were falling off the edge of the world" as they slowly sank below the horizon is completely illogical. First, they would be "falling" incredibly slowly (no one would associate such a slow movement with "falling", based on experience). Second, those boats _came back._ So it makes zero sense to associate visual evidence of the Earth's curvature with "boats falling off the edge". Those are two separate concepts. And then you have some historically dubious references, such as crediting Copernicus for the heliocentric model when it had in fact been devised 1800 years earlier by Aristarchus, and ignoring the fact that neither of them describes planetary orbits correctly, and the claim that the Sun is at the centre of the universe is just as wrong (or just as right) as claiming the Earth is at the centre of the universe. In fact, any observer is at the centre of the observable universe, that's just a consequence of relativity and the Big Bang. It's just that treating the Sun as a fixed point makes simple calculations of solar system orbits a lot easier (but the full maths works no matter what you pick as the "centre"). And of course there is such a thing as "up" and "down", "north" and "south", and so on. Directions being _relative_ (to the Earth, in this case) isn't the same as "not existing". And then we get a diagram showing the Karman line in _miles,_ with such a specific number (62) that it completely obfuscates the point. There is no altitude where "space starts". It's not about "nailing it", it's about understanding that the atmosphere thins out gradually. At 10 km it's still pretty dense, at 1000 km it's practically non-existent, so the transition area is generally considered to be around the order of magnitude that sits between those two (in SI units): 100 km. Show the same chart in SI units (going 10 - 100 - 1000 - 10000) and that becomes clear (numbers are just rounded to the closest order of magnitude). Label it in medieval units and people assume there must be something scientifically special about "62".

6:15 They worked out the Earth had curvature, but guessed it was spherical for metaphysical reasons. Turned out they were right. Maybe the Earth was a doughnut.

[@TheAlskdfj]

The editing is bad in this video. Cuts off at so many points.

[@alex79suited]

The moon is a baby step, and Mars is putting one foot in front of the other. And that's how these places should be looked at stepping into the vacuum. If we are truly going to go into deep deep space, we will need to leave from there. Once we start really operating in the vacuum space, we will start to understand that this is what we are supposed to be doing, not warring with each other, but reaching for the star's. There right there, we can see them. If we can see them, then we can reach them. It's going to take everyone every Nation chipping in whatever they can. Failure isn't final, it isn't the end, it's our ability to get back up and try again that will get our species where we need to go. And we need to go let there be no doubt. If our species is to live on, then it's the vacuum space or it's nowhere. Let's stop the wars, we have a common goal. Just look up tonight and it will show itself. To those countries fighting right now, tonight look up that's the reason it needs to stop that's the common ground it's right there, just look up. Peace ✌️ from Canada, eh. Great video

[@MrTylerStricker]

Am I the only person who thinks Mr. Marshall looks like Sam Neill?

[@tibchy144]

Inserting all those unpleasant noises was a really bad idea.

[@ingoos]

If there is antimatter with atomic particles of opposite electrical charges.... Then, i would suppose that the darkness of space is actually negative light.

[@filipe5722]

Photons are their own antiparticles, so no.

[@gubocci]

Tapaisimmeko markkina-aukiolla, hyvä herrasväki?

[@opperhoofdgeilebizon]

Interesting talk once again 😊

[@sarcasmo57]

Very informative. Love the bad jokes.

[@pedromoreno4430]

So much control in the origin. Yo can control this, you can control that, you can know things ahead of others, you can control not only the world and the people in it, but the whole universe.... What a bunch of psychopaths.

[@johnlandrum4649]

If this is going to be the caliber of the royal institution lectures going forward, I'm certainly worried. This was laughable and ridiculous.

[@808bigisland]

Antique lecture. We’ve seen UAP. We are subject to galactic policies and politics. Terran politics are now secondary.

[@filipe5722]

😂😂😂

[@_aakashpandey]

Meanwhile Indians : 🦗

[@tensevo]

Why does science have to be made political ? Politics is tiring, I come here to escape that

[@Starfishtroopers]

Ignoring UAP in this discussion is showing the stigma.

[@filipe5722]

Not really. The subject is geopolitics in space.

[@hawklord100]

Just a nothing here type of speech...

[@AmakSevn]

If aliens arrive they would find the concept of nations to be very funny, single species diving themselves into imaginary borders on a rock floating in endless space thinking how great that is.

[@mateusneto6687]

Our the aliens could be in a similar state of affairs. Competition is a driving force of nature. They could not even have a homeplanet anymore, our be machines. Any alternative is plausible.

[@whcolours9995]

Decentralized civilizational control groups are the opposite of funny.

[@AmakSevn]

@@mateusneto6687 Marvel fan? :P

[@RFC3514]

The notion of an entire species _not_ forming local groups on a planet would be _far_ more surprising. All social animals form tribes. Even countries divide themselves further, into regions, counties, municipalities, and so on. It's a perfectly logical way to make sure decisions that affect a specific area are made primarily by the people who live in that area.
