The End of Life on Earth

[@kimberlyperrotis8962]

Excellent talk, but Gresham lectures always are. I hadn’t heard about this asteroid.

Enjoyed it from start to finish ☆☆☆☆☆ Wel done Catherine , best astro narrator ❤

Bit of a slow talker, though.

Absolutely fascinating…if somewhat disconcerting! And the lecture so lucidly presented. Loved it

[@elainemagson213]

"Not a great outcome......" What an engaging talk- in spite of its horrendous subject, and especially for those of us who have very little knowledge of these things. Thank you.

'heading our way... that is including the earth and the moon' ... lovely.

Brilliant, illuminating! lecture. Thank you.

Greetings from Sweden! Very interesting talk. You just got yourselves a new subscriber 🎉

[@joeguerra8435]

I didn’t know about this asteroid. Talk about a near Earth-death event that wasn’t broadcast globally. Astounding. No words.

[@rapauli]

It is perversely refreshing to learn there is a real extinction event that is not directly caused by humans. Likewise it is disturbing to be reminded that we are not giving any effort to attacking human caused global heating. We just need universal vigilance. Snap.

A great lecture!

[@maggieadams8600]

That Saturday I was walking around a friend's house whilst looking up at the moon and sky, because it looked so magical! After about a quarter of an hour, I persuaded them to go outside to look up at the moon, which they did, and as they were looking, I saw what looked a lot like that asteroid you're talking about, but everyone says it wasn't visible from earth, so maybe not. I've never seen a shooting star, or anything like that before, but it just seems like such a coincidence. It was early in the evening and there was no rain in South Lincolnshire. Thank you for the talk it was so interesting and illuminating.

23:12 A solar system object or small body would broadly describe the asteroid or comet that caused the K-PG event without the specifics of volatile material composition to determine which it was.

[@jennyaskswhy]

Is there a television channel where one can watch topical public lectures of this quality? I need to leave KZbin for a while.

[@thesunexpress]

@25:50 NONE of the pictures shown are of the Morokweng impact crater, at all. The images shown are actually those of Meteor Crater in Arizona & Lonar Lake (the one containing water...) crater in India. The Morokweng impact structure is ~70 kilometers across & scarcely identifiable by sight from either ground or air. How the heck is it that these images weren't verified beforehand?!

Interesting lecture Katherine

If the Tunguska asteroid had arrived six minutes earlier it might have destroyed Moscow, thus avoiding WW1

[@elfootman]

29:05 that's not the Vredefort crater

[@jamieliddell9816]

Doesn’t seem like the Morokweng one’s right either: that pic isn’t of a crater 100+km across, and apparently the Morokweng impact structure isn’t visible on the surface.

[@AzimuthAviation]

Correct... it is Arizona's Barringer Crater.

[@johnclamp1535]

Yes the pix are wrong bcs there is no ‘crater’ at Vredefort

[@neiladlington950]

Not to undermine how close the nearness to Earth the Moon is but nevertheless the distance is 238,855 miles away from Earth, which is about 30 Earths away. The photo of "Earth rise" makes it appear much closer than that.

[@davidwilkie9551]

With the rapid advances in Rocketry and AI, there is a convinced case to make for Robot Observatories out in the Satellite parking orbit region beyond all the clutter and micro impact risks, asap.

[@myparceltape1169]

That means it needs to learn what to look at. People can decide to look at a location but how did they learn how to choose the location?

There's a whole video about what if the Tunguska asteroid hit London: What if London was Destroyed in 1908? by the channel Possible History

[@bardmadsen6956]

Serious? Personally, people are not taking the subject seriously by ignoring the tens of thousands of secondary impacts of the Carolina Bays and Nebraska Rain Basins put in place by the Younger Dryas Impacts Theory, plus Burckle Crater and tsunami chevrons. That temporal graph is missing pertinent data! Also, read my work about what Mankind says about the subject of the Ages of Man, there have been three Space Falls that we recall. There are two prudent priorities, avoiding destruction from above with Impact Winter and doing ourselves in. Sure doesn't look like anyone wants to collaborate. Eerie, how the Tas Tepeler Peoples, and universally, knew more about the most recent Meteor Stream than we do now as we unknowingly play out the ancient tradition of the Festival of the Dead, stripped of its New Years designation, when the Halloween Fireballs happen.

Global government and global digital communications and public transport with appropriate surge capacity to move many people quickly and housing resistant to electro magnetic pulse radiation gives people the best chance and reduce casualties to a minimum is the only way to preserve our species. Most people were lost to electromagnetic pulse radiation in their homes living ordinary lives during atmospheric atomic weapons tests between 1945 to 1960, housing needs to be better than masonry and more sustainable, with asteroids it’s the same hazard✌️❤️🇬🇧

Thanks to geologists we think that all living beings on our planet Earth have the most to fear from an asteroid impact or volcano eruptions. But when we look at the many horizontal layers that we find everywhere on our planet, we clearly see the effect of a repeating cataclysm. These disasters are mentioned in ancient books like the Mahabharata from India and the Popol Vuh from the Mayans and others. They tell us about a cycle of seven disasters. Certainly, a cycle of regularly recurring global disasters cannot be caused by asteroid impacts or volcanic eruptions. The only possible cause is another celestial body, a planet, orbiting our sun in an eccentric orbit. Then it is close to the sun for a short period and after the crossing at a very high speed it disappears into the universe for a long time. Planet 9 exists, but it seems invisible. These disasters cause a huge tidal wave of seawater that washes over land "above the highest mountains." At the end it covers the earth with a layer of wet mud, a mixture of sand, clay, lime, fossils of marine and terrestrial animals and small and larger meteorites. The Northern hemisphere is covered with a layer of ice that fell down "in blocks as great as mountains". These disasters also create a cycle of civilizations. To learn much more about the recurring flood cycle, the re-creation of civilizations and its timeline and ancient high technology, read the e-book: "Planet 9 = Nibiru". It can be read on any computer, tablet or smartphone. Search: invisible nibiru 9
