Geology in Space: Meteorites and Cosmic Dust
HTML-код
- Опубликовано: 8 ноя 2024
- Geology no longer is the study of the Earth. Rocks are found throughout the universe on other planets, asteroids and comets and as debris ranging in size down to the tiniest pieces of stardust.
In the June London Lecture Matt Genge, a planetary scientist and geologist from Imperial College London, discussed the geology of space, recorded in meteorites and cosmic dust, showing that the principles of geology still hold true far beyond the bounds of our home world.

He cracks so many jokes and the audience is so, so quiet...
he needs a hug
Truly enjoyable lecture. An hour well spent.
Excellent lecture. Space rocks are amazing.
Hi Prof. Genge...thank you for your lecture.
What's with the postage stamp sized screen ???????????????? [Aussie in BC]
Incorrect that most of our heavier elements are made in supernova. Those are the fast process heavier elements, like half way above iron. Most of the uranium, radium, and such, like thorium and rare earth's are made in neutron star collisions. This makes we humans more aware of where we came from, originated, and condensed just before the Earth sun cloud condensed. It seems these explosions happened shortly before the Earth's cloud condensed because of the decay of these heavier elements. Shortly of course means a few million years, not the billions since the start of life. Then 600 million years ago the pre-cambrian explosion took a couple billion years to start after algae photosynthesis occurred in our oceans. Anything could have happened to that life to snuff it out in a span of so many years. Close gamma ray burst, impact of a large rock over just 20 miles in diameter. So many chances that must have just missed us in a span of time so large.
Aye people just think that when a star goes supernova it makes all the heavy elements. But like you stated it's really the neutron star collisions that make them
Very good lecture but a strange format.
Sir i have cosmic dust meteorite how can i sell thank you
I have a 12 pound primal meteorite unclassified but definitely not just an ordinary rock was found in a rock quarry in Dryden Texas just like one in lecture
Sir I found a metallic stone here in the Philippines heavy of its size, magnetic,almost 4 kls.
👍👍..☄☄..saludos desde Argentina 🇦🇷
I can almost guarantee if gravity was X's 10,000 microbes would just smile. Run the temperature up to 220° Fahrenheit and the smile will turn in to a frown and vomit.
Thank you!
Has the following event that happened years ago to me occurred to anyone else? While standing on my front
step early one morning observing the cosmos a bright shaft of light approximately two or three wide by, again
only approximate because it was instantaneous, twenty feet or more long flashed in my neighbors driveway directly across the street no more than thirty yards away….I think it probably was a meteorite…Anyone?
Yes, it was probably a meteorite. You missed out, because meteorites are very valuable, especially those which were seen to fall. You should have searched your neighbour's drive, Value varies according to type, some are rarer than others, and size of course. Even the commonest types are valuable, the rarest worth a lot more than their weight in gold.
In his answer to the audience's question regarding the idea of panspermia (the transport of organic, molecular, or fossilized life forms to the Earth, or other cosmic bodies by meteorites) he avoided acknowledging that there is a legitimate argument that meteorites from Mars such as Nakhla have shown evidence of fossilized nanobacteria and micro -organisms WITHIN the meteorite. He studiously only made reference to the EXTERIOR, saying that there was a high probability that any evidence of life forms would not survive the entry and/or the specimen would be contaminated by the yrttestial contact. I believe he is wrong. His argument fails as we find more and more falls that contain nearly all the amino acids, water and morphology representing the building blocks necessary for life and evidence of some form of life like activity. I reference Allende, Murchison, Nakhla and AH0084.
airmuseum "... I reference Allende, Murchison, Nakhla and AH0084.?
===== The current consensus of the 20 years of research, as relayed by the primary researching lab very recently, is that the evidence is against life being indicated by AH 0084-01. Carbon isotopic evidence was cited as being entirely inconsistent with biology.
Amino acids and other organics such as cyanides, alcohols and such are common in space, and represent surface-catalysed chemistry on dust grains. While such organics could be starting points for life, they don't indicate life actually exists.=====
psycotria I can't argue ignorance. Ai least a dozen peer reviewed papers have been published by dozens of academics in Meteorites and Planetary Science and a other relative publications that support my contentions.
having seen allot of meteorites even really big ones achieve temperature so high,,that the internal materials are affected,,, excuse if I'm wrong
should we not believe that life may have occurred here during a time of low atmospheric pressure allowing things to fall with less friction. in a similar way that early technology may have worked at times of different electrical activity in our atmosphere,,like polar shifts and solar flares, Mars and the moon have little or no oxygen,, lowering the carbon decay rate,,but also allowing things to fall slower. ,maybe something activates the amino chondrules when the needed conditions are are met
The evidence is weak , his opinion is conservative , silence on the topic means he told you no lies , that's the way to be respected in your field , never be wrong , watch how a scientist presents " iffy" topics or turf , ,dive in !
How rude to reduce the speaker to such a tiny image' terrible sound distortion.
❤wow nice sir thank you ❤
Hello I wish I had a very strange meteorite mixture dotted red and black
Hello
We have meteorites Chondrite H5 and carbon CO3 for sale .
Thanks
very nice
Sorry to ask what rock is this on this video in this link:youtube.be/x060TrxJtpU
How to send you a stone picture
Amazing Lecture,
Please mute the claps from now on, they destroy my speakers and my eardrums
i have some sir im a new subscriber from philippines
NASA and geology hang in there my time capsule will be reality+ + +
❤❤❤❤
It's so quiet
my dream job
It's snot hard ; till it kills ya...ya know?
Всі залишки зіткнення Марса з кометою, випадають в Україні, до цього часу!
Туди хасіди приїздять!😉✌️
Tengo una roca con todas las caracteristicas me gustaria saver que es soy de argentina y aca es muy dificil nadie te atiende.
Nice video. But tell Geology that you have 100's of iron stones. They will turn around and say no you don't. tammytlc4943
where did you learn "geology"? Do you not realize that many meteorites contain some amount of iron? Do you understand that iron is a mineral which is in the earth, all over the world? Have you actually done any research on geology of your own? Have you taken any classes in geology (beyond any high school bollocks) in which you stayed awake and/or showed up for enough of them to learn anything? If so then you wouldn't write something so idiotic.
This is science , a good speaker , try listening to it twice or three times , bravo more , I want to know more about metiorite s , the strange ones the unique ones the contradictory ones . And focus on how they appear , surface details up close and in focus .
IAM ameteorits ameture collected!! more bits I got
Bravo ! Good talk , update please ! And ,sorry to say , your pictures aren't getting across , not detailed enough , up close , polorized light , sunlight , black light , and pointers can't be seen , used a stick..and textures and specifics , and rare ones !
33:38 Fact, this is a Martian meteorite!.... Where can I sign up for a job to say stuff like this? Who in their right mind would believe they possessed a martian moon rock from outer space?
I do , 5 years in geology at collage , most believe it to be from Mars ..the life stuff most are unconvinced , it's weird , it's from Mars. ,but is it bacteria? Prolly not , cause ? The rovers didn't find similar bacteria on the surface ... Odd hey?
He explained earlier in the lecture how they know a meteorite comes from Mars.
👍
موجود حجر الجنه الاسود اغلى حجر ممكن تطلع عليه
,,,,😊🤝
What happens when people stop believing this bs?
Slab city California , Google it
Too,booring is the name of that lecture
Not enough dancing pink elephants?
Sir i have cosmic dust meteorite how can i sell thank you
