I love how Osiris just shot a package at us then went on its way to another mission. It's amazing how just over a hundred years ago, we were just beginning to fly via the first prototype aircrafts.
In one average human lifespan (100 years), we went from paper airplanes that could only fly for 30 seconds, to landing on the moon
Edit: more accurate terms (blame the "a generation is 20 years 🤓" people)
Edit2: Stop replying to this comment, I'm done with the people arguing over bullsh*t for no reason. It's pointless.
@@akidafloofmy grandfather is still alive. When he was born in 1934, flight was still new - slow airplanes with propellers. By his 30s, he was in the airforce flying F4s at Mach 2. He's actually disappointed at how little progress we've made in the last 40 years.
my great granny was born 1900, she died in 1998. when she was a little girl, dreams of making it rich was dreaming of having a house with several fireplaces and having a personal horse and carriage. she saw the first flight in our country in 1910. she saw the first cars... If she had said "when im 50 they will fly to america by the hundreds in them, everyone will have a car and when i am 69 a man will walk on the moon" she would have been put in a straight jacket. She was born when sending a letter to australia was a 6 month endeavour with a 70% success rate. When she died you could have live videocalls globally. Its a miracle she didnt go crazy :D

Excellent treatment of the material. I've been following this topic for half a century, since I was a child, and it's exciting to see the developments in knowledge, detection and potential options for dealing with this threat.
Thanks for resisting the temptations of shallow content and clickbaity titles! I'm subbed and I'll be looking forward to more videos like this one.
Well done! It's nice to watch a reasoned discussion of a potential asteroid impact rather than the sensationalist click-bait you typically see.

People want to believe, so they do..It’s the new satanic religion, Scientism..Belief in unproven theory (Relativity, plate tectonics, Astronomy, Darwinism,etc) takes faith.. Non of it is Fact!.. You just believe it because others do…Sadly

(Oh, lose the big red arrows. Tacky.)
OSIRIS ftw. Fascinating topic and great content. Thank you Dr. Miles.
I wonder what our technology will be like in 30-40 years from now. Which is pretty much the time I have left. Unless I somehow make it into my mid 80s. Which I doubt, unless I make changes to my lifestyle.
I hope there's a technological leap during that time. Probably not as great but similar to the kind my parents have experienced. They were born in the 1950s.
Welcome to the club. I am half way there too I ges. Time goes fast if you really think about it and seems to go faster each year. I am at the point to make a decision to change my live style for the better. Not that it is bad now. But more in the sense of doing things I really want to do. More peace and rest. Changing my job and back to school.
Yes I too find it fascinating to see science at it's best. In mine younger years I always watched Star Wars, Star Trek, Star Gate, all of them and wondered how it would be like to be there. But the tricky part is that technology seems to go forwards on a rate that we do not realize that it has changed very much already. Think of the times without hand held phones. Times that we played outside and late at night watched the sky and wondered.
The needed tech is here now and will be greatly enhanced in a few years. Check Spacex Falcon-9 launch rate. Wiki shows F-9 throw weight is more than enough to put a nuclear missile (if one were purpose designed) into deep space.
There will be more than 120 Spacex orbital launches next year. We have 600 B-83 1.2Mt bombs in inventory today.
All we need is the right delivery vehicle (missile) and we are quite good at producing those.
Each F-9 launch can place a 1.2MT missile on a threat. Spacex's new Starship can put a dozen or so into deep space.
Both are reusable launchers.
Really, the tech is here today. We just have to build the interceptor with off the shelf tech. And it could be done for $20 billion or less if you wanted to build 100 nuclear armed, deep space missiles. These then could be mounted in F-9 rockets to put them in orbit to launch toward dangerous asteroids.
If we had a 1km planet killer detected 10 years out, we should be able to deflect it enough (years from impact) to cause it to miss. Subsequent hits could clean up any large debris.
This is no longer a thought experiment. We could begin to prepare for it today and have 100 interceptors in stock within 5 years, complete with a greatly expanded fleet of (Spacex) launchers (which will happen anyway).
We won't have any technology...
What are going to do, shine our crumbling solar panels and rusted wind turbines at it?
There is a Movie called I Robot. It is the closest thing I can speculate the future will look like. Everything is Automated and easy to have, yet everything is outrageously expensive. The one thing the movie does not show is pay status. It does show wealth from not. But it does seem as if everyone is well off. I do understand that is not possible. But I do see a fully automated technological society that sstill pays for merchandise because the Capitalist view is not destroyed with-in Society itself.
@@rafaelgonzalez4175 Yes great movie and ahead of it's time but that of course is obvious I mean more in the sense of realistic of what could be in the future.
An interesting idea is The Venus Project from Jacque Fresco.
There are some beliefs while designing this social structure such as, 'the collective progress of the world would still be better in the resource based economy than that in the current monetary system. In the resource based economy system all the dirty, routine, apathetic jobs are made to be done by the machines with no human employment. All the basic needs of each human is served; Everybody believes in equality and love, there is no greed. So that people will only be driven by their passion and curiosity, they choose their own areas of interest with no compromise for the collective progress. Each individual's interest will origin from his/her own perception of the world. But the collective progress can only be optimized with a balance in the progress of different fields. So how to be sure that the balance would be achieved? How can we be sure that the exact required number of people (/intellectual effort) is on cosmology and the exact required is on anthropology? Though all the research fields might be ultimately unified they still are different approaches. On the other hand with the paradigm of "unified consciousness" injected, if one compromises oneself, to choose something different then it would mean that the mission is still not completely accomplished.
Of course before we think of this question, it is essential to know what is the 'optimized progress' i.e, purpose of the human race, the dead-end puzzle of the quest. Unless you feel the answer is 'Nothing but just to do what interests one', the suggested freedom at work plan is a failure.
One simplest possible solution is to create a 'Matrix' and see what would happen. LOL.
Here, there is no compulsions on actions anyone needs to take. Assume every one participate with their curiosity & interest only with no intentions related to earning money and also that the interests are not much different from that they would have had if they are in a 'resource based economy'. Imagine that there's absolutely no monitoring or algorithms to selectively promote posts except that of "following an user or a topic". Now define a "PURPOSE" to the site. Anything you wish. And think what's the probability you can expect that it will be served.
i truly enjoyed this clip - its just really scary when you realize that earth is a not-so-large target in a shooting gallery where the trajectories of objects are dictated in both circular and straight-line principles. Its reasonable that nothing could be More than 100% spot on but dude, if i ever could... 11/10 for this discussion 🙂
Incredible content. I doff my hat to you, sir. I was afraid this was clickbait, but I was delighted to see the detail, realism and well researched content you presented. If only others on YT would be half as good as you.
Wow, first time seeing this channel & I loved this video, everything well explained w/out hysteria & very thorough.(Also made me glad I'm old & don't have to worry about Bennu!) Looking forward to combing thru recent videos in search of better understanding all the weirdness of the universe!
Half of it at least is nothing more than sci-fi. The other half is hypothetical

Great video, really like the informative pacing, kept me engaged the entire video.

Very informative. Thank you for making the video.
Very excellent video 📸👏 many thanks for making it and sharing it.
The whole point of Armageddon was that simply nuking the asteroid would fail miserably. Its pretty impressive that Osiris is reusable for continued missions.
Nuclear bombs can be effective at redirecting an asteroid if used far enough out.
It's funny cause during filming Ben Affleck asked Michael Bay if it was easier to train astronauts to drill than training oil drillers to be astronauts and Bay replied "shut the fuck up" 😆
@@PsRohrbaugh A nuclear bomb in space you say? Like a bomb that goes boom. A bomb that is physically attached to oxygen? Like a boom that can not happen if there is no oxygen? A Boom in Space is not a Boom on Earth. Try just saying the word Boom with no OXYGEN. You can't. If a Bomb went ka-boom in Space and you were right next to it, would you hear it?
@@rafaelgonzalez4175 That is not how nuclear bombs work though.
@@rafaelgonzalez4175 nuclear bombs create their kinetic energy by releasing energy EXTREMELY quickly by splitting atoms. They do not need an atmosphere to BOOM, their shockwaves are still as effective if not greater in the vacuum of space. The explosion of a nuclear bomb in space would not be similar to a explosion in our atmosphere, as with no resistance, the expulsion of gas would be bigger and look like a miniature star exploding. The US ignited a nuclear weapon in space, you can look up the footage.
Thank you for your clear and concise narration as well as a reasoned and informative discourse on this problem and our ability to take effective action. It also highlights the current impossibility of avoiding an ELE
This was very informative. Thank you.
Really enjoyed this. Thanks!
Thank you for good information .
I’ve learned a lot.
Excellent, clear explanations. Thank you.
The Deccan Traps are thought to have been on the opposite side of the world when the Chixulub meteor hit. The Deccan Traps were possibly created but definitely agitated by the impact when the massive shockwaves from the impact converged again, causing massive volcanism on the opposite side of the planet.
The geological establishment seems bound and determined to utterly negate the "Antipodal Effect", just as they did in the 20-30 years preceding Plate Tectonics/ Continental Drift going mainstream. So much for the settled opinion of the scientific consensus. So far it's Zero for Two. Any odds for the viability of the next outbreak of settled science? Will this post be stopped by the Al Gore Rhythms?
Well done analysis. Thank you.
Great video!
This is such a fascinating and well made video. Thank you so much.
this was so interesting. awesome job DR MILES
Very well done. Excellent information.
Even a rubble pile could be dispersed enough if done at the right time, so that only very small remnants remain on an impact trajectory, and most of them would likely be small enough to burn up.
You could send multiple mass drivers that land on different points on the surface and fire in sequence so spin isn't as much of an issue, and would provide redundancy in the case one or mor failed.
Yeah landing ion thrusters on the right spots and you can push it. The dart mission pretty well proved it can work IMO.
@@SamtheIrishexan You watch way too many movies. Just imagine the rotation and spin of an Asteroid traveling at a crazy fast lineage. You really think the ship or rocket involved would be able to match velocity with spin and rotation to have a level playing field just to look for a place to land. All the while gas plumes and asteroidal debris is breaking away from the rock at the same velocity in a different trajectory. Watch out rocket here comes a bullet in the form of a very small rock.
@@rafaelgonzalez4175 if the asteroid was spinning fast enough to break up into pieces it wouldn't be an asteroid, it would be a dust cloud :)
@@Axodus thanks for the detailed input.
@@rafaelgonzalez4175 Was just being realistic. The asteroid you were describing wasn't.
Well presented and informative vid. Great job 👍
Great video, btw. I really enjoyed watching it.
I am another that is fed up of click-bait, this video is definatly NOT one of them, the information is well put together, very informative, easy to follow, Ive passed it onto my childern and grand children as they are the ones that need to watch and think as we dont live forever my time should be a lot shorter here than theirs. I know in some cases some are not spotted until they are almost on us, but even that sceince is getting a lot better. A new sub here.
Thank you Dr Ben Miles for the time and effort that you put into this perfect video.
The "information" is all deceptive.
😂😂🐱🐱🐦.
The bit about the energy @1:15 isn't quite right, that wasn't the impact energy, that was the kinetic energy before it entered the atmosphere, it lost a lot of energy as it was passing through the atmosphere, most of the energy it had was absorbed by the atmosphere and resulted in the air burst, the actual ground impact was much less than 500KT.
Dr. Miles, you have a gift for explaining complicated subject matter. Thank you.
Brilliantly done.
1 in 2700 sounds terrifying. Needs more 0s.
The best estimate we have indicates a .057% chance of collision with Bennu. Our highest priority for metero defense needs to be short-term, fast-acting methods for the ones that surprise us.
Estimates as high as 6%, Apophis will hit.
@@mrrooster4876 "Apophis was the ancient Egyptian deity who embodied darkness and disorder, and was thus the opponent of light".
Has not astronomy an odd sense of humour? Ghastly entertainment at a cocktail party, eh?
Sorry, I'm not with you. It is logical, but not viable for humans. If something is so close and short time line? We are cooked. Nothing we can do. Unless, you are proposing we alter human culture, world human life, and our entire economic output.... to stop something killing us. It is romantic, but not viable. Humans need to live, eat, express ourselves and we can't just live under a regime of fear.
Let's put money and effort into stopping the things we can! But, let's also accept that there are risks and dangers we can't control.
it's actually 0.03
@@thebeanymac Yep. Pretty bleak sense of humour to name it thus !
Great info! Let's hope the right preparations are made so we can have a prosperous future.
Excellent video. I get into a mood of despair about the likelihood of a collision between earth and Bennu, or any other asteroids we may encounter in the future. It does give me hope that we will be able to address these threats when they come. We will be the first species in geologic time to do so.
Deep Impact was a vastly better film than Armageddon. Interestingly these two takes on cataclysmic impacts both debuted in the summer of 1998.
Lead time is the key to defense, and a blindsiding comet could show its face after slingshotting around the Sun without enough warning for us to react.
Great video! Very interesting.t
Nah, I was on the comets side. Never seen a film where I wanted everyone to die more.
They're both bad movies
Excellent update on these planetary threats!
Hello Hello From Canada!!! There has been so much research and projects to find ways to save the earth from an impact, but what about a major impact on the moon? Our planet is so reliant on the moon for tidal regulation, what happens to us if the moon is knocked off its orbital axis or slowed down by a major impact? What would happen to our rotation and what if it pulls the north and south pole alignment from its current spinning orientation? This was an excellent episode and after watching three or four of your other episodes, this one compelled me to subscribed to the channel. I really like the format that you present the issues and share all the details in such a clear and concise way. Everything that I watched so far, is technical enough to keep my attention, with great visual support that allows the watcher to genuinely learn and still be entertained. I'm looking forward to exploring more past episodes on the channel and I can't wait to see what comes next in current videos. Have you ever considered making a full length documentary? It would be fantastic to collaborate with agencies like NASA and DARPA or even other like minded researchers, to do some really in depth research on so many possible subjects. Being new to the channel, I don't know if you do everything yourself or if you have a team, but great work (you or team), keep up the awesome work and content. I hope you and all your viewers stay safe, stay healthy and are as happy as you possibly can be in all your future endeavors.
🤘😁👍
Thankyou Muchly Dr. Ben from AUS.
Great Video......very impressed and surprised to see how much progress NASA and other agencies are achieving in this area......so we've got till 2175 - I think we this covered like a jimmy hat
I’m not sure we really deserve to stop it 😅
I like to be in control of things and space freaks me out massively as it reminds me just how small and insignificant we are lmao. I was good at physics too in school but I was genuinely too freaked out by it to study it beyond age 16
Given the rate at which technology has progressed over even the last 20 years,a progress that seems to be rapidly accelerating too,its not difficult to imagine that by the time this thing is expected in another 150 years from now that we would have by then developed the ways and means of dealing with it.
That’s what I was thinking myself. As long as we don’t blow ourselves up, we’ll be fine. I have faith in the science.
Progress has been mostly stopped or seriously slowed down due to Marxist ideology.
@@bdfan4everAfter years of lies from “scientists” regarding Covid, lockdowns, masks etc as well as Marxist ideology dictating what they can say or do, how do you have faith in science? Very religious statement btw.
@@bdfan4ever Spot on.
The fact that people were more likely to be near windows during this event is tragic... Anything can happen, make the best of every day!
Really clear.Excellent
We can install solar sails onto the sides of Bennu, and have computers control those sails, from signals sent from Earth. The slight 'push' that those sails would have would be more than enough to keep it from hitting Earth. However, Bennu is a 'dust' asteroid, and simply detonating a large ground-penetrating nuclear 'bunker-buster' bomb onto Bennu would blast the dust into such a fine 'cloud' of debris that the threat from the impact would be removed.
We would still get a bit of fallout !
It would be a good idea to put asteroids into an orbit near earth ,for mining or using for solar shield
A gold rock the size of New York as our new close moon, would make a re-entery vehicle profitable. But to change the direction and speed of mass isn't easy.
It would only be a good idea if it were on the other side of the sun. If in any rotation during Orbit the Asteroid covers the sun from Earth, it will always happen at that instance. Then you have to hope it isn't in the way for too long a period. It gets colder in the shadow as it remains in front of Earth, No sun.
My biggest fear is not a collision, but a close encounter with a larger mass that changes Earth's orbit around the Sun.
No can't do, sir.
I can assure You, if there was only the force of graavity, planets would fling into dakness illenia ago.
fortunately,, there is an unrecognised by today's science,
a force called electromagnetism. planets do have their charge, electromagnetic reconnection with the sun and they occupy resonant orbits same as electrons in an atom.
take a look at electric universe theory :)
And that's less dangerous than a collision unless the object is so gigantic to move earth into a collision with either Venus or Mars
Nothing new.
Nothing with a sufficiently large mass in the solar system orbits close enough to Earth for that. The nearest star is 4 light years away and isn't going to close that distance anytime soon.
So there aren't really many options left. A random black hole passing through may go unnoticed for a long time. But given the fact that life on Earth has been around for billions of years, no catastrophic altering of its orbit has happened. The odds of it happening are just exceedingly small at this point.
Asteroid impacts on the other hand happen regularly, with various degrees of severity. It's definitely worth worrying about more than something tugging us out of our orbit.
@@Niosus I will blame you if it happens tomorrow! Mercury has a small chance creating chaos in the solar system.
the quality of this video is top notch
Very informative.
My son is taking an astronomy class. He asked me, "Where on earth would an impact of a 10 km diameter asteroid kill the fewest people?" I don't know the answer to this question. What do you think? I tend to think no place on earth is a good place for that kind of impact.
Siberia?
Australia? If something that big hits Siberia, it will also affect China, and China's population is quite large.
Tunguska was a 12 megaton explosion from a 200 foot meteor. It leveled 830 square miles of forest. I doubt Earth could withstand the impact of a 10km.
There's a theory about Earth's irregular shape that suggests a collision with a minor planet or asteroid impact, and Earth absorbed the mass.
I hope your son does well, and enjoys space as much as I have! And still do.
Tell him ''The Moon'' as everything else on Earth would be toast.
@@zedbear1
The Thea theory. The Moon is made from material from the Earth, this is known through the study of isotopes on both objects that are at identical points of decay. The Earth's axis is also at an angle meaning it was knocked off it's original natural axis. The hypothesis goes that Earth was struck at a glancing angle by a smaller planet, Thea, which blew material from the Earth and Thea into orbit while the Earth swallowed Thea's planetary core and after time the material that didn't fall back to Earth and remained in orbit coalesced into the Moon. This is fairly probable as the Earth has an inexplicably massive core for a planet it's size and the Moon seems to have been moving away from the Earth at a uniform rate since formation. It's also not uncommon for planetary collisions in our solar system as Uranus is knocked over 90 degrees onto it's side and Venus spins the opposite way it should suggesting it's been flipped upside down.
Will this asteroid affect the Taylor Swift Eras tour???
Legit blondes in one sentence
The question everyone is asking
Very clear language. Well done!
I think there’s only a few ways we could survive the asteroid.
1. Build deep underground vaults that would last for a couple years, enough amount of time for the atmosphere to comeback out and rebuild society.
2. Speed up on Ocean Exploration and even building Underwater Vaults deep in the ocean, basically the same as the first one but in deep oceans.
3. Sped up Space Exploration and Colonization, so humanity can colonize such as the Moon, Titan, Titus, Callisto, Europa, & Mars, maybe even developing large hovercrafts to float in both Jupiter and Saturns Atmosphere possibly.
4. Build a large space craft filled with at least 500 nuclear warheads and launch on the course for the asteroid and then boom, the asteroid is destroyed.
That’s all the ideas I got.
I want to know what size nuke they used in the simulation and if they drilled into the asteroid or not? We can certainly make a massive nuke if needed. The size would only be limited by the rocket but then again we could send it up in pieces. I think if it was the only option we could make it work.
All bombs on Earth are just chemicals in space. Earth has an atomosphere which provides Oxygen or detains Oxygen in its surrounding area to allow for explosions such as that from any bomb. To set a nuke off in space would not have an explosion. No Oxygen. The Blast may happen really fast. You might even see a spark. But no blast radius. No heat wave. Just radiation and a shockwave if anything. Which will just keep going forward until the shockwave hits something.
I sometimes wonder what a threat like this would do in uniting mankind on a level we have never seen. Its kind of sad, but at the same time instills a sense of hope.
It would mean rogue countries like North Korea would take advantage and make a mess of the world, knowing their enemies are preoccupied with something greater. Kind of like looters during wars.
Naw. The flat earth idiots and conspiracy theorists and stupid religious people would ruin everything

Even if we could prevent a potential catastrophe, during that time.. probably several years, what will happend with human society's? will it be anarchy, riots, why go to work when there might no be a future, stockmarket chaos, companies will be out of business', questions about where will it impact on earth and what to do with the people living there, etc, Make some thing on that topic!

Thanks for watching! What are your thoughts on how we'll handle potential asteroid threats in the future?
My thoughts, the military industrial complex is more a threat to Earth than risk of asteroid collision.
Until human beings learn to live with each other and stop spending trillions of dollars on war, it could prove disastrous. We need to concentrate on ending hunger, disease and war. Planetary defense should be included in this. As a military veteran I’m also aware that’s a tall order for humans, given our leaders apparent love of war………
Like the others, I don’t have a huge degree of confidence humans will do well in that type of situation, will it push us instead to make bad decisions? But as a scientist I hope we keep gathering data, creating options for the future and trying to make a better world as well
Do you think a nuclear explosion close to Apophis would push it enough to change it's orbit away from earth?
Don't worry about it. It'll miss us.
I had no idea there was a loose core fragment in are solar system. Thats so incredibly cool.
What music do you use? ,
Your documantation is very very good!!!
It's weird to think that something as simple as paint can significantly change the orbit of an astroid in space because of the change in albedo. Meanwhile something as destructive as an atomic bomb could glassify its target, making a large rock pile that could break up in the atmosphere an even bigger threat because it would be one large contiguous mass.
Sadly Atomic bombs only work in an Atmospheric location. Would not work in Space. It is a vacuum. Explsions are not like they are in an atmospheric location. Vacuum contains. Atmosphere spreads.
I don't think a nuclear blast is going to make an asteroid more dangerous. Also we can put water or something else like liquid nitrogen around the bomb so it will turn into steam and creating a bigger explosion than the bomb alone will make in a vacuum.
@@Slav4o911 The best thing about physics is that you have absolutes. Even if there was a way to create more force or energy than a travelling object in space at phenomenal velocity, the trajectory of the particles are as dangerous if not more.

If people were not here then we are now. Something survived the last rock that killed the planet supposedly. Something will survive again, and then people will be back. lol
@@rafaelgonzalez4175 No many small asteroids would impact with much less speed because they have more surface, that means more area for the earth atmosphere to work on, also easier to deflect. Like if for a big asteroid we may need a 50Mt nuclear blast to make into smaller ones, the smaller ones can be deflected individually, and even if not deflected they would impact with less energy. The most dangerous thing is for a big asteroid to hit us, with us doing nothing. Hitting it with whatever will slow it down, change it's direction etc. Smaller asteroids are not more dangerous even if they are many. If they were, the life on Earth would have been long gone.
@@Slav4o911 If you generate enough force to break a rock the force is added to the smaller pieces. The smaller pieces go faster. And they spread around the planet more. The possiblity that the pieces are going to miss the planet is the same as a bomb exploding in space.
I’m still voting for the asteroid
Asteroid 2024! 🇺🇸
great video
Wow! Yes, I think I have seen some of the Gloss windows that you're talking about! They're kind of shiny, right?
Any way to get it here sooner?!
Start with yourself

In the cosmic theater, a celestial stage,
Asteroid Bennu, in a cosmic rage.
A wandering rock in the cosmic sea,
Can we stop its dance, alter its decree?
Bennu, a traveler from the ancient past,
In the celestial ballet, a role cast.
Approaching Earth in the cosmic spin,
Can we avert the dance, the collision thin?
Scientists ponder, minds alight,
In the quest to protect, day and night.
Missions launched, with hope and might,
To alter Bennu's course in the cosmic light.
OSIRIS-REx, a spacecraft bold,
A mission to touch, a story to unfold.
Gathering samples from the asteroid's skin,
In the dance with Bennu, where destinies spin.
Gravity's pull, a celestial force,
In the cosmic ballet, altering the course.
Can we nudge Bennu, change its flight,
In the cosmic dance, the challenge in sight?
In the minds of scientists, calculations flow,
Plotting trajectories, a delicate show.
Can we stop Bennu, alter its fate,
In the celestial chess game, a checkmate?
Asteroid deflectors, a cosmic tool,
In the quest to alter, in the scientific pool.
Can we redirect, in the cosmic expanse,
Bennu's journey, a celestial dance?
In the silent realms where asteroids roam,
The quest continues, a cosmic home.
Can we, in our knowledge and cosmic art,
Alter the dance, protect Earth's fragile heart?
So, in the cosmic tapestry, questions rise,
Can we stop Bennu, in the celestial skies?
In the quest for answers, a cosmic plea,
To safeguard Earth from Bennu's decree.
Nice one
Bravo, truly a gift !
Look at what human beings have done to this planet, animals and each other for thousands of years now. Send it x
NO>>>>! Fix it and we are. Search...... 'InterAlley Cropping !'
Great video to watch before going to bed.
LOL
no worries i won’t be around
Same
You know the way things are going maybe just let nature take its course.
I hate to say this, but I see your point and agree 😕
I am a reluctant blackpilled accelerationist. I'd love for there to be a way out of the horrendous mess that's been made of things here on earth (I don't want to say 'we created' because the average human being ie most of the population, has very little to do with it) but we're gonna hit 1.5 degrees of warming this year - decades before it was predicted, and we're definitely hitting 2 degrees waaaay before the end of the century. People complained about the movie Don't Look Up being too on the nose and lacking subtlety as a metaphor but it was bang on for me. People don't believe it til they can see it, and by the time they can see it, it's too late
Ah, a misanthrope. Wondered how long I'd have to scroll to find one of you.
Humans are apart of nature, so us stopping it is apart of natural selection as well.
Stupid idea. Even if you hate humanity you can’t hate it enough to kill everything on earth as well
This is going to be a fun journey. :D Goodluck Mati you can do hardmode with ease i believe in you. As a soulsborne Veteran you have to :P
we already demonstrated the tech to approach an astroid and collect a sampleand return to earth. All we need its to adapt the tech. instead of a sampler. we add 3 things. A tank and spray nozzle that sprays some sort of glue over the rubble pile and a net and ion thrusters attached to the net. Spray the rubble pile so the surface it all glued together. it does not even have to super ridged just strong enough to contian the rubble under gentle pressures while the ion thruster do there work. The net then wraps around the astroid or cradles it. and the ion thrusters first work to stop the rotation and then once thats achieved drag it out of the collison oribit into a safer one. They then either detach from the net or simply remove the net still attached and fly back to the main craft to be returned to earth's orbit for refueling and reddeployment. With solid bodied astroids no glue needed just the net and thrusters. Small but constistant pressure applied over time would work over time that why I suggested ion thrusters. And not rocket engines. This apporach would only work it we have the time. If there is a threat that happens within weeks or a few months ... a different approach would be needed. But with Bennu we have the time to do a trail test and move it into a safer orbit. There is already huge understanding of glue in space. Should not take a lot of research to make one that is fit for purpose. If one has not already be made for use in the vaccum of space.
I have a big bottle of PVA, will that do ?
Fascinating. What I've been dreaming about is a rogue black hole entering the system before anyone knew of it, then you know, screaming terror planetwide. But this was another fear.
Dude is pitching only ads and unrealistic pseudo science
We won’t even be here then
We have just reached a point of understanding and technology that we can probably do something, if we have enough time and warning.
“Nah, I’d win” said earth.
Does it even Lift
Tell me, nasa is science rocket and so are missiles. Statistically what are the odds WE might blow up OUR Earth against the odd getting hit by some asteroid Ben ?
Btw, the carbon /toxicity footprint of the elephant in the room aka the military industrial complex Ben ?
Some people don't seem to understand, a large asteroid is rare but it is definitive, the end of humanity, game over, we are on Earth and there is no chance of escape, and this is something that has long been neglected together with the environment. All other tragedies are serious but easy to avoid, it's just a matter of political decisions. We must pursue all survival objectives and stop truly useless waste such as planned obsolescence and conflicts between peoples and societies, while at the same time planning together how to deflect asteroids, period!

Osiris project is absulutely incredible.
Considering Bennu has many more near-misses before it becomes a problem, it would be funny to see if we could deploy a package on it decades in advance and then control its orbit to a more desirable one.
The real question is SHOULD we stop it?
Come on man. It's time to open the blinds, let in some sunlight, and look at that glass that is half full.
Honestly no, we shouldn't stop it.
The question is will we still be here to stop it?
@@DSK248why? If we don’t survive it none of our wildlife does. What’s the point of having everything die?
Nah - it’ll be fine. Or maybe it won’t be. Either way, it’ll be fine.
Easy answer... They won't and they can't.
It's just propaganda. Nasa is just another euphemism for USSF (United States Space Force).
Im sure they could...did u mean to say it wouldn't help??
@@coryjackson6034 Nope, they won't prevent it, because it's impossible with today's tech.
@@braticuss yeah , but todays tech evolves into tomorrows tech , and that's where the answer lies.
Its easy to say that they can't, but the real question is if they should.
