Defending Earth from Asteroids with Neil deGrasse Tyson 

Ever since I discovered Neil deGrasse Tyson I'm hooked, such a great scientist and human being!

I have never heard of Ed Lu before but he said something really cool. "100 years ago, that was bad luck, if it happens again in 20 years that's not bad luck, that's stupidity. And I think we, as a race, can do better." Go.On.Son. I just thought that was really cool.

Ed Lu makes me feel like a guardian angel for owning a telescope.

Great presentation and discussion by a wonderful panel.

I hold Neil Degrasse Tyson in very high regard and have seen countless of his speeches , but somehow in this interview I see him as humbled to talk to these people as much as I would be listening to him. Don't know if its just me.

The view count of this video is not reassuring.

thank you for posting! I did have things to do tonight but bah w/e Il just watch tyson for an hour.

It is a shame that we have to wait until something big happens before governments do anything.

Yeah baby. I am always searching videos with Dr. Neil deGrasse Tyson, so thank you very much for having him as a speaker and placing it in you tube to be watched by fans like me.

this is why i love youtube. tyson for an hour.

Knowledge and understanding , the key ....

where can I see the Asteroid Threats Report?

Anyone have an update on this?

Personally. I feel safer already. Surprised there was no mention of Chuck Norris, though.

It has been clearly stated by mr. Tyson in an interview, ''There's no way to observe all space at all time". Unless we've made a huge leap in technology, were still looking at damage.

As a biologist, you can think of astrophysics as the origin of your speciality. Biology came from the cosmos, is part of the cosmos and thus it is natural for you to find it fascinating.

Very encouraging. Thanks. Puts things into a more comfortable (not complacent) light. I do wonder about progress in development of global force-fields (for example) to deflect impactors (and gamma ray bursts, wandering black holes, alien attacks, etc)? A pretty tall order, but what's the thinking on protecting the species in the face of such other universal hazards? I suppose space colonization would be a good way to hedge our bets?

This museum is in NY right? Do they still have the Barosaurus skeleton in the lobby? Thanks for the upload! Very informative.

new Tyson video.. yeyy!!!

Any updates on this subject?

Well Now this is more important then ever

So cool.

The images shown at around 15:00 of the injuries sustained by the local populations affected by the Chelyabinsk meteor Event in Russia were caused by the effects preceding the atmospheric impact, rather than the meteor itself. The Chelyabinsk meteor was a superbolide that entered Earth's atmosphere over Russia on February 15th. 2013 at about 09:20 YEKT (03:20 UTC). It was caused by an approximately 20 m (66 ft) near-Earth asteroid with a speed of 19.16 ± 0.15 kilometres per second (60,000-69,000 km/h or 40,000--42,900 mph). It was so sudden and brilliant, the light from the meteor was brighter than the Sun. It was even visible up to 100 km (62 mi) away. Observed over a wide area of the region and in neighboring Republics, one eyewitnesses claimed to feel intense heat from the fireball. You've undoubtedly seen plenty of RU-vid videos about it lol there are MANY. 🌠 Because of its high velocity and shallow angle when it entered the atmosphere, it exploded in an, "air burst," over Chelyabinsk Oblast, about 29.½ km up. (18.5 mi; 97,000 ft). The explosion generated a bright flash, producing a hot cloud of dust and gas that penetrated to 26.2 km (16.3 mi), and many surviving small fragmentary meteorites, as well as a large shock wave. The bulk of the object's energy was absorbed by the atmosphere, with a total kinetic energy before atmospheric impact estimated from infrasound and seismic measurements to be equivalent to the blast yield of 400-500 kilotons of TNT. (Or; 26 to 33 times as much energy as that released from the atomic bomb detonated at Hiroshima.) Because the object went undetected before entering the atmosphere, mostly because its radiant was close to the Sun, the explosion created panic among local residents, and about 1,500 people were injured seriously enough to seek medical treatment. All of the injuries were due to indirect effects rather than the meteor itself, mainly from broken glass from windows that were blown in when the shock wave arrived, minutes after the flash. Some 7,200 buildings in six cities across the region were damaged by the explosion's shock wave, but people saw a bright flash and naturally went directly to the nearest window to look outside lol and, "investigate." Clearly, this presents a rare but significant opportunity for the rest of the world to learn what NOT to do in a similar situation lol if you see a flash brighter than the Sun, the LAST thing you want to do is go looking out the window! 😂

you got this, sir!

Good job to everyone on the panel. I really enjoyed watching the video.

I really like Neil...

thinking back, I think I can totally see where you're coming from. I also noticed that even within the engineering faculty, each branch makes fun of the other (mechanical, chemical, integrated all look down on others). human nature i suppose :P

Yeah!! Sometimes it is easy to forget that we, everything on this planet and the planet itself are very much in the cosmos and of the cosmos, we are made of the cosmos.

YAY, MORE TYSON! :p

No one is ever gonna do or pay attention to this up until something will be discovered to come and finish us

I watched armageddon Again 18 years later and come to the conclusion that we can send Bruce Willis to all of them and blow them up?

I initially clicked on the link hoping for a discussion of Apophis and the like. And got really disappointed by a discussion about the creation of committees and sub-committees. It's like trying to find a tutorial on how to win at football, and finding a video on how a football team works.

1chance in 10. One in every 10 years the magnetic field flips.

Hope to see that telescope in space soon.

"Use the force Luke" :) .

how about the idea of robot satellites out farther in our solar system to be able to detect these things. maybe have them working together to push these comets or asteroids away from earth.

and now we have the comet research group!

I'm a biologist and my favorite science advocate (by far) is an astrophysicist. It boils down to fire liking water. Am I bringing chaos to the universe?

I believe we have the technology to deflect an asteroid but I think it would be very hard to do.

Yes, the Barosaurus is still in the lobby.

This should have a 6 billion views

Neil suggests that each country could donate some amount directly related to their GDP (or other measure of wealth/production), but aren't certain countries more or less likely to be impacted by these asteroids? For a smaller asteroid that is a city-destroyer, wouldn't it make more sense to add a probabilistic component? Certainly, a larger asteroid that could cause an ice age would pose an equally likely risk to each area.

They are very aware of a potential hazardous astriod ..

damn they are sweating... you can see stopping frames how everyone reacts. this shit is going real i love it. thanks neil for everything thanks everyone

The UN will send the asteroid a sternly worded memo.

To be fair we don't actually know that. All we know is that they didn't ask any questions during the Q&A session.

With the fear maintained with nuclear strikes and spills, It may be a good thing to really enhance the odds on defending our selves. YVO

Huh... no mention of the asteroid Apophis. I am surprised, it falls under the classification they are speaking of as far as mass goes.

Ed hu is incredibly smart.

:) You may have just brought back balance to the universe!

While it is a nice goal, I have to wonder if all of this research might result in an asteroid hitting earth sooner rather than later. I mean, since when have we ever developed a technology that we didn't try to turn into a weapon? Once we master the detecting, plotting and nudging these objects, you basically have a very deadly weapon.

that was seven years ago... they warned us... thats all we need now in 2020

You get how that title reads, right?

Right now we're defenseless people

Beautiful mind. SMART American people. i love it. increase you intelligence. wow. ALL THAT I KNOW IS THE FACT THAT I DID NOT KNOW BUT NOW I KNOW A LITTLE MORE.

It is bittersweet (personally) for me to have been an excited and optimistic pre-teen who was one of the many millions to have witnessed Apollo live on the TV, but then to see the promise of more manned deep-space flight missions shelved because of shortsighted and petty political bickering. The sort of idiotic lack of vision for the potential of the Human species that now, coming up on the 45th anniversary of Apollo 11 next year, I wonder whether I will live to see the inevitable first manned Mars expedition.

dec2019=no public plan

Could an asteroid pass by so close to the Earth (without striking), as through the upper atmosphere, that it might pull a significant volume of atmosphere with it into space?

Maybe it's something I'm experiencing at my university but there is a lot of disdain between fields of science where I'm from. We mock biomedical sciences for instance and they mock my field of marine biology and evolution. If I tell my professors that one of my role models is an astrophysicist I will get laughed at. But, all in good fun of course!! Just take my statement with a huge grain of salt.

you tell me

We won't always have 15 yrs warning!

Hopefully NASA has upgraded this issue since 2014. This is unacceptablely too old

to bad the big guys are so hard up building there obsolete rockets and thrusters. My VCMD prototype works.

Imagine a hall pass written by Neil deGresse Tyson?

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

but since mars is closer to most of them its better,thier income,vs job flutuations.then there is its metal storage capabillity.i have to say it,its a space mining colony.the glory goes to its redesigning of solar systems.

Let's catapult Tire Irons for 10 ton trucks at incoming space rocks.

The Astronauts are going to save us.

we need to have more than 1 plan on have to deflect an Asteroid, because we don't know how much time we are gonna get to deflect it in, we need to have plan a, plan b, plan c, and so on, because it depends on how much advance warning we are gonna get to deflect it in, a day, a week, or maybe a year, who knows,we need to be ready for it. !!!

the romania fauxpass...dude, thats just something you dont get wrong ;) otherwise very interesting presentation.

WHY CAN'T I HEAR THIS?!?!?!

I wouldn't discard Dawkins though. He's as passionate as Neil.

the third from our left is an romanian ,and went to space once in 1983,...they all went to space sure ,how many times :1

Oh, it's actually romanian accent that everybody in Hollywood thinks is russian accent

heck no! science rulz

2:27 is what you came here for.

AI will identify and track near-Earth asteroid threats. I think the theory of being able to deflect an asteroid's path has been proven on a small asteroid.

Never mind, I found it!

Dear panel of scientist...this video is a little getting older now....it is now the year 2020....can I ask how much development have there been so far as far s deflecting the real threatening asteroid ( that’s asteroid Apophis ) that’s on its direct path in our galaxy towards earth....and where are you now with this international space program with its deflection before it makes its first pass on earth by 13th April 2029.....do we have a big chance of surviving it with its second pass on same date on 2036 even if it’s only deflected a tiny little away from earth at least before 2029.....can you give us a little bit more honest information please..>

Where in my comment do i strictly point out a uniform mindset of every individual on earth? I admire and wish projects like these every success however their actions are like trying to bail out a sinking cruise liner with a thimble whilst a tsunami approaches.

not sure how a biologist liking astrophysics is like fire liking water :S isn't science pursuit of truth?

Invent a DISINTEGRATER GUN💯 like Marvin the Martian has!!😁

given tools are closer than a good brain.asteroids can.give vesta to mars,move venus,or mars.interupt any comet.and from a military stance great battle ships.the question is which ones have mineral wealth.

how bout defending earth from the gases of uranus

Did you notice there was no major MSM rep there? CNN, BBC. I find that level of un-interest pathetic.

did you have anything to do with earth's creation.. or your own?

Yeah, UFOlogiests :). Didn`t we lost earth already in 2012?

There are 45 Ken Ham-ers who tried to watch this video

elon musk should be up there since he will probably be the one to save us when the time comes.

Fantastic..his theoretical red line passes over my country 😦😦😟😅

Dear blixx66...I just read your clever comment and wanna THANK YOU for making me LOL for Real !!!

there's just ONE space romanian out there and Neil degrasse tyson gets him wrong :((

Surely there are :D World is full of crazy people.

Neil @ 2:30.

I wonder if there are any asteroid-deniers out there?

Except the Bible has nothing about asteroids hitting us. At least until the Tribulation; then the Earth is toast.

Defending Earth from Earth haters with Neil deGrasse Tyson

I find smart people to be intellectually attractive.

8 People want the Asteroids to hit out planet.

Yaaaaaaaaaaaaay :3
