The Oort cloud is the one that REALLY scares me. We could have an object the size of a moon thrown at us, or already on a collision course, and we wouldn't have the faintest idea because it's so freaking far away we still expect to find new PLANETS there. And even if we detected something centuries before it hit, there are some rocks out there big enough that we could do literally nothing about them other than get a move on those offworld colonies. Living in a planet is like being a sitting duck at the cosmic shooting gallery.

I’ve actually seen a meteorite fall from the sky and then it lit up the entire mountain like a camera flash, then a few seconds later the floor shook like a huge truck was going past. Coolest thing I ever saw in my life

my question on the smaller deadly rocks bit is wouldn't that also up the surface area and thus up the odds that they would then burn up on entry?

Not sure if this has been asked, but could the concussive shock wave of an explosion change the trajectory of an earthbound object?

Seems like somebody went to the Griffith Observatory :) great video.

There's less comets than there are asteroids.. it depends on the size and density of the comet.. if it's quite large then it will be attracted to the sun.. it'd then need to be attracted back towards jupiter when jupiter was at the right position for it to hit earth.. there'd be about a 1 in 360 + chance of that happening.. most comets would be attracted to jupiter I'm guessing... but the really big ones that we see every 100 years or so are the ones heading towards the sun's gravity. so.. 100 x 360 = every 36,000 years a comet would hit the earth... "Halley's comet will next appear in the night sky in the year 2062. It orbits the sun every 75-76 years, so this is the time between appearances. Halley's comet was recorded by Edmund Halley in 1682. It was seen again in 1758, 1835, 1910, and 1986." ok I was wrong about 100 years.. it's 75.. so.. 75 x 360 = every 27,000 years humans have been around for about 70,000 years. I guess it takes additional time for each of the 360 units of space to all be covered.. I'm not very good at mathematics, sorry :)

if that is how relative velocity works (4:22), then something at 1/2 the speed of light colliding with another object moving at 1/2 of the speed of light would make the collision be at the speed of light.

What's the difference between asteroids and comets/meteors?

Just learned this today from Science Asylum which is a really cool channel that I totally recommend you check out. "When people hear the word mass they think of rest mass which light definitely does not have. However, if you are an experimentalist then all you care about is what you can measure. In that case then light does have mass in every measurable way. Light can affect something's gravity and light can give things momentum when it hits them because it has this silly thing called relativistic mass. Rest mass + kinetic mass = relativistic mass." Nick Lucid said he is going to also do a follow-up video so subscribe to learn more. :)

Optimist: We have found 90% of asteroids. Pessimist: But we haven't found the other 10%.

Just yesterday I saw a Gif which showed, that probably the moon and its gravity behaviour with the earth is the reason we didnt get hit by an asteroid yet. Its nearly impossible to hit is, since the forces around earth are so strong for a thing of the size up to 50km in diameter. Which is pretty lucky. And secondly, today common sense is, that it wasnt the meteroid back in the days, which killed the dinosaurs. At least not alone. But an ongoing series of vulcano eruptions which topped them off.

4:18 : Actually it is not true. a 50 mph car crashing in another 50mph car creates as much damage as a 50 mph car hitting a wall. However the rest of this part is correct (The mythbusters tested it).

Considering what just happened this 11/9, I think that we need a very good old 5 km asteroid right now

My friends and I debate on this topic ourselves and I told him that the earth was covered with satellites and that when a big asteroid comes the sats move away from the earths trajectory and target the the asteroid with lasers. We were teenagers so I thought that comforting him by saying something I'm not sure of was better than saying we all can die any moment.

about the gravity tug boat thingie.... do we even have big enough space shuttles to change the course of a 10km wide asteroid using anly relative gravity??

A video on my birthday? I didnt think miracles could happen!

NICE!!!

3:00 I had to replay this about 10 times and am still laughing xD Great vid as always :D

Great video as always! Your relative velocities in a head on collision tho is inaccurate. To vehicles of the same mass having a head on collision at 50 kms/h does not translate into a combined speed of 100kkms/h.... It would still be as tho a car traveling at 50kms/h hit a concrete wall. Hence a relative velocity of 50kms/h. I know it sounds crazy but 2 cars having a head on collision at 50kms/h is not 100kms/h relative velocity it is still 50kms/h. Mind blown! Again great videos as always Adam

matter colliding with earth is simply coalescence of gravitational forces. we can think of this as leftover planet building processes and therefore assume that given time these events will lessen in frequency when given more time. I believe that, if this isn't already being considered our current estimates assume the next mass extinction event is closer than what we've recently predicted. also, didn't Adam and Jamie do some work on the force of two bodies in a head-on collision equaling each respective body rather than the sum of each body's velocity? I'm curious...

Why is there a correlation between size and time?

Makes you wonder if there were ever any precursor species that got to a tech level anywhere near us.

Once I saw a documentary about this. They showed that we could make a big enough solar lens in orbit that could direct enough power from the sun to change the object's trajectory.. Like that painting mentioned, but without the need to phisycally reach it ! =]

I heard that it was more likely a comet because they’re much bigger on average.

I have always liked the laser deflection idea. Shoot a laser at the object, vaporizing some of it's surface to create a volcanic plume that acts like a little rocket engine. However, I don't like the idea of if being a series of satellites. Our planet's orbits are already too crowded. I feel they should be based on the moon and use solar capacitor banks. Better yet, would be rings of mirrors able to focus the suns light to a single point at any distance. The moon is so far out that it would have plenty of time to work on redirecting the momentum of these huge, high energy masses.

well we saw the tunguska meteor explosion in 1908 and saw another incident with the chelyabinsk meteor in 2013 which actually caused property damage and injuries even though it detonated 18 miles above the earth. that tells us that our time here on earth is limited and we can only hope that we can see any large enough impactor in time, one that poses a significant threat to either a city or even an entire country. after all we have technology and theories on how we might be able to avoid going the way of the dinosaurs

That intro cracked me up.

3:02 I about DIED

If you now think that two cars running into each other at 50 mph each is the same as one car running into a concrete wall at 50 mph, then you’ve got that wrong. Because, when in the end, you’ve got two recked cars not one, and the energy used to wreck each of those cars as per a 50 mph collision is twice the energy it would have taken to wreck one of them. So it is like a 100 mph collision, shared evenly by two cars (so each gets 50 mph worth!)

Lol 1:47 there was a crumb on my screen and I thought yes I can see it

possible impact aversion plan: I really like the general idea of just the slightest diversion of a NEO's course, but none of the examples really popped for me. I've thought much about this, and I think a small fleet of mini-rocket boosters, landed on the surface of some NEO and ignited simultaneously would give just enough oomph to nudge it just enough to avoid us. imagine, instead of a massively expensive rocket ship designed to hopefully travel alongside said NEO and gravity tow it, possibly being lost or crashed and only able to be used once, we instead build a similar ship to get near the NEO and fire a salvo of missle-mounted, cheaply made rocket boosters, designed as cheaply and numerously as possible, to be kicked on at once. having a bunch of them would at least ensure a more ready supply should we miss the first shot, or Einstein forbid, need to defend against the unthinkable more than once.
