I think i guess,,,suggesting that all Nuke rocket weaponry in the arsenal of any nation with Nuke,,,must reserved the Nuke in retaliation in outer space the Neo near earth object to be exploded thru the hit of nuclear rockets.
4:11 this looks like the pollution that the Americans have put into space…..!
Man I was born in 1991and and I sawed one of the old ones and I was like mind dinosaur asteroid
Thanks for that. I think …
The tenuous kohlrabi fundamentally spoil because capricorn inexplicably drip around a inconclusive gemini. tested, abject astronomy
I know how to deflect an asteroid but I'm not going to tell because I want to see the world burn
I think (correct me if I am wrong) the size of meteoroid represented in 3d is wrong
14:25 goodluck sleeping tonight xD
omg funny numbr vies!!!!1!11! 😂😂😂🤣
1:17 looks like a giant peanut….
The asteroid to worry about is the one that extincts the planet and kills your face
God repeatedly has warned us to be prepared as we know not the moment of our death! In todays world of deceit spiritual preparedness should be in focus for us all! Blessings to all!
Super👏👏👏👏👌👌👌👌👌👌
This speaker is great…
69million veiws hmmmmmmmmmmmmm
The author clearly does not believe in creation.
great video
I really enjoyed that 👍
So ideally we nuke it not too long before it impacts earth, so it will have split apart but gravity will not have pulled it back together. Thereby all the large chunks will have much more surface area, and the chances of pieces burning up in the atmosphere will be much greater, thus reducing the total impact of the meteor.
Right?
Granted, it's super risky cause if the bomb malfunctions for ANY reason we'd be dead before we could deploy another rocket. But it's gotta be better than no solution, right?
This scientist is the coolest guy! Love the T Rex in his garden.
So what would happen if a 100 m asteroid hit in the middle of the Atlantic Ocean?
Instead of trying to destroy the object, we could explode a part of it so the damage is reduced,and the rocket we throw at it will slightly change its motion.
they said they actually landed on one and took samples of its composition but they can't tell you when its gonna hit but its good to know what it's made of though.
Dont worry guys that astiroid wil land Putins house nothing to worry ok
Very Informative👏👏.. could listen to him all day
What about the wormwood prophecy ? Nasa says it will hit the earth April 13 2029 and even knows where it will impact the earth.. check it out! It's so big we can not destroy it. VERY CONCERNING…
0:25 How come nobody notice.
HUMANITY IS THE GREATEST THREAT TO ALL LIFE, NOT JUST ON EARTH.
69m veiws
i wish it gets to 69,420,000 veiws
