Is it possible that life can survive on Earth after an impact with an asteroid or comet the size of Hawaii???

Question

If so what would happen to Earth,what it look like to us before it hit and would life start over,in a diffrent,yet similar way???...Tom Science 4

Answer 1

I'm sure it would send a powerful cloud of dust the likes of which would block out the sun for years killing all vegetation.. like a domino effect we would all die from lack of oxygen, water, food, etc. can you say dinosaur extinction?

Answer 2

you have a sturdy factor "IF" an incoming asteroid would desire to truly be thoroughly blown-up. yet i don't think of you extremely comprehend the masses and speeds that we are dealing with. So start up thinking that what's coming at us is somewhat huge and truthfully speedy and consider right here: a million) we don't have an explosive device able to thoroughly blowing or obliterating an merchandise the dimensions of a small mountain. The technologies would not exist. Even the 50 mT hydrogen bomb detonated via the Russians in 1961 would not be waiting to do the interest. With our contemporary technologies it somewhat is it sorta like attempting to break an on-coming bullet practice with a basic better half and young little ones hammer. 2) evaluate for a 2d the that the technologies did exist to explode a a million kilometer mass into 30 smaller the two sized plenty sort of say 30 - 33 meters somewhat. each and each bit could make it to earth with right here potential output. Given the mass of a 30-meter extensive rock to be approximately 3000 kg in line with cubic meter, we would desire to calculate the quantity of the rock and multiply cases this density. for this reason we've m = (4/3) PI R^3 (3000 kg/m^3) = (4/3) PI (15 m)^3 (3000) = 4.2 x 10^7 kg. for this reason the completed potential is, E=a million/2 (4.2 x 10^7 kg) (a million.5 x 10^4 m/s)^2 = 4.8 x 10^15 joules. To be secure, enable's think of that 0.5 the kinetic potential is lost to noise, slowing, and fragmentation of the meteoroid in the previous it explodes. that still leaves approximately 2 x 10^15 joules for the explosion, while in comparison with approximately 3 x 10^13 joules for the Hiroshima A-bomb. Yielding and predicted explosive potential, sort of, on order of 60 A-bombs, or 500 KT of TNT. It became closer in result to an exceedingly super H-bomb. for each Fragment! it somewhat is 30 Tunguska sort activities on earth at as quickly as! finally, evaluate for a 2d that the object have been an merchandise like comet Shoemaker-Levy 9 sending 9, a million kilometer sized gadgets streaming into the earth. pondering our previous calculations, it somewhat is 270 Tunguska like activities distributed everywhere in the earth at as quickly as. sure, the single huge damaging adventure is stopped however the distributed destruction continues to be sufficient to annihilate mankind. so which you spot it makes so lots extra experience to strengthen set up-able deflection technologies now extremely than waiting till it somewhat is basically too overdue.

Answer 3

Don't worry about it. Not going to happen in our lifetime. Gama bursts from exploding or imploding stars or black holes are more likely and you won't even know it happened until its too late, We are in the beginning of the next ice age as the ocean levels are dropping and the pole caps are melting. That means more moisture in the air thus blocking out the sun and cooling the earth. Get ready to move to a warmer climate near the equator.

Answer 4

where has it hit, the poles would enable some life to exsist but i doubt wether human life would survive an impact of that size.
it could knock the earth of its rotational axis,then all life would cease.
some would see it coming some would not dependant on your location on earth at night it may appear like a shooting star or comet.
the probabilities are endless. LF

Answer 5

Yes. Such an impact would, no doubt, destroy much of life on earth. But the possibility of destroying all of the human race is very small.

Answer 6

Absolutely NOT.. the only thing that would survive would be ants and cockroaches and they survive anything

Answer 7

black-beetle can survive nuclear war

Answer 8

Yes, but don't worry that fear has been around for centuries.
