If NASA had the same budget as the US military, that asteroid is gonna vaporize instantly

Even scientist don't know how to stop an asteroid

[deltanogs]

The explosion thing is probably the best idea, just strap a few tons of c4 to a ship and BOOM crisis averted.

Nah Jupiter will take care of it for us

Bombing an asteroid on a collision course with Earth may initially appear to be a straightforward solution, but it is a highly dangerous and potentially catastrophic approach. The explosion would likely fragment the asteroid into numerous smaller pieces, which would continue traveling toward Earth. These fragments, while smaller than the original asteroid, would be drawn into Earth's gravity, spreading out over a vast area and dramatically increasing the number of impact sites. Each piece, hurtling at high velocity, would retain enough kinetic energy to cause significant destruction upon impact. This scenario transforms a singular threat into a widespread, uncontrollable disaster.

Once within Earth's gravitational pull, the fragments would accelerate, hitting the atmosphere with incredible force. This mirrors the effect of a needle falling from space: though small, the sheer speed and focused energy of the impact could penetrate deeply, causing extensive damage. When multiplied across dozens or hundreds of fragments, the devastation would be orders of magnitude greater, with some areas experiencing fires, shockwaves, and cratering effects simultaneously.

Scientific studies and historical models confirm that such an approach would likely worsen the situation, turning a manageable threat into a chaotic and unpredictable crisis. The risks associated with fragmenting the asteroid outweigh any potential benefit of reducing its size. Instead, serious attention should be given to alternative methods, such as deflection via gravitational tractors or kinetic impactors, which aim to alter the asteroid’s trajectory without the catastrophic consequences of fragmentation. Bombing an asteroid is not just a flawed strategy it could transform a single disaster into a planetary-scale calamity.

(if you have any problems with my perspective, whats your solution then?)

Energy Required
The energy required to change the asteroid’s trajectory significantly would be enormous. The kinetic energy of an 11 km asteroid moving at 20 km/s would be on the order of 10^15 to 10^16 joules, depending on its density and composition. To put that into perspective, this is roughly the energy of several billion tons of TNT, which is far beyond the capacity of conventional explosives. Even a powerful bomb, like a nuclear warhead, would not come close to generating enough force to alter the asteroid's path in any meaningful way without catastrophic fragmentation.

Risk of Fragmentation
As mentioned earlier, the explosion could cause the asteroid to break into numerous smaller pieces. These smaller fragments, while each individually smaller than the original asteroid, would still be traveling at high speeds (20 km/s or more). Once the asteroid fragments, these pieces would be drawn into Earth's gravity and could cause widespread destruction upon impact. Rather than mitigating the threat, the explosion would multiply the number of objects that could impact the planet.

Impact Speed and Destruction
At a speed of 20 km/s, the asteroid or its fragments would strike the atmosphere at hypersonic speeds. The kinetic energy of each fragment would be immense, creating heat and shockwaves that could ignite fires, cause global devastation, and potentially trigger a mass extinction event, much like what is thought to have happened with the asteroid that killed the dinosaurs. Even small fragments, moving at such high speeds, would deliver catastrophic energy on impact.

Difficulty in Directing the Explosion
Given the massive size and speed of the asteroid, targeting a specific point on it with enough precision to alter its course effectively is highly difficult. The asteroid could have an irregular shape, and its spin could make timing the explosion even more complex. If the explosion occurs at the wrong angle or at the wrong time, it could impart a glancing blow that wouldn't have the desired effect, or worse, cause the asteroid to fragment in an unpredictable way.

Alternative Methods
At this scale, more controlled methods would likely be required. For an 11 km asteroid, alternatives such as kinetic impactors, nuclear deflection (detonating a nuclear device near, but not on, the asteroid to use radiation pressure or a small explosion to nudge it), or a gravity tractor (which uses the gravitational pull of a spacecraft to slowly alter the asteroid’s course over time) would be safer and more effective strategies. These methods involve more gradual, controlled changes to the asteroid’s trajectory, avoiding fragmentation and offering a more reliable solution.

Conclusion
In the case of an 11 km asteroid traveling at 20 km/s, bombing it with conventional explosives to change its direction would likely be insufficient and extremely risky. The amount of energy needed is far beyond what we can currently produce with existing technology, and the risks of fragmentation would dramatically increase the potential for global destruction. Instead, alternative methods such as using kinetic impactors or nuclear deflection techniques would be more appropriate and effective for dealing with such a massive, fast-moving object.

(Yes I actually wasted half my time typing this all out, but thanks to Grammarly it helped me save a lot of time, and yes, I did think of the scenarios what would happened with the given choices in this video)

Nasa be like:-
No worries bro
I got you!😂

[Averagewetowl]

I’ve only heard about redirecting it with explosions not the other option’s.
Also amazing edit skills, 60K subs is in reach u got it!

[florxfr]

we can wrap it with foil letting it move on its own but this theory hasn’t been tested yet

[TheoTagE_]

What is your editing app? and did you use blender for the annimation?

[goofygooberbobux]

well, with some intense calculations and difficult and costly manuevers, we might be able to send a ship with a probe core into the surface of the asteroid, possibly deflecting or reducing its velocity enough to change its orbit

(yes i play ksp 2)

[iHaveNoEnemes_RB]

I call that Plan APOS(Apocalyptic Plan Of Survival)

[movieking]

Bro just paint one side with silver white colour so it will deflect sun rays and it's direction changed. Now don't ask hiw to paint it 😅

[use_your_brain_pls]

Doesn’t have doesn’t even have to be that big for an explosion just enough to take it off the course of the earth

[SimplySalvadoran]

You could try to make a nuke and aim it to the asteroid and shoot or you could send a satellite and directly point it at the asteroid until the satellite collides with the asteroid and changes its x scale and y scale and its orbit

[Bharat_MappingEditz]

THIS IS THE BEST SPACE EDIT I'VE EVER SEEN FIRE BRO 🔥🔥🔥🔥

[Gamma_TM]

I don't think we can do anything if it's coming directly at us

[lastbreathnova]

The asteroid cant surpass the earth's gravitational pull lets say if it does its probably going to fail
