A huge rock is headed straight for earth

We wrap a tarp around it with a space craft
Fill the tarp with a heavy gas
Once the pressure is high enough inside the tarp
We turn on rockets compressing the gass as much as possable on one side of the tarp
Then we blow up a nuke
Changing the course of the rock enough not to kill everyone on earth

Now you tell me how im wrong and feel better about the world

That tarp sounds incredibly hard to build.
I think all we could really do is just launch a shit load of nukes at it and just take a few hard punches.
I think we could send up just a swarm at one time. The smaller ones could form most of a sphere around the asteroid, then one big one headed straight for it.
The big one would shatter the asteroid, then a split second later all the other nukes around it could go off, colliding with the big pieces and hopefully crushing them in the implosion.
You would have to make sure you had enough collective explosion to overcome the force of the main nuke in a dramatic way though

A tarp? Really? You want to build a giant space condom capable of holding in a nuclear orgasm? Have you given any thought to the mass and tensile strength required for this sheepskin? Obviously not, let alone imagine how much more effectively that mass could be used, like, say, I dunno, MORE DAMN PLUTONIUM.

Good job, Joseph, you earned your corner.

But what if we painted or coated the rock in a dark substance to lower the albedo? Would the increased thermal absorption thus make a nuke more effective via the Yarkovsky effect + radiation pressure?

What if we painted it white?

Just throwing ideas out here. I've always wondered if albedo would magnify or inhibit effectiveness of a nuke

"we should shove a rocket up the earth's ass and move it out of the path of the rock."

good idea!
but most humans on this planet would probably end up thinking it would be more easy if every human on this planet shoved their head up their own ass all at the same time
