Ummm no pressure shockwave since there is little medium for it but surely an energy shockwave of some sort. Yes?

yes there is heat (but hardly a "shockwave" since that requires a medium) but that won't "shunt" asteroids, that's hollywood

There has to be something. After all, solar sails have been postulated based on solar energy. There is energy released from an atomic explosion other than heat and physical blast.
There has to be a nuclear physicist here on this board! Beuler! Beuler!

Assuming a perfectly spherical explosion, the explosion will send out both energy and matter in all directions. Both energy and moving matter has momentum, which when it hits the asteroid will be transfered to the asteroid. The asteroid will then be moving away from the source of the explosion.

When I was talking about debris from the asteroids hitting Black Star, I was thinking more along the lines of the remains of the asteroids the nukes were actually placed on, rather thant he blast shunting other asteroids around

the solar "wind" isn't a type of shockwave, the force involved is miniscule, no shunting
it is quite simple, in space you will not get a nuclear shockwave because there is no medium to be displaced

Look up the old Orion project. It was a space ship designed in the 60's that used small nukes for propulsion.

Sorry Pengquin But Im gonna have to raise the flag on you here. One The asteriods would move. When you peak of a medium Space is the medium. We as a race can speak to our satlellites and astronaughts in space can we not? That is done with radio waves which yes move in a wave form. I could go into the super technical format here but for the sake of not blowing some peoples brains up I wont. Anyway, IF a radio signal moves in space on a carrier wave of energy. IF there was no medium in space we'd never be able to talk to our spacecraft. Now back to the original question. Would Those asteriods move, Yes On sheer energy waves (remember Radio Frequency is energy) they would move. >m+E+Direction=Movement (Ive simplified this equagion for purposes of understanding) An energy blast wave along with an electromagnetic pulse wave would radiate from the center of said nuclear explosion and yes a Nuke explosion will create a tremendous amount of energy, and with it all bottled up in one slamm plase it will expand thus creating a blast wave of energy.

Or alternatively the radiation superheats one side of the asteroid, which tries to expand or vaporises, pushing the colder side away.

But radio can travel through a vaccuum, pressure cannot....
I've seen countless scientists say that you cannot use a nuke blast to shunt asteroids. You can as cheesyrobman says heat one side, which would work wonders on comets but for asteroids you either shatter them or hit them with enough force on impact to divert
Hollywood has a lot to answer for....
A shockwave does not consist solely of pressure variations. Matter of fact, the pressure variations are the RESULT of the shockwave moving through a dense medium.
In space, no, no huge pressure variations until the shockwave hits something. Like a ship. Sudden, massive pressure on the impact site as compared to anywhere else. Just like with any other impact.
With a nuke, you still get a massive explosion and Huge amounts of released energy. Energy+motion=force. Anything hits by the explosion is going to have an outside force (the explosion) acting on it to push that object in the same direction.
Either you are reading some really shoddy scientists (Global Warming, anybody?) or you are taking what they say out of context.

Nuke goes off next to an asteroid. Side of asteroid closest to nuke is hit by EM radiation and matter from the nuke. That asteroid is therefore experiencing pressure on the side closest to the nuke.
Note that pressure is merely force per area. If something is experiancing a force to a given area, it's experiencing pressure.

What happens when you detonate a nuclear warhead near an asteroid rather depends on the nature of said asteroid. 
Some asteroids - including the types that produce iron and stony-iron meteorites on Earth - are thought to be solid; they might respond by having their vector changed - albeit not by much - as the surface facing the burst is vapourised and produces a brief pulse of gas pressure.
Other asteroids - possibly cometary remnants that have lost their volatiles - are thought to consist of loose piles of, basically, gravel, barely held together by their own weak gravity. Such objects might simply absorb the shock heating by collapsing in on themselves - a bit like punching a beanbag - or might drift apart into fragments.
Since no-one has tried it yet, no-one knows for certain.
In my experience, the real-world debate on the use of nuclear weapons to deflect Earth-crossing asteroids is heavily coloured by the political views of the scientists and other commentators...on *both* sides.
