Have 1 cc of this stuff on your ship near a neutron star, even at 1g, there's a force of 29400 billion newtons acting on a 1cm2 area. I imagine it falls right down. Use your imagination for the rest.

I would use my understanding of multidimensional space to create a conduit between the bubble this universe resides in, and a bubble with a higher base energy level; this should give me the power to do what I need, and have the added benefit of delaying the heat death of this universe.

Loinburger, you didn't say anything about destroying the sun or other planets, so I went for the surgical option.

In this case, procrastination is your friend. Wait 10 billion years and your work will be done for you.

You could also explode two huge nuclear weapons at opposite ends of the Earth, thereby knocking the Earth out of it's orbit and straight into the sun. But that requires actually doing work.

To alter the moon orbital velocity enough to hit the earth you would need billions of tons of tnt, and of course off center, not in the core, (which I doubt we could get to anyway). An the Moon hit the earth would not cause it to crash into the Sun or otherwise marterially alter its orbit. The Earth moon Pair is orbitng the sun, adjusting the part of the moon velocity that orbits earth will still leave most of the orbital velocity of the pair around the sun.

If you detonate enough nukes/TNT/etc. on the part of the earth which is pointing in the direction of the earth's velocity, you could concievably take away all of its kinetic energy, causing it to fall into the sun. You'd need an insanely strong impulse to be able to do that, though. I doubt we could currently pull it off.

Causing the moon's orbit to fail might be another good way. Hell! Its all good when it comes to blowing this piece of s*** planet up.

The earth's core is 90% nickle and iron which can be proved by examining the why seismic waves bend or shift as they travel from a less dense medium to a denser medium. Of course the outer core is liquid and the inner core is solid so it is hard to get direct data (things are easy to calculate how the wave travels when you go from a less dense to a more dense but once you go from rock to liquid to solid metal back to liquid and finally back to rock then things get complicated ) but it can still be done indirectly. Also we'd have to have a solid metal core or else there would be no magnetic field around the earth.

BTW the Earth is no where near massive enough to generate fission or fussion. Jupiter is far to small so the Earth is way out of the question.

quote: Originally posted by Lancer Thanks for the reply Oerdin. So the spin of the other planets is on a plane w/ the solar system? Would they never have been tilted by other bodies? I was thinking that the force that gets all planets' spin into the plane of the solar system might be magnetism. Any chance that the sun's magnetic field might be the force which alters the 'object in motion' to bring them into line? Also, will the earth ever flip flop because the spin wobbles or is that just bad sci fi?

If I remember correctly all of the planets except Pluto (which is really just an over grown asteroid and not a planet) orbit the sun with in a few degrees of the ecliptic (the imaginary line which extends from the equator of the sun). All of their orbits are slightly eccentric, meaning shaped like an eclipse, with the sun being one of the focus points for the eclipse. Again Pluto is the exception because its orbit is very eccentric and resembles the orbit of an asteroid more then the orbit of a planet.
At small scales where matter is close together Magnetism is the driving force, however, with the large size of planets and the vast distances of space the strength of gravity is millions of times stronger then the magnetic force. So magnetism isn't going to play an important part in determining how planets rotate in their orbit or how fast they spin on their axises.

I'm trying to remember back to my old college physics class and I recall that if you have a large cloud that is moving ever so slightly then once gravity collapses it down into solid bodies the small force vectors get added together and multiplied by the square of the distance between the two particles (some one who's taken physics in the last 8 years please double check this and tell us the real equation). In any event the slight motions of a very spread out body will become much faster motions in a very dense body and that is why the planets are spinning and rotating so quickly.

The largest body in the solar system is the sun so all of the smaller bodies will want to rotate with their axis parallel to the suns axis. Some are a few degrees off (1-3) due to be smacked by large objects and I think Neptune is way off (like 90 degrees off) because it got hit by a large planet sized object during its early history.

Simple, an easy 5 steps (This isn't original but it should work*):

1. Build 2 teleportation chambers, a sending and a receiving chamber. Position the chambers in a vacuum (the size of a large warehouse, perhaps), so that the sending chamber is directly below the receiving chamber.

2. Place some powdered silica, or iron, in the sending chamber, and teleport it into the receiving chamber. Leave the sending chamber switch turned 'on'. The silica will then fall down into the sending chamber and, before hitting bottom, be teleported up to the receiving chamber, only to fall back down and be teleported up again ad infinitum.

3. Wait a while. In a vacuum, with no air resistance, the endlessly falling silica should eventually get close to lightspeed. As time passes, general relativity theory suggests that when the speed can no longer increase, the mass will increase, eventually to an infinite mass.

4. Now, really fast, move the sending chamber out from under the receiving chamber (Or just turn it off). The falling powder will strike the earth at near-lightspeed, with an infinite (or at least, pretty big) mass.

5. Kaboom.

Well, it could be a neutron made of the opposite quarks, ie anti-up and two anti-down quarks. I don't think it would be any different, but I guess it would anhilate any regular neutron upon contact.

Well, your premise is true, but your justification doesn't quite make sense. As a consequence of Newton's laws, the magnitude of the angular momentum of a body under a central force is constant. That means if the radius of a body's orbit decreases, it's angular velocity increases. So, when gravity collapses the cloud of gas into a planet, due to conservation angular momentum, the anguar velocity of the planet increases.

An anti-particle has opposite values for all quantum numbers of a particle. Charge is only represtented by one quantum number.

What you're describing is the conservation of angular momentum.

Given a central force (like gravity exerted by a non-moving spherical mass) the angular momentum of the system about the center of this mass is conserved (this is a direct result of F=ma)

Angular momentum of a point particle about the origin is l=rXp where r is the distance vector from the origin, p is the momentum vector of the particle and X is the vector cross-product.

The upshot is that for angular momentum to be conserved as a body contracts, the velocity of its surface must increase in direct proportion to the decrease of radius. Its angular velocity therefore increases as the square of the shrinkage.
