Comet hitting the E-D (with shields up)
 
I remember once my friends were telling me I knew nothing about Star Trek, because a comet could not destroy the E-D with it's shields up (or down!) but if this is correct

http://en.wikipedia.org/wiki/Antimatter

and since photon torpedo's contain 1 kg of matter annihilated with a 1 kg of matter, and at least several photon torpedo's can take down and destroy the enterprise (though, we don't know how many) and say in Hale Bopp had hit us, instead of Jupiter, it would have impacted with 44 times the energy of the dino-killer asteroid. Yes, assuming they wouldn't just destroy it with their weapons. I'm talking about it actually hitting the ship with the shields up

I think something is wrong here though, according to wiki (yeah, I know it's wiki) also 1kg of anti matter is much greater than hale bopp-

http://en.wikipedia.org/wiki/Hale_Bopp#After_perihelion

But, obviously hale bopp would hit with a lot more energy than the Tsar Bomb, if the Tsar Bomb did explode with that much energy it would be much greater than the dino asteroid and we wouldn't be here right now. Not a physics expect either, just it lists Tsar as a greater yield which it can't be.

I remember reading about a case where a certain comet was speculated to be made of antimatter due to the way it broke up and dispersed before even completing one orbit around the sun...

One thing to remember about the Hale-Bopp impact is that it was accelerated by Jupiter's gravity. Thus it's only directly applicable if the Ent-D was inside Jupiter's atmosphere at the time.

Y'all are talking about Shoemaker-Levy 9 right? Hale-Bopp didn't hit Jupiter!

1.) Hale-Bopp has been estimated to have an impact energy of about 4.4*10^9 megatons TNT equivalent. That's over 77 million times the power of Tsar Bomba.

2.) 1 kg antimatter undergoing total mass-energy conversion with 1kg matter yields 1.8*10^17 Joules of energy, or about 43 megatons TNT equivalent, about 14 megatons shy of the Tsar Bomba.

At least not yet.... and it'll be at least 4000 years before it gets close enough....

But yeah, some of us(myself included) seem to have confused the two.

Anyways.... The issue here isn't the energy released on impact. It's that Hale-Bopp is estimated to be 35km in diameter. ANYTHING that big hitting the Ent-D would probably destroy it.....

I think your friends were hung up on the ship's Navigational Deflector, the big dish up front, which has a main function other than just being the socket that says "plug in technobabble solution here" overhead. It pushes space debris out of the path of the ship so you don't have Yuri Gagarin's toothbrush ripping a hole through the saucer before you can even break orbit.

Probably wouldn't function on that scale, though. Case in point, "Booby Trap", where they go through quite a lot of trouble not to hit a bunch of relatively slow-moving asteroids. If they're worried about those, they're not going head on with a comet. And definately not by accident. (Honestly admiral, that massive object on a fixed trajectory snuck up on us and threw itself in our path! Now can I have a new ship? I'm thinking sleek with a visible warptrail. And seatbelts.)

Yes, actually, I made a mistake

If Hale-Bopp did hit the Enterprise-D (assuming the Enterprise was travelling at sublight velocity) the comet would barely notice the impact. It would simply continue on its merry way with a Galaxy-class-shaped indentation in the front of it.

Hale-Bopp's nucleus is estimated to be 70km in diameter - roughly 100 times the diameter of the Enterprise-D's saucer section. Sheer mass almost always wins.

And before you start to argue that the Enterprise is denser than an ice ball, let me remind you that any ship mostly contains air. The hull may be more dense than ice, but it's just a thin layer of tritanium and transparent aluminum meant chiefly to contain the air within. Generally whenever a metal ship meets a large ice cube, the ice cube wins. (Remember the Titanic?)
