Thread: Ballistic properties of planetoid sized objects in nebulas.

I'd be pretty interesting to be able to study the effects of a planetoid sized object hurtling through a nebula at a speed great enough to affect the super-low density gaseous body. Especially if it was capable of causing a shockwave in such a body. Of course, thinking realistically, it would probably have to be traveling at near c to be able to impart enough kinetic energy into the surronding low-density matter to create a shockwave.

The average density of an interstellar molecular cloud is about 1000 to 1000000 atoms every cubic centi-meter. Other Inter Stellar Mediums have much lower densitys, but most of these are charged plasmas and so are far hotter than the 10 - 20 k of an IMC. [very close to absolute zero]

It should be noted that very, very little is understood of the properties of the Interstellar medium in general, especially how things such as large organic molecules can be made in the quantities they are at the low tempertures exhbited by the clouds.

It should also be noted that these clouds are rather large, varying from a light year to several thousand light years. Very. Very. Big.

Anywho, it'd be pretty damn interesting.

Most of the people here didn't understand what you just said.

Meh.

They can go and damn well learn then.

yes it would be very interesting study such a thing.

That would be interesting. In fact, so interesting I can't visualize it. =P What do you think would happen, Ish-san?

Sounds like a classic scientist approach. If we don't know what's happening, let's smash something into it and see if anything happens! =D

They're actually doing that with the moon to see what's in the moon. *shudder* I hope they don't do it to the Earth one day. If they haven't already.

I keep seeing things about how they're making BIGGER and BETTER particle accelerators so they can smash those little particles together even HARDER.

the moon and the earth have been hit by enough things traveling at super speed that it would be pointless to attempt to hit it with something else. and anyways. a BILLION tons of matter not originally from earth lands here every day (dont worry its interstellar dust, and a billion tons is not alot), theyve got enough shit to experiment on from that alone.

ishman im interested in your approach since i thought light was the only wave that could travel in the vaccum of space, and why a planetary body would affect a nebula like that when nebulas are billions of times larger than any planet and so incredibly ... thin...

enlighten me!

Interesting Ishman
I wonder if it would effect the nebula to the degree that it's stucrture would alter entirely or only portionally or at all.
