I don't know alot in science but I am very curious toward it.
My few questions:
-Wich element(s) can't be burned? Why?
-How many types of "-"plosion exist?
-Based on structure of Earth, could we create a planet?
Thank you for your time. 3nodding

Well, -plosions are movements of energy. Since they can only go towards or from the point of the reaction, all you have are EXplosions and IMplosions.
As for creating a planet... we could... perhaps. A big rock is easy enough to make, although a molten core is tricky.

Okay, I'm confused. Are you asking if we could make a full scale planet? Because, ya know, we kind of can't.

Thanks you all.
zz1000zz: Not a full scale like making a planet in one day but with alot of time.

Well the problem is getting it to stay molten. You can through a jawbreaker in the sun and let the rays hit it and melt the core, but take the rays and it becomes solid.

Is it mercury that doesn't burn? Ah. Dx Chemistry was so long ago. Summer is draining Atha of brain cells.

Atharaveda Is it mercury that doesn't burn? Ah. Dx Chemistry was so long ago. Summer is draining Atha of brain cells. mecrury as a element isnt volitile so it is difficult to make it burn, but it can make impurities burn, (as can all metals) Liquid silvery metal. Stable in air and water, un-reactive to acids (except conc nitric) and alkalis. Used in chlorine and NaOH manufacture, street lights, fungicides, electrical apparatus, etc. http://www.sciencelab.com/data/elements/Hg.shtmlbut theoretically and [my] imaginatorally you proably could, but oif you could, itll put napalm out of business.......... question

I can't think of any physical reason why we could not, at some point in the future, make a planet.
But it would be highly impractical. The sheer scale of the task would be daunting.

Are planets formed because a spot of gravity in space attracts and compresses material of a planet? Or does a chunk of rock develop gravity from its weight? Or can both occur?
Because getting a large chunk of iron is easy compared to getting it to have gravity and... work. Choose a star, orbit, not crash into things.
Bloody hell, why do you want a planet anyway? xp

I say we just steal one of Jupiter's moons and put it into a stable orbit around the sun. 3nodding

What do you mean by 'burn'? Do you mean combustion, as in "A chemical reaction between a fuel and oxygen that produces heat (and usually, light)"?

Bloody hell, why do you want a planet anyway? xp I didn't see this question until just now, but since noone else has said anything, I will. Planets are not formed because of some gravity that was already there, but rather by particles/dust/rocks/etc. colliding and sticking together. As they grow larger, their gravitational pull begins to have more force, futher allowing them to grow. Now, many of these wind up never becoming a planet (these are mostly asteroids and such), but it is possible for them to become a planet if the right circumstances are met. That's a really simple explanation that ignores quite a bit, but I think it answers your question.

redem I can't think of any physical reason why we could not, at some point in the future, make a planet. But it would be highly impractical. The sheer scale of the task would be daunting. Meh, just go out into space and start gluing asteroids together. xd Of course, knowing the way humanity tends to bite itself in the collective a**, it would probably wind up crashing into Earth.

That's a really simple explanation that ignores quite a bit, but I think it answers your question. Yes, it does, a bit. Well... What causes the chunks of colliding stuff to stick together? Small amounts of gravity? And if you really were to get a planet sized chunk of rock and compress it with... magnets or something, pretending that it was possible, would it grow to have gravity of its own?
