makaveli is kinda right, gravity travels at the speed of light.

I thought gravity was a magnetic wave, making it slower because it isn't a light wave...Comment

Gravity doesn't travel as a speed does it? It's just the pull of a massive object, the bigger something is, the more pull it has on things, and the closer you get to the large object, the faster you travel because you are being sucked into it's pull.... So gravity doesn't really travel, more or less, it's just a natural thing that's always there until you break free by going massive amounts of speed in the opposite direction. And gravity isn't caused by magnetic waves or pulses or whatever either is it? Cause if it was, one, computers wouldn't work at all, two, all metal objects would be stuck to the ground, and three, we would fly off the planet seeing how there is no metal at all in us. That's proven by catskans, if you go and get one and we did have metal in us we'd be ripped apart.Originally posted by VxDxComment

Wow cool,I'd like to see tha happen. Anyways enough with this mumbo jumbo :P
I can believe that there immumerable worlds/dimensions/planets and such. Why not believe it?Comment

Gravity has speed.
Thus gravity waves, in space....

Explain these "gravity waves". Though, I was more talking along the lines of gravity on planets, what are these? Is it like when a Red Giant implodes creating a black hole and it's the speed of which the black holes gravity reaches a physical object to pull into it?Comment

Nice try, a red giant implodes into a blue giant....

I'll see if I can find a link to a website about it...
that's the site, but this pretty much sums it up...
The electromagnetic field can have waves in it that carry energy and that we call light. Likewise, the gravitational field can have waves that carry energy and are called gravitational waves. These may be thought of as ripples in the curvature of spacetime that travel at the speed of light.Comment

One theory about black holes are that when a star implodes, all it's mass is compressed until there is no longer any space between particles. Thus creating an object with such immense weight, that it actually bends the matter around it causing a sort of "pocket in space" (some how gravity is mixed into the equation). The gravity produced by the black hole is so great that not even light can escape it.
I dont know all the facts, but it was something along those lines.

Really? Cause I thought that it was mainly dependant on the size of the star when it explodes or implodes. So different paths can be taken, some don't reach Red Giant, but what was it that sometimes takes the path of a black hole?Originally posted by QreepyBORIS
And VxDx, grade 8 cirriculum, I'm not smart enough to understand what the hell any of that site. I can grasp a couple sentences...If I try I could probably come up with more, but I don't want to have to think that hard about what I'm reading. (Hence the lazy factor)Comment

It's blue giants that turn into supernovas/neutron stars, typically.

Originally posted by QreepyBORISThe Protostar Stage:
A giant star will start its life out, like so many other stars, as a protostar. The difference is that a protostar that will eventually form a giant star starts 100 times larger in diameter than the Sun (approx. 139 000 000 km or 86 000 000 miles) and at least 3 times the mass of the Sun (approx. 2 x 1030 kg or 6 x 1027 tons). It contracts in on itself due to the gravity created by its enormous mass, and quickly heats up. In a matter of a few thousand years, the protostar becomes a Blue Giant. Nuclear fusion starts in the core at 7 000 000 K, creating isotopes of Hydrogen (see the advanced Proton-Proton fusion reactions page for a more technical look at the first fusion process). The outer layer of the star is already heated to 3000 K and will become warmer.
The Blue Giant Stage:
The giant star has now contracted to only 6 times the diameter of our Sun (approx. 8 000 000 km or 5 000 000 miles), their surface temperature is now over 4 times hotter than that of the Sun, 23 000 K, and this is only a temporary position! A blue giant will last for a maximum of 100 million years, during which it will fuse its Hydrogen into Helium at a speed of over 20 trillion tons per second, that's more than 16 000 times faster than the Sun! The amount of heat produced by this rate of reactions is enormous! The star now definitely appears a blue-white colour, and doesn't belong to the line of main-sequence stars, but rather to the upper right corner of the Hertzprung-Russell Diagram. As more Helium is produced, fusion slows down in the core, allowing it to be compressed by gravity. This compression actually increases the core temperature, causing the expansion of the outer Hydrogen layers of the star. The star doubles in size, the outer layers cool, and it starts another stage.
The Red Giant Stage:
The blue giant has now expanded to a red giant, and continues to expand as the core is compressed more. Not very many interesting things going on at this time. The core temperature steadily increases to 100 000 000 K as it continues to grow into the next stage.
The Supergiant Stage:
The Helium core of the red giant continues to contract, and during that contraction it ignites a couple shells of Hydrogen around the core when the temperatures reach 10 000 000 K. This new layer of fusion, and the heat created by it, accelerates the expansion of the star to the supergiant stage. The supergiant is back to 100 times the size of the sun (see above) and will continue to grow! When compression of the Helium core raises the temperature to 100 000 000 K, the Helium contained in it begins to fuse together into Carbon. This new addition to the fusion reactions in the core of the star balloons its size to over 300 times the diameter of the Sun (over 420 000 000 km or 260 000 000 miles)! The giant's mass will continue to compress its core, starting new fusion reactions, eventually leading to the creation of an Iron core. To see the advanced reactions, click here. The Iron core will not compress to fuse into other elements, because of Iron's atomic structure. Iron has one of the most efficient structure of all elements, therefore making it very difficult to undergo fusion. Iron does undergo fusion, but not at the temperature found inside of any star, no matter how large the star is!Comment

This is pertaining the first few pages. (Sorry, but I normally try to avoid the popular posts since they normally turn into flame wars.)
Isn't it possible that because of the conditions of Earth, we need certain substances, molecules, and whatnot present to habitate life. But on a planet with completely different condions, life would need to use other types of substances, molecules, and whatnot to provide for a specific type of lifeform that is suited to live with those kinds of conditions. We may not be able to "make" these types of creatures, but that is because of the environmental conditions of Earth. The organisms may die/explode when exposed to oxygen, a certain amount of gravity, a certain amount of air pressure, or maybe even a specific humidity level, so they would not be able to be created on Earth or observed on Earth. Life on Earth may require water, but maybe the life on the other planet uses something completely different...although I don't know what it would use, I don't really feel like going too deep into this stuff since it was already debated.
Infinity/infinity would equal 1, since anything divided by itself is 1, for example 12/12=1 just like 10000/10000=1 or even googleplex/googleplex=1...right?\"A single death is a tragedy, a million is a statistic.\"

In that post you have brought one new fact to our attention. Infinity divided by infinity could not eequal one seeing how infinity is everlasting and goes on forever, therefore, in order to KNOW that infinity divided by infinity equals one is by giving it a numerical value likeOriginally posted by jpyb007
67, 3456, 3478, 9562, 3789, 4562, 7895, 6347, 8956, 7863, 4789, 5623, 4789
Therefore it defeats it's own definition, because infinity goes on forever. In fact, infinity divided by infinity could equal something like -5. I forget the theory, but it states that there are different levels of infinity. Like, there are moer decimal places between 1 and 2 then there are positive numbers between 1 and a billion. Therefore, between 1 and 2 there is one type of infinity and between one and god knows what there is another level of infinity. Thus making infinity divided my infinity able to equal anything.Comment
