Integrating arsenic =/= arsenic based.

In this picture, every place lines intersect, there's a carbon atom. In the situation you pointed out, the phosphorous atoms in the phosphate links of the backbone (colored yellow) were replaced with arsenic to make an arsenate backbone. The majority of the molecule is carbon either way. That's what carbon-based means.

First thing that comes to mind was the Gundam 00 GN Drive

Now

Hmmm they really picked they highest probability of Life other than Earth. to land on. Hope we get to see it

Yes, but the chip couldn't transfer the heat very quickly in a vacuum with just its surface area. This is why temperature change is so drastic in the shadows in space, nothing to hold in the heat, which means there is nothing to grab it off the chip either.

To make it simple and easy to understand. Air is a property here on earth, it has this magnificent powers to hold temperature and carry it around. Now the problem is on the moon there is no air, so when you go to turn it on. The processor will heat up in its own little bubble (sort to speak). Even with a typical today's heatsink on it, it would only heat up the heatsink until it reaches max TDP and melts down. Thats my take on it, tho im sure not a single person in this thread knows what would really happen. biggrin.gif

Again: your point is only valid if you're comparing identical amounts of matter, which was not the case originally. Andrew made the assumption that because space is cold, computers would run cold in space/on the moon, which is a completely incorrect assumption. He didn't understand that because there is so little matter, heat exchange would be almost non-existent.

No, it's not incorrect. I'm not saying that temperature is the measure of the entire internal heat that a body possesses. I'm saying that temperature and heat are directly related--which they are, which is why you can calculate the rise in temperature of an object if you know its specific heat capacity and the amount of heat supplied to it. If temperature and heat were not related in that way, then you couldn't do that. The entirely body of calorimetry disagrees.

Yes, the entire internal energy of a body (kinetic + other energy) cannot be expressed only by temperature--but I'm not saying that it can. That still doesn't negate the fact that the previous statement made that temperature and heat are not at all related, which is incorrect--temperature and heat are directly related. Heat is one expression of energy. Temperature is one expression of energy. They may not be equal but they are directly related. dH = m*C*dT.

Glad I wasn't the only one who thought this. We need magnetic monopoles!

*ahem*

I hope they do find life out there so we prove that with the proper chemical compounds can produce life. Seeing how it is formed there could help us be one step closer to creating artificial life here.

Yes, I understand that, but it was not applicable relative to the original post I'm referencing. You took my "temperature is not directly related to heat" out of context. It's not applicable if you don't see the distinction between a compressed gas and the relative vacuum of the moon's atmosphere. You can only relate them if all the other conditions, and thus, all the other variables are the same.

dH = m*C*dT

Simple math, dude. I'm not trying to be condescending here, so don't take this the wrong way. If m is changing, you can't make a valid comparison between dH and dT.

If I have the equation 1*x = 3, then you can figure out x, but it's not the same if I change it to 1*x = 4.

Edit: Further clarification-

Yes. Yes it is. If there is no (practically) matter to transfer heat to, the temperature of that matter does not make ANY difference. That is the point I've been trying to make since the beginning, which is completely correct. You've confuscated this whole thing.

Nope, but common sense tells us that because space is so vast, there's bound to be life out there. Even (more) intelligent lifeforms. Most likely not within our reach though.

But maybe we are within their reach...

Yes... they'd take one look at our planet and turn around.
