Re: We now have a planet named Sedna

well... it cant a happen - absolute zero is the point at which all atomic vibration stops - so once its stopped, it cant stop any further

so by definition it cant get any colder

(and by the way, you cant have windchill at 4K - I think all the gasses we know of would be a liquid at that temp, and most would be a solid, there there cant be any wind :^)

Well, this is a FIRST robotics forum so I think it's safe to say we're not talking to anymore lawyers...

4k is pretty cold. Sounds like Michigan weather to me!

Re: We now have a planet named Sedna

I have a bit of trouble calling Pluto a planet. I've always defined a moon as something that orbits a planet. Pluto is odd because its moon, Charon, and itself orbit each other. Since Charon is smaller in size I consider Pluto a planet. Sedna is extremely small, and we aren't sure if it is orbiting something else or not. For all we know there's something out there that eats planets like Jupiter for breakfast.

Yeah, like all molecular movement in the entire universe stops...

Nothing can ever be absolute 0, because that means it's not getting bumped by radiation from nearby jiggling molecules, which means that they're not moving (cuz if they were moving, they'd be makin' radiation), which means that they're not getting bumped by nearby jiggling molecules, which means that they're not getting bumped by nearby jiggling molecules, which means that they're not getting bumped by nearby jiggling molecules, which means that they're not getting bumped by nearby jiggling molecules, which means that they're not getting bumped by nearby jiggling molecules, which means that they're not getting bumped by nearby jiggling molecules, which means that they're not getting bumped by nearby jiggling molecules, which means that they're not getting bumped by nearby jiggling molecules, and so on and so on.

Re: We now have a planet named Sedna

the laws of physics dont agree with your concept - energy disperses and eventaully all matter will reach absolute zero and the universe will enter a state called 'heat death'

and since the universe is expanding at an increasing rate, that means it will never collaspe back in on itself

in otherwords, the universe as we know it had a beginning, and it will have an end -> zero K.

Energy disperses? Since when? Where does it go to? Ever heard of the Law of the Conservation of Energy?

Has that been determined? Or have they just determined that they haven't determined anything? And what would be causing the acceleration? What would be pushing us away from everything else? Anti-gravitons? No. There are two theories for The End Of The Universe. One is the Big Void, where everything gets really far apart from everything else forever and ever, or the Big Crunch, where everything crunches back together. Kind of like this:
You throw a ball up into the air. The act of throwing it up can be compared to the Big Bang. Now, there's very little evidence to show that the ball will continue accelerating up forever. What usually happens (since the last time I checked) is that the ball comes back down and crunches (Big Crunch) onto the ground.

The beginning of the universe didn't have a temperature, because there was nothing to measure. It just wasn't. And when it was, it was billions upon billions upon billions of degrees C, because of all the energy packed into that infinitessimally small point.

I apologize if I appear snide.

Re: We now have a planet named Sedna

ok, now that I think of it, you are right - matter and energy cannot be created or destroyed, so the level of enegy in the matter of the universe will eventully reach an equilibrium - where everything is at the same energy level or temperature

but after giving this some thought, I guess the universe cant level out to absolute zero - but it will probabally be close.

All the obeservations that have been made show the universe is expanding at a speed greater then its relative escape velocity - so it will continue to expand forever

and recently scientists were all in a flutter because the expansion has been measured as increasing - the galaxies are accelerating AWAY from each other faster and faster - which we cannot explain with observable physics - they only explaination they have been able to come up with it the phantom 'dark matter' which has anti-gravity properties.

The more you learn about quantum and astrophysics, the more it disturbs you - its as if the universe is only a simulation in the mind of God- its too bizzare to be real :^)

The only reason that happens is because all planet/moon systems orbit around a center of gravity, not the planet itself (in fact, anything with mass acts this way). Both Pluto and Charon are close to each other in size (I think Charon is half the size. Proportionallly to its mother planet, it's the largest moon in the solar system). So the CoG of the system is about a third of the way out of Pluto towards Charon. That's what it orbits. It's the same with Earth and our moon (I believe we orbit around a CoG that's about at the surface of the Equator). And don't get me started about the sun and every rock going around it.
