technically no. Since absolute zero is the absolute point at which nothing moves. Which is impossible. The depths of space do get close to it, but particles can still move.

The average temperature of the universe is 2.73 Kelvin, calculated from background radiation, but like I said, deep space itself is somewhere close to absolute zero. I don't think voyager is quite at that point yet.

And yeah, It's impossible to reach absolute zero (much like it's impossible to reach the speed of light)

. Neither are impossible we just havnt found a way to do it yet

FTL travel is impossible, as it would take an infinite amount of energy to do such. (actually, someone posted in the freebie for Bioshock Infinite)

the equation for E=MC^2 is incomplete, and only describes an object not in motion. the actual equation is E^2=(MC^2)^2+(PC^2)^2

you can use the Pythagorean theorem to solve it.

and what you find out in doing such, is that ANYTHING with mass, cannot reach the speed of light. (the particles we have found that exceed the speed of light are functioning on a totally different level, and from what I understand, are massless objects)

The same problem goes for reaching absolute zero. No matter how hard you try, you can never make a particle stop 100%. you can get infinitely close to it, but never reach it. no matter what, there will always be a 1 at the end of that infinitely long string of 0's

http://www.youtube.com/watch?feature=player_embedded&v=NnMIhxWRGNw#!

there's the cool video explaining the equation.

The video states only 5 systems(Lets assume that wiki is up to date) are operational and according to this 17/01/2012 article they turned off the heater

They also said we couldn't fly, Or clone people or make Bionic arms, Or robots or a variety of other things and we've done those, Only time will tell.

Pretty much everything that has been said impossible has been done.

Breaking the laws of thermodynamics is not one of those things (in regard to absolute zero)

And the infinite energy required to get near (but never exceeding) light speed, means that no matter what, we could be going 99.999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999% the speed of light. But there's always going to be that extra tick keeping us from ever reaching it. Not only that, but as you get closer to the speed of light, your mass increases exponentially.

Think of it almost like drag on earth. the faster you go, the more power it takes to overcome that air drag. And as you increase speed, you increase the power required (at a very high rate) to go that speed.

Let's say you have a car, that will do 100mph with 100hp. At 200mph, that same car, would require 650hp, and to go faster than 200mph, let's say, 250mph, that same car, would take another 650hp (making 1300hp)
that's a very bad analogy in some ways, but simply put, the laws of physics and other crap like that make traveling at the speed of light impossible, since the amount of energy required to push that little tick faster, is infinite. you will get increasingly closer to it, but if you have ANY mass, you can never reach it.


Everything they said was impossible was said they were impossible before being proven that they are in fact, impossible.

Regarding absolute zero and the speed of light, they have already proven they are impossible to reach (and especially exceed)

There is a difference between saying something is impossible without proving it isn't possible, and saying something isn't possible because it was proven to be impossible.

very old tech ;p

not very surprising to me, devices used to operate in space without rechangable power is designed to run very slowly very very slowly and efficiently.

much liek the mars rover etc, those things move like slower than a snail.

when you design something to run off nothing, than even solar panels far beyond pluto will still continue to collect energy, just you cannot sustain energy usage. it would be used to fill a reserve to be used at a later time when the energy is actually available.
