The second law of thermodynamics states that the entropy of any isolated system always increases.
The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zeroNot quite, the second law thermodynamics states that when energy change states there is always a little loss to heat( kinetic). The total energy Remains the Same. This results in high energy States eventually being reduced to low energy state, spread out, then the bit about he third law The Logical result is the 'Heat Death'. Look it up.Yes, perpetual motion. Unless we can prove the universe is losing energy to another system, then we have to w it is a closed system. Even if it is not a closed system, then the combined systems must be closed. And if they are not, then they're combined systems must be closed. And on and on it goes.
That was the bit I was talking about cosmetology. Are we in a expanding universe a collapsing or an oscillating universe? If oscillating, collapsing into a singularity, Big Bang again, but we don't know what the Big Bang was. Still looking, don't know. Just don't know what happens in a singularity. Didn't want to use the verb happen, since relative to us t=0 in a singularity.
Man you lost me, enclosed doesnt mean perpetual, it implies uniform. Any closed system given enough time will reach absolute zero.. Third Law thermodynamics.some point, every system is enclosed and everything inside is perpetual. But even if this is not the case – that there is no "enclosure" and that the universe/multi-verse/existential existence is indeed infinite – then the fact there is no beginning and no end also means that whatever it is we are dealing with is perpetual.
Under Einstein's general relativity, space does not exist outside of Mass( 4d with respect to time). what we observe as motion is the change in the manifold from Mass. Okay I'm bad at explaining this. It's non intuitive
Setting aside the motion point, No, Not at absolute zero. Third law. Everything is approaching that point. You know entropy.Everything moves. That is the one constant that we know of. Every single thing in the universe that we think we understand is in motion. But what is "motion"? Is it still a positional reference without time?
Again SpaceTime only exist with Mass. So it's nonsense to think space goes on forever without Mass. It only exists because of mass, I know counterintuitive welcome to special relativity.
Well you don't know. Pi doesn't go on forever, even using floating-point notation, pi approaches a limit, the point on the number line we call pi, you know calculus 101. Pi is not infinite it's a very finite point on the number line. You keep using that word infinite I don't think you know what it means.While Pi can be expressed as a formula, it cannot be expressed as a rational number (as you have mentioned). As far as we know, Pi is infinite – we do not know where it ends – and therefore we cannot measure anything with it because there is no way of knowing if the Pi of one circle is the same Pi as another. It only takes one number in an infinite series of numbers to disprove that C= Pi x D. So we will never know if this is true or not.
Consider this, taken 1 meter length string make a circle, measure/calculate the diameter and it will be a irrational number. Still finite. The diameter doesn't go on forever, it's length is finite, measurable. Jes Another Real number on the number line,
It's like you're not able to think in the set of Real numbers only the subset of Rational numbers. Ya will always get a incomplete view of the universe. For what it's worth so does computer arithmetic. it uses a floating-point notation to simulate the set of Reals. it can only express in integers, cuz it's Intrinsic when expressing a bit stream as a number.
.Energy and matter are proportional. Massless particles, such as photons, are not matter. Yet they still carry energy. If "m" = 0 in E=mc2, then you are still left with the speed of light squared. Velocity = energy
Oops, forgetting algebra 101?
If m=0, then zero times any number no matter how large ( and c squared is big) still equals 0. Thus E=0.
nup velocity does not equal, or imply energy. Cuz velocity is not in the equation!
Ummmm. C squared, is not a reference to Velocity or speed, it's jes a number, a constant. Derived from measuring the speed of light. Meters per second
I bet acceleration is what you're thinking of. Meters per second per second.
F=MA. Force equals mass times acceleration.
it takes a Force to move Mass faster, acceleration; intuitive. Zero Force to keep an object just moving, speed.
Ah, much as I'd like to debate this all night (not really), I've got shit to do and smoke and go to bed. So . . .
E=mc2 = My Bad. The full equation is E2=m2c4+p2c2. For resting mass the equation is E=mc2. For massless particles (ie: photons) it is E= pc. I can't remember the point I was making
Perhaps it was something along the lines of nothing can exist without mass or energy, so there will always be one or the other in a system (see below).
You may assume entropy will end all motion in the universe. But that relies on the universe neither expanding – which it is, at an accelarted rate – nor contracting – which we may never know, but is the theory behind the Big Crunch, as I'm sure you know.
In that respect, my argument is based on the fact we are simply here – there is "stuff" – and that whatever this existence is, it must be perpetual. Or we wouldn't be here. And I think you agree with me on that.
I understand that at Absolute Zero (kelvin) things stop moving. But Absolute Zero can never be reached: unless the universe was infinitely large (entropy) and infinitely old (entropy again). No closed system will reach absolute zero – no matter how long it takes.
I know what infinite means. If Pi does not have an infinite number of decimal places – and admittedly we will never know if it does or does not (which is my point) – then you would be able to say with certainty what it is. But then, it's a bit like a piece of string – we can never exactly measure it. It will always be rounded.
