thethinkertank Posted June 17, 2019 Share Posted June 17, 2019 (edited) When mass and velocity proceed along an arrow of time, they undergo certain deviations collectively that would render, exclusively, their forward momentum alone coherent to the human conscious. Why is it therefore that entropy and energy play so wide a role in the speed of light, which surely is the ultimate constant in the theory of the coherence of an Arrow of time? This surely means that the light barrier is subject itself to entropy of energy, which must mean that time space curvature depends on energy and the entropy therof.

Between inertial frames of reference, the speed of light is invariant The rest of your post is barely coherent. Link to comment Share on other sites More sharing options...

I'm quoting the theory of the arrow of time, which states that energy undergoing entropy causes the human mind to percieve it as realistic only when viewed forward in time. A second famous example is the playing in reverse of a video, in which case the original footage would appear incomprehensibe. Link to comment Share on other sites More sharing options...

If it's a quote, show the source of it. And show the relevance to the speed of light. Link to comment Share on other sites More sharing options...

For example Hey Arnold viewed forwards would be a cartoon. Reverse the footage and you'd get a bunch of incomprehensibe nonsense.

Energy does not "undergo entropy", for instance. There is also no mention of the speed of light in that link. Link to comment Share on other sites More sharing options...

Well then, I stand corrected on point one As for point two, the speed of light is always incorporated in an entity such as time which is more or less the defining factor in what made the speed of light a major player in the theory of relativity.

Yes, relativity is based on c being invariant. I'm not seeing the connection with entropy — the arrow of time is a distinct concept from e.g. time dilation.

Sensei Posted June 17, 2019 Share Posted June 17, 2019 1 hour ago, thethinkertank said: Why is it therefore that entropy and energy play so wide a role in the speed of light, That is rather reverse. If you have body which is made of N number of particles, which has certain temperature T, and it's surrounded by vacuum, it's emitting photons in the all directions uniformly (therefor obeying inverse-square law) with speed of light. Energies of these photons depend on temperature of the body. It's called black body radiation. As a result of black body emission temperature of body is decreasing with time, and so does energy peak of emitted photons. The lower temperature, the smaller energy of emitted photons. If body is surrounded by other body, liquid or gas, temperature will decrease till finding equilibrium of the both body and environment. Additionally there will be other kinds of energy transfer like e.g. thermal conduction, convection. Basically atoms and molecules of liquid or gas are hitting our hotter body, and takes part of its internal energy with them. This is done by e.g. acceleration of their velocities. Air molecule with smaller velocity (smaller average temperature) after hitting hotter body is absorbing energy from body and air molecule is accelerated, then it hits other air molecule and it's repeated over and over again, millions or billions of times. There are also emitted photons correlated to temperature of air. Therefor somebody with IR camera can see it from distance. Search net for IR camera videos.

Is it then a viable supposition that growth of the human body also obeys the law of black body radiation? Would that explain why we grow older? I favour that view over the prevalent stem cell thesis. After all there is nothing different from say, a human being and a tree or even a sand dune, on the most macroscopic level. Energy is energy universally. And if all energy obeys the black body radiation effect that you stipulate, then surely we have right there the answer to growth and decay. -1 Link to comment Share on other sites More sharing options...

No... Things that aren't growing and things that are dead also obey the blackbody law. It only matters that it have a temperature. Link to comment Share on other sites More sharing options...

You're right, the biological processes depend on many other factors. Link to comment Share on other sites More sharing options...
MigL Posted June 18, 2019 Share Posted June 18, 2019 Seems someone learned a few scientific terms, and thinks that by stringing them together in a post, he's doing science. It is gibberish. Learn some science ! 2 Link to comment Share on other sites More sharing options...
