What would you think would happen if time ran backwards?

Question

Lets assume that all laws of physics and chem work equally good in reverse too.. do you think it would be possible or do you see any bottlenecks?

Answer 1

The dynamical equations of physics already do indeed work equally well in reverse. That is not the cause of thermodynamic time (that which causes us to age). You see, there are two things needed to explain any physical phenomenon (including the universe itself). The equations which describe how things evolve in space and time, and the boundary conditions of the problem itself (including initial conditions). The fact that the universe's initial conditions had low entropy (perhaps zero) resulted in thermodynamic time as we know it. The only way one could reverse this is if the end state of the universe were assumed to have low entropy instead. If that were the case, however, we would all be aging backward and our thoughts would be reversed. Silly us would then naively define the "beginning" of the universe to be at its end, and no one would notice the difference.

Answer 2

actually there are particles which are technically believed to be running backwards in time,e.g a positron can be defined as an electron running backwards in time,tachyons which are imaginary but plausible( I mean no current laws of physics are violated),are also considered as particles running backwards in time,Please note mathematically speaking time forward has +ve sign,and time running backwards has a -ve sign.Time's also expected to run backwards, if and when the Universe,starts collapsing back into a singularity,in what's known in physics parlance as THE BIG CRUNCH,the opposite of BIG BANG,that's possible only if the critical density of known matter's sufficient for a collapse,or we come up with a better theoretical understanding of our cosmology.

Answer 3

It is simply not possible. As all the activities which have happened till date can not be negated. By time running backward old people will get young man ,but what will happen to kids , it means they may have negative years of age.how the crops will grow, seed will be sown .Just everything will become impossible.

Answer 4

It can never happen. Its just a hypothetical concept that the time runs backward. Time is the only means by which we are able to seperate ''past'', ''present'' and ''future''.
Well, I must say that your question was indeed very thought releaving and interesting too.
God Bless

Answer 5

Time can't run backwards because time is not a *natural* feature of the universe. Time is nothing more than a concept we use to separate events into "past," "present," and "future."

Answer 6

I know one thing, I'll be the first one to jump in that time machine. Because I honestly feel that the day our era was doomed was when they constructed the first computer. I hate Technology. I mean wouldn't it be just fantastice if you will be able to see Greek warriers, British poets, Italian painters..

Answer 7

People will be born old, and die young!!
As the Universe which we know today runs, it is not possible.

Answer 8

Poop would go up your butt, anti-metabolize into food then come flying out your mouth.

I don't think so.
