Because it is shrinking, so is its entropy. To preserve the GSL, the entropy of some other matter system must increase. The trouble is that
the total decrease in entropy is actually infinite, and nothing could compensate for that
. Therefore the time machine would violate the GSL.
Does time travel violate the First law of thermodynamics?
The laws of thermodynamics prove that entropy must increase as time moves forward. As shown by Villie and others,
travelling backwards through time might not breach energy conservation
, but since you would be able to do something when you got there, you would have reduced the entropy there.
What is the second law of thermodynamics and why does life not violate it?
The law centres around the idea that when energy is transferred from one form to another, entropy is increased as a result.
Living organisms are not a closed system, and therefore the energy input and output of an organism is not relevant to the second law of thermodynamics.
Does time travel violate the laws of physics?
Yet
time travel does not necessarily violate the laws of physics
. In Einstein’s theory of gravity — general relativity — space and time are merged as spacetime, which allows for the possibility of pathways that could bend back to the past and loop back to the future. Such paths are known as closed timelike curves.
Does time travel contradict the second law of thermodynamics?
The Second Law says that this number always increases as time passes
. Even black holes obey a version of the Second Law. Their entropy turns out to be proportional to the area of their event horizon. In other words, the area of a black hole, plus the entropy of any matter outside of it, always increases with time.
Does life go against entropy?
In this direction, although life’s dynamics may be argued to go against the tendency of the second law,
life does not in any way conflict with or invalidate this law
, because the principle that entropy can only increase or remain constant applies only to a closed system which is adiabatically isolated, meaning no heat …
What does time travel violate?
Time travel paradoxes arise from the fact that departure occurs after arrival according to one observer, and before arrival according to another. In the terminology of special relativity, time travel implies that the timelike ordering of events is not invariant. This violates our
intuitive notions of causality
.
Do wormholes violate Thermodynamics?
No, black holes do not violate the 2nd Law of Thermodynamics
.
Can entropy affect time?
Entropy does not change with time
, and entropy does not have a tendency to increase. It is very common to say that entropy increases towards its maximum at equilibrium.
Does the second law of thermodynamics apply to biological life?
The second law of thermodynamics is a quantitative statement, not a hand-waving one about disorder. It tells us that the entropy of an isolated system always increases. But
biological systems are not isolated: they exist in an open environment
.
Is time travel possible in quantum physics?
Until recently, most studies on time travel are based upon classical general relativity.
Coming up with a quantum version of time travel requires physicists to figure out the time evolution equations for density states in the presence of closed timelike curves (CTC)
.
Is time Travelling possible?
In Summary:
Yes, time travel is indeed a real thing
. But it’s not quite what you’ve probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second.
Is it possible to bend time?
Science does support some amount of time-bending
, though. For example, physicist Albert Einstein’s theory of special relativity proposes that time is an illusion that moves relative to an observer. An observer traveling near the speed of light will experience time, with all its aftereffects (boredom, aging, etc.)
Is reverse entropy possible?
It is not possible to reverse entropy in a closed system
. Therefore, as changes between events progress, all closed systems over time will tend toward high entropy. Obviously, entropy will decrease because of statistical probability in the very short term, but it is extremely rare.
Is the universe a closed system?
The universe itself is a closed system
, so the total amount of energy in existence has always been the same. The forms that energy takes, however, are constantly changing.
Is death a state of entropy?
Real processes tend to go in the direction of increasing entropy. Aging can be envisioned as an irreversible process of entropy accumulation. Getting older means having less control of body functions, being more disordered. Death is the ulti- mate disorder,
a state of maximum entropy
.
Are humans high or low entropy?
Global disorder still increases, but for that organism, the ability to locally reduce entropy is literally a matter of life and death. An obvious example of this principle is humans.
Our human bodies are very highly ordered compared to inanimate things like air and water.
Can you destroy entropy?
Entropy is generated everywhere and always, at any scale without exception, and
cannot be destroyed by any means at any scale
. “Entropy of an isolated, closed system (or universe) is always increasing” is a necessary but not sufficient condition of the Second Law of thermodynamics.
Does time travel break conservation of mass?
That means that according to conservation of mass, a quantity equal to your mass has been subtracted from something else. But
mass doesn’t spontaneously disappear in order for time travel to occur, so that’s impossible
.
Could time loops exist?
Einstein’s general theory of relativity allows for the possibility of warping time to such a high degree that it actually folds upon itself, resulting in a time loop.
Can energy go back in time?
On a cylinder as on a circle, energy can flow without being created or destroyed. Energy conservation need not be violated. Moreover,
energy always flows from the past to the future
. It’s just that after flowing into the future for some amount of time, it finds itself back in the past, and so does everything else.
Do black holes violate entropy?
The second law of thermodynamics requires that black holes have entropy
. If black holes carried no entropy, it would be possible to violate the second law by throwing mass into the black hole.
Does Whitehole exist?
White holes cannot exist
, since they violate the second law of thermodynamics. General Relativity is time symmetric. It does not know about the second law of thermodynamics, and it does not know about which way cause and effect go.
Why can’t white holes exist?
Why white holes may not exist
Even if large white holes did form,
they probably wouldn’t hang around too long
. Any outgoing matter would collide with the matter in orbit, and the system would collapse into a black hole.
