What happens at absolute rest?

Question

I understand the twins paradox, that if you take two twins, put one in a very very fast space ship and leave the other on Earth, the one on Earth ages faster relative to the one on the ship. So, after traveling near the speed of light for a couple of years, when the one twin comes back to Earth he'll actually "be" younger than his twin. Well my question is what happens at absolute rest, if instead of traveling near the speed of light we travel near the speed of zero? Or is this absolute zero, like the absolute zero for temperature, impossible to achieve? Is it impossible to judge were absolute zero is in velocity; no reference point in the universe to judge zero from? But if we could make a spaceship that could compensate for all velocities, i.e., orbiting the Earth, Sun, center of the Milky Way, traveling through Milky Way, etc., would it "age" infinitely fast? So just a split second of absolute rest would be an eternity?

Answer 1

Travelling at speed 0 would have no different effect from travelling at any other speed. The only reason it would appear different, is that we on the Earth would are travelling very fast in comparison to speed 0. Basically, the only thing that effects the time is a difference in speeds between two objects. Two objects travelling at zero speed would not notice a change, just like two objects travelling at light speed would see no change.

Answer 2

There is no such thing as absolute rest. Any inertial (not accelerating) observer can claim with equal validity that they're at rest.

The "paradox" of the twins paradox is this: the person on the Earth thinks that they're at rest, but they see the person in the spaceship age slowly because, relative to them, the spaceship is moving quite fast. BUT, the person in the spaceship thinks that *they* are at rest, and thinks that the person on the Earth is moving away quite fast, and so is aging slowly. So, on the face of it, *each* person expects the other person to have aged less than themselves! But they can't both be right, and hence the "paradox".

I put the word paradox in quotations because actually there is a flaw in the reasoning which is somewhat subtle here. The existence of a paradox depends upon the fact that what each person sees is basically identical, except with roles reversed. And if what each person saw and experienced was identical, then indeed there would be a paradox. But there is a slight difference between the two people. The person on Earth just sits there, and thus is always in an inertial frame, and always in the same inertial frame (more or less). But the person on the spaceship had to turn around at some point, which means that they had to accelerate! But observers are only equal if they're both not accelerating. So the moment the spaceship starts accelerating, the symmetry/identical-ness between what the two people see and feel is broken, and the person on Earth is the only one who can claim to have valid observations under special relativity. So what the Earth observer sees, goes.

There are a couple of final points worth making about the Twins' Paradox. First is that it'd be nice to know what the spaceship person sees. After all, as long as they're travelling at a constant speed, they can claim that they're at rest and that the person on the Earth is moving and aging more slowly. It turns out that while special relativity won't help you a lot, *general* relativity can. It turns out that people who are accelerating see the rest of the universe (the parts that aren't accelerating with them) age faster. So, while the spaceship person sees the Earth person as having aged less than them up to the moment of the turning around, during the actual process of turning around, the spaceship person would see the Earth person age very, very rapidly. Of course, on the return trip the spaceship person would see the Earth person age slower than themself, but at this point the Earth person has aged a lot more, and so when the spaceship person returns, the two people are able to agree on who has aged by how much. The second thing to note is that if the spaceship person never turned around, then they would still be disagreeing as to who was aging slower. But they'd have to do this from a distance, and they'd both just think the other was crazy.

Answer 3

The absolute rest frame assumes that there are no other universes revolving relative to this one. However we have no other data physical data that relates to the outside of the Universe.
Hence, we have to assume that the galaxies are revolving and expanding their radii relative to a dynamic center of mass.
So the point of absolute rest would be continually moving in a 3 dimensional motion. This would be the point of the Universe where the sum of all the power of space at this junction is equal to zero. A similar form of Kirchoff law of space when all the current in the circuit of space adds to zero at a junction.
We are only able to postulate measurements from the same reference moving point. Since the point continually changes it is impossible to make an instantaneous measurement. This is what Heisenburgs principle was based upon.
In general all measurement must be made from a starting point. This starting point must be set to zero and the measurments are relative to that point.
So the absolute rest is taken as a zero point measurement.

The speed of light particle all have initial sources which dissipates the light particle mass radiation. We measure from the source a velocity = source velocity minus a velocity of light relative to the source.
However the source is moving relative to the same frame of reference that light velocity is then measured. So The velocity of light is now relative to a different frame of reference than when it left the source.
So the Newtonian -Galilean relativity was the correct relativity concerning moving sources of light as the absolute rest frame.
In response to your question about the Relativity twin paradox , I have the following deduction ;
The twin moving far away into space at luminous velocity appears from an observer on earth that that twin moved a large distance in practically no time at all,very close to zero time. while the twin sees the observer on earth to move very slowly.
But if the twin returns, the time reversed and the twins now appear at the same age.
What does that mean? =Its time conservation,where time Lost in one frame of reference appears as time gained in another frame of reference.
So the sum of all times in the Universe is a constant.
Time is conserved= that would be the conservation of time rule.A rule which was neglected beyond Einstein.

Answer 4

Absolute rest is fictive, impossible by the laws of physics and by what we can achieve. Even when we stand still we still move along with the Earth in relation to the Sun, to the other planets, to the Galaxy center, and to other galaxies.
Einstein said that if speed of light is constant, than time is elastic, but the results from an apsolute rest wouldn't differ from the ones of the relative rest. It's a quite small difference in speed.

Answer 5

There is no such thing as "absolute rest." That's the entire point of relativity. Every inertial observer is entitled to consider himself at rest and do physics in his reference frame. There is no preferred reference frame; no absolute rest, only rest compared with other things.

In other words, there is no experiment that can be performed in a windowless room that will yield your velocity. In order to calculate a velocity, you have to look out the window and calculate your velocity *relative* to some exterior object.

In the twin paradox, we mean that the spaceship travels at nearly the speed of light relative to the Earth.

Answer 6

an substantial question could be, for a fashion long ought to absolute 0 be maintained? and how ordinary replaced into it to get to absolute 0? the answer to those questions could have substantial useful ramifications. A equipment at absolute 0 is entropy unfastened. It nevertheless has a nil-element capability, yet atoms could be in appropriate order and coherence. i do no longer think of it being too diverse from a Bose-Einstein condensation. As for whether breaking the third regulation of thermodynamics breaks different regulations of physics, i do no longer think of so. The 2d and third regulation of thermodynamics are statistical regulations. they're actual using fact the statistical threat of violating them is so small that they are going to exceptionally lots in no way take place in the process the entire life of our universe.

Answer 7

The universe is constantly expading, so everything is moving with respect to where the Big Bang started. If this hypothetical spaceship were moving opposite to the expansion, it would be moving away from Earth/Sun/Milky Way/pick your reference point. So I guess that means there's no such thing as absolute rest.

Answer 8

There is no absolute rest, the Michelson Morley proved that and led Einstein to determine that time dilated. The rest of the question is mute. I am unaware of any theory referring to time conservation, time is fixed in space, it is always, NOW.

Answer 9

There is no absolute zero velocity or absolute velocities at all; all velocities are in reference to something else.
