Two relativistic contradiction

Keywords: theory of relativity, time, space, motion, light, reference system

The first theory of relativity we learn the theory of relativity, is this: Assuming constant speed of light, that according to the principle of constancy of the speed of light, the introduction of the relativity of simultaneity; relativity of simultaneity usually cite the example of this' assuming a long train in quickly along a straight track uniform traffic. compartment has a light source in the center issued a flash, flash, shine on the anterior and posterior wall of the compartment, which is two events. observer in the car that the two events are simultaneous. his opinion a good explanation, because the compartment is inertial system, light forward, after the spread of the same speed, the light source in the center of the compartment, the flash of course, will arrive at the same time around the two walls (Figure A). observer under the car disagree. observed flash first to reach the back wall, after the arrival of the front wall of his explanation: the ground is also an inertial frame, flash forward, after the transmission speed on the ground is the same, but in flash fly two walls process, the carriage forward traveling some distance, the forward light propagation from the longer to reach the anterior wall of the moment will later (Figure B), these two events is not the same. '

This example has a feature that the direction of movement of the light with the same or opposite direction of movement of the reference system (train).

Then launch time relative. Time relative often cite this case 'envisaged in a train for uniform linear motion velocity v, aligned vertically above guest h the height of the side mirror hit a laser beam, for him, and all trains person (referred to as "static system"), this laser beam from the emitted to return to the light source position [See Figure (a)] as "ticks" once the time interval T0 = 2H / c. Now to ask how the observer would look at the measurement results on the ground? Judging from the ground, which is a movement of "light clock" some distance train travel forward in the process of light propagation, the people on the ground (known as "dynamic system") that the only optical clock ticks "once during the beam is along the path ABC transmission [See Figure (b)], it is adopted from greater than 2h, if speed of light is c, then, in their opinion, this movement optical clock" ticks "once time △ t longer. Further application of the Pythagorean theorem, the quantitative relationship can be obtained: noticed, so △ t> △ t0. The results show that: the movement of the clock slows down. '

This example has a feature that is the timepiece movement direction and the movement of the light direction vertical.

Draw space relative. The direction perpendicular to the direction of movement does not shrink. (Perhaps the vertical direction.)

Read here, you may or said no problem ah? ! Then look.

The second theory of relativity, or that the theory of relativity supplement. Assuming constant speed of light or that according to the principle of constancy of the speed of light, and then launched what? Relativity of simultaneity it? My example above, while the relative in the example, but the light is not forward after the spread, but spread up and down. Means that the direction of light perpendicular to the direction of movement of the reference system, like, like watch the direction of movement with the movement of the light perpendicular to the direction. We reach this conclusion: the process of the car and the car under the observer to come to light at the same time to reach the conclusion. Accordingly, when the perpendicular to the direction of the light and the direction of movement of the reference system does not exist while the relative. [1]

We know that in the sub-movement and co-movement sub-movement and co-movement is to arrive at the same time, how to understand the theory of relativity? This relationship still exist? Based on 'when the direction of the light and the direction of movement of the reference system is vertical, not exist simultaneously relative', the light is replaced by the other objects, we conclude when perpendicular to the direction of movement of the object with the direction of movement of the reference system does not exist, while relative sub-movement and closing movement is to arrive at the same time. Has nothing to do with the choice of the reference system. For example, free fall flat projectile motion, or that the free fall flat projectile motion and horizontal movement. For example, closed glass tube in red wax uniform upward movement of the glass tube to the right uniform motion, red wax can be seen as participate in two sports at the same time. Sub-movement and movement are arriving at the same time. Arrive at the same time on the stationary arrive at the same time, in uniform linear motion system.

According to the 'when the direction of the light and the direction of movement of the reference system is vertical, not exist simultaneously relative' just arrived at the same time, then in the example of the relative nature of the above time, watch the direction of movement with the movement of the light perpendicular to the direction, We would come to the light path to walk a straight line with a slash, but just to arrive at the same time. Contradict this conclusion with the constant speed of light.

If you change the light experimental relativity in the cited example, that the light direction of motion and the direction of motion of the reference system is the same or the opposite, then the movement of the clock is slower? Or faster? The movement of the clock is slower or faster associated with the 'light and the direction of motion of the reference system'? The slower one direction, another direction is faster?

To back double away slow in one direction, another direction becomes faster, the same speed of the reference system, the constant speed of light, then whether the slower and faster cancel each other out? Time change? [2]

You understand how the theory of relativity?

As for me, worse from motion [3] the perspective of the constancy of the speed of light. A movement of objects through space with its own sports-related, that is their own speed; space between two objects change motion difference. Constancy principle says is the speed of light, the light itself; light is changed with another object, the space between the light and another object motion difference, i.e. the relative speed of light and another object both the situation.

For space time.

Space of such a nature: (any object can do reference system) reference system with the space is still, regardless of the reference frame how movement, including variable speed, will not change the stationary state of the reference system with space. Or reference system with space to move together. [4] (see the previous article, "the essence of space)

Description of time and space

We know each other stationary reference frame with space, The space can be described,

, Any object can be described space, the other objects are in this space. Second, any object in the space of the other objects described.

Well, the time can be described: First, any object can be described time and other objects at this time. Second, any object at the time described by the other objects.
