Anonymous users2024-02-11You may not have remembered, but it should be the relative time formula of the Lorentz transform: t=t0 (1-v2 c 2). In high-speed motion, the "clock slows" effect occurs close to the speed of light, and time dilates so that the passage slows down, and this formula calculates the relative time of a high-speed traveler.
In addition, approaching the speed of light also produces a "shrinkage" effect, and the length will be shortened, and the relative length formula of the Lorentz transform is l=l0 (1-v2 c 2).
t is the motion frame time, t0 is the stationary frame of reference time, l is the motion frame scale, l0 is the stationary frame of reference scale, v is the velocity, and c is the speed of light.
Sub-light time will only slow down and not stop, while if it moves at the speed of light, it will stop, which can also be calculated using the relative time formula, which is the "bell stop" effect. Moving at the speed of light also produces a "ruler elimination" effect, which can also be calculated using the relative length formula. The "bell inversion" and "ruler inflation" effects of faster-than-light motion are based on the first two cases, and those two formulas cannot be used here, because the v in those two formulas must be less than c.

Anonymous users2024-02-10Root number Do it yourself, hehe. v2
In the above factor of c2, v is the speed of the object's motion and c is the speed of light. The v2 above is v squared and c2 is c squared.
For example, if an object moves at a velocity of v, then its temporal effect is the normal time multiplied by the above factor.
As can be seen from the above, when the speed of the object reaches the speed of light, this factor is equal to 0, time stands still, and the speed of light is the limit of speed, and it can only be approached infinitely if it is not reached.
The length of the object is the length of the object at rest multiplied by the factor above.
The mass of the object is the mass of the object at rest divided by the above factor.

Anonymous users2024-02-09According to the theory of the universe, time advances when the universe expands, the end point of the universe expansion, time stops, and when the universe begins to contract, time regresses. Of course, there is also a correlation between time and speed in this process. When the faster-than-light universe expands, time goes backwards, and other analogies are OK.

Anonymous users2024-02-08e=mc The speed of the object is close to the speed of light, and time slows down.
The velocity of the object is equal to the speed of light and time will come to a standstill.
If the speed of the object is greater than the speed of light, time will go backwards.
Theoretically, it is.
But no matter can reach the speed of light, because to have a very high velocity, you have to have a very small mass.
As small as the mass of a photon can speed up to the speed of light.

Anonymous users2024-02-06Whenever I'm at home on vacation, I feel like time flies, and there are many moments when I don't want to go to work, and I really wish that time could stop.
Nowadays, many young people feel that the reason why time flies fast is that life is too stressful, and they are busy all day long, so that Zheng Nian gradually forgets time, which you can understand as making full use of time and making yourself more fulfilling. A fulfilling life will indeed bring you a lot of fulfillment and will not let time slip away.
In fact, the biggest cost of a person is time, and most people consume precious life time in ignorance, if you feel that you are doing something, this thing is intentional to you, can bring value to you crying out for great hardship, can make you happy and satisfied.
The real waste of time, except waiting, is to have nothing to do, nothing to do. Waiting is the biggest waste, is disrespectful to the time of your life, there was no mobile phone before, so just wait, now there is a mobile phone, then brush ** to play games, feel that time flies fast, think about why this is happening? If you don't do a good job, adjust your time reasonably, and don't procrastinate.
Do you find that when you are waiting to do something, the more you get to the back, the more anxious you are, the more anxious the time is, sometimes it is so slow that time is in your heart, ticking like a sleepy sound, if you put your mind steady, you will not have this feeling.
In our nature, the maximum speed at which an object moves is still the speed of light so far, as we all know. While quantum entanglement is theoretically faster than the speed of light, it is only a theory after all. Being the fastest velocity in the universe, it is impossible for all mass objects to reach the speed of light because the mass of the object increases with velocity. >>>More
Time stops when the speed of light is reached, which is a corollary of the special theory of relativity, and the formula for time dilation in the special theory of relativity is shown in the figure. When v=c, people of the k0 system will consider the arbitrary time interval of the k system to be infinite, i.e., time has stopped.
The first floor YY party generally believes that the universe is constantly expanding under the action of dark matter, and the force of dark matter is manifested as repulsion - that is, anti-gravity and repulsion is greater than gravity, so in the big ** universe model, the universe is constantly expanding. But those Spanish scientists don't think so, they think that dark matter is not anti-gravity, but in strengthening the effect of gravity - that is, the force of dark matter acts in the same direction as gravity, so that the whole universe shrinks under the action of gravity and dark matter, according to the theory of relativity we can see two causes of time slowing down - speed, gravitational field, with the original big ** theory, time is accelerating, the reason should also be the relativistic effect, and in the new (correct or not is unknown, Personally, I think it's wrong) theory that time is slowing down, and of course this theory cannot explain the redshift phenomenon. As for the student who thinks that only black holes can make time stand still, I think she didn't take into account the relativistic effect of speed.
Time does not give you the opportunity to regret it, it means that what happened in the past cannot be changed, only regret. But this is a memory that time has left for you. Whether the good or bad makes you regret the past or not, one day you will find that they are the most precious memories when looking back. >>>More
I think it's a Pisces, she has a gentle and kind personality, she is willing to give for others, and she doesn't complain. Aries, Sagittarius. The personalities are all relatively cheerful.
