Anonymous users2024-02-06Space has field properties, and photons propagate in the field in the form of waves. Of course, using waves to accelerate photons can only increase the energy of photons, but not the speed of photons, which is determined by the basic properties of waves.
In addition, the exact way in which the interaction between the field and matter is realized is not yet conclusive. Consciousness is subjective cognition, and the field cannot act on it. Consciousness has only height and depth, not speed.
In addition, velocity itself is a variable that describes the spatial distance of two objects to the time difference, and cannot be a necessary condition for one system to cause space-time distortion to another. The formation of the inevitable conditions of space-time distortion should be related to the basic properties of matter, such as mass, temperature, etc. Speed cannot exist as a more fundamental quantity.
If space-time is distorted by speed, then there are countless substances in the universe that reach or close to the speed of light, but the space we live in is still the same.

Anonymous users2024-02-05I think so, but of course it's not easy to verify. Time is a reaction of movement in consciousness, so to speak, there is no time in the first place. We don't know what an object looks like when it reaches the speed of light, which means that the object that reaches the speed of light may no longer be an object but a wave.
At the speed of light, there are only electromagnetic waves.

Anonymous users2024-02-03That's right, I think it's the same, when the speed of light reaches a limit, time stops, and human neurotransmission stops.

Anonymous users2024-02-02The faster you move, the slower your time will pass relative to someone who moves slower. The speed of light is the fastest in the universe.
At this point you will be slower than everyone else, much, very slowly, but time will not stop. So some people say that reaching the speed of light will travel through time and space, to the future. But there are also some people who say that reaching the speed of light will enter a parallel universe, but I don't know if it's true or not.
No one has ever reached the speed of light, so everything is just theoretical.

Anonymous users2024-02-01Reach the speed of light and time stops! The speed of light is recognized as the fastest speed in physics, and it is the most extreme speed in the universe. The speed of light is 299,792,458 meters and seconds (Note:
Beyond this speed, the second will be negative), and one and a half times around the earth in one second! That is, I am at the South Pole and you are at the North Pole, and I run at the speed of light at 14:00 to punch you and run back to the South Pole or 14:
00 points! Doesn't that make sense that time has stopped? Suppose that I ran from the South Pole to the North Pole faster than the speed of light, and I could see for myself that I was still standing at the beginning of the South Pole after returning to the South Pole.
In fact, these are just hypotheticals, and matter cannot move at the speed of light, because the mass is infinite when the speed of light is reached).
Of course, all this is Einstein's theory of relativity, it can be said that Einstein is a madman, without him there would be no theory of relativity, and the so-called time stop and time reversal are not time pauses like **TV or go back to the past beyond time and space, but are linked to speed.

Anonymous users2024-01-31The first half of the upstairs is just a paradox of Einstein's thinking, and Einstein made a bold assumption by thinking about the paradox: the speed of light does not change (note: this assumption is very important).
How do we understand the assumption that the speed of light does not change? -- The speed of light is constant relative to his speed (300000000 m s) regardless of the state the observer is in.
As mentioned upstairs in this paradox, when you are moving at the speed of light (300000000 m s), the light you see is still 300000000 m s relative to your velocity, not walking with the light.
Here's another example to help you understand that the speed of light does not change
A takes a flashlight and stands still, B moves at a speed of 100000000m s, when B just passes A, A turns on the flashlight in the same direction as B's movement, so in A and B's opinion, what is the speed of the flashlight beam relative to itself?
In the usual mind, the velocity of the beam seen by A is 300000000m s relative to himself, and the velocity of the beam seen by B is 200000000m s relative to himself.
In fact, because the speed of light does not change, the beam velocity seen by A and B is 300000000m s relative to themselves.
Don't doubt the assumption that the speed of light does not change, it has now been tested by countless experiments. And Einstein'Special theory of relativity'It is on this basis that the relativity of time and space is derived--- which are different with respect to different observers.
Since you are talking about time, let's analyze the relativity of time based on the example above. The time elapsed when the beam moves to 3000000000m from the armor.
In A's view, the velocity of the beam relative to A is 300000000m s, so time = 300000000 300000000 = 1 second.
Taking B as an observer, because 'the speed of light does not change', the velocity of the beam relative to B is 300000000m s in B's opinion. Then the velocity of the beam relative to A is 3000000000 + 1000000000 = 400000000m s, so when the beam moves to 300000000m away from A, the time is 3000000000 400000000 = 3 4 seconds.
It can be seen that B's time is shortened by 1 4 seconds, that is, when B is moving at a speed of 100000000m s, the time slows down.
If you continue to derive that the faster B moves, time will be slower, and when the speed of light is reached, time stops, and when the speed of light is exceeded, time is negative, i.e., time reverses.
Why don't we feel the relativity of time? Because usually our relative velocity is very small, the relative time difference is very, very small.

Anonymous users2024-01-30The speed of light is independent of time, and the speed of light in a given medium is constant.

Anonymous users2024-01-29Time is like a piece of moving at the speed of light, you can only look at it one by one, when your speed is equal to the speed of light, what you see is always a **, when you exceed the speed of light, you can see the previous **, but you will not travel through time, or in other words, light and time, are already in two different time and space, maybe parallel universes really exist, all this has to wait for scientists to slowly discover.

Anonymous users2024-01-28When a person moves at the speed of light, does time stand still?
Understood from a relativistic point of view, this seems to be no problem! But after careful consideration, in fact, this conclusion is very problematic, because it is possible to understand the relationship between time and the observer in the special theory of relativity one-sidedly, so let's briefly discuss whether time is still when a person's speed reaches the speed of light?
Does time really stop at the speed of light?
How can you prove that time is stagnant in a lightspeed ship? In fact, a trigonometric function can prove it! But what we're talking about today isn't about this outcome, but about who looks like time has stopped? Everyone knows the formula of the clock-slow effect, and it is not difficult to understand!
When u=c, t= time is stagnant, but the problem also comes, the formula is dead, but man is alive, this formula for calculating time is for the observer, and the above formula is true when we intervene as an observer! If there was a telescope that could see this person leaving at the speed of light, would it be possible? It's really possible, but when you see the picture of the moment when you always leave, it's stagnant, like **!
But you can't see anything, because we ignore the red shift of the spectrum, according to the calculation, as long as it reaches more than 100,000 kilometers, the ultraviolet spectrum will be shifted to the infrared spectrum, and all the original visible light will not be visible, and most of the world around us is very little in the ultraviolet or above spectrum, unless it is an ultra-high temperature object!
And what about the people in the spaceship? Did their time really stop? Actually, it's not, because the ground observer has no effect on them, saying that serious birth, old age, sickness and death, simple eating, drinking, and Lazar are indispensable, but the problem is that all the actions on the light-speed spacecraft will extend to infinity in the observation view, and maybe they haven't completed this action until the end of the universe!
So whose time stands still?
In fact, no one's time stands still, the clock on the spaceship still passes minute by minute, and the crew will gradually get old, and the accidentally cut hand will still be bleeding, and there will be no difference from the ground! And not to mention the observer on the ground, all of us are observers, so do we stand still in time? Apparently not!
So time is only relative, why is it called relativity? Maybe that's one of the reasons ha! So everything does not require absolutes, there is no absolute thing in the world, but maybe the speed of light is really an exception, this thing does not change with the frame of reference, of course, the fact that the speed of light does not change has been proven more than 100 years ago, if you are interested, you can learn about the Michelson-Morey experiment for the proof of the constant speed of light!

Anonymous users2024-01-27Time and speed are two different concepts, but when it comes to the speed of light, terms like light years are often confusing. The speed of light refers to the speed at which light waves or electromagnetic waves travel in a vacuum or medium. c=299792458m/s。
A light-year is a unit of length that measures the distance that light travels in a straight line for a year's time in a cosmic vacuum.
Then there is a certain understanding of the time involved. For example, if a star in the Milky Way is 10,000 light-years away from Earth, the light emitted by that star would need to travel at the speed of light (assumed to travel in a vacuum) for 10,000 years to reach Earth and be observed. In other words, the star observed on Earth is what it was 10,000 years ago.

Anonymous users2024-01-26How to say it, I am not a highly educated person, but I can only use my own opinion to say, I understand the relationship between time and light, what human beings receive or see is transmitted by light, I set two points A and B a light year away, light years are not strange to everyone is the distance of light running a year, A sees B is B a year ago, on the contrary, B sees A is also A a year ago, if I make a spaceship that can run a light year in one second, it only takes one second to reach B a year ago plus one second, At this time, looking at A from B to A two years ago, plus one second, this can be regarded as going back to the past, then again, if my spaceship is exactly the speed of light, it will take me a year to get from A to B, and then it will take me a total of two years to come back from B, but when I come back, I find that A's time and my departure time have not changed, but the two years I experienced are even if time stands still, isn't it? But what would happen if I had to travel to the future, and that's what I'm most confused about, and I hope you can discuss it together.
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
Haven't you heard of virtual matter?
When scientists do quantum experiments, they find that there is a faster-than-light induction phenomenon between two related particles, since there is induction, there must be matter that transmits information between two particles at a speed faster than light, so scientists assert that if the theory of relativity is correct, then there must be a substance with a negative mass (or virtual mass), and the speed of motion of this matter cannot be lower than the speed of light. >>>More
Since the expansion of the universe is mentioned, another idea must be involved, whether the universe is finite. If the universe is finite, it can't be far enough. In fact, at a distance of enough distance, the mathematical model of the universe is used to simulate it has always been an undecided question. >>>More
Time and space are all produced by motion, which means that time and space have a physical meaning when all objects have relative motion. Otherwise, when all objects have no relative motion, there will be no physical significance, only mathematical significance. >>>More
