    For example, if the static mass of a photon is 0, its velocity can reach the speed of light. If the mass effect formula is still applicable, then we can substitute m0=0 into it to know that no matter what speed space moves at (even if it is equal to or greater than the speed of light), its mass m is always 0, and theoretically it can maintain its speed without energy, so it can easily exceed the speed of light.

    These two statements are not contradictory, the speed of light is inherently very happy, and the speed of expansion of the universe cannot exceed the speed of light, and these statements have their own truths.

    The speed at which the universe expands and the speed at which it travels within the universe (the speed of light) are two completely different concepts. The speed at which the universe expands depends on the contrast between the density of energy inside and outside the universe, i.e., the pressure, similar to the expansion of a balloon. The speed of propagation within the universe, the speed of light, depends on the static mass of photons and the quantum density of the space inside the universe.

    Albert Einstein proposed the "principle of the invariance of the speed of light", but even if the facts around us are negative, no one refutes this, on the contrary, it is necessary to assume that the speed of light is a constant quantity.

    The speed of light is considered to be a constant of 300,000 kilometers per second.

    So, is this constant quantity in line with the facts?

    In the space of the solar system, sunlight refers to the light emitted by the sun. This speed of light may have reached Einstein's constant speed of light, or exceeded Einstein's constant speed of light a little, otherwise, no one would have admired Einstein's theory of relativity.

    However, our daily life tells us that the speed of light simply cannot reach Einstein's constant speed of light. Otherwise, Einstein's theory of relativity would be seamlessly integrated with Newton's classical theory.

    The light we encounter in our daily lives is like this:

    A low-power light can be kept on for an hour, and although it can make people within its range see the light at the same time, it cannot make people outside the range unable to see the light.

    A high-powered light can be kept on for an hour, and although it can make people within its range see the light at the same time, it cannot make people outside the range unable to see the light.

    However, low-power lights and high-power lights are the same, and this is the range that shines almost simultaneously;The difference between low-power lights and high-power lights is the range of light.

    Therefore, we can imagine that the amount of energy released by the light source is directly proportional to the range and speed of light of the light source. However, it is impossible for a light source such as a light source to shoot the speed of light emitted by the sun, which is only a few tens of kilometers at most, because its range is only a little bit.

    In the same way, we can speculate that if a light source emits more energy than the sun, then it must emit a faster light than the sun. Because the speed of light is directly proportional to the energy emitted by the light source.

    Because this is the expansion of the universe itself, and the speed of light is only the upper limit of the speed of all matter in the universe. To put it bluntly, it means that the speed of expansion of the universe will not be constrained by the law that "the speed of light is insurmountable". We all know that the vastness of the universe, its many mysteries, and countless unknowns have been one of the themes that many human scientists have been tirelessly exploring so far.

    The emergence of the famous physicist Albert Einstein in the last century brought us three important theories of physics: special relativity, general relativity, and quantum mechanics. In particular, the two systems of relativity have led our scientific development for decades, and their importance is self-evident.

    The biggest cornerstone of the theory of relativity is the so-called principle that "the speed of light is insurmountable". To put it bluntly, the speed of light is the upper limit of the speed of any object in the universe, and only microparticles that do not have mass and have infinite kinetic energy when traveling in a vacuum can reach the speed of light;

    It is impossible for any other object to cross the threshold of 300,000 kilometers per second. This has become a universal golden rule; However, the big ** theory of general relativity reveals the fact of "the expansion of the universe";

    From the primordial gravitational wave signals we detected at the end of the last century, we discovered another astonishing fact: the universe is expanding faster than the speed of light. Moreover, the data shows that it is at least three or four times faster. What does this mean? Is the theory of relativity being subverted?

    Of course not. "Cosmic expansion" is the continuous expansion of the space-time of the universe itself; It's not just speed. To put it bluntly, it doesn't follow any of the existing laws of physics at all.

    Therefore, it is understandable that the universe is expanding faster than the speed of light. It is worth mentioning that it was precisely because of the inspiration that the universe expands faster than the speed of light that NASA proposed the idea of the so-called "curvature engine" migration technology in 2012;

    It is said that this technology can make the spacecraft faster than the speed of light by folding space.

    Because the speed at which the universe expands is relative, and the speed of light is absolute, the universe will expand faster than the speed of light.

    Strictly speaking, the speed at which the universe expands is not the speed in the true sense of the word. As the universe expands, light also spreads, and the speed of light plus an expansion speed will make the universe expand faster than light.

    Because the speed of light is limited to objects in the solar system, and from the perspective of the universe, it may be surpassable, and I think there are many mysteries in the universe.

    The expansion of the universe is discussed in terms of the rate of expansion, which is a concept of expansion that denotes the size of space at a certain place per unit of time, and should generally be labeled as a percentage without dimension. For example, the expansion rate of space is 50% seconds, etc., not the velocity dimension, so the so-called "universe is expanding at the speed of light" description (described as a whole) is wrong (logical error) and does not exist.

    So, what is the so-called star that is 10,000 light-years away from us is leaving us 'faster than light'? This is because the "distance growth" between a particle and the observer at a distance of sufficient distance will be faster than that of an observer standing in a uniformly expanded space, so that the "distance growth" between a point at a sufficient distance and the observer will exceed the "speed of light", but more than the speed of motion of matter and energy itself that is not at this point of matter;

    For example, take a 100m long ruler and the observer stands at 0 o'clock on the scale of the ruler and observes the points on the scale 1m, 10m, 100m. If we assume that the ruler expands uniformly at an expansion rate of 50% sec. After one second, the distance between the points on 1m, 10m, and 100m and the observer at point 0 becomes, 15m, 150m, and the speed at which these points leave the observer is:

    5m/s,50m/s。If it is a ruler of 2 million meters, then the speed at which a particle on a scale of 1 million meters leaves the observer on a scale of 0 is 500,000 m s, which exceeds the speed of light. But this is only an elongation of the relative distance caused by the expansion of space, and the particle itself does not move.

    Therefore, the concept of "cosmic expansion rate" is itself wrong, and it is correct to use the term space expansion rate.

    Another corollary is that we can't actually observe the star that is moving away from us at more than the speed of light due to the expansion of space.

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.

The theory of relativity does not allow matter with mass to move faster than the speed of light, and if the speed of light is reached, the mass will be added to infinity, so the theory of relativity does not allow matter carrying mass and information to exceed the speed of light. In fact, faster-than-light is not impossible, as long as it does not carry mass and information, faster-than-light is allowed. The expansion of the universe, the wave function of quantum mechanics, and the tachyon do not violate the special theory of relativity.
