Cannot fly at the speed of light. Let's not talk about whether new energy sources have been discovered. Even if it is discovered, there is no corresponding aviation technology to use it.
-
You can imagine it. Because antimatter is a new energy source that is many times more energetic than nuclear energy, it is conceivable that it can be used to travel at the speed of light.
-
Light-speed flight only exists in the imagination, and with the current level of human technology, even if a more powerful energy source is discovered, it will not be able to reach the goal of light-speed flight.
-
This new energy source can be faster than the speed of time, otherwise it will not be able to travel at the speed of light.

Mankind is a great civilization that has created one miracle after another. It took only millions of years for human beings to evolve from primitive life to intelligent life, and I have to say that this is a miracle of life, you must know that the dinosaurs, the overlord of the earth 65 million years ago, lived on the earth for hundreds of millions of years, and did not grow into intelligent life, while human beings only took millions of years.
Another miracle of mankind is that it took only hundreds of years from the beginning of the industrial revolution to develop science and technology to go out of the earth, this is a miracle of civilization, even if there are many civilizations in the universe that are countless times stronger than human beings, but it is believed that there are very few civilizations that can have such a rapid development rate of human civilization. Driven by science and technology, human beings have developed rapidly and gone out of the earth to explore the universe.
Human beings can get out of the earth, inseparable from the development of energy, with a strong energy, rockets can get rid of the shackles of the earth's gravity, fly out of the earth, human satellites, probes, spaceships, etc. can enter space. It can be said that energy is the key to human exploration of the universe, and without strong energy support, exploring the universe is a dream.
Although human beings have been able to get out of the earth, our technology is still very backward in front of the universe, and it will take nearly 7 months from the earth to Mars, and even the solar system cannot go out at such a speed, let alone explore the entire galaxy and the entire universe. The speed of our spacecraft seems to us to be quite fast, but in the face of cosmic distances measured in light years, it is no different from turtle speed.
In order for human beings to have the ability to explore the solar system initially, the speed of the spacecraft must reach at least sub-light or light. It is important to know that the diameter of the solar system may also be more than 2 light-years, and it will take 1 light-year to fly out of the solar system at the speed of light from the sun. The most important thing to make the spaceship fly at sub-light speed or light speed is energy, as long as there is more powerful energy, none of this is a dream.
The most powerful energy source of human beings is nuclear energy, but our use of nuclear energy is not very strong, controllable nuclear fusion is the real nuclear energy, what happens inside the star is nuclear fusion at all times, if human beings can collapse enough to master nuclear fusion technology, so as to develop a nuclear fusion engine, the speed of the spacecraft to reach sub-light speed is not a big problem, however, controllable nuclear fusion is still in its infancy, and it may take about 50 years to achieve it.
Although the energy source of nuclear fusion reaches the speed of sub-light at the speed of the spacecraft, to reach the speed of light, nuclear fusion is still not possible, and more powerful energy is needed to support it, and this energy scientist has found it, it is antimatter.

Human beings have come to the present step by step, experienced many difficulties, and stepped into the high-tech era from the previous backward era, which shows that human beings have worked hard in the process of development to get to the present. Since the industrial revolution of mankind, human beings in the field of science and technology, as if "riding a rocket", in only more than 200 years, the quality of human life has been greatly improved. On such a comfortable earth, people began to breed and reproduce the next generation, so that there are more and more human beings on the earth.
In recent years, in order to improve the progress in the field of science and technology, a large number of resources on the earth have been consumed, and some resources have been depleted, and these resources are non-renewable resources, which shows that human beings only consider themselves in the process of development. On this issue, human beings are gradually replacing it with new energy, such as tidal energy, wind energy, solar energy, etc., which can reduce the consumption of the earth's resources, but cause great pollution to the environment.
Human beings are not stagnant, but continue to develop by passing on from generation to generation, and the number of humans on the earth has been increasing, but the resources on the earth are decreasing year by year, so they have to find other energy sources to replace the depleted energy on the earth, so scientists want to use light sources. Light is extremely important to us humans, and it is with light that plants can photosynthesize. Is the light source really that easy to control?
The speed of light propagation is very fast, so far nothing can exceed the speed of light, which also means that the light source contains infinite power, cracks Some people believe that the way to take the light source can start from the particles of light, the speed of light travel is very fast, if human beings can successfully "capture" it, then human beings can use it to create a faster-than-light spaceship, so that it is easier for human beings to go to the universe.
Due to the limited technology of human beings, it is more difficult to "take" the speed of light than to ascend to the sky, everyone can be exposed to light all the time, but it cannot "work" for human beings, anything in the universe can only approach the speed of light, not exceed the speed of light, so it can be seen that people can only imagine creating a spaceship faster than light. Nowadays, there is a shortage of energy, and human beings cannot find other resources to replace it for the time being, so we should learn to use resources sparingly in our daily life.
Scientists have tried their best to create new energy, but new energy is far inferior to other energy sources, I believe that with the passage of time, the progress of science and technology, light energy is used by human beings, once human beings can control the energy of light at will, it means that human beings must be a high-level civilization in the universe. Today's earth has become very different from the previous earth, and various resources have been depleted, or directly affect the survival of human beings. What do you think about this?

Nothing with mass is capable of moving at the speed of light, let alone faster than the speed of light.
Because it can be seen from the unbreakable formula: energy and mass are equivalent. The energy that an object has due to its motion should be added to its mass.
For example, an object moving at 10% of the speed of light has more mass than before, but an object moving at 90% of the speed of light has more than twice the mass of normal. The closer an object is to the speed of light, the more massive it becomes. Conversely, an object can never reach the speed of light, because then the mass becomes infinite, which requires an infinite amount of energy to do according to the principle of mass and energy equivalence.

Some group velocities, phase velocities may exceed the speed of light, but they are not the same concept as photon velocity.
-
The speed of light is speed, energy is energy, and there is no relationship between the two!

Your question is very unscientific.
Just as mankind has been looking into the depths of space and searching for extraterrestrial life, Swedish scientist Syca Wensrov has revealed a magical encounter of his ownIt caused a shock in the world astronomical community, and since then, the search for the Martian village has been repeated in the primeval forests of eastern Zaire. >>>More

This cannot exist. Because the temperature inside the earth is so high, there can be no oceans.
Questioning is the starting point for innovation. All scientific discoveries begin with doubts, and Copernicus's doubts about the center of the earth prompted him to establish the theory of the center of the sun. Newton argued: >>>More
