Explain about this please
hi,
Is it so if a particle travels in a speed of light then its mass is considered as Zero?

vivekhere said:Hi,
a matter travels more than a speed of light can be in its future.
can u tell me how this is satiesfied?
There is no such theory. It is true that the Lorentze transformation equations give a negative time (which might be considered moving back in time) if you put speed v greater than c, but there is no evidence that that has any physical significance.vivekhere said:Hi,
I have another doubt.
As u all said only the massless objects can travel in the spped of light then there is one theory which states if a matter travels more than a speed of light can be in its future.
can u tell me how this is satiesfied?
? Stand beside a road and watch one car pass another! Am I misunderstanding your question?vivekhere said:hi,
ofcourse i understand that. but i want to ask another thing how a particle in Earth can travel in lesser speed than other particle.

The mass of particles traveling at the speed of light is a complex concept in physics. According to Einstein's theory of relativity, as an object approaches the speed of light, its mass increases infinitely. However, this is only applicable to objects with mass and not to particles such as photons, which have no rest mass and always travel at the speed of light.
Particles do not have mass when traveling at the speed of light. This is because, according to Einstein's theory of relativity, the mass of a particle increases infinitely as it approaches the speed of light. However, particles traveling at the speed of light have no rest mass, meaning they have no mass when at rest. Their mass is a result of their energy, as described by the famous equation E=mc².
The mass of particles traveling at the speed of light plays a crucial role in the structure and dynamics of the universe. The energy and mass of particles contribute to the total mass and energy of the universe, which affects the expansion rate and the overall evolution of the universe. In addition, the concept of mass-energy equivalence plays a significant role in understanding the Big Bang theory and the formation of the universe.
No, particles with mass can never reach the speed of light. According to Einstein's theory of relativity, as an object approaches the speed of light, its mass increases infinitely, making it impossible to reach the actual speed of light. However, particles with no rest mass, such as photons, always travel at the speed of light.
The speed of light plays a crucial role in modern physics, as it is the maximum speed at which particles can travel. This speed sets the limit for how fast information and energy can be transmitted, and it is used in various theories and equations in physics, such as Einstein's theory of relativity and Maxwell's equations of electromagnetism. The discovery of particles traveling at the speed of light has also led to the development of technologies such as fiber optics and lasers.
