Some particles, like photons and gravitons, are believed to ALWAYS travel at the speed of light. Particles, or larger amounts of matter, that move at a slower speed can't be made to travel at the speed of light - according to the Special Theory of Relativity, that would require an infinite energy.
What else can I help you with?
When train is travell with speed of light nd we put a mirror in front of me then what will image formed?
An object such as a train simply CANNOT travel at the speed of light. You can investigate what happens when it moves close to the speed of light.
Does matter turn into light when achieving the speed of light?
No, matter does not turn into light when achieving the speed of light. As an object with mass accelerates towards the speed of light, its energy increases, but it does not transform into light. It would require an infinite amount of energy to accelerate an object with mass to the speed of light.
What should be the mass of anything at the speed of light?
Anything that has any mass when it's at rest would have infinite mass at the speed of light.
If you were travelling faster than light could you still see an object in front of you?
You cannot travel at the speed of light. Period.
An object moves in light speed will shred its mass?
An object that normally doesn't move at light speed (so, this doesn't include photons for example) CANNOT move at the speed of light. As it approaches the speed of light, its mass will get higher and higher (and tend towards infinity); as will the energy required to continue speeding it up.
Can an accelerating object have zero speed?
No, an accelerating object cannot have zero speed. Acceleration is the rate at which the speed of an object changes over time. If an object is accelerating, its speed is increasing or decreasing, but it cannot be zero.
Do you have to add the speed of an object to the speed of light?
No, because according to Einstein, there is nothing that can travel faster than the speed of light. For example, if there is a headlight on the front of a train that is travelling 60 km/h, the light coming from the front of the train is still only going at the speed of light despite the speed of the train.
Can light exceed its normal speed?
No, according to current scientific understanding, light travels at a constant speed in a vacuum, known as the speed of light, which is approximately 299,792 kilometers per second. This speed is a fundamental constant of nature and cannot be exceeded by light or any other object.
Why can an object with a nonzero mass never travel as fast as the speed of light?
An object with mass cannot travel at the speed of light because as it approaches the speed of light, its energy and momentum increase infinitely, requiring an infinite amount of energy to accelerate further. This is not possible due to the limitations of mass and energy in the universe.
If a beam of light is emitted from a light source that is moving backwards at the speed of light would light be emitted?
It is not possible for any physical object to accelerated to the speed of light. But in one particular extreme it is possible to slow the speed of light according to the Bose-Einstein Condensate. The question better stated would be "Would an independent observer see light emanating from a source that is traveling backwards at the speed of light?" Yes. Light always travels at the same rate. No matter how fast you are traveling, any light that you emit will always travel at a constant rate. (note that it's not possible for a physical object to actually travel at the speed of light in a vacuum).
What do you need to travel at the speed of light?
To travel at the speed of light, you would need to have an infinite amount of energy, which is currently not possible with our current technology and understanding of physics. Additionally, as per the theory of relativity, an object with mass cannot reach the speed of light.
Can information travel faster than the speed of light?
No, according to the theory of relativity in physics, information cannot travel faster than the speed of light in a vacuum. This is because as an object with mass accelerates towards the speed of light, its energy increases towards infinity, making it impossible to exceed the speed of light.
