According to our current understanding of physics, particles with mass cannot travel faster than the speed of light in a vacuum, which is approximately 299,792,458 meters per second (or about 186,282 miles per second). This limit is a fundamental concept in Einstein's theory of relativity, known as the "speed of light barrier."
As an object with mass accelerates towards the speed of light, its energy increases, and its mass appears to increase as well. As it approaches the speed of light, the amount of energy required to continue accelerating becomes infinite. This means that it would take an infinite amount of energy to propel a massive particle to or beyond the speed of light, making it impossible for such particles to achieve or exceed light speed.
However, it is essential to note that particles without mass, such as photons (particles of light), do indeed travel at the speed of light. They have no rest mass, and their behavior is governed by the principles of special relativity.
So, based on our current understanding, particles with mass cannot exceed the speed of light, while massless particles travel at the speed of light.
