There is no known particle that can travel faster than the speed of light in a vacuum. This is a fundamental principle of Einstein's theory of special relativity.

The speed of light in a vacuum (approximately 299,792,458 meters per second) is the universal speed limit for all particles with mass.

Here's why:

* Energy and mass are equivalent: According to Einstein's famous equation E=mc², energy and mass are interchangeable.

* Infinite energy: To accelerate a particle with mass to the speed of light would require an infinite amount of energy. This is simply not achievable.

While there have been some experimental observations that seemed to suggest particles traveling faster than light (like the OPERA experiment in 2011), these results were later found to be due to measurement errors.

The speed of light remains a fundamental constant in our understanding of the universe.
