Here's why:
* Speed of Light is a Limit: The speed of light in a vacuum (approximately 299,792,458 meters per second) is the absolute speed limit in the universe. Nothing with mass can reach this speed.
* Alpha Particles Have Mass: Alpha particles are made up of two protons and two neutrons, giving them a significant mass.
* Alpha Particle Speeds: While alpha particles are ejected with high speeds, these speeds are always less than the speed of light. The exact speed depends on the radioactive decay process and the specific element involved, but it typically falls in the range of a few percent of the speed of light.
Key takeaway: No particles with mass can travel at the speed of light.
