Question

Why anything can't travel faster than light? 5mark

Open in App
Solution

Every particle in our universe (including photons) moves or ‘swim’ through what scientists call “the Higgs field”. As a result of this interaction, particles acquire their mass. Different particles interact with the Higgs field with different strengths, which is why some particles are heavier (have more mass) than others. Photons move through but do not interact at all with the Higgs field.

Since photons don’t interact with the Higgs field, it means they aren’t bound by any speed limit. They’re free to move at the fastest possible speed – their own “light” speed.

Nothing can travel faster than light because the speed of light can be thought of as infinite speed. To match or exceed it would be to go infinity miles per second/hour. A loop-hole does in fact exist, however. The loop-hole requires control or warping of the fabric of spacetime itself.
