I once watched a science fiction movie from way back, where a theory was proposed for a spaceship that travels at the speed of light. Though, I know the possibility is very bleak but in technology, anything is possible.

More so, there are particles that travel at a near speed of light as you said. I also once read about another hypothetical particle (the tachyon) that is believed to have a speed more than that of light.

Nice piece buddy. Thanks for sharing
