# Could light be a particle that is unobservable as an actual particle?

Could light be a particle that is unobservable as an actual particle because of the fact that it is traveling at the speed of light, and thus occurs at a different temporal 'dimension' because of the relativistic difference in velocity between the light 'particle' itself, and the space in which it is moving through? In other words, if I were able to throw a particle at the speed of light, it might lose observability because of the speed it was traveling?

Light is observable though. I observe it every time I open my eyes, take a picture, or feel the Sun on my skin.
Also, there is only one temporal timension, and we cannot throw a particle at the speed of light, so your question isn't answerable.

Light is observable with our eyes, yes, but it behaves like a particle, particularly in the way that it is affected by gravity. The question might be 'what happens to a particle of matter if it was hurled at the speed of light in a vacuum?'.

That cannot happen, so your question is invalid.

Physicists have complicated equations that explain the behaviour of light. It has very little to do with the English word "particle."

As far as I am concerned light is unobservable. All we can observe is what matter does when light whacks into it.

But that's how we observe all things. Light or matter whacking into things.
