Flavor Flav knows what time it is. At least he does for Flavor Flav. Even with all his moving and accelerating, with the planet, the solar system, getting on planes, taking elevators, and perhaps even some light jogging. In the immortal words of Kool Moe Dee. Do you know what time it is?
Didn't Einstein tell us it's all relative? Does anyone actually know what time it is? I mean, aside from figuratively, or in a political sense, or perhaps as part of rap performance from whence the power is being fought from, requiring the sick skills of a hype man wearing a clock around his neck on a big chain.
So, after all my fancy dancing and longing for a time in rap and hip hop from days gone by, I must present to you "faithful audience member" an answer in the form of your 3 least favorite words I get to deliver.
It all depends…
You have heard that everything is relative, usually we hear it from people who like to talk about "connections on many different levels", which is just nonsense.
But in physics "everything" is relative in a very particular way. Everything is relative to the speed of light, which is the same in every reference frame. Which is confusing and repeated enough that it can become meaningless.
So I'm going to do my best to explain it. If I shine a flashlight in front of me, I will measure the beam to travel at about 300,000 km/s, which is also known as the speed of light.
