At The Speed of Light

In an interview with StarTalk Radio host Chuck Nice, astrophysicist Neil deGrasse Tyson explained why photons (the particles that carry light) exist outside of time. “…As you increase your speed, time ticks more slowly for you than it does for anyone who is watching you,” he said on StarTalk Radio. “This is the relativity of time. This is well known. We have measured this. It is not just your clock that is clicking slower, your metabolism is unfolding more slowly, your brain synapses are firing more slowly, everything about you is slowing down.”

“Photons, which is the carrier of light, exists at the speed of light. It doesn’t accelerate from zero to speed of light in 3.4 seconds. It exists at the speed of light, and because of it exists at the speed of light, any watch that it is carrying never ticks, which means if you are the photon… you will slam into whatever you are destined to hit, as far as you are concerned, instantaneously.”

He went on to explain that they know neutrinos travel slower than the speed of light because they change states between two different kinds of neutrinos, which would only be possible if neutrinos experienced the passage of time. Just thought I’d blow your mind for a change.
