Velocity is real, distance is real, time is how we've decided to describe their relation. Physically and philosophically, the "idea of time" isn't real. It just helps us describe our reality.
velocity is defined as distance over unit time so I’m not sure how you square that circle

#36To me it's pretty intuitive that time isn't real (outside of being a concept). We just use time as an elaborate way to explain our movement through distances (and how fast or slow we cover those distances), that's about it. The twin paradox[1] does a good job of explaining this. There's no discernable difference between today and lets say, arbitrarily, 1984. The only difference is our movement through that spatial di…
Agreed! In my mind, to go back in time is to put all particles or whatever fundamental components back in the same place and state as they were previously. Thus, that would include the particles that make up you as well. How would you ever do that and if you did, how would you notice and is it really the past or just now with a replicated state?

Given that the speed of light directly relates time and distance in (to the best of our extremely precise measurements to date) an absolute manner, then if time doesn't exist, neither does distance. Also, as TFA mentions any dismissal of time as a concept must also deal with thermodynamics.
The speed of light is still just the movement of something over a measured distance.

#38Time is the direction in which entropy always increases. It's the most real thing there is.

As I approach 40, a year feels about as long as a month did when I was elementary-school aged. I worry that if the current rate-of-increase continues, my last decade will feel weeks long.
I think the answer to this is to do more interesting things on a regular basis. If every weekend you do something different, then the month feels longer than when you stay home every weekend.
