We all move at the Speed of Light

Easily the best video I've seen about Space-time


 Is it possible to go faster than the speed of light? Would this mean going back in time? What is so fundamental about this precise speed?

  1. More reification of abstractions…

    Just because STEM people can use the abstractions in wave theory which includes the abstractions of period T and frequency 1/T and the associated electricity and electromagnetism towards our purposes doesn’t mean that light is speeding thru outer space like a rocket ship…

    This is the same thing the monetarist morons do with their “money is real!” BS..

  3. Well the general topic is light, so I'll just add that you should not expose your roasted coffee beans to direct light -- in other words, no roasted coffee beans in glass jars on your kitchen counter.

    Still, you know, I just had another sub-par cup of coffee this morning. What a lousy way to start your day :( So, that's it for me. I'm getting myself a home coffee roaster and roasting my own coffee. No more stale/dead coffee, no siree bob.

  4. Tell the truth now -- didn't anyone else here google the word "reification."?

    1. I've come across it a number of times, but I had forgotten what it means as it's not used very often.

  5. I remember I think it was Ralph said one time here somebody was “taking the piss” … I thought he meant somebody was urinating..

    We don’t have that figurative phrase over here… so you have to take it literally…. same with abstractions if you don’t understand them you have to think they are real… “money” is real… period and frequency are real… etc…

  8. Take the piss out of Psaki... if you want to pronounce her name correctly.

    1. Not to piss on your comment above, but, for the record, "Psaki" is the feminine form of "Psakis." Her father is Greek-Amerrican.

  11. I'd hate to trace my ancestry all the way back to my "great, great...great grandfather" only to find out that he took part in the Fourth Crusade (1204 A.D.). That would be a bummer... finding out you have Latin blood :(
