I don't disagree with Einstein's notion. I disagree with your description of Einstein's notion.<quoted text>
You like to quote Einstein a lot, yet you apparently disagree with his own notion that space time is made of four identical dimensions, one of them being time. Please explain if you can ..... I'll wait.
"Space and time are modes by which we think, not conditions under which we live." Time the time that we know through clocks and calendars was invented. Space and time are models by which we think, not conditions under which we live.
Albert Einstein - Encyclopaedia Britannica
Time has no independent existence apart from the order of events by which we measure it.
Albert Einstein - Harpers
Relax, take a deep breath and focus on the words "no independent existence", bubba.
Let me know when you finally get it.
BTW Richard Feynman described time as a "direction" like you did in your post, i.e. up, down.
