you say "is that intuitive?" intuition isnt the same for all. in fact it is relative lol no pun intended. einsteins thoughts that the speed of light is the same for all observers and the spaceman traveling at high speed will age slower and that space and time were inseparable WERE INTUITIVE to him.
f=ma is not intuitive to a retarded person.
you might ask if we would arrived at relativity today without einsteins intuition.
my guess is yes but its possible we might still not have come to relativity without einstein.
either way, einstein proves how far iq and intuition can take you.
