The speed of light!
It's like that Messianic "giant leap" in Hebrew [צעד גדול]. It equals 207, which is ohr [אור], light (Let there be light!)
The eureka effect (also known as the Aha! moment or eureka moment) refers to the common human experience of suddenly understanding a previously incomprehensible problem or concept.Matthew 24
26 Wherefore if they shall say unto you, Behold, he is in the desert; go not forth: behold, he is in the secret chambers; believe it not.
27 For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of man be.
28 For wheresoever the carcase is, there will the eagles be gathered together.
The speed of light is waaaaaay to slow for space travel.........
