Do you think it's possible that Prof. Hawking is not really that intelligent and he is fed all his information from some guy sitting at a PC all day long, i mean he hasn't invented any thing to make our lives easier at least einstein split the atom, who cares about a journey through space and time?

On the cardinality of certain set of primes?

A prime number p with n digits is called an embedded prime if it remains prime after eliminating the leftmost i digits of p, for i = 0,...,n-1. For example:

137 is an embedded prime because
-137 is prime
-37 is prime
-7 is prime

or

45197 is an embedded prime because
-45197 is prime
-5197 is prime
-197 is prime
-97 is prime
-7 is prime

But, 4127 is not an embedded prime because
-4127 is prime
-127 is prime
-27 is NOT prime
-7 is prime

Is the set of all embedded primes infinite? If not, what is the largest embedded prime? If there is a largest, then since any n digit embedded prime is an extension of an n-1 digit embedded prime, this question seems suitable to be answered by a computer program. However, I have neither the means nor know-how to experiment.

Space, Time,?

It is said that our combined speed through space and time is always precisely equal to the speed of light. Which means that the faster you move through space the slower you move through time; and visa versa. Also, the only thing that isn't affected by time is a moment; because if a moment changes it then becomes another moment. So what I am asking is; what is the best explanation of time and space? And the part it plays in our lives? After all everyone’s "now" is completely different then everyone else’s.
