Prime numbers / last digit

    As is well known, in the decimal system large prime numbers can have only the final digits 1,3,5 or 9.

    I claim that it is possible that from 1000^1000^1000 (or even higher) every prime number has the final digit "1".

    If this cannot be disproved, then we know next to nothing about prime numbers.

    The thread is just maths with little logic or philosophical content. If you want to discuss it, please have a read of the site guidelines and this guide of how to write an OP.

    I'm sure there's something philosophical in what you've wrote, all you need to do is put in a bit more effort to make it come out. I'm going to close the thread.
