Atomic clocks left high in orbit around the earth have apparently slowed down. At such high speeds the clocks have been known to slow down. When brought back to Earth they are slower than they should be. Atomic clocks should remain accurate for millions of years. Also I've read that Astronauts living in space for a prolonged period of time are technically younger (I mean by fractions of millions of seconds but apparently this is true because of the massive speeds over such a long period). My question to you, is it true? I'm sorry if this sounds crazy but I read this recently and I was wondering if this is scientifically correct. Time travel has been asked about several times here and I'd like a professional opinion.

I'm hoping for more of a scientific explanation than philisophical... Even if its just really good science for why we cant know. Or what is speculated. But I'll take some interesting philosophy too.

I want to know how to calculate how many possible combinations of 6 symbols out of 39 symbols can be made
Each symbol can only be used once in each combination (no AAAABC or ABBBBC)
You can't have the same combination twice, just with a mixed up order (ABCDEF, BDEACF, and FEDACB would all count as one, or the same combination)
It would be great if you could prove to me how/why the formula is or number of combinations you come up with is correct
Thank you a lot

if there are 7 exclusions in a dna test that means there are 9 inclusions. Would that explain similarities between people? What is the margin of difference before declaring an exclusion?

I would be lead to believe that a pyramid would be the best, because the design would spread the load out equally throughout the structure. Give me your opinions with reasons why, possibly cited sources.

A gnat has no more value than a human baby. They are both worth nothing because they have come into being for no ultimate purpose, they are here for no ultimate purpose and they go to no ultimate purpose. The only worth or value is what is subjectively given to either by someone else. There is no such thing as intrinsic worth in a non creator God universe.
