The faster an object moves, the slower time goes. If you're moving at c (lightspeed), time stops?

Speed is not absolute, but measured from a frame of reference.

If we measure our speed from the p.o.v. of an approaching photon, we are travelling at c (lightspeed). Are we not?

As time has not stopped for us that can't be the case. Our speed (velocity) is less than c.

What frame of reference are we in then, when seconds tick bye at the normal rate, and we live for around 60 years?

some of us know the answer. most don't. not even the brainwashed marxists that emerge from today's public re-education camps..errr schools.

The No. 1 goal of that cultural Marxism, since its creation, has been the destruction of Western culture and the Christian religion. Antonio Gramsci famously laid out a strategy for destroying Christianity and Western culture, one that has proven all too successful. Instead of calling for a Communist revolution up front, as in Russia, he said Marxists in the West should take political power last, after a "long march through the institutions" – the schools, the media, even the churches, every institution that could influence the culture. That "long march through the institutions" is what America has experienced, especially since the 1960s. One of its main components was introducing sex education into Hungarian schools. Lukacs realized that if he could destroy the country's tradition

What would happen if you were in space and you breathed out?
Would your breath form bubbles or would it just be absorbed,and if it was absorbed ,what would it be absorbed by?
Space must be made of something,or else it would be anti-matter wouldn't it?

ok... so space and time are relative to each other, and we know that on Earth people can live to be 100 years old Earth time. Lets say that in space away from our Sun, from our Earth. Wouldn't we lose a standard of time and perhaps even live longer? Could our 100 years in Earth equal 1000 somewhere else?

10 base ten is pretty arbitrary. Who's to say that's the most efficient? Why not 12? Why not 7? I'm not convinced. Anybody know what is or how to find out? I'll take anything. Please, throw out speculations. Remember: ancient civilizations like the Aztecs and Sumerians used base SIXTY! (60, 60, 24 ¦ ) It might end up being as big a number as that!

Observation shows that the universe is expanding, or that space is expanding. The Big Bang theory has been confirmed.

What I want to know is couldn't the same observational results be gotten if space wasn't expanding, but rather objects within space like galaxies, were shrinking?

They would appear to ba oving away, and there would also be red shift, right?

I guess that astrophysicits know why my contention is wrong, but I don't. Any help therefore appreciated, and I don't mind *a few* long words.

A plant breeder claims that a new variety of fruit bush he has produced gives a higher yield of fruit than the variety it will replace. A random sample of 10 bushes of the new variety is grown and the yields of the bushes recorded. The old variety has an average yeild of 5.2kg/bush. It is assummed that the yield from each bush is an independent observation from a normal distribution. Test at 5% level of significance, the breeder's claim.

What do you think the null and altenative hypothesis are? Please explain!

Side question: How big is the range of the p-value(observed significance value)?
