1.400,000 people worked on the American space program – how would you fool all of them?
2.Yes, a Hollywood could be done in the desert, but how could anyone interface this production into the systems so as to fool 300 experienced controllers in the two massive control centers, and over the course of 7 years of Apollo.
3.Why haven’t we been back to the moon? People who naively believe the hoaxers, have no idea what it took to get men safely to the moon. The 360 foot tall Saturn V rocket was the only rocket ever built to take men beyond Earth’s orbit. When budget cuts hit, the Saturn V was never needed any more
4.It took years and billions of dollars to develop the LEM – Lunar Lander. If the hoax believers took the time to read the history, and understand the problems, they would see that to land men safely on a solid body, with no air (all landings on Earth use the air – parachutes into the ocean and the Shuttle becomes an airplane), took a massive amount of development.

That, is, something with more than 1 dimension. If so, couldn't I "push" one end of it and cause movement instantaneously at the other end? (Please don't *assert* the fact that information can't be transported instantaneously, obviously I'm looking or *implications* of that *theory*.)

well see the sun is just a big star and when a star goes out it creates a black hole and a pull in the universe and pulls anything around it in
including light . The sun is the biggest star in our solar system so what could happen if it did go out ? what would happen to the planets? would they get pulled in ?
