Back in the old days religion slowed science but the main factor slowing science these days is politics.

The pope doesnt have the power to say the world isnt round anymore.

Space the final frontier. Of course the universe is infinite whats so hard about that. Its not like the planets are bubbles in a soda pop bottle. Space contains everything dont expect to run into a wall in space because space contains the wall. Just because everything we know of is contained within something else we can see or touch many people assume Space has to be contained some how, but its us that are contained in space. We are in an infinite dimension. particulate matter in a walless, floorless, ceilingless closet. Space is contained in Space would also be a false statement suggesting there were layers or levels of space. Space just goes on. No walls, ceilings, or floors.

space/universe two words that mean the same thing. Infinite openness. The hard part of explaining this is we dont have the right words in are language.
