There is no scientific reason to think that we, even with space travel, are going to survive as a species for ever, certainly not by biting off the hand that feeds us, which is exactly what we are doing.

The vast distances that separate the stars are providential. Beings and worlds are quarantined from one another. The quarantine is lifted only for those with sufficient self-knowledge and judgment to have safely traveled from star to star.

We agree that man was not created to survive in space.

There's going to be space travel at some point.

how much does it cost now for a mock space travel in the planetarium? That will b the future cost of space travel, Isnt it?

future space travel = Your bus and taxi fare here is how u get the same idea that i have. goto any nearest planetarium and see the show. at the end of it just say 2 questions. how was the space travel? HOw is the space ship?
