  1. There is another driver of exploration and that is "group prestige" or "our system is better than yours so defect from your system and come to ours". The Romans and Catholics did it with building huge feats of architecture.

  3. The idea is that nature is all that there is and there's nothing beyond the natrual world but the big bang challenges that because if you go far enough back into time you realize that the material universe itself had a starting point before matter, space, and time come into existense before which there is no matter to do the causing so you have this problem that if you want to explain the orgin of the universe materialistically you're kind of stuck. All there is all there was all that there will ever be ….all there is is matter but you get to the point where matter starts ..before which you cannot pause a materialistic explanation natrualism denies there is anything beyond the physical world to bring the universe into existense thats where theism comes into the picture ..a theist can posit the existense of a creative external to the physical world and therefore offer a causal explanation where the universe came from .

  4. Sending humans to Mars would be an incredible waste of money, and also very dangerous for them. This because all the scientific exploration and experiments could be performed by robots at much lower cost and no risk for human life.

  5. Tyson is a far from being an intellectual. His take on animal rights and veganism is a complete joke. How can you be so "smart" and stupid at the same time. It's unbelievable. I would love to see him say Einstein was wrong about vegetarianism.

  6. I don't think its a good idea to send people to Mars right now. Here is why?

    No natural air
    No food
    No ecosystem

    Instead of sending people, work on making better AI robots. Then send those to Mars so that they can build some shelters and grow food so that all this is set up even before we launch to go there.
