Most of the intelligence out there must be artificial intelligence. We keep looking for critters like us living on a planet like ours, where in fact the majority of the intelligence out there is not biological. That would be my argument.

Our brains are continuing to evolve, and perhaps a few tens of thousands of years from now, our descendants will walk around with five pound brains, allowing them insights that we can't imagine.

While it may be disappointing, I have to confess to people who ask for my insights on the meaning of it all that astronomy doesn't provide any clearly useful data on matters of sin and souls.

Are we the only members of the Galaxy that can actually understand what a galaxy is? Could Homo sapiens really be the pinnacle of Creation - the cleverest critters in the cosmos? If we learn the answer is 'no,' that would affect our philosophies forever.

I'm not well-versed in the science fiction world. I'm hoping that I'll get more opportunities in it because you get to create a new world.

Around 17 to 20 years, I became, myself, a poacher. And I wanted to do it, because - I believed - to continue my studies. I wanted to go to university, but my father was poor, my uncle even. So, I did it. And for three to four years, I went to university. For three times, I applied to biomedical science, to be a doctor. I didn't succeed.

We have to realize that science is a double-edged sword. One edge of the sword can cut against poverty, illness, disease and give us more democracies, and democracies never war with other democracies, but the other side of the sword could give us nuclear proliferation, biogerms and even forces of darkness.

People think acting is just memorizing lines and doing facial expressions. No it's about traveling along a path of discovery, intention and connection.
