No astrophysicist would deny the possibility of life. I think we're not creative enough to imagine what life would be like on another planet. Show me a dead alien. Better yet, show me a live one!
Interpretation
The quote expresses skepticism towards our current understanding of extraterrestrial life and highlights the limitations of human imagination in visualizing it.
Neil Degrasse Tyson's quote emphasizes the openness of the scientific community to the possibility of life beyond Earth, challenging the notion that we know everything there is to know about existence in the universe. It suggests that our creativity and imagination may fall short when it comes to conceptualizing what life forms could exist on other planets, urging us to seek tangible evidence of such life rather than dismissing the idea altogether.
In practice
In a discussion about the potential for life in our universe during a science lecture.
The problem is that many people operate on the assumption that NASA should go to Congress every year with hat in hand and justify it every year. Well, I see it as the greatest economic driver that there ever was. Economic drivers don't need justification.
The press still thinks [global warming] is controversial. So they find the 1% of the scientists and put them up as if they're 50% of the research results. You in the public would have no idea that this is basically a done deal and that we're on to other problems, because the journalists are trying to give it a 50/50 story. It's not a 50/50 story. It's not. Period.
As a scientist, I want to go to Mars and back to asteroids and the Moon because I'm a scientist. But I can tell you, I'm not so naive a scientist to think that the nation might not have geopolitical reasons for going into space.
In just one year, the expenditure of of the U.S.'s military budget is equivalent to the entire 50-year running budget of NASA combined.
One of my great laments is that education today seems to have... be less about passion and more about process, more about tactic or technique.
Lots of people think, well, we're humans; we're the most intelligent and accomplished species; we're in charge. Bacteria may have a different outlook: more bacteria live and work in one linear centimeter of your lower colon than all the humans who have ever lived. That's what's going on in your digestive tract right now. Are we in charge, or are we simply hosts for bacteria? It all depends on your outlook.
The theory of our modern technic shows that nothing is as practical as theory.
It is better to have 100 functions operate on one data structure than to have 10 functions operate on 10 data structures.
It's often better to read first-rate science fiction than second-rate science - it's far more stimulating, and perhaps no more likely to be wrong.
I would suggest that science is, at least in my part, informed worship.
There could be more to the universe than the three dimensions we are familiar with. They are hidden from us in some way, perhaps because they're tiny or warped. But even if they're invisible, they could affect what we actually observe in the universe.
A lot of scientists hate writing. Most scientists love being in the lab and doing the work and when the work is done, they are finished.
