If Mars formed life, then life on Earth could have been seeded by life on Mars, making every life form on Earth descended from Martians.
-
The only way you can invent tomorrow is if you break out of the enclosure that the school system has provided for you by the exams written by people who are trained in another generation.
-
My view is that if your philosophy is not unsettled daily then you are blind to all the universe has to offer.
-
The Universe is under no obligation to make sense to you.
-
I think that intelligence is such a narrow branch of the tree of life - this branch of primates we call humans. No other animal, by our definition, can be considered intelligent. So intelligence can't be all that important for survival, because there are so many animals that don't have what we call intelligence, and they're surviving just fine.
-
Pretty much every plant and animal alive today is the result of eons of natural cross-breeding.
-
Innovations in science and technology are the engines of the 21st-century economy; if you care about the wealth and health of your nation tomorrow, then you'd better rethink how you allocate taxes to fund science. The federal budget needs to recognize this.
-
The partisanship surrounding space exploration and the retrenching of U.S. space policy are part of a more general trend: the decline of science in the United States. As its interest in science wanes, the country loses ground to the rest of the industrialized world in every measure of technological proficiency.
-
It may be that our cosmic curiosity... is a genetically-encoded force that we illuminate when we look up and wonder.
-
That makes me want to grab people on the street and say, 'have you heard this?'
-
Do you realize that if you fall into a black hole, you will see the entire future of the Universe unfold in front of you in a matter of moments and you will emerge into another space-time created by the singularity of the black hole you just fell into?
-
If your ego starts out, 'I am important, I am big, I am special,' you're in for some disappointments when you look around at what we've discovered about the universe. No, you're not big. No, you're not. You're small in time and in space. And you have this frail vessel called the human body that's limited on Earth.
-
It's always interesting just to see how the human mind is relating to the natural universe, and what we try to make of it just so we can believe we understand what's going on.
-
The chances that your tombstone will read 'Killed by Asteroid' are about the same as they'd be for 'Killed in Airplane Crash.'
-
Everyone should have their mind blown once a day.
-
When a president promises something beyond his years in office, he is fundamentally unaccountable. It is not his budget that must finish the job. Another president inherits the problem, and it becomes a ball too easily dropped, a plan too easily abandoned, a dream too readily deferred.
-
The humblest person in this world is the astrophysicist. Because we are face to face with our ignorance every single day.
-
I'm baffled all the time. We don't know what's driving 96% of the universe. Everybody you know and love and heard of and think about and see in the night sky through a telescope: four percent of the universe.
-
I try to show the public that chemistry, biology, physics, astrophysics is life. It is not some separate subject that you have to be pulled into a corner to be taught about.
-
All the traditional STEM fields, the science, technology, engineering, and math fields, are stoked when you dream big in an agency such as NASA.
-
Somehow it's O.K. for people to chuckle about not being good at math. Yet if I said, 'I never learned to read,' they'd say I was an illiterate dolt.
-
We think scientific literacy flows out of how many science facts can you recite rather than how was your brain wired for thinking. And it's the brain wiring that I'm more interested in rather than the facts that come out of the curriculum or the lesson plan that's been proposed.
-
Most of what Einstein said and did has no direct impact on what anybody reads in the Bible. Special relativity, his work in quantum mechanics, nobody even knows or cares. Where Einstein really affects the Bible is the fact that general relativity is the organizing principle for the Big Bang.
-
Even with all our technology and the inventions that make modern life so much easier than it once was, it takes just one big natural disaster to wipe all that away and remind us that, here on Earth, we're still at the mercy of nature.
