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.
Interpretation
This quote suggests that life on Earth may have originated from life on Mars, implying a connection between the two planets.
Neil Degrasse Tyson's quote explores the fascinating possibility that life on Earth could be linked to life that once existed on Mars. It raises intriguing questions about the origins of life in the universe and suggests that all life on Earth might share a common ancestry with Martian organisms, emphasizing the interconnectedness of life across planets.
In practice
In a science presentation discussing the origins of life on Earth.
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.
You don't have money, you can't do science. But that's part of the price that I pay.
In the long run, curiosity-driven research just works better... Real breakthroughs come from people focusing on what they're excited about.
Accurate and minute measurement seems to the non-scientific imagination, a less lofty and dignified work than looking for something new. But nearly all the grandest discoveries of science have been but the rewards of accurate measurement and patient long-continued labour in the minute sifting of numerical results.
In the history of physics, there have been three great revolutions in thought that first seemed absurd yet proved to be true. The first proposed that the earth, instead of being stationary, was moving around at a great and variable speed in a universe that is much bigger than it appears to our immediate perception. That proposal, I believe, was first made by Aristarchos two millenia ago ... Remarkably enough, the name Aristarchos in Greek means best beginning.
Science has a culture that is inherently cautious and that is normally not a bad thing. You could even say conservative, because of the peer review process and because the scientific method prizes uncertainty and penalises anyone who goes out on any sort of a limb that is not held in place by abundant and well-documented evidence.
My dear Kepler, what would you say of the learned here, who, replete with the pertinacity of the asp, have steadfastly refused to cast a glance through the telescope? What shall we make of this? Shall we laugh, or shall we cry?
