If the Sun exploded, we wouldn't know about it for 8 minutes and 20 seconds. Light and gravity take that long to reach us. Then we would vaporize.
Interpretation
There is a delay in our awareness of cosmic events, highlighting the vastness of space and the limits of our perception.
Neil Degrasse Tyson's quote emphasizes the incredible distances in the universe and the finite speed at which light and gravitational waves travel. This implies that even if a catastrophic event like the Sun exploding were to occur, humanity would remain blissfully unaware for over eight minutes, underscoring both the power of the cosmos and the limitations of human perception.
In practice
In a science class discussing the nature of light and gravity.
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.
It is generally believed that our science is empirical and that we draw our concepts and our mathematical constructs from the empirical data. If this were the whole truth, we should, when entering into a new field, introduce only such quantities as can directly be observed, and formulate natural laws only by means of these quantities.
Statistical science is indispensable to modern statesmanship. In legislation as in physical science it is beginning to be understood that we can control terrestrial forces only by obeying their laws. The legislator must formulate in his statutes not only the national will, but also those great laws of social life revealed by statistics.
Almost everything that distinguishes the modern world from earlier centuries is attributable to science, which achieved its most spectacular triumphs in the seventeenth century.
I argue that for every country to have an independent fuel cycle is the wrong way to go. Because any country which has a complete fuel cycle is a latent nuclear weapons country, in the sense that it is not far from making a nuclear weapon.
I'm in favor of changing the destination of humans. There are a lot of manned missions that can be done, but not in the direction of the moon.
There is no branch of mathematics, however abstract, which may not some day be applied to phenomena of the real world.
