Quote by Stephen Hawking

“On September 14, 2015, the LIGO gravitational-wave detectors (built by a 1,000-person project that Rai and I and Ronald Drever co-founded, and Barry Barish organised, assembled and led) registered their first gravitational waves. By comparing the wave patterns with predictions from computer simulations, our team concluded that the waves were produced when two heavy black holes, 1.3 billion light years from Earth, collided. This was the beginning of gravitational-wave astronomy. Our team had achieved, for gravitational waves, what Galileo achieved for electromagnetic waves. I am confident that, over the coming several decades, the next generation of gravitational-wave astronomers will use these waves not only to test Stephen’s laws of black hole physics, but also to detect and monitor gravitational waves from the singular birth of our universe, and thereby test Stephen’s and others’ ideas about how our universe came to be. During our glorious year of 1974–5, while I was dithering over gravitational waves, and Stephen was leading our merged group in black hole research, Stephen himself had an insight even more radical than his discovery of Hawking radiation. He gave a compelling, almost airtight proof that, when a black hole forms and “and then subsequently evaporates away completely by emitting radiation, the information that went into the black hole cannot come back out. Information is inevitably lost.”

Stephen Hawking was a renowned British theoretical physicist known for his contributions to the fields of black hole theory and cosmology. Born on January 8, 1942, he overcame the challenges of ALS to become a global icon of science and perseverance. more

“In the far future, which promises to be vastly longer than our past (like a googolplex of years to our future versus 13.8 billion years to our past), all of the stars in the universe will have run out of fuel. Those that can will collapse to black holes; eventually everything will fall into stellar-mass black holes, and those black holes will fall into supermassive black holes, and then all of the black holes in the universe will eventually vaporize into Hawking radiation. This will take a very long time. ("Eternity is a very long time, especially towards the end.") All of the Hawking radiation will dissipate in an ever-expanding cosmos, unable to fill the swelling void, and the light in the universe will go out. Eventually, ever particle will find itself alone, no bright sky above, no luminous solar systems below. For now, we're here and the skies are bright, if somewhat quite. The gamble is that the skies aren't silent.”

“Something hit me very hard once, thinking about what one little man could do. Think of the Queen Mary — the whole ship goes by and then comes the rudder. And there's a tiny thing at the edge of the rudder called a trimtab. It's a miniature rudder. Just moving the little trim tab builds a low pressure that pulls the rudder around. Takes almost no effort at all. So I said that the little individual can be a trimtab. Society thinks it's going right by you, that it's left you altogether. But if you're doing dynamic things mentally, the fact is that you can just put your foot out like that and the whole big ship of state is going to go. So I said, call me Trimtab.”

“There needs to be an intersection of the set of people who wish to go, and the set of people who can afford to go...and that intersection of sets has to be enough to establish a self-sustaining civilisation. My rough guess is that for a half-million dollars, there are enough people that could afford to go and would want to go. But it’s not going to be a vacation jaunt. It’s going to be saving up all your money and selling all your stuff, like when people moved to the early American colonies...even at a million people you’re assuming an incredible amount of productivity per person, because you would need to recreate the entire industrial base on Mars. You would need to mine and refine all of these different materials, in a much more difficult environment than Earth. There would be no trees growing. There would be no oxygen or nitrogen that are just there. No oil.Excluding organic growth, if you could take 100 people at a time, you would need 10,000 trips to get to a million people. But you would also need a lot of cargo to support those people. In fact, your cargo to person ratio is going to be quite high. It would probably be 10 cargo trips for every human trip, so more like 100,000 trips. And we’re talking 100,000 trips of a giant spaceship...If we can establish a Mars colony, we can almost certainly colonise the whole Solar System, because we’ll have created a strong economic forcing function for the improvement of space travel. We’ll go to the moons of Jupiter, at least some of the outer ones for sure, and probably Titan on Saturn, and the asteroids. Once we have that forcing function, and an Earth-to-Mars economy, we’ll cover the whole Solar System. But the key is that we have to make the Mars thing work. If we’re going to have any chance of sending stuff to other star systems, we need to be laser-focused on becoming a multi-planet civilisation. That’s the next step.”
