![]() Lewis and Juliana Kwan from the School of Physics at the University of Sydney, have got some suggestions that fly in the face of this stuggle = quick death hypothesis” This example contradicts the claim that “Geraint F. The latter is precisely the “stuggle = quick death hypothesis,” since the one who didn’t struggle (the freefaller) experienced more time than the one who struggled (the rocketeer) This is related to one of the basic results of relativity – people in freefall experience the maximum proper time.” A check on their stop watches would reveal that the free faller would experience the most personal time in the trip. ![]() One falls inwards, while the other accelerates towards the centre for a little, then swings their rocket round and decelerates such that the free faller and the rocketeer meet and clasp hands again just before hitting the singularity. As they cross, they start identical stop watches. Suppose they cross the event horizon together holding hands. Time to you can use to deal with your spaghettification problem.Ĭonsider a race to the centre between a free faller and a rocketeer. Even after you’ve fallen into the black hole’s event horizon, there are things you can do to lengthen your harrowing journey so that you get to experience more time. ![]() “Consider a race to the centre between a free faller and a rocketeer. ![]() All you have to do, once across the event horizon, is fire your rocket for a fixed amount of time, and then turn it off and enjoy the rest of the fall.īut how long should you fire your rocket for? Lewis and Kwan show this is a simple calculation involving the mass of the black hole, how powerful your rocket is, and how fast you crossed the event horizon, easily doable on a desktop computer. So, what are you to do? Lewis and Kwan have the solution, identifying an acceleration “sweet-spot” that gives you the maximal survival time. However, Lewis and Kwan have demonstrated that in the convoluted space-time within the event horizon, such a strategy actually hastens your demise, and you’ll actually end up experiencing less time overall. In a moment of panic, you may point your rocket outwards and fire it at full thrust, keeping the engine running until you arrive at the central singularity. For a supermassive black hole, you might last a few hours. If you fall straight down into a stellar black hole, you’ll last a fraction of a second. When an unlucky victim falls into the event horizon of a black hole, they will survive for a finite amount of time. Their paper is called No Way Back: Maximizing survival time below the Schwarzschild event horizon, and it was recently accepted for publication in the Proceedings of the Astronomical Society of Australia. Lewis and Juliana Kwan from the School of Physics at the University of Sydney, have got some suggestions that fly in the face of this stuggle = quick death hypothesis. ![]() It was thought that your best strategy was to do nothing at all and just freefall to your doom.įortunately, Geraint F. The more you try to struggle, the faster your demise will come. It will occur at some point in the future, in a finite amount of proper time. Once you cross the event horizon, or Schwarzschild radius, your date with the singularity is certain. Physicists used to think that blackholes were sort of like quicksand in this situation. Since nothing, not even light can escape the pull from a black hole once it passes into the event horizon, what can you do to maximize your existence before you join the singularity as a smear of particles? Uh oh, you’re dead – not yet, but it’s inevitable. You’re hurtling through the cosmos at nearly the speed of light in your spaceship when you take a wrong turn and pass into the event horizon of a black hole. Here’s a scenario that will face many of us in the far future. ![]()
