How Fast Can You Travel And Stay Alive?

okay place those goggles over your eyes strap in and don't forget to hold on tight we're gonna see how fast we can really go long legs on a tall yet muscular frame not exactly the norm when compared to the shorter builds of short distance runners but the fastest man alive makes it look easy to move that fast so far the fastest anyone has run is just over 27 miles per hour a speed reached briefly by sprinter usain bolt at the halfway point of his world record 100 meter dash and humans can go even faster the top speed we could reach may come down to how quickly the muscles in our body can move our muscles should be able to reach speeds as fast as 40 miles per hour the reason we can't do it is that we're in the air for too long our limbs can only take a certain amount of force when they strike on the ground that's why on skates you're able to outpace a runner gliding allows for more traction what would make us a lot faster is simple ish longer legs really wide hips or extra legs like an insect i give running on all fours a truck it would be fun at least in 2016 speed records weren't just broken on the running track they were broken on the ski slopes in france the world record for downhill skiing belongs to an italian ski instructor and a mountain guide in 2016 assisted only by gravity the instructor set a human land speed record of around 158 miles per hour skiing across the zone near the bottom of a course in just over two seconds wow i can barely stand up on skis let alone move half that fast the fastest a tiger beetle can sprint is up to five miles per hour doesn't sound that fast really but consider this it's covering 120 of its body lengths in a single second for comparison bolt covers about six body lengths per second to match this beetle he'd have to run about 480 miles per hour that's twice as fast as a peregrine falcon tiger beetles have extremely sharp eyesight for insects but while they're running the world turns into a featureless smudge this means the beetle has to stop every now and then and see where it's going so they're pretty fast but there's a mite a special mite whose speed is equivalent to a human running roughly 1 300 miles per hour at its quickest this sesame seed sized mite can move 322 body lengths per second wow most cats run zero times their body length for the majority of the day yeah well we're not going to be moving that fast anytime soon we've got a few tricks up our sleeve thanks to our big brains we can use technology the fastest we've ever traveled on land over one mile is 763 miles per hour it was done back in 1997 in nevada in a thrust ssc that's a big improvement from the first holder of the record in 1898 a frenchman hit the actually pretty amazing speed of 39 miles per hour in his electric powered car through the air we've traveled at mach 3.3 that's around 2100 miles per hour it's all thanks to the fastest jet aircraft in the world the lockheed sr-71 black bird amazingly this plane doesn't have a top speed the only thing limiting its speed is temperature if it was allowed to fly as fast as it wanted it would literally melt in mid-air on water the speed record is just over 275 knots or a little over 317 miles per hour a jet powered hydro plane called the spirit of australia did it back in 1978 not bad if you want to get to your favorite fishing spot quickly in 1896 there weren't that many driving laws but still walter arnold decided to break one of them and became the first man in history to receive a speeding ticket the speed limit at the time was two miles per hour you could have walked faster and most people did but that was too slow for arnold who decided to race through the town at eight miles per hour eventually he was caught and received a one shilling fine quite hefty for the time a man named felix was taken over 127 thousand feet into the edge of space in a balloon that when fully inflated was about the size of the statue of liberty having no choice but to jump out he eventually reached the fastest free fall speed ever 843 miles per hour in a specially designed suit of course landing back on solid ground in just over nine minutes he became the first person to break the sound barrier in free fall the fastest speed a human has ever traveled is around 25 000 miles per hour the crew of apollo 10 reached this on may 26 1969 this was also the highest speed ever reached by a manned vehicle are you feeling the hankering for speed yet good news the earth rotates once roughly every 24 hours math math math this means that the earth and you are spinning at around 1 000 miles per hour it's not including how fast we're all moving through space on this giant rock we're zipping along at 18 miles per second that's 67 000 miles per hour through the dark vacuum of space our sun and the milky way appear to be moving at an average speed of 448 000 miles per hour through space while that sounds extremely fast and it is it still take about 230 million years to travel all the way around the milky way so you're probably moving a lot faster than you thought you were but there's a good reason you're not a human puddle right now speed obviously isn't the issue the real issue is acceleration changes in speed are expressed in g forces which just means the acceleration of an object relative to earth's gravity if you're sitting on the sofa you're experiencing one g now most of us can withstand up to four to six g's like on a roller coaster some pilots manage up to about nine g's for a second or two but sustained g-forces are a big problem some pilots wear special high g suits and are trained to flex their torso muscles to keep blood from whooshing out of their heads and into their legs they can still operate their aircraft properly at about 9 g's the record for temporary gs is an amazing 82.6 g's riding a rocket-powered sled backward in 1958 eli beating junior hit the brakes and stopped in a tenth of a second as part of testing for space travel blacking out but only suffering back bruises it was a remarkable demonstration of the body's resilience to short bursts of deceleration more than 100 years ago a super famous scientist named einstein came up with an idea called relativity there was an experiment that tested this out with two clocks set to the exact same time one clock stayed on earth while the other flew on a commercial plane after the airplane returned from its trip around the world the two clocks were compared the clock on the fast-moving plane was slightly behind the other one so yes time travel is a real thing if you're going faster than another object now another place time slows down is when you're in line at the checkout stand at the supermarket but hey it's all relative the safest place to test high-speed travel is space it's an empty vacuum after all but imagine speeding through space anything the size of a grain of sand would become a high speed projectile the real danger though would be small hydrogen atoms just floating around the hydrogen would shatter into particles that would pass into the ship it wouldn't be pretty your spacecraft would also heat up really quickly too sounds dangerous you go first
