What if we could travel at the speed of light? We’re still a long way off, but tech used in spacecraft could one day let us travel from New York to Los Angeles in just one second.
Light is the fastest thing that exists. It travels at 186,000 miles per second. As such, it can travel from the Earth to the Moon in just over a second. Creating vehicles that reach the speed of light isn’t going to happen anytime soon. There are just too many variables to nail down. However, the tech that we use in spacecraft could let us harness a small percentage of that speed. That could be enough to change how we travel altogether.
Traveling at a percentage of something might not sound like much. However, even at just one percent of the speed of light, we’d be able to travel close to seven million miles per hour. That means it would take a little over a second to travel from New York to Los Angeles. That’s roughly 10,000 times faster than traveling on a commercial jet.
Of course, harnessing that power isn’t going to be easy. While scientists are working on things like warp drives the tech we already use in spacecraft could give us a chance to achieve faster speeds.
In 2010, we started using things called solar sails on some spacecraft. The idea behind solar sails is to capture the power of light from the sun and use it similar to how normal sails use wind. There’s a lot of complex math behind the tech, but if we were able to transition it to more commercial transports, we could have a breakthrough in how we travel.
Solar sails are essentially just thin sheets of plastic that attach to the vehicle. They use the sunlight they capture to push them forward, and some scientists believe they could one day propel spacecraft to 10 percent the speed of light.
