How Close To The Speed Of Light Can We Travel?

Can humans travel at the speed of light?

“There is no real practical limit to how fast we can travel, other than the speed of light,” says Bray. Light zips along at about a billion kilometres per hour. Therefore, humans should – in theory – be able to travel at rates just short of the “Universe’s speed limit”: the speed of light.

How fast can we travel in space with current technology?

For comparison, the Voyager 1 spacecraft, launched back in 1977, is currently traveling at about 38,000 mph (61,000 km/h), according to NASA — less than 10 percent of the Parker Solar Probe’s peak speed.

What happens if we travel at the speed of light?

No, we cannot travel at the speed of light. You see, if an object travels at the speed of light, its mass will increase exponentially! Consider this… the speed of light is 300,000 kilometers per second (186,000 miles per second) and when an object moves at this speed, its mass will become infinite.

Can we travel a light year?

This duration is a bit of a problem, as it makes space exploration a painstakingly slow process. Even if we hopped aboard the space shuttle discovery, which can travel 5 miles a second, it would take us about 37,200 years to go one light-year.Travel
