What, walking, swimming? a long time. By definition one light year is how far LIGT travels in one year. That's 5.8 trillion miles, or 5,800,000,000,000!
The only way to travel at the speed of light is to not have any mass.
One light-year is the distance light travels in one year, which is about 5.88 trillion miles. Light doesn't orbit the Earth, but if you're asking how long it takes light to travel around the Earth's circumference once, at the speed of light (about 186,282 miles per second), it would take only about 0.13 seconds.
Yes, but only with the help of mirrors otherwise light would be bknown to travel in wavy lines!
The speed of light doesn't travel at all. It just lays there, typicallyon a printed page in a book.If an object is traveling at the speed of light, however, then it's acompletely different story. Such an object would cover 1 quintillionmiles in only 170,108 years (rounded).
You don't. The only objects that can travel at the speed of light are those that ONLY travel at that speed, like photons or gravitons.
Light travels at a constant velocity, no matter what time it is given to travel. Light would travel at exactly 299,792,458 ms-1 in five minutes, but only in a vacuum.
It only travels in the speed of light
There are only 31,536,000 seconds in a year. So, light can only travel for 31,536,000 in a year.
No such thing would happen. Matter cannot reach the speed of light, only massless things can (and they cannot travel at any other speed than the speed of light).
No. It would take it longer to get from here to there, but only because it would have to travel a longer distance, not because its speed would change.
yes
No. Only light waves can travel through a vacuum.
