In one nanosecond (ns), light will travel 30.0 cm, about 1 ft.
The speed of light (in a vacuum*) =
186,000 miles per second, or
0.000186 miles per nanosecond, around 1 foot/ns.
*note: Light travels slower moving through matter.
Assuming you are referring to our Galaxy - The Milky Way. Light will take about 100,000 years to get from one side to the other.
Depends on your speed. A light year is the distance light travels in a year. If you traveled slower it would take longer.Depends on the speed you are going.At the speed of light one year.See related question for details of a light yearJust like any other distance, it depends on the speed of travel.-- At the speed of light, radio, x-rays, etc., it takes 1 year.-- At 1 million miles per hour, it takes about 671 years.-- At 60 miles per hour, it takes about 11.2 million years.A light year is the distance that light will travel in one year in a vacuum. The speed of light is 186,000 miles per second. So, light will travel about 5.8 trillion miles in one year. Now, to answer the question. The answer depends on how fast you are traveling. If you were in a space ship travelling 99.9999% the speed of light, it would take you about a year to travel a light year. Now, there is currently no human-made space craft, that we know of, that can travel that fast. The space shuttle travels at about 17,500 miles per hour. In order for the space shuttle to travel one light year, it would take about 38,262 years.
That cannot be answered unless the velocity is known.
No one really knows, because no one has ever been to Betelgeuse. It would take much more time than getting to Pluto.
There is currently no technology that would enable human astronauts, from NASA or from any other organization, to travel one light year. There are some theoretical proposals for ideas that might work, but nothing even on the horizon for now. we can travel in space ROUGHLY 30,000 mph...at that rate it would take us ROUGHLY 22,366 years to travel 1 light year
It takes light exactly one hour to travel in 1 hour.
Light travels a distance of one light year in one year.
That should be one-thousandth of a second.
Approximately two months.
A lightyear is the distance that light can travel in one year.
One second.
Assuming you are referring to our Galaxy - The Milky Way. Light will take about 100,000 years to get from one side to the other.
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.
It take the light to travel for 2 million years Actually about 100 years, maybe less.
Between 100,000 and 180000 years.
Between 100,000 and 180000 years.
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!
