It takes light 40 years to travel a distance of 40 light years.
As far as light can travel
27,000 light-years is a distance of 158,720,000,000,000,000 miles. This is the distance light will travel in 27,000 years.
222 billion miles = 0.0377647371 light years.
The formula to calculate travel time at the speed of light is distance divided by the speed of light. The nearest star to Earth is Proxima Centauri, which is about 4.24 light-years away. Therefore, the travel time to Proxima Centauri at the speed of light would be 4.24 years.
It would take approximately 65 years to travel at the speed of light from Earth to Aldebaran, which is about 65 light-years away. However, currently, we do not have the technology to travel at the speed of light.
Light travels at a speed of 186,282 miles per second. To convert light-years to hours, divide the distance in light-years by the speed of light. Therefore, 310 light-years would take approximately 1,874,579 hours to travel.
Well, it takes 2,700 years for light to travel that far. Anything travelling at half light-speed would take 5,400 years. At 1/4 light-speed, it would take 10,800 years.
from the book
In 20 years, light will travel 1.17569996 × 1014 miles in a vacuum.
14 Billion years
Yes. It is 13.7 billion light-years in radius in light travel distance according to Ned Wright's Cosmology calculator.
