Traveling 40 light years would take 40 years at the speed of light.
If you were to travel at the speed of light for a year, no time would pass for you, but approximately one year would pass on Earth.
The light takes approximately 8 minutes and 20 seconds to travel through layer 3.
Light energy consists of electromagnetic waves that travel at the speed of light, while sound energy consists of mechanical waves that travel at a much slower speed. Light energy does not require a medium to travel through, whereas sound energy does. Light energy can travel through a vacuum, whereas sound energy cannot.
Yes, thoughts travel much faster than light as they are generated by electrical impulses in the brain that can travel up to 268 miles per hour. In contrast, the speed of light is about 186,282 miles per second in a vacuum.
Similarities: Both light and sound waves are forms of energy that travel in waves. They can both be reflected, refracted, and diffracted. Differences: Light waves can travel through a vacuum, while sound waves require a medium to travel through. Light waves are electromagnetic waves, while sound waves are mechanical waves that require a medium to propagate. Light waves travel much faster than sound waves.
2 billion years.
well the crab nebula is about 6,500 light years away so it would take 6,500 years to get there at the speed of light but we do not have any space craft that travel at that speed so it would take over a billion if not trillion years to get there!
Traveling 20 million light years at the speed of light would take 20 million years. Since we do not currently have technology that can travel at the speed of light, it would take much longer using current spacecraft technology.
Traveling 600 million light years would take an impossibly long time, considering the current limits of our technology. Even traveling at the speed of light (which is not feasible for matter with mass), it would still take 600 million years to cover that distance. The vastness of space makes interstellar travel on such a scale unrealistic with our current knowledge and technology.
It would take approximately 100,000 years to travel from one end of the Milky Way to the other at the speed of light, which is about 186,282 miles per second. However, with current technology, it would take much longer to traverse the Milky Way.
It wouldn't be possible using our current technology; with our current technology, it takes 10 years to get outside our own solar system. With technology that we could reasonably develop within the next 50 years, it should be possible to create a spacecraft that could travel 490 light years in ONLY 5,000 years or so. We know the basic principles for an Orion Nuclear Pulse Rocket, but it would be phenomenally expensive and impractical to build one to go 490 light years. The first such spacecraft will travel to much nearer stars.
well it depends on what you are measuring your 'much' in. First thing is, a light year is a distance not a time. It is defined as the distance light would travel in the time of one human year. Now to define this: light travels at ~300000000ms-1 and there are 31536000s in one year, so light will travel: 300000000*31536000 = 9.5x1015 metres in one year (that is 95 followed by 14 zeros! so a long distance) so in 9.7 light years light will travel 9.2x1016 metres. Which is a very very long distance.
Travelling at the speed of light, It would take about 2.5 million years. Travelling at conventional rocket speeds, it would take billions of years.
It will contiunue to travel until it encounters something that absorbs it, even if that doesn't happen for a billion years. There is no limit to the distance.
It takes about 3 days to travel to the moon using current spacecraft technology.
It would take a car traveling at 60 mph (96.5 km/h) approximately 19 million years to travel one light year, assuming it could travel at a constant speed without refueling or stopping. However, it's physically impossible for a car to travel at the speed of light, so it would actually take much longer.
No one really knows, because no one has ever been to Betelgeuse. It would take much more time than getting to Pluto.
