How long is 1 light-year in Earth years?
How long is 1 light-year in Earth years?
Since light travels at about 186,300 miles per second, with 86,400 seconds per day and about 365 days per year, that works out at about: 186300×86400×365≈5,875,000,000,000 miles.
How far is 100 000 light-years?
Distance Information The Milky Way is about 1,000,000,000,000,000,000 km (about 100,000 light years or about 30 kpc) across. The Sun does not lie near the center of our Galaxy.
How long would it take to travel 100 light-years from Earth?
It’ll take about 1.6 million years to travel 100 light years.
How long would it take to travel 1000 light-years?
Answer: 4 Billion Years. A custom-built interstellar space ship would travel faster than my car but slower than the speed of light.
Is a light-year 4 years?
Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.
Do you age in light-years?
Re: How would you age at the speed of light The simple answer is, anything moving through space at c, equal to the speed of light in a vacuum, experiences zero time flow. If you were to travel at the speed of light, you would experience no time.
How long would it take to go 1 light-year away?
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.
How many light-years exist?
The universe is only 13.8 billion years old, but we can see back 46.1 billion light-years. Here’s how the expanding universe does it. Artist’s logarithmic scale conception of the observable universe.
How long would it take to travel 100 trillion light-years?
Some galaxies will have fallen over the cosmic horizon, where no amount of time would ever let you reach them. If you wanted to travel 100 trillion light years away, you could make the journey in 62 years.
Can humans travel a light-year?
So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no.
How long would it take to travel 25 000 light-years?
The closest galaxy is the recently discovered Canis Major dwarf galaxy, which is “only” 25,000 light-years away. So it would take 25,000 years to get there if you traveled at the speed of light. Actually, that’s the amount of time it would take from the perspective of the outside world.
Does it take 4 years for light to travel?
Light travelling at a speed of 300000 km per sec takes just over 8 minutes from the Sun and just over 4 years from Proxima Centauri.
Can we go to another galaxy?
The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.
How far back in time can we see?
We can see light from 13.8 billion years ago, although it is not star light – there were no stars then. The furthest light we can see is the cosmic microwave background (CMB), which is the light left over from the Big Bang, forming at just 380,000 years after our cosmic birth.
How fast speed of light is?
Light from a stationary source travels at 300,000 km/sec (186,000 miles/sec).
How long would it take to travel 500 light-years?
Since a light-year is the distance travelled by light in one year while travelling with the speed of light i.e. 3×108m/s 3 × 10 8 m / s , it would take 500 years to travel the distance of 500 light-years at the speed of light.
How far does space go?
So the furthest out we can see is about 46.5 billion light years away, which is crazy, but it also means you can look back into the past and try to figure out how the universe formed, which again, is what cosmologists do.
How long is a light-year a second?

What is within 1000 light-years away from Earth?
European astronomers have found the closest black hole to Earth yet – so near that two stars orbiting it can be seen by the naked eye. Of course, close is relative on the galactic scale. This black hole is about 1,000 light-years away and each light-year is 9.46 trillion kilometres.
How many years would it take to travel 4 light-years?
How long would it take to travel 4 light years? At half the speed of light, 6 years 11 months and 12 days. At 99% of light speed, 6 months and 24 days.
