## How long would it take to travel 2.7 million light years?

A subspace radio communication can travel 2.7 million light years in **51 years and 10 months** or 52,000 light years per year.

## How long would it take to travel 1 000 light years?

To do so, you will need a speed of almost the speed of light, so in the reference frame of Earth, you will have spent just a tad more that 1000 yr to travel 1000 ly. i.e. **1000 years, 4 hours, and 23 minutes** in Earth’s reference frame.

## How long would it take to travel 4 2 light years?

Last year, astronomers raised the possibility that our nearest neighbor, Proxima Centauri, has several potentially habitable exoplanets that could fit the bill. Proxima Centauri is 4.2 light-years from Earth, a distance that would take **about 6,300 years** to travel using current technology.

## How far away is Voyager 1 in light years?

The spacecraft’s next big encounter will take place in 40,000 years, when Voyager 1 comes within **1.7 light-years** of the star AC +79 3888. (The star itself is roughly 17.5 light-years from Earth.)

## How long would it take to travel to Pluto?

The $720 million New Horizons mission launched in January 2006, speeding away from Earth at a record-breaking 36,400 mph (58,580 km/h). Even at that blistering pace, it still took the probe **9.5 years** to reach Pluto, which was about 3 billion miles (5 billion km) from Earth on the day of the flyby.

## How fast is warp speed?

In the sci-fi universe of “Star Trek,” spaceships with warp drives can zoom past the normally impenetrable limit of light speed, or **about 186,282 miles per second** (299,792 kilometers per second) in a vacuum.

## How many Earth years is a Lightyear?

A light-year is the distance light travels in **one Earth year**. One light-year is about 6 trillion miles (9 trillion km). One light year is equal to the distance that light travels in one year (it is about ten trillion kilometers, or six trillion miles). One light years is equal to approx 6.5×10^5 earht s years.

## How long did it take Voyager to get home?

The Voyager embarks on its journey home, which is calculated to take **approximately 75 years**, while trying to stay alive and documenting the undiscovered places they find themselves stranded in.

## How long would it take to travel to Mars?

The cruise phase begins after the spacecraft separates from the rocket, soon after launch. The spacecraft departs Earth at a speed of about 24,600 mph (about 39,600 kph). The trip to Mars will take **about seven months** and about 300 million miles (480 million kilometers).

## Can humans travel at the speed of light?

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**. … So, light-speed travel and faster-than-light travel are physical impossibilities, especially for anything with mass, such as spacecraft and humans.

## How long would it take to travel across the universe at the speed of light?

A new study shows it would take **200,000 years** for a spaceship traveling at the speed of light to go across the entire galaxy.
