# How long would it take to get to the Andromeda galaxy at the speed of light?

Although it may be one of the closest galaxies to our own, since the Andromeda Galaxy is 2.5 million light years distant it would take 2.5 million years to get there if (and it's a huge 'if') we could travel at the speed of light.

## How long would it take a rocket to reach the Andromeda galaxy?

And the Andromeda Galaxy, located a whopping 2.5 million light-years from Earth, could be reachable in only 30 years, assuming you continued to accelerate throughout the entire journey.

## How long will it take Voyager 1 to reach Andromeda?

While Voyager 1 lacks the velocity necessary to escape the Milky Way galaxy, it doesn't actually need to. Because the Milky Way galaxy itself will collide and begin to merge with the Andromeda galaxy within about 4.5 billion years.

## How long would it take to travel our galaxy at the speed of light?

The disk of our home galaxy – the Milky Way – is bigger than we previously thought. 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.

## How far away is Andromeda in light years?

At approximately 2.5 million light-years away, the Andromeda galaxy, or M31, is our Milky Way's largest galactic neighbor. The entire galaxy spans 260,000 light-years across - a distance so large, it took 11 different image segments stitched together to produce this view of the galaxy next door.

## Will humans ever leave the Milky Way?

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.

## Will humans survive Andromeda collision?

Luckily, experts think that Earth will survive, but it won't be entirely unaffected. The collision will unfold right in front of us, changing the night sky to look like nothing any human has seen before.

## How far is Blackhole from Earth?

Though Sagittarius A* is more than 26,000 light years (152 quadrillion miles) away from Earth, it is our closest supermassive black hole. Its formation and physical processes influence our galaxy as galactic matter continually crosses the event horizon, growing the black hole's mass.

## What distance is 1 light year closest to?

A light-year is the distance a beam of light travels in a single Earth year, which equates to approximately 6 trillion miles (9.7 trillion kilometers).

## How fast is Lightspeed?

Light from a stationary source travels at 300,000 km/sec (186,000 miles/sec).

## Will Voyager 2 ever stop?

The two Voyager spacecraft could remain in the range of the Deep Space Network through about 2036, depending on how much power the spacecraft still have to transmit a signal back to Earth.

## Where will Voyager end up?

Not until about 20,000 years from now will the Voyagers pass through the Oort cloud — the shell of comets and icy rubble that orbits the sun at a distance of up to 100,000 astronomical units, or 100,000 times the average Earth-sun distance — finally waving goodbye to its solar system of origin.

## Can a human travel at the speed of light?

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

## How much time would pass if you traveled at the speed of light?

Answer 3: You are correct: it would take ten years. The speed of light has some weird properties: the closer you get to it, the slower time goes for you (but stays the same for everybody else).

## How long would it take to get to Mars at the speed of light?

Traveling At the Speed of Light Towards Mars

If you were to travel at the speed of light, which is around 300,000 kilometers per second or 186,000 miles per second in a vacuum, you would reach Mars at its closest possible approach to Earth in just 3.03 minutes, or 182 seconds.

## How many Earth years is a Lightyear?

Coe et al. For most space objects, we use light-years to describe their distance. A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km).

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

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).

## How many years would it take to travel 4 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.

## Is black hole in Milky Way?

Astronomers believe that supermassive black holes lie at the center of virtually all large galaxies, even our own Milky Way. Astronomers can detect them by watching for their effects on nearby stars and gas.

## Can a wormhole exist?

Einstein's theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date. A negative mass wormhole might be spotted by the way its gravity affects light that passes by.

## Who discovered Earth?

The first person to determine the size of Earth was Eratosthenes of Cyrene, who produced a surprisingly good measurement using a simple scheme that combined geometrical calculations with physical observations.

## How much longer until the Sun dies?

Astronomers estimate that the sun has about 7 billion to 8 billion years left before it sputters out and dies. One way or another, humanity may well be long gone by then.

## How long will our Sun last?

It still has about 5,000,000,000—five billion—years to go. When those five billion years are up, the Sun will become a red giant.

## How long will our galaxy last?

Our Milky Way galaxy is destined to collide with our closest large neighbor, the Andromeda galaxy, in about five billion years.
