How long does it take to get to Andromeda at the speed of light?

How long does it take to get to Andromeda 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 Voyager 1 to reach Andromeda?

“… and even if we ignored that – it would need 3.3 billion years for the journey at the current distance.”

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

“If it could travel at the speed of light, an impossibility due to Special Relativity, it would still take over 26,000 years to arrive!”

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

“If, then, we ever devised a way to travel at the speed of light, then the simplest answer to today’s question is that it would take 46 billion years to move across the entire cosmos.”

How many years is 500 light years?

“It would take 500 years to travel 500 light-year distance at the speed of light.”

How many years is 1 light-year?

“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.”

Will Voyager 1 ever stop moving?

“How long can Voyager 1 and 2 continue to function? Voyager 1 is expected to keep its current suite of science instruments on through 2021. Voyager 2 is expected to keep its current suite of science instruments on through 2020. The radioisotope thermoelectric generator on each spacecraft puts out 4 watts less each year.”

Will Voyager 1 escape the Milky Way?

“In August 2012, Voyager 1 became the first spacecraft to cross into interstellar space. However, if we define our solar system as the Sun and everything that primarily orbits the Sun, Voyager 1 will remain within the confines of the solar system until it emerges from the Oort cloud in another 14,000 to 28,000 years.”

How far will Voyager 1 be in 2025?

“The Voyagers have enough electrical power and thruster fuel to keep its current suite of science instruments on until at least 2025. By that time, Voyager 1 will be about 13.8 billion miles (22.1 billion kilometers) from the Sun and Voyager 2 will be 11.4 billion miles (18.4 billion kilometers) away.”

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

“Other Galaxies”

“

Object	Time for the Light to Reach Us
The Moon	1 1/3 sec
The Sun	8 minutes
Jupiter	35 to 52 minutes
Pluto	5 1/2 hours (on average)

“

Will man ever travel at the speed of light?

“Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. According to Albert Einstein’s theory of special relativity, summarized by the famous equation E=mc2, the speed of light (c) is something like a cosmic speed limit that cannot be surpassed.”

How long would it take to get to Proxima Centauri at the speed of light?

“Travel Time If Voyager were to travel to Proxima Centauri, at this rate, it would take over 73,000 years to arrive. If we could travel at the speed of light, an impossibility due to Special Relativity, it would still take 4.22 years to arrive!”

Do you age at the speed of light?

“Five years on a ship traveling at 99 percent the speed of light (2.5 years out and 2.5 years back) corresponds to roughly 36 years on Earth. When the spaceship returned to Earth, the people onboard would come back 31 years in their future–but they would be only five years older than when they left.”

How fast is the speed of dark?

“Darkness travels at the speed of light. More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light. Any time you block out most of the light – for instance, by cupping your hands together – you get darkness.”

Is anything faster than the speed of light?

“Nothing in the universe can go faster than the speed of light. As it happens, it was an illusion, a study published in the journal Nature explained earlier this month.”

How long would 1000 light-years take?

“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.”

What planet is 400 light-years away?

“The grainy image of a “super-Jupiter” is a sign of what’s to come as the telescope’s exoplanet observations ramp up. Behold the bright blob of planet HIP 65426 b, located nearly 400 light-years away.”

How many light-years away have we gone?

“Looking up at the sky, we see light that’s at most 13.8 billion years old and coming from stuff that’s now 46 billion light years away. Anything farther is beyond the horizon, but each second, we see new, even older light coming from slightly farther away, three light seconds farther, to be precise.”

How long would it take to get to Proxima Centauri at the speed of light?

“Travel Time If Voyager were to travel to Proxima Centauri, at this rate, it would take over 73,000 years to arrive. If we could travel at the speed of light, an impossibility due to Special Relativity, it would still take 4.22 years to arrive!”

How long would it take to get to the Andromeda galaxy at warp speed?

“To reach M31, the Andromeda galaxy, in a human lifetime would require a velocity of 0.99999 c. Behind the relativistic spacecraft on Earth, millions of years would have passed, but the same crew that departed would reach their destination.”

How long would it take to get to Alpha Centauri at the speed of sound?

“Alpha Centauri is about 25,000,000,000,000 miles away. Sound at sea level travels about 760 miles per hour (under standard conditions). So it would take sound about 3,750,000 years to get there if standard air extended all the way to the star.”

How long is 5 years at the speed of light?

“That depends on how fast you’re traveling. Thanks to Einstein, we know that the faster you go, the slower time passes–so a very fast spaceship is a time machine to the future. Five years on a ship traveling at 99 percent the speed of light (2.5 years out and 2.5 years back) corresponds to roughly 36 years on Earth.”
