For example, the Milky Way galaxy is some 100,000 light-years across, and our closest galactic neighbor, Andromeda, is some 2.5 million light-years away. In other words, it takes light 2.5 million years just to travel from our galaxy to the one that is right next to us.
How long would it take to travel 1 Lightyear?
Saying we were a space shuttle that travelled five miles per second, given that the speed of light travels at 186,282 miles per second, it would take about 37,200 human years to travel one light year.
How long would it take to travel 6 trillion miles?
A light-year is a measurement of distance and not time (as the name might imply). 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 long would it take to drive to the Andromeda Galaxy?
How long would it take to get to the Andromeda Galaxy? Forget it! 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 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.
Is time Travelling possible?
In Summary: Yes, time travel is indeed a real thing . But it’s not quite what you’ve probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second.
How long would it take to get to Pluto?
Starting from launch on January 19, 2006, and with a gravity assist from Jupiter along the way, NASA’s New Horizons spacecraft took 9 years and 5 months to get to Pluto, 39 AU from the Sun. It traveled at an average speed of 4.1 AU/year. Deep-space missions can take up to 10 years from development to launch.
How long would it take to travel to Mars?
According to NASA, a one-way trip to Mars would take about nine months . If you wanted to make it a round-trip, all in all, it would take about 21 months as you will need to wait about three months on Mars to make sure Earth and Mars are in a suitable location to make the trip back home.
How fast can human travel in space?
Out into space
These G-forces are mostly benign front-to-back Gs, thanks to the smart practice of strapping spacegoers into seats facing their direction of travel. Once at a steady cruising speed of about 16,150mph (26,000kph) in orbit, astronauts no more feel their speed than do passengers on a commercial airplane.
How long would it take to travel 1200 light years?
How long would it take to travel 1200 light years. Kepler-62 is 1,200 light-years from Earth. Even travelling at the speed of light it would take 1,200 years to get there as measured on Earth, so future colonization by earthlings when our planet becomes unlivable would seem unlikely . However, it is not impossible.
How long would it take to travel 4.2 light years?
Proxima Centauri is 4.2 light-years from Earth, a distance that would take about 6,300 years to travel using current technology. Such a trip would take many generations. Indeed, most of the humans involved would never see Earth or its exoplanet counterpart.
Is warp drive faster than the speed of light?
A warp drive is a device that distorts the shape of the space-time continuum. A spacecraft equipped with a warp drive may travel at speeds greater than that of light by many orders of magnitude .
How long would it take to get to the moon at the speed of light?
On average, there is about 238,855 miles (384,400 kilometers) of distance between our planet and its large natural satellite. This means all moonlight we see is 1.255 seconds old, and a round-trip between the Earth and moon at light speed takes about 2.51 seconds .
Where is Voyager 1 now?
NASA’s Voyager 1 spacecraft is currently over 14.1 billion miles from Earth . It’s moving at a speed of approximately 38,000 miles per hour and not long ago passed through our solar system’s boundary with interstellar space.
Is there anything faster than the speed of light?
A reference frame with zero width and with no progression in time is really a reference frame that does not exist. Therefore, this tells us that nothing can ever go faster than the speed of light , for the simple reason that space and time do not actually exist beyond this point.
How long would it take us to get to Jupiter?
The distance between Earth and Jupiter depends on the orbits of each planet but can reach more than 600 million miles. Depending on what the missions do and where they go, it can take around two years to six years to reach Jupiter.
How close can the moon come to Earth?
If the Moon was in an orbit getting closer to Earth, it could reach a distance of roughly 19,000 kilometres (11,800 miles) before the gravity of Earth began pulling its lunar companion apart – this distance is known as the ‘Roche limit’.
How big is the space?
The proper distance—the distance as would be measured at a specific time, including the present—between Earth and the edge of the observable universe is 46 billion light-years (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs) .
Does the past still exist?
In short, space-time would contain the entire history of reality, with each past, present or future event occupying a clearly determined place in it, from the very beginning and for ever. The past would therefore still exist, just as the future already exists, but somewhere other than where we are now present.
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.
Has a time machine been invented?
In fact, a time machine has already been built . Scientists, however, are still working on how to make it as efficient as possible, like in the Back to the Future movies.
How long is 1 year on the Moon?
27 daysHow long would it take to fly to Neptune?
So, Voyager 2 took about twelve years to reach Neptune. As of the time of updating this article in January 2022, Voyager 2 is the only spacecraft to have visited Neptune.
How long would it take to get to moon?
It takes about 3 days for a spacecraft to reach the Moon. During that time a spacecraft travels at least 240,000 miles (386,400 kilometers) which is the distance between Earth and the Moon.
What planet takes 7 years to get to?
| Spacecraft Target Time | Messenger Mercury 6.5 years | Cassini Saturn 7 years | Voyager 1 & 2 Jupiter; Saturn; Uranus; Neptune 13,23 months; 3,4 years; 8.5 years; 12 years | New Horizons Pluto 9.5 years |

Who owns the Moon?
The short answer is that no one owns the Moon . That’s because of a piece of international law. The Outer Space Treaty of 1967, put forward by the United Nations, says that space belongs to no one country.
Will Elon Musk go to Mars?
Elon Musk predicts a crewed mission to Mars in 2029 In 2016, Musk said that a “meaningful number of people” could reach the red planet in 10 years. Now, he seems to predict a crewed Mars landing in 2029.
