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.
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.
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.
It'll take about 1.6 million years to travel 100 light years. If we could harness fusion power for a rocket the most we could improve on this is a factor of 1000. So it would take 1.6 thousand years.
SInce light-year is the distance travelled by the 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 500 light-year distance at the speed of light.
Even traveling at the speed of light, it would take nearly a hundred thousand years!
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.
We can see objects up to 46.1 billion light-years away precisely because of the expanding universe. No matter how much time passes, there will forever be limits on the objects we can observe and the objects that we can potentially reach.
Galaxies may exist at that distance, but their light would be too faint for our telescopes to see. C. Because looking 15 billion light-years away means looking to a time before the universe existed.
Therefore there are 2939312686591800000000 miles in 500 million light years. If we can write in another way the answer will be, There is 2939×1021 a mile in 500 million light years.
Astronomers use another distance unit, the parsec, which represents 3.26 light years or about 20 trillion miles.
Astronomers have discovered the closest known black hole to Earth. The dormant black hole, dubbed Gaia BH1, sits 1,600 light-years away – three times closer than the last black hole to hold the record – in the constellation Ophiuchus. The black hole weighs 10 times the mass of our sun.
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.
A light-year, alternatively spelled light year, is a large unit of length used to express astronomical distances and is equivalent to about 9.46 trillion kilometers (9.46×1012 km), or 5.88 trillion miles (5.88×1012 mi).
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.
Astronomers have discovered what may be the oldest and most distant galaxy ever observed. The galaxy, called HD1, dates from a bit more than 300 million years after the Big Bang that marked the origin of the universe some 13.8 billion years ago, researchers said on Thursday.
The galaxy candidate HD1 is the farthest object in the universe (Image credit: Harikane et al.) A possible galaxy that exists some 13.5 billion light-years from Earth has broken the record for farthest astronomical object ever seen.
The Milky Way is a barred spiral galaxy with an estimated D25 isophotal diameter of 26.8 ± 1.1 kiloparsecs (87,400 ± 3,590 light-years), but only about 1,000 light years thick at the spiral arms (more at the bulge).
Answer and Explanation: Because the universe is estimated to be less than 14 billion years old, conventional wisdom would indicate that we can't see a galaxy 15 billion light-years away because, if anything exists 15 billion light-years away at all, its light hasn't had enough time to reach us.
Up until the discovery of HD1 in 2022, GN-z11 was the oldest and most distant known galaxy yet identified in the observable universe, having a spectroscopic redshift of z = 10.957, which corresponds to a proper distance of approximately 32 billion light-years (9.8 billion parsecs).
Named HD1, the galaxy candidate is some 13.5 billion light-years away and is described today in The Astrophysical Journal . In an accompanying paper published in the Monthly Notices of the Royal Astronomical Society Letters , scientists have begun to speculate exactly what the galaxy is.
So, according to de Rham, the only thing capable of traveling faster than the speed of light is, somewhat paradoxically, light itself, though only when not in the vacuum of space. Of note, regardless of the medium, light will never exceed its maximum speed of 186,282 miles per second.
The nearest star is four light years away. That means that light, traveling at 300,000 kilometers per second would still need FOUR YEARS to reach the nearest star. The fastest spacecraft ever launched by humans would need tens of thousands of years to make that trip.
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.
