How long would it take to travel 1 Lightyear?
How long would it take to travel 1 Lightyear?
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.
How long would it take to go 2.5 million light years?
(3) Time to travel the distance of 2.5 million light years = (5.88×10^12 miles/LY) x (2.5×10^6 miles) x (1/186,000 miles per second) x (1//60 seconds per minute) x (1/60 minutes per hour) = 21,953,405,017.92115 hours, or, 914,725,209.0800478 days, or, 2,506,096.46323008 years.
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 fast can light travel a million miles?
Light is fast! It can reach the universal speed limit — 186,000 miles per second. (If you could travel as fast as light, the universe would look very different.) Because it moves so quickly, light can seem to appear instantaneously.
How long would it take humans 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.
Do you age if you travel speed light?
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.
Why can we only see 14 billion light-years?
We will never see the light from objects that are currently more than 15 billion light years away, because the universe is still expanding. We are losing 20,000 stars every second to an area that will forever remain beyond our future view.
Is the Milky Way 200000 light-years?
Distance Information The Milky Way is about 1,000,000,000,000,000,000 km (about 100,000 light years or about 30 kpc) across.
How can we see past 13 billion light-years?
We know that light takes time to travel, so that if we observe an object that is 13 billion light years away, then that light has been traveling towards us for 13 billion years. Essentially, we are seeing that object as it appeared 13 billion years ago.
How fast is warp 9 in light years?
Warp factor vs. average speed
| Warp factor | Average speed (×c) | Distance traveled |
|---|---|---|
| 8.5 | 1,251 | 2,500 light years |
| 9 | 834 | approximately 300 billion kilometers (0.032 light years) |
| 9 | 1,718 | 10 light years |
| 9.9 | 21,473 | about 4 billion miles (0.0007 light years) |
Why is warp 10 Impossible?
In-universe, the reason is that warp drive is too slow—you would need generation ships to travel to another galaxy.
How fast is warp speed 10?
In TNG, the warp scale was recalibrated to be asymptotic; warp 10 was infinite speed, at which the traveler occupied all points in the universe simultaneously. Other shows that followed it in the timeline also used this latter scale, notably VOY.
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.
Can we go 20 the speed of light?
Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second). Only massless particles, including photons, which make up light, can travel at that speed. It’s impossible to accelerate any material object up to the speed of light because it would take an infinite amount of energy to do so.
What is 1 light-year away?
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).
Can a person travel 1 light-year?
This duration is a bit of a problem, as it makes space exploration a painstakingly slow process. 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.
How many light-years is the Milky Way?
Our galaxy probably contains 100 to 400 billion stars, and is about 100,000 light-years across.
Can we see 14 billion light-years away?
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.
Is traveling a light-year possible?
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 travel 500 light years?
It would take 500 years to travel 500 light-year distance at the speed of light.
How long would it take to travel 25 000 light years?
The closest galaxy is the recently discovered Canis Major dwarf galaxy, which is “only” 25,000 light-years away. So it would take 25,000 years to get there if you traveled at the speed of light. Actually, that’s the amount of time it would take from the perspective of the outside world.
How long does it take to travel 1000 light years at the speed of light?
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.
