How long would it take to travel 1 billion light years?

How long would it take to travel 1 billion light years?

It looks like this: If a person travels 1 billion light years at 0.999999 light speed, this will occur almost instantly for him. But for other observers, this will take him 1 billion years.

How far is 1 light years away in miles?

A light-year is the distance light travels in one Earth year. One light-year is about 6 trillion miles (9 trillion km). That is a 6 with 12 zeros behind it!

How many billions of miles is a 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.

How long is 1 light-year in Earth years?

Since light travels at about 186,300 miles per second, with 86,400 seconds per day and about 365 days per year, that works out at about: 186300×86400×365≈5,875,000,000,000 miles.

Why is space infinite?

There’s a limit to how much of the universe we can see. The observable universe is finite in that it hasn’t existed forever. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).

How big is the known universe?

Size: 94 Billion Light Years. The most distant objects in the Universe are 47 billion light years away, making the size of the observable Universe 94 billion light years across. How can the observable universe be larger than the time it takes light to travel over the age of the Universe?

How long would it take you 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 1 light-year in the US?

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.

How long would it take to go 13 billion light-years?

It is traveling at 17 KPS (Kilometers per second). That translates to 38,000 MPH. Providing that speed remains constant it would take about 2.34 X 10^14 years to cover the distance.

How long would it take you to travel 4 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.

How long would it take to get to the sun?

At this speed, how many days would it take to travel to the sun from Earth, located at a distance of 149 million kilometers? Answer: Time = Distance/speed so Time = 149,000,000 km/ 28,000 = 5321 hours or 222 days.

Is a light-year 365 days?

A light year is the distance light travels in one year (365 days). It often gets misused as a unit of time, likely because ‘year’ is right there in the name. It will always take light 1 year to travel a distance of 1 light year.

How many light-years can we go?

The light that travels the longest gets stretched by the greatest amount, and the object that emitted that light is now at a greater distance because the universe is expanding. We can see objects up to 46.1 billion light-years away precisely because of the expanding universe.

Are light-years quick?

So we speak of space objects in terms of light-years, the distance light travels in a year. Light is the fastest-moving stuff in our universe. It travels at 186,000 miles per second (300,000 km/sec). And thus a light-year is 5.88 trillion miles (9.46 trillion kilometers).

How long would it take to travel 1,000 light years?

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.

How long would it take to travel 14 billion miles at the speed of light?

NASA’s long-lived spacecraft reaches another milestone NASA’s extraordinarily long-lived Voyager 1 probe this week passed 14 billion miles from Earth. It takes light nearly 21 hours to reach the spacecraft, making commanding the thing increasingly tricky.

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.

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.
