What is 93 billion light years?

What is 93 billion light years?

The scientists have estimated their current location, due to the expansion of the universe as 46.5 billion light years away, hence the diameter of the visible universe is 93 billion light years. This means that the farthest galaxies moved 30 billion light years away in 13.8 billion years.

How many zeros in 93 billion light years?

It is estimated that the Observable Universe is about 93 billion light years in diameter, i.e. in kilometres, this number is 88 with 22 zeroes after it!

How long is a light-year in years?

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 travel 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.

Is a light-year 1 Earth year?

For most space objects, we use light-years to describe their distance. 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 big is the unknown universe?

This means the unobservable Universe, assuming there’s no topological weirdness, must be at least 23 trillion light years in diameter, and contain a volume of space that’s over 15 million times as large as the volume we can observe.

How big is the total universe?

While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day.

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.

Why is universe 92 billion light years?

While the estimate of 92 billion light-years comes from the idea of a constant rate of inflation, many scientists think that the rate is slowing down. If the universe expanded at the speed of light during inflation, it should be 10^23, or 100 sextillion.

Can we 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.

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 far is 1 light-year from Earth?

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).

Will Voyager 1 ever stop?

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.

Can we see 100 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 many universes are there?

In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16.

How long would it take to travel a billion light-years?

If your spacecraft could travel at 1% of the speed of light, or about 3,000 km/second, it would take you: 300,000 / 3000 x 1 billion light years ==100 billion years to travel a distance of 1 billion light years.

Why is universe 92 billion light-years?

While the estimate of 92 billion light-years comes from the idea of a constant rate of inflation, many scientists think that the rate is slowing down. If the universe expanded at the speed of light during inflation, it should be 10^23, or 100 sextillion.

Can we see 100 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.

Why can’t we see 15 billion light-years away?

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.
