How long would it take to travel 93 billion light years?

How long would it take to travel 93 billion light years?

The universe is technically infinite but 93 billion light years is the diameter of the observable universe. Assuming you are at one side of the observable universe and you want to travel to the end at light speed…well, duh, the time taken will clearly be 93 billion years!

How far away is 1 light-year in km?

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.

What is the meaning of 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! Q.

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.

How 1 hour in space is 7 years on Earth?

The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.

What does 1 light-year look like?

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!

What is 1 light-year in human years?

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.

How big is the universe in KM?

Explanation: The diameter of the Observable Universe is about 46.5 billion light years or 4.40 x 1023 km.

How old is the Milky Way?

Astronomers believe that our own Milky Way galaxy is approximately 13.6 billion years old.

How far is the known universe?

The comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs (46.5 billion light-years or 4.40×1026 m) in any direction. The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8×1026 m).

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.

What is beyond the Universe?

The trite answer is that both space and time were created at the big bang about 14 billion years ago, so there is nothing beyond the universe. However, much of the universe exists beyond the observable universe, which is maybe about 90 billion light years across.

How fast speed of light is?

Light from a stationary source travels at 300,000 km/sec (186,000 miles/sec).

How far can we see in space?

So the furthest out we can see is about 46.5 billion light years away, which is crazy, but it also means you can look back into the past and try to figure out how the universe formed, which again, is what cosmologists do.

How far is 4000 light years?

Roughly 4,000 light-years (about 24 quadrillion miles) away from Earth in a particularly happening region of the universe full of star clusters, nebulae, and a star-forming molecular cloud, there is a constellation known as Ara.

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

Travelling at the speed of light, it would take 1 trillion years.

How long would it take to travel 100 trillion light years?

Some galaxies will have fallen over the cosmic horizon, where no amount of time would ever let you reach them. If you wanted to travel 100 trillion light years away, you could make the journey in 62 years.

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 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.
