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 is the universe 93 billion light years?

We are able to see the farthest galaxy almost 13.8 billion light years away. 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.

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.

Is light-year billions of miles?

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).

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.

How many km is the universe?

The radius of the observable universe is therefore estimated to be about 46.5 billion light-years and its diameter about 28.5 gigaparsecs (93 billion light-years, or 8.8×1026 metres or 2.89×1027 feet), which equals 880 yottametres.

How big is our universe in miles?

When we look in any direction, the furthest visible regions of the Universe are estimated to be around 46 billion light years away. That’s a diameter of 540 sextillion (or 54 followed by 22 zeros) miles.

What is 1 light-year in human years?

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 far is the edge of the universe?

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.

Is 1 light-year the largest distance?

The result: One light-year equals 5,878,625,370,000 miles (9.5 trillion km). At first glance, this may seem like an extreme distance, but the enormous scale of the universe dwarfs this length. One estimate puts the diameter of the known universe at 28 billion light-years in diameter.

How big is the Milky Way?

How long would it take us 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. Indeed, most of the humans involved would never see Earth or its exoplanet counterpart.

How fast speed of light is?

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

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.

Does light ever stop traveling?

No, in fact light only stops when it is absorbed by an electron in an atom of an object. Light in a perfect vacuum travels on at its full speed until it hits something.

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 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 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.
