How many years is 93 billion light-years?

How many years is 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 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.

How long would 1 light-year take?

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 many years is 13 billion light-years?

Current observations suggest that the Universe is about 13.7 billion years old. 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.

Is a light-year 9.5 trillion hours?

In a vacuum, light travels at 670,616,629 mph (1,079,252,849 km/h). To find the distance of a light-year, you multiply this speed by the number of hours in a year (8,766). The result: One light-year equals 5,878,625,370,000 miles (9.5 trillion km).

What will Earth look like in 7.5 billion years?

About 7.5 billion years from now, the sun will exhaust its hydrogen fuel and switch to helium. That will cause it to balloon into an enormous red giant. Mars as well as Earth will be fried.

How can a galaxy be 30 billion light-years away?

Because the universe has been expanding the whole time, the researchers estimate the galaxy’s present distance to be roughly 30 billion light years away.

Can we only see 13 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.

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.

Can we travel at 99 the speed of light?

To summarize, according to the immutable laws of physics (specifically, Einstein’s Theory of Special Relativity), there’s no way to reach or exceed the speed of light.

How long would it take to get to 4.24 light-years?

But if it could attain the record-breaking speed of Helios 2’s close approach of the Sun – a constant speed of 240,000 km/hr – it would take 19,000 years (or over 600 generations) to travel 4.243 light-years.

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.

Is the 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).

Is the Milky Way 100000 light-years across?

Our galaxy probably contains 100 to 400 billion stars, and is about 100,000 light-years across.

What is 93 billion light years across the Universe?

As such, one light-year is the equivalent to 9 trillion kilometers / 6 trillion miles, and our Universe is 93 billion light-years in diameter. That’s how big our Universe is, and that’s not even the end of it. The 93 billion years is just the observable Universe, the Universe, which we can currently see.

How long is a 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.

Is the Universe 93 billion light years?

How big is the universe? Well, the observable universe is currently 93 billion light years across. The whole universe is probably infinite.

How far away is 32 billion light years?
