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

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

At the speed of light, it would take 13 billion years!

How long does it take to travel 1 light 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.

Could we see a 50 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 far is 46.5 billion light years?

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.

How can we see past 13 billion light years?

It’s because the space between any two points — like us and the object we’re observing — expands with time. The farthest object we’ve ever seen has had its light travel towards us for 13.4 billion years; we’re seeing it as it was just 407 million years after the Big Bang, or 3% of the Universe’s present age.

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

Galaxies may exist at that distance, but their light would be too faint for our telescopes to see. C. Because looking 15 billion light-years away means looking to a time before the universe existed.

How far is 500 million light-years?

Therefore there are 2939312686591800000000 miles in 500 million light years. If we can write in another way the answer will be, There is 2939×1021 a mile in 500 million light years.

Can a human travel a light-year?

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 long would 1000 light-years take?

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.

Is the universe 7 trillion light years?

They found that the universe is at least 250 times larger than the observable universe, or at least 7 trillion light-years across. “That’s big, but actually more tightly constrained that many other models,” according to 2011 MIT Technology Review (opens in new tab) report.

Why can’t we see a 15 billion year old galaxy?

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.

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 can the universe be 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 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.

What’s 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.

What is the oldest thing we can see in the universe?

Astronomers have discovered what may be the oldest and most distant galaxy ever observed. The galaxy, called HD1, dates from a bit more than 300 million years after the Big Bang that marked the origin of the universe some 13.8 billion years ago, researchers said on Thursday.

What is the farthest thing in the universe?

The massive object is a colossal 13.5 billion light-years away. The galaxy candidate HD1 is the farthest object in the universe (Image credit: Harikane et al.) A possible galaxy that exists some 13.5 billion light-years from Earth has broken the record for farthest astronomical object ever seen.

Can we see a galaxy 20 billion light years?

Could we see a galaxy that is 20 billion light-years away? (Assume that we mean a “lookback time” of 20 billion years.) No, because it would be beyond the bounds of our observable universe.

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 1000 light years take?

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.

Why can we only see 14 billion light years?

We will never see the light from objects that are currently more than 15 billion light years away, because the universe is still expanding. We are losing 20,000 stars every second to an area that will forever remain beyond our future view.

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).
