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

That's equivalent to traveling around the Earth more than 6 trillion times! Even if you had a spaceship capable of reaching the speed of light (which is impossible), it would still take 40 years for you to get there.

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

Travel Time

At the rate of 17.3 km/sec (the rate Voyager is traveling away from the Sun), it would take around 225,000,000,000,000 years to reach this distance.

How long would it take to travel 1 light-years away?

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.

Can we see things 14 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 a human to travel 1000 light-years?

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.

How Long Does It Take To Travel 1 Light Year | Science Of Space

Can we go 1% the speed of light?

So will it ever be possible for us to travel at light speed? Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no.

How far away is 1 lightyear in miles?

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's the farthest we've seen in space?

28 Billion Light-Years Away: The Most Distant Star Ever Discovered. On Wednesday, NASA announced the Hubble telescope broke a new record– detecting the most distant star ever seen.

What is beyond our 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 do they know the universe is 13.7 billion years old?

We do not know the exact age of the universe, but we believe that it is around 13 billion years - give or take a few billion. Astronomers estimate the age of the universe in two ways: (a) by looking for the oldest stars; and (b) by measuring the rate of expansion of the universe and extrapolating back to the Big Bang.

How fast is a light-year in mph?

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.

Is there anything faster than the speed of light?

In special relativity, the speed of light is the ultimate speed limit to the universe. Nothing can travel faster than it.

How much time would pass on Earth if you traveled at the speed of light?

At 99.99999 percent of the speed of light, for a year, more than 2000 years would pass on Earth. The point is, the closer you get to the speed of light, the more time dilation is experienced. Achieving those speeds, however, is incredibly unlikely and probably impossible.

Is space infinite?

Because space isn't curved they will never meet or drift away from each other. A flat universe could be infinite: imagine a 2D piece of paper that stretches out forever. But it could also be finite: imagine taking a piece of paper, making a cylinder and joining the ends to make a torus (doughnut) shape.

What's the farthest thing from Earth?

Astronomers have measured the distance to the farthest cosmic object known to humankind: a galaxy that lies 13.1 billion light-years away.

How far back in time can we see?

We can see light from 13.8 billion years ago, although it is not star light – there were no stars then. The furthest light we can see is the cosmic microwave background (CMB), which is the light left over from the Big Bang, forming at just 380,000 years after our cosmic birth.

Is there an unobservable universe?

It will reveal slightly more than twice the volume of the Universe we can observe today. The unobservable Universe, on the other hand, 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 many dimensions exist?

The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there's the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.

What is the ultimate answer to the universe?

42 is the answer to the “ultimate question of life, the universe, and everything,” a joke in Douglas Adams's 1979 novel, The Hitchhiker's Guide to the Galaxy.

What is the oldest thing in the universe?

HD 140283 had a higher than predicted oxygen-to-iron ratio and, since oxygen was not abundant in the universe for a few million years, it pointed again to a lower age for the star. As a result of all of this work, Bond and his collaborators estimated HD 140283's age to be 14.46 billion years.

How many galaxies are there?

One such estimate says that there are between 100 and 200 billion galaxies in the observable universe. Other astronomers have tried to estimate the number of 'missed' galaxies in previous studies and come up with a total number of 2 trillion galaxies in the universe.

What is the fastest possible space travel?

But Einstein showed that the universe does, in fact, have a speed limit: the speed of light in a vacuum (that is, empty space). Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second).

Why can't we travel faster than light?

The real reason you cannot travel through space faster than light is because you are always traveling through spacetime at the speed of light.

What's the closest star to Earth?

Distance Information

Proxima Centauri, the closest star to our own, is still 40,208,000,000,000 km away. (Or about 268,770 AU.)

What happens at 1% the speed of light?

While 1% of anything doesn't sound like much, with light, that's still really fast – close to 7 million miles per hour! At 1% the speed of light, it would take a little over a second to get from Los Angeles to New York. This is more than 10,000 times faster than a commercial jet.
