What is 9.5 trillion km away from Earth?

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).

How long does it take to travel 9.5 trillion km?

How far is that? Multiply the number of seconds in one year by the number of miles or kilometers that light travels in one second, and there you have it: one light-year. It's about 5.9 trillion miles (9.5 trillion km).

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 is the distance light travels in a year about 9.5 trillion kilometers?

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 9.46 trillion kilometers?

Light is the fastest thing in our Universe traveling through interstellar space at 186,000 miles/second (300,000 km/sec). In one year, light can travel 5.88 trillion miles (9.46 trillion km).

Is Time Travel Possible In Our Universe?

How many light years is Voyager 1?

Traveling at speeds of over 35,000 miles per hour, it will take the Voyagers nearly 40,000 years, and they will have traveled a distance of about two light years to reach this rather indistinct boundary.

How fast is the actual speed of light?

So what does this sentence really mean? Surprisingly, the answer has nothing to do with the actual speed of light, which is 300,000 kilometers per second (186,000 miles per second) through the "vacuum" of empty space.

How long will it take to travel 1,000 light-year?

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 can we see 14 billion light years away?

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.

How long would it take to go 46 billion light years?

Save this answer. Show activity on this post. We don't see stars and galaxies at a proper distance of 46 Gly, because this distance corresponds to a light travel time of 13.7 billion years, or very shortly after the big bang.

How far does space go?

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 many light years can we see?

The universe is only 13.8 billion years old, but we can see back 46.1 billion light-years. Here's how the expanding universe does it.

Is there anything faster than the speed of light?

Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second). Only massless particles, including photons, which make up light, can travel at that speed. It's impossible to accelerate any material object up to the speed of light because it would take an infinite amount of energy to do so.

How much is 9.5 trillion km?

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.

How far from Earth can we go?

And the limitations of Einstein's relativity, preventing us from teleporting or traveling faster than light, might not ever be overcome. Even without invoking any new physics, we'd be able to travel surprisingly far in the Universe, reaching any object presently less than 18 billion light-years away.

Can we travel a 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.

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 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.

What is bigger than universe?

No, the universe contains all solar systems, and galaxies. Our Sun is just one star among the hundreds of billions of stars in our Milky Way Galaxy, and the universe is made up of all the galaxies – billions of them.

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.

Is it possible to travel 500 light-years?

The light travels at the speed of 1 light year. Therefore, if we assume light to be travelling, then it will travel 500 light years in 500 years. The light travels at a speed of c=3×108ms−1. Therefore, the distance travelled in one day will be 2.6×1013m.

What is the closest black hole to Earth?

The closest black hole to Earth is a stellar mass black hole just 1,600 lightyears away called Gaia BH1. The black hole has set a new record for the closest known black hole to Earth. Its presence was revealed after ESA's Gaia space telescope observed the unusual motion of its stellar companion, a Sun-like star.

How fast is the speed of dark?

Darkness travels at the speed of light. More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light. Any time you block out most of the light – for instance, by cupping your hands together – you get darkness.

What is the fastest thing in the universe?

So light is the fastest thing. Nothing can go faster than that. It's kind of like the speed limit of the universe.

How fast is 100% speed of light?

The speed of light traveling through a vacuum is exactly 299,792,458 meters (983,571,056 feet) per second. That's about 186,282 miles per second — a universal constant known in equations as "c," or light speed.
