How many billions of miles is a light-year?

How many billions of miles is a light-year?

Coe et al. 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).

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

If your spacecraft could travel at 1% of the speed of light, or about 3,000 km/second, it would take you: 300,000 / 3000 x 1 billion light years ==100 billion years to travel a distance of 1 billion light years.

How many miles is a billion?

The length of 1,000,000,000 (one billion) one dollar bills laid end-to-end measures 96,900 miles.

How long does it take for light to travel 1 billion km?

Note- One billion kilometer (1 billion km) is equal to 109 km 10 9 km , one kilometer is equal to one thousand meter (1 km = 1000 m) and the speed of light is V=3×108 m/s V = 3 × 10 8 m/s . Thus, the time taken by the light to travel a given distance is 56 minutes.

How far is 1 light-year?

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 far is 1 light-year from Earth?

A light-year is the distance a beam of light travels in a single Earth year, which equates to approximately 6 trillion miles (9.7 trillion kilometers).

Can a human travel 1 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 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.

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

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 far is 10 billion miles?

If you wanted to ditch the car and walk those 10 billion miles, it would take you 361,492 years. Be sure to wear some comfortable shoes. Those miles can add up.

How many miles is the universe?

The edge of the observable universe is about 270,000,000,000,000,000,000,000 miles away. If you drive at a steady 65 miles per hour, it will take you 480,000,000,000,000,000 — that’s 4.8 × 10¹⁷ — years to get there, or 35 million times the current age of the universe.

Has a car ever done 1 million miles?

Louis County, Missouri, recently drove his Volvo 740 GLE past the million-mile mark. “The good thing about this car is, it can’t get me in any trouble because it goes about 75 miles per hour, tops,” said O’Shea. Thirty years, two engines and two transmissions later, the Swedish sedan still runs despite its rust.

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.

Is faster than light travel possible?

Within conventional physics, in accordance with Albert Einstein’s theories of relativity, there’s no real way to reach or exceed the speed of light, which is something we’d need for any journey measured in light-years.

Is anything faster than the speed of light?

So, according to de Rham, the only thing capable of traveling faster than the speed of light is, somewhat paradoxically, light itself, though only when not in the vacuum of space. Of note, regardless of the medium, light will never exceed its maximum speed of 186,282 miles per second.

How long is the Milky Way?

The Milky Way is about 1,000,000,000,000,000,000 km (about 100,000 light years or about 30 kpc) across. The Sun does not lie near the center of our Galaxy.

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.

How big is the Milky Way?

Is 140000000 miles away from the sun?

The distance from Earth to the Sun is 93 million miles (149 million kilometers), but the distance to the farthest planet Neptune is nearly 3 billion miles (4.5 billion kilometers).

What is 100000 light-years away?

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. The Sun does not lie near the center of our Galaxy. It lies about 8 kpc from the center on what is known as the Orion Arm of the Milky Way.

How long does it take light to travel 14 billion miles?

NASA’s long-lived spacecraft reaches another milestone NASA’s extraordinarily long-lived Voyager 1 probe this week passed 14 billion miles from Earth. It takes light nearly 21 hours to reach the spacecraft, making commanding the thing increasingly tricky.

How many human years is a light-year?
