How many light-seconds away is the Sun?

It takes 499.0 seconds for light to travel from the Sun to the Earth, a distance called 1 Astronomical Unit. 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. Answer and Explanation: The Moon is about 384,400 km from the Earth, or just about one light-second (the distance that light travels per second). The Moon is about 4.063×10−11 4.063 × 10 − 11 light-years from the Earth. Our galaxy probably contains 100 to 400 billion stars, and is about 100,000 light-years across. 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.

How long is 1 second in light speed?

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. What about light hours? How fast can light travel in an hour? To calculate how fast light can travel in an hour multiply the distance light can travel in a minute by 60 since there is 60 minutes in an hour. So light travels 1,080,000,000 kilometers or 669,600,000 miles in one hour! A light day is an astronomical unit of length. It is defined as the distance light travels in an absolute vacuum in one day (of 86,400 seconds) or 25,902,068,371,200 meters (~26 Tm). Based on our current understanding of physics and the limits of the natural world, the answer, sadly, is no. According to Albert Einstein’s theory of special relativity, summarized by the famous equation E=mc2, the speed of light (c) is something like a cosmic speed limit that cannot be surpassed. At its average distance of 142 million miles, light takes 12 minutes and 42 seconds to reach Earth from Mars.

How far is the black hole?

Because the black hole is about 27,000 light-years away from Earth, it appears to us to have about the same size in the sky as a donut on the Moon. A black hole is a place where space is falling faster than light. One hour for a black hole observer would equate to 100,000,000 years for a person on Earth. Therefore one minute in a black hole would be roughly 1,700,000 years. There are likely to be many more planetary systems out there waiting to be discovered! Our Sun is just one of about 200 billion stars in our galaxy. As black holes evaporate, they get smaller and smaller and their event horizons get uncomfortably close to the central singularities. In the final moments of black holes’ lives, the gravity becomes too strong, and the black holes become too small, for us to properly describe them with our current knowledge.

What 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. 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. That’s because all massless particles are able to travel at this speed, and since light is massless, it can travel at that speed. 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. And there’s an ultimate cosmic speed limit that applies to every object: nothing can ever exceed the speed of light, and nothing with mass can ever reach that vaunted speed.
