- Patricia Jones, M.A. Do not confuse the silent treatment with something known as “the cooling off period”. The cooling off period is where one person is so angry or disgusted by the other person that they just cannot deal with the situation in that state, and need time to calm down before they begin to speak to this person. That’s normal and should be allowed in a relationship.

What Is a Light-Year? How huge? Light moves at 186,282 miles per second, or 299,792.5 kilometers per second. That's 670.6 million miles an hour. The distance to the nearest star is 4.3 light-years, or 25.3 trillion miles (40.7 trillion km). The first mention of light-years dates back to 1838 and a German scientist named Friedrich Bessel.

Light travels at a speed of 3.00 x 10 ^10 cm/s. What is the speed of light in kilometerss/hours? I originally gave the answer, but after reading guanotwozero's answer, I agree that guidance is more valuable than a simple answer, so I've retracted it. But if you've already been through school and just want a quick answer, Google will convert any measurement into another measurement of the same kind.

Light-second The light-second is a unit of length useful in astronomy, telecommunications and relativistic physics. It is defined as the distance that light travels in free space in one second, and is equal to exactly 7008299792458000000♠299792458 metres (just over 7005186282000000000♠186282 miles).

Light travels at a speed of 3.00 x 10 ^10 cm/s. What is the speed of light in kilometerss/hours? Best Answer: Ok so first you have to figure out what is 3.00 x 10^10 cm/sec. This is 3.00 x 10,000,000,000 which equals 30,000,000,000 cm/sec. Ok so first, convert seconds to hours. Now, convert centimeters to meters to kilometers.

The Coldest Place in the Universe The speed of light, as we've all heard, is a constant: 186,171 miles per second in a vacuum. But it is different in the real world, outside a vacuum; for instance, light not only bends but also slows ever so slightly when it passes through glass or water.

How fast was Voyager 2 going when it left our solar system, and, at that speed, how long to the closest star? The nearest star, Proxima centauri is 4.22 light years away. Light travels at a speed of 186, 000 miles/sec. = 186,000 x 3600 x 24 x 365 = 5.865 trillion miles per light year. To travel the distance of one light year, Voyager will have to travel for 5.865 trillion miles/(35,000x 24 x 365) = 19,130 years.(Another way to calculate is speed of light/sec divided by speed of voyage/sec = 186,000/(35,000 X 3600) = 19,130 years). For 4.22 light years = 4.22 x 19,130 = 80,730 years.s of August 10, 2007, Voyager 2 is at a distance of around 83.5 AU from the Sun, traveling outward at roughly 3.3 AUs a year. A light year is 63,240 AU-the nearest star is Proxima Centauri at 4.3 light years (therefore 271,932 AU away). Voyager is already 83.5 AU from the sun, so Prox. Cent. would be 271,847 AU away.

How Fast Does Light Travel? | The Speed of Light He concluded that light took ten to eleven minutes to travel from the sun to Earth, an overestimate since it in fact takes 8 minutes and 19 seconds. But at last scientists had a number to work with — his calculation presented a speed of 125,000 miles per second (200,000 km/s).iew full size image. The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph.

- The speed of light is about 186,000 miles or 300,000 kilometers per second. So, in one year light travels a distance of about 5,880,000,000,000 miles or 9,460,000,000,000 kilometers or 63,240 A.U.. This distance is 1 light-year.For example, the nearest star to us is about 4.3 light-years away.he speed of light is about 186,000 miles or 300,000 kilometers per second. So, in one year light travels a distance of about 5,880,000,000,000 miles or 9,460,000,000,000 kilometers or 63,240 A.U.. This distance is 1 light-year.

4 cosmic phenomena that travel faster than the speed of light When Albert Einstein first predicted that light travels the same speed everywhere in our universe, he essentially stamped a speed limit on it: 670,616,629 miles per hour. But that's not the entire story. In fact, it's just the beginning.

Speed of light The finite speed of light also limits the theoretical maximum speed of computers, since information must be sent within the computer from chip to chip. The speed of light can be used with time of flight measurements to measure large distances to high precision.n 1983, the metre was redefined in the International System of Units (SI) as the distance travelled by light in vacuum in 1/ 7008299792458000000♠299792458 of a second. As a result, the numerical value of c in metres per second is now fixed exactly by the definition of the metre.

- Saalim — A fundamental axiom of special relativity is that the measured speed of light as seen by any observer anywhere in the Universe is always 299,792,458 meters/second, a figure usually denoted by the symbol c. That statement is true regardless of any relative motion between the observer and the light source [such as a distant star].
