How long would it take to get to earth from the sun traveling at the speed of light?

The distance between planet Earth and the Sun is 149,597,892 kilometers
The speed of light is 299,792,458 meter per second
149,597,892,000 m / 299,792,458 m/s = 499,00
It would take 499 seconds = 4 minutes and 19 seconds

∙ 6y agoBy definition, a light-year is the distance light travels in one year. That means that light travels at the rate of 1 light-year per year; and to travel to (or from) a star that is 640 light-years away, it would take 640 years.Note that this calculation is no longer accurate for objects that are billions of light-years away: by the fact that while the light from such far-away sources comes to us, the Universe in between is expanding.

What is the speed of light at 30 degrees?
That would depend on the medium which the light is traveling through.
Traveling at speed of light how much time will pass in 70 years on earth?
None. At the speed of light, time stops completely. It is impossible for anything with an invariant mass to move at the speed of light; only particles with no "rest mass" (such as photons) can do so.
What is a light year and explain it using a suitable example which talks about position of stars?
A light year, is the distance that you would travel in one year if you were traveling at light speed. It is equal to about 6 trillion miles and 9 trillion kilometers. It doesn't really deal with the position of the stars but their distances from earth. Example: Sirius is about 8 light years from earth. If you traveled at light speed in its direction, you would arrive in about 8 years.
If you traveled at the speed of light how long would it take you to reach earth's nearest star?
Actually, the closest star to Earth is Sun which would be reached in a little more than 8 minutes.As for other stars, closest one is Proxima Centauri. You'd need to travel for 4 years and 2 months to reach it at the speed of light. You may or may not know that you have asked a delightful trick question. If I were traveling at the speed of light [impossible, of course] how long would it take me to get to earth's nearest star? From my point of view, the trip would be instantaneous. It would also be an instantaneous trip if I traveled to a destination 100 million light years away. Time completely stops at light speed. Observers on earth would conclude that the trip took me 8 minutes. We would all be right, within the scope of our individual frames of reference.
How does traveling at light speed negate time?
Answer:In fact light speed is not the question you should be asking. It should be "when traveling at the universal speed limit, why does time slow down." The answer is that no matter how fast you are traveling the universal speed limit (equal to light speed because it goes max speed) is viewed the same. The theory is that all clocks/measuring devices are morphed in the same way so that when it measures the speed limit it is still the speed of light (universal speed limit)AKA, all clocks, even biological, are slowed down as it travels faster through space time. So your perception is slowed and your recognition of this perception is slowed, so for you time appears the same. If you travel 95% the speed of light and flick on a light, it wont travel 5% the speed of light away from you, it will travel 100% the speed of light away from you due to your space time warping. This also happens the nearer you are to a large mass. aka a black hole. It also warps the space time around you.Alternate points of view... Take for example, you are traveling in a car at any speed. You pass cars traveling slower than you are. They appear to travel backwards. This is of course only relative to YOU. They are actually traveling forwards. If you think of yourself in the car as the speed of light, and the other cars as time, that's how it works. Of course, light travels SO fast that it bends TIME only relative to YOU. It's not like the whole world actually stops or slows down. It's only you who feels it. Just like overtaking a car. But that's only a simple explanation.In laymans terms, traveling at light speed means that you are traveling at a speed greater than the speed of time. Therefore time is at a fixed rate, and the speed that light travels is at a fixed rate also. So to travel light speed actually gives you an advantage over time itself. It has been mathematically determined that the longer you travel at this speed, the more advantage you gain, so it would be possible for a child to travel at this speed for a computed time, and return to see that several generations have passed while he/she would have only aged the number of days / months traveled in spaceship time.Another layman's view:Traveling at light speed really doesn't negate time. It is just that time is relative, as is velocity. My computer seems motionless to me, but an observer looking down at the solar system would see me and my computer moving quite rapidly. If you could get into a ship and accelerate to very near the speed of light and travel for ten earth years, your personal experience of time will not seem to you to have been any different from when you were on earth. Every moment would have passed normally for you, without anything seeming odd. It's just that at the end of the trip, you will have experienced it as only a fraction of the ten years. It will seem impossible to you that 10 years has gone by on earth. Time will have gone by differently for you than for earth. The same thing would happen even if you could reach the velocity of light. Upon decelerating, you would not report anything unusual regarding your experience of the passage of time; time will have passed for you as normally as ever. But you will notice that you spanned a huge distance instantaneously. You would find it nearly impossible to believe that dozens, hundreds or thousands of earth years had passed by during that instantaneous surge. From your vantage point in that ship, you could as easily ask: How does traveling at light speed accelerate time (for earth)? It doesn't.
How long would it take to get from earth to Uranus traveling at the speed of light?
3 days
How long would it take to get to the moon if you were traveling from the Earth at the speed of light?
About 1.5 seconds
How far back in time would you go if you traveled the speed of light?
To an outside observer a person traveling at the speed of light would be frozen in time. To the person traveling at the speed of light, things would seem normal.
When a body of some mass travels with a speed of light and hits the earth then what happens to the earth?
The mass of a body increases as its speed increases. A body that has any masswhen it's not traveling at the speed of light would have infinite mass when it istraveling at that speed. So its kinetic energy would be infinite, and anything it hit ...whether a bird, a plane, the Earth, or a star ... would be totally blasted to smithereensthat were too small to detect.Fortunately, a body that has any mass when it's not traveling at the speed oflight can never travel at that speed.
What is the speed of light at 30 degrees?
That would depend on the medium which the light is traveling through.
How long does it take to travel 600 light years?
It really depends on your speed. If you were traveling at the speed of light, it would take 600 years. 600 light years equals 3,527,175,223,910,165 miles. So divide that by the speed you would be traveling to get the length of time it would take you.

How many light years from earth is mars?
Well traveling at the speed of light would take 4 minutes, so if you want to convert that to years...have fun :)

Why traveling at the speed of light would we disperse?
No such thing would happen. Matter cannot reach the speed of light, only massless things can (and they cannot travel at any other speed than the speed of light).
If you were traveling at the speed of light in a car what would happen if you turned on the headlights?
Nothing
Traveling at the speed of light how long would it take to get to the sun?
roughly 8minutes 20seconds
