In space everything obeys Isaac Newton's law of motion including light. When a body is set in motion in a vacuum accelerates to a maximum momentum speed limit. Acceleration is terminated to a constant. Despite no resistance is a maximum speed of just under 300,000km/s. ( 297,958.95km/s to be exact ) no matter how fast we go is always that distance ahead of us every second. We cannot catch up with it. Even if we travel at light speed light will always will be ahead of us by a distance of 300,000km.
If we think of light takes just under 8 minutes to reach earth the sunlight we observe right now, is just as the sun was 8 minutes ago every second. That means light leaving right now will be seen by our eyes 8 minutes in the future.
If we are able to travel at light speed we would accelerate from sub light speed to light speed. But would light would be 300,000km ahead of us. If we didn't stop we'd over shoot the sun traveling a distance of 300,000km every second away from it. We would have to decelerate to a sub light speed at some point. The common consensus we cannot travel faster than that. If we do the math's on this tells us to the sun from earth is not less than 8 minutes. We cannot get there any faster with out being faster then light.
Albert Einstein discovered Newton's law of motion where there is a force there is a opposite and equal force acting on acceleration. Petrol heads ( car mad ) people are familiar with acceleration specs such as 0 to 80kmph ( 50mph ) in a couple of seconds. We all don't have to be Einstein's to realize the implication of 0 to a160kmph (100mph) in a second. Think of a distance of a160km to a stop in a second let a lone 300,000km.
From our point of view of the environment's time would begin to slow down slowing down faster and faster until at some point would be going so fast we cannot observe time moving anymore. We have the illusion of stopped. As we hit the brakes we would observe what appears to be a frozen in time start to move again getting faster and faster as we slow down. Finally we will stop finding ourselves a second into the future where we left off 160km away. In other words the faster we accelerate the faster time goes and when we decelerate the faster time goes.
Mathematics tells us light would travel round the circumference of the earth just under 7 times in a second. From our point of view a blink of an eye. From light speed's point of view of the environment's time would appear to be stopped during every 7 times round the earth. The environment's would have only moved a second.
If we do the math's we realize time at light speed doesn't not stop at. The math's tells us every 7 times is a second. So a second is a second. So if light traveled round the earth in a minute is 60, environment seconds times 7comes to 420 times in that environment time. In a whole hour would be 3,600, 7's.
The environment's time would still be traveling all the seconds of every day, every week, every month, for years, a decades, centuries, a mellinea ( 1,000 years ), millions, billions even all the seconds in a trillion centuries and beyond every second 7 times round the earth. Imagine the number of times in a all the seconds in a several 100 trillion centuries times 7.
As light speed is a maximum speed limit light will not travel any faster than 7 times round the earth in every second constant. From light speed's point of view the environment could not travel any slower constant. Imagine if there was no such thing as a constant velocity. We think of an infinite velocity. That is perhaps not the right word as velocity implies a constant. We can think of a infinite acceleration to avoid the implication of a constant. Lets see what happens when we accelerate constantly 10 times the distance every second. Mathematics tells us from a standing start is a 0 distance. Reedy set.....go.
By the end of the first second we had traveled 1 meter. By the end of the second second we had traveled a 10 meters. By the end of the third second we had traveled a distance a100 meters and by the end of the fourth second we had traveled a distance of a 1,000 meters. Since there is a 1,000 meters in a kilometer we'd accelerated a distance of 1 meter,10 meters a 100 meters and 1,000 meters in 4 seconds flat.
By the end of the fifth second we'd traveled a distance of 10km. By the end of the 6th we'd traveled a100. By the end of the seventh second we'd traveled a 1,000km. and so on.0.001km, 0.01km 0.1km,1km, 10km,100km and a 1,000km in 7 seconds.
By the end of the 8th second we would have traveled 10,000km. Every second 10 times the distance we'd traveled a billion kilometers before a quarter minute.( 15 seconds ) let a lone half minute .Imagine the distance traveled in a full environment minute, let a lone all the seconds in an hour. Imagine all the seconds in a environment day, a week, in every month, in a year, a decade, a century ,millennium, million, billions even in trillions of centuries and beyond with no end to the acceleration.
