A clock in outer space moves more quickly than a clock on Earth. Heavy things like planets create a gravitational field that slows down time nearby. An example of gravity causing time dilation is that if an object is near a black hole its time will slow relative to that of time on earth.
When you're up in space hurtling around at light speed, time runs slower for you than it does for everyone back on Earth. Not only would your watch tick more slowly, but your heart rate would slow down, your breathing would slow down and your rate of aging would slow down.
One hour on Earth is 0.0026 seconds in space.
Thus, upon calculation we find that one hour on Earth is equivalent to seven years in space. Einstein's theory of Special Relativity stands as a explanation to this calculation.
Clocks on the International Space Station (ISS), for example, run marginally more slowly than reference clocks back on Earth. This explains why astronauts on the ISS age more slowly, being 0.007 seconds behind for every six months.
In space, one minute is measured by the exact amount of time it takes for a spacecraft or any other object in space to travel about 8,800 kilometers, which is the equivalent distance around the Earth's surface.
As a result, time is relative and directly affected by space/time stretching (time). Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.
on edge of Black Hole. Space and time are intertwined, called space-time, and gravity has the ability to stretch space-time. Objects with a large mass will be able to stretch space-time to the point where our perception of it changes, known as time dilation.
If he could have hopped aboard a spaceship traveling at 99 percent the speed of light in 1879--the year of his birth--he would be only 17 years old upon his return to Earth today.
Near a black hole, the slowing of time is extreme. From the viewpoint of an observer outside the black hole, time stops. For example, an object falling into the hole would appear frozen in time at the edge of the hole.
Previous research has shown that spending time in space causes bone density loss, immune dysfunction, cardiovascular issues such as stiffening of arteries, and loss of skeletal muscle mass and strength in both humans and rodent models. These changes resemble aging in people age on Earth, but happen more quickly.
As we know, there are 3,600 seconds in an hour. They mention in the movie that every hour on the planet is roughly 7 years in Earth time. 7 years is 221,000,000 seconds. Take 221,000,000/3,600 and you get roughly 61,400 seconds that pass on Earth for every second spent on the water planet.
Answer and Explanation: The ISS orbits the earth at speeds of approximately 17,000 miles per hour, which is considerably faster than the earth rotates on its axis. Therefore the solar day on the ISS is considerably shorter than the earth day at just over 90 minutes in duration.
Light travels nearly 300 million meters per second (300,000,000 meters/second =3×108 meters/second, four fifths of the way to Moon in one second). Therefore one second equals 300 million meters of light-travel time.
In the limit that its speed approaches the speed of light in vacuum, its space shortens completely down to zero width and its time slows down to a dead stop.
Constant Speed
So what does this sentence really mean? Surprisingly, the answer has nothing to do with the actual speed of light, which is 300,000 kilometers per second (186,000 miles per second) through the "vacuum" of empty space.
A black hole is an extremely massive concentration of matter, created when the largest stars collapse at the end of their lives. Astronomers theorize that a point with infinite density—called a singularity—lies at the center of black holes.
Well, even though black holes are extreme in many ways, they don't have infinite mass—and it's mass that determines the force of their gravity. Some black holes—known as stellar black holes. —have about the amount of mass that very massive stars do.
In zero seconds, light travels zero meters. If time were stopped zero seconds would be passing, and thus the speed of light would be zero. In order for you to stop time, you would have to be traveling infinitely fast.
If you travelled at the speed of light, how would you experience time? Travelling in space for three years at close to the speed of light would equal five years on Earth.
At any rate, the beam of light emitted by your flashlight would appear to reach the far wall instantly, as the speed of light is independent of your speed and would always be constant at about 300,000 kilometres per second in a vacuum.
At 99.99 percent of the speed of light, a craft traveling for one year would come back to a world that had aged more than 70 years in their absence. At 99.99999 percent of the speed of light, for a year, more than 2000 years would pass on Earth.
If there were a safe way to approach a black hole and see how it worked, it might look something like this. A new visual depiction of a black hole's impressive gravity by NASA reveals its warping of space and time.
Don't let the name fool you: a black hole is anything but empty space. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City.
So a black hole not only warps the space around it, but time too. “Time is going slower there by a factor of 1,000,” says Bakala. That means for every 1,000 days that pass on Earth – a little over three years – just a single day elapses on the black hole planet.
