How do you explain time dilation?
Time dilation is the phenomenon of time passing slower for an observer who is moving relative to another observer. Suppose, for example, an astronaut measures the time it takes for light to cross her ship, bounce off a mirror, and return.
What is time dilation in simple words?
time dilation, in the theory of special relativity, the “slowing down” of a clock as determined by an observer who is in relative motion with respect to that clock.
How fast do you have to go to notice time dilation?
The effects of time dilation only start to become apparent at speeds close to the speed of light (300,000 km per second, or 186,300 miles per second). For more detailed information on time dilation see this page, and you can find a time dilation calculator here.
Why is time slow in space?
That’s because of time-dilation effects. First, time appears to move slower near massive objects because the object’s gravitational force bends space-time. Public Domain The phenomenon is called “gravitational time dilation.” In a nutshell it just means time moves slower as gravity increases.
Does light feel time?
Photons do not experience time. From the perspective of a photon, there is no such thing as time. It’s emitted, and might exist for hundreds of trillions of years, but for the photon, there’s zero time elapsed between when it’s emitted and when it’s absorbed again.
Why time is slower at speed of light?
Space itself is shortened and time itself is slowed down for a moving reference frame, relative to the stationary observer. 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.
Is it true that 1 hour in space is 7 years on earth?
The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.
What is the actual cause of time dilation?
Time dilation doesn’t just occur because of relative motion, it can also occur because of gravity . Einstein’s theory of relativity says that gravity is a property of the warping of space and time. So when you have a mass like Earth, it actually warps space and time.
What do I Understand About Time dilation?
Relative Velocity Time Dilation. The time dilation seen due to relative velocity stems from special relativity.
What are examples of time dilation?
An Example of Time Dilation. A spaceship is flying a distance of 5 light hours, for example from Earth to the dwarf planet Pluto. The speed can be regulated with the upper buttons.
What are the effects of time dilation?
Dilation is harmless in the long term, but it does come with short-term side effects. These will usually last for about four to six hours. Side effects of dilation include: light sensitivity. blurry vision. trouble focusing on close objects.
