Does Size Affect time?
Time is not relative to size, but the size of an object does affect the comparative time rate of its various parts. So what does directly affect time? Mass and Acceleration - either of these will slow time.
Gravitational time dilation occurs because objects with a lot of mass create a strong gravitational field. The gravitational field is really a curving of space and time. The stronger the gravity, the more spacetime curves, and the slower time itself proceeds.
This so-called "time-dilation" effect is a consequence of Einstein's theory of general relativity, which posits that the gravity of a massive body – such as the Earth – warps the space-time around it, causing the flow of time to speed up or slow down depending on its distance from the mass.
In short, the proposed theory is that the experiences of time slowing down are related to the increased speed of internal processes: when we become faster, the world appears slower to us.
Our results show that the size of an object affects the perception of its speed. In particular, smaller objects appeared to move faster in translational motion.
Unlike the Twin Paradox, time dilation isn't a thought experiment or a hypothetical concept––it's real. The 1971 Hafele-Keating experiments proved as much, when two atomic clocks were flown on planes traveling in opposite directions.
But NIST physicists have made it a lot more personal - a scale of about 1 foot - and showed that you even age faster if you are taller than your relative. The good news is you won't be able to see the difference, that one foot difference in height adds about 90 billionths of a second over a 79-year lifetime.
Time as a proportionate to memory
So, why does time go so fast as you age? Put in the simplest terms, one of the most prevalent explanations is that our perception of time is inherently linked to how much time we have already lived - ie the older you get the more memories and experiences you have to draw on.
In a new study published today in Science, researchers used atomic clocks accurate to within one second in 3.7 billion years to show that gravitational fields also affect time on a much smaller scale. Basically, your head ages faster than your feet -- unless you spend most of your time hanging upside down.
Albert Einstein's theories of relativity that the further away from the Earth you are, the faster time passes works even on a human scale. That means - even though the differences are tiny - people will really age faster if they live on the top floor of a skyscraper than in a bungalow, the Telegraph reported.
Does time vary with height?
According to Einstein's theory of relativity, time moves differently depending on where you are in a gravity field. For example, a clock on top of a tall mountain will move a tiny bit faster than a clock at the base of that mountain, where the gravity is stronger.
Explanation: The clocks in space tick more slowly than clocks on Earth., HENCE COVERING LESS TIME AS COMPARED TO EARTH IN THE SAME DURATION. 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.
In order for you to stop time, you would have to be traveling infinitely fast. Nothing can travel faster than light (let alone infinitely fast) without gaining infinite mass and energy, according to Einstein's theory of relativity.
Unexpectedly pleasurable events boost dopamine release, which should cause your internal clock to run faster. Your subjective sense of time in that case grows faster than time itself, so that short intervals seem longer than they are.

Increasing the weight in any fixed friction environment will always decrease the speed with a given applied force.
Weight is a factor in all aspects of aircraft performance. Stall speed, maximum range airspeed, maximum endurance airspeed, maximum distance and minimum sink glide speeds, rate of climb, and manoeuvring speed are all examples of aircraft performance tied directly to aircraft weight.
Adding extra weight to your car will slow acceleration, but won't reduce its top speed. In determining a car's top speed, its engine battles two main forces: rolling resistance and aerodynamic drag. At very high speeds, air resistance makes up the vast majority of the overall drag on your car.
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.
One of the many implications of Einstein's special relativity work is that time moves relative to the observer. An object in motion experiences time dilation, meaning that when an object is moving very fast it experiences time more slowly than when it is at rest.
How much slower do you age in space?
Scientists estimate that the heart, blood vessels, bones, and muscle deteriorate about 10 times faster in space than in natural aging.
Your Height Changes All Day Long
You're tallest when you wake up and you may be as much as one centimeter shorter by the day's end. “The discs in your spine get compressed from being upright all day,” says Todd Sinett, DC, a New York City-based chiropractor and author of The Truth About Back Pain.
Height loss is related to aging changes in the bones, muscles, and joints. People typically lose almost one-half inch (about 1 centimeter) every 10 years after age 40. Height loss is even more rapid after age 70. You may lose a total of 1 to 3 inches (2.5 to 7.5 centimeters) in height as you age.
Height plays no significant factor in a person's ability to grow muscle. Whilst shorter people may appear to have gained more muscle in less time, it's simply because they need less muscle to fill out proportionally. In contrast, a taller individual with longer limbs may take more time to fill out.
The simplest answer is: no, an object's weight usually will not change its falling speed. For example, you can test this by dropping a bowling ball and a basketball from the same height at the same time--they should fall at the same speed and land at the same time.
Thus, more massive objects fall faster than less massive objects because they are acted upon by a larger force of gravity; for this reason, they accelerate to higher speeds until the air resistance force equals the gravity force.
Time dilation is triggered by disparities in both gravity and relative velocity. Together these two factors are at constant play in the case of a spacecraft's crew.
More massive objects will only fall faster if there is an appreciable amount of air resistance present. The actual explanation of why all objects accelerate at the same rate involves the concepts of force and mass.
Moreover, given two objects of the same shape and material, the heavier (larger) one will fall faster because the ratio of drag force to gravitational force decreases as the size of the object increases.
Acceleration of Falling Objects
Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.
Does being heavier make you fall faster?
Answer 1: Heavy objects fall at the same rate (or speed) as light ones. The acceleration due to gravity is about 10 m/s2 everywhere around earth, so all objects experience the same acceleration when they fall.
First, as height increases, the body's center of gravity shifts towards the higher point, which makes it harder to stay upright when falling. Second, taller people tend to have longer legs and arms, which gives them more time to react to a fall and avoid injury.
The distance the object falls is given by the following formula: h = 1 2 g t 2 , where is height is time, and is gravity.
Heavier skydivers will fall faster
The heavier the skydiver's body the faster it will fall toward the ground due to greater terminal velocity. This is evident from the equation of terminal velocity.
