# Does time go faster in a plane?

When you fly, time slows down for you: here's how to calculate how much. We're all aware that when we fly across time zones, our clocks shift. Furthermore, time passes quicker in the absence of a gravitational field, according to Einstein's General Theory of Relativity. But what about over short distances? That depends on how fast you are traveling.

If you're flying from New York to San Francisco at an altitude of 10,000 feet (3,048 m), you're traveling at about 1,080 miles per hour (1,728 km/hr). Time passes more slowly for you because there is less distance for your clock to travel. At this speed, it would take you just under three hours to reach California from New York; but since you traveled at a constant speed, it also means that the same amount of time has passed for you as well.

But if you were to travel at twice this rate, that is, at 2,160 miles per hour (3,520 km/hr), then it would only take you about one hour and forty-five minutes to cover the trip. So even though you're moving farther away from Earth every second, it doesn't matter because you're going so fast that it seems like the same amount of time has passed for you as well as everyone else on Earth.

The reason for this is called "time dilation".

## Does a plane travel faster going east or west?

The jet stream is the primary cause of the disparity in journey time. Because the jet stream winds flow from west to east, planes travelling east may take advantage of the fast flowing winds and catch a ride on this atmospheric river. A plane traveling west, on the other hand, would be flying against the wind. This adds time to the trip because the pilot has to wait for a break in the clouds before taking off.

Another factor that affects how far a plane can fly is fuel efficiency. The Boeing 767 is more efficient at flying while carrying a full load than the Boeing 777-300ER is. This means that the 767 can travel further between refueling stops. However, the 777-300ER can stay in the air for longer without refilling its tanks.

Finally, there is the issue of cost. The farther a plane has to go to reach its destination, the more expensive it will be to transport passengers. Flights between Europe and Asia tend to be much more expensive than others because they must pass through multiple countries with different regulations regarding maximum flight times and fuel efficiency standards.

All things considered, eastbound flights are faster but westbound flights are longer. There are many factors involved in determining how far a plane can travel and what kind of transportation is available at each airport. But regardless of the route you choose, let someone know where you're going and when you'll be back.

## Does time move slower at sea level?

As you come closer to the Earth, time slows down because, as Einstein proposed in his theory of general relativity, the gravity of a big object, such as the Earth, warps space and time around it. This "time dilation" effect was initially detected on a cosmic scale, such as when a star passes close to a black hole. But it can also be observed on a smaller scale, within our own planet. Scientists have now shown that time moves more slowly near the surface of Earth than it does high up in the atmosphere.

At the top of Mount Everest, where the air is thin and the pressure is high, time flies by faster than low down, where it's thicker and the pressure is lower. The reason for this has to do with the effects of gravity. As we know, gravity gets stronger the closer you get to the earth's center, so this area of the world will feel a greater force of gravity than other places away from the center. This means objects closer to the ground will be affected by gravity more than those same objects high up in the sky.

In addition, closer to the ground, the path that light takes as it travels through space and time is longer. For example, if someone shoots you with a laser pointer, your eye sees it as moving quickly because the beam of light travels only a short distance but appears to take long due to the fact that time is passing more slowly near the ground.

## Why do objects travel so fast in space?

The speed with which an item moves through space reflects how much of its motion through time is diverted. The quicker it goes through space, the more its motion is diverted away from travelling through time, which causes time to slow down. For example, if you were to jump off a bridge and watch yourself fall, you would see that you are able to control your velocity as you fall toward the ground. This is because any object's movement through space is also its movement through time: as you increase its distance from the origin of time, time appears to slow down.

As long as an object is not moving too fast, the way to increase its distance through time is simply to go higher. So, if you want to make something travel faster, build a tower! The closer together the objects in the tower are, the greater their combined mass will be, and the more gravity will pull them downward. Thus, they'll move through space more quickly, leaving more time for them to travel through than those lower down.

If you drop something from a high enough point, it will travel so fast that time seems to stop for it. This happens because at some point, the object's distance from the origin of time exceeds the limit of what can be supported by Earth's atmosphere. At this point, no air molecules will be close enough to the object to feel its force, so it will fall like a rock.
