Mount Nevado Huascarán in Peru has the lowest
Gravity is what holds our world together. However, gravity isn't the same everywhere on Earth. Gravity is slightly stronger over places with more mass underground than over places with less mass. NASA uses two spacecraft to measure these variations in Earth's gravity.
If the earth were about 36,000 km in diameter with the same mass and length-of-day then the gravity at the equator would be zero. This is the altitude of geostationary orbits.
If you wanted to reach a point where Earth's gravity no longer has a hold on you, you'd have to fly out about 21 million kilometers, or 13 million miles.
Did you know that your weight is different depending on where you are on the surface of the Earth? While the Earth has an average gravitational force, different locations on Earth have gravitational forces that are larger or smaller than average. This is because each location has more or less mass than the average.
The equator is moving quickly as the earth's spins, so it has a lot of centrifugal force. In contrast, the poles are not spinning at all, so they have zero centrifugal force. Since centrifugal force points outwards from the center of rotation, it tends to cancel out a little bit of earth's gravity.
gravity is significantly less on high mountains or tall buildings and increases as we lose height (which is why falling objects speed up) gravity is caused by the Earth spinning. gravity affects things while they are falling but stops when they reach the ground.
Can you Age less if you live in an environment with more Gravity? No, definitely not. Clocks tick slower in more gravity, but the time on clocks has nothing to do with aging. The force of gravity is the cause of motion and stress that causes physical age.
So depending on our position and speed, time can appear to move faster or slower to us relative to others in a different part of space-time. And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That's because of time-dilation effects.
"Gravity makes us age slower, in a relative term," Chou said. "Compared to someone not near any massive object, we are aging more slowly by a very tiny amount. In fact, for that someone, the whole world around us evolves more slowly under the effect of gravity."
As you go down below the Earth's surface, in a mine shaft for example, the force of gravity lessens. Weight and gravitational pull continue to decrease as you get closer to the centre of the Earth.
So what exactly is the escape velocity from the surface of the Earth? It is a whopping 11.2 km/s (kilometres per second).
Where does space begin? For purposes of spaceflight some would say at the Karman line, currently defined as an altitude of 100 kilometers (60 miles). Others might place a line 80 kilometers (50 miles) above Earth's mean sea level.
A consequence of the shape of the Earth as an oblate spheroid is that there is a significant variation in the absolute gravitational acceleration at the Earth's surface between 9.780 m/s2 in northern Australia and 9.805 m/s2 in southernmost Tasmania (Figure 5.3).
When the ice began to melt, about 21,000 years ago, the Earth began to spring back, but, like a Nerf ball, it takes a while. To this day, the Earth in the Hudson Bay region is still deformed, with lots of rock-mass having been pushed outward by all the ice. Less mass means less gravity.
And one such place, without a doubt, is the Hoover Dam located in the United States. What's so special? Well, the speciality of this place is that gravity doesn't work here. It's almost the opposite here, for once you throw something up in the air, it doesn't fall but starts floating in the air.
Explanation: The clock in space ticks slower than the clock on Earth, hence LESS TIME than Earth in SAME TIME. One hour on Earth equals 0.0026 seconds in space. Thus, by our calculations, we find that one hour on Earth is equivalent to seven years in space.
Despite the lack of gravity, periods happen normally in space and do not cause 'reverse flow' as once feared. Pictured, NASA astronaut Sally Ride (1951 - 2012) is pictured inside the Challenger space shuttle in which she became the first American woman in space in 1983 -- 20 years after Valentina Tereshkova.
Other astronauts have described it in similar yet varying ways: "burning metal," "a distinct odor of ozone, an acrid smell," "walnuts and brake pads," "gunpowder" and even "burnt almond cookie." Much like all wine connoisseurs smell something a bit different in the bottle, astronaut reports differ slightly in their " ...
AGE DECLINE is a medical condition of Body Chemistry that begins decline shortly after you 40s. But by the time you hit 60 many of your immunities and body helpers are nearly gone.
Experts say our perception of time greatly changes as we age, which makes certain periods feel like they go by quickly. For many people, 2022 went by in a blink ― doesn't it feel like it was just January? But for others, especially children, last year's holidays may seem like eons ago.
Changes to time and distance. Perhaps one of the most famous effects of special relativity is that for a human moving near the speed of light, time slows down. In this scenario, a person moving at near light speed would age more slowly. This effect is called time dilation.
A firm believer in the theory of the expanding universe, he also believes that gravitation gets weaker as the universe expands and permits gravitational forces to penetrate more space. By his guess, the force of gravitation is about 13% less today than when the earth was formed 4½ billion years ago.
A black hole is a region of space, where gravity is so strong that nothing can escape from it, not even light. It has the strongest gravitational pull in the entire universe.
According to string theorists' best ideas, gravity is so weak because, unlike the other forces, it leaks in and out of these extra dimensions. We only get to experience a dribble of the true strength of gravity.
