Q:

# How do you levitate?

A:

Actual levitation would require an invisible force holding a person aloft against the Earth's gravity, which is impossible. The equivalent amount of energy, even if Jedi mind powers were real, would completely fry the brain and nervous system. Therefore, levitation as seen in magic shows is completely staged.

There are some New Age traditions that claim to teach the ability to move energy throughout the body. Some people who practice these beliefs operate on the notion that moving energy is fundamentally the same as moving matter because of a misinterpretation of the e= mc^2 equation, or energy is equal to mass in grams multiplied by the square of the speed of light (300,000 meters per second). Although mass and energy are intertwined, the sheer amount of energy required to move mass with nothing but the power of the mind is mind-boggling. For example, a human weighing 50 kilograms would have to somehow exert 45 * 10^10 joules of energy, not even counting Earth's constant gravitational pull of 9.8 meters per second. Telekinesis via human brain power is not something that conforms to the laws of Newtonian physics. It is fun to fantasize flying through the air, but nowhere in the realm of reality.

The value 9.8 m/s^2 is the average acceleration of a falling object due to the force of gravity on Earth. The letter g represents this value the formula v=gt. With this constant and formula, the speed of an object is calculated at the time t in seconds after it is dropped.

The gravitational force of Mars is 38 percent of Earth's gravity. This low gravity is due to the fact that Mars only possesses 11 percent of the Earth's mass and 15 percent of the Earth's volume. The planet's significantly lower mass and size reduces the gravity it exerts on objects.

The force of gravity on Earth is approximately 9.8 m/s2. The exact gravitational force, which is described as the acceleration of gravity, differs based on latitude and altitude of a specific point on Earth. For example, gravity at the North Pole is 9.832 m/s2 and the gravity in New York is 9.803 m/s2.
