He has even broken "the rule of gravity," according to the poem. It's because he possesses levitation abilities, allowing him to glide and ascend in the air. Through such techniques, he instantly vanishes from the crime scene.
This ability is given to Macavity by the Egyptian god Anubis. When Macavity dies, his body becomes part of the sky and is allowed to float up into heaven.
In real life, this doesn't happen. However, there are people who claim to have done the same thing that Macavity did. They often do so by using certain rituals or methods. For example, a Scottish magician named Peter Grant claimed to have used magic to escape down a rabbit hole and appear in another place. He later admitted that this was simply for show. However, it shows that people have been able to break the rules of physics during their mortal lives.
Macavity breaks the rules because he's a fictional character. However, some physicists believe that it's possible for humans to achieve super-luminal travel if they develop certain technologies first envisioned by science fiction writers like Stanislaw Lem and Isaac Asimov.
He proposed that gravity occurs when space and time (which are the same thing) are twisted or distorted around a mass, such as a star or planet. As a result, a star or planet would generate a type of dip in space, causing any other object that approached too close to fall into the dip. This would create objects with orbits influenced by the star or planet.
Gravity also affects time. If there were no gravity, then clocks would run at the same rate everywhere, and we could use light signals to send information across large distances instantly. However, because all clocks are affected by gravity, they slow down as they get closer to the source of gravity and speed up as they get further away. This means that it takes more energy for a signal to travel far than if there were no gravity; so even though gravity allows us to communicate over large distances instantaneously, it also causes problems for any device trying to do so.
The math behind these ideas was done by Albert Einstein in his theory of general relativity. He showed that gravity is related to the curvature of space-time rather than just space by using equations called "geometric proofs" of some of his famous theories such as the equivalence principle which says that gravity is an effect of mass, not matter itself. Space-time is like a rubber sheet, and objects that have mass curve it into shapes. Other objects, such as light, can pass through these curves unimpeded.
A bird, an airplane, or even a super hero must employ other forces to overcome gravity before they can fly. Feathers and seeds, for example, fall slowly or even float in the air. Planes use wings that create forces that oppose the action of gravity.
Gravity can be opposed by massic force, as in the case of a rocket. Or it can be opposed by energy, as in the case of an elevator. The word "elevator" comes from the French autorité, which means "against gravity." Elevators use physics laws similar to those used by rockets to rise up into the sky but instead of burning fuel like rockets, they convert electrical energy sent down cables into upward force. An electric motor drives a screw that lifts up small weights attached to cages filled with rocks and sand. At the top of the tower is another motor that acts like a brake to stop the elevator at any height.
Elevators were first invented in 1851 by the American Cyrus Konefes. They came into popular use in 1880 when the Eiffel Tower was built in Paris. Today's skyscrapers use elevators instead of stairs because they are easy to maintain and safe.
Can anyone resist gravity using levitation, balancing, or magnetic devices? We can never escape the influence of gravity on the near Earth. Small items, on the other hand, can be levitated via a phenomenon known as diamagnetism. Although all matter is made up of atoms, some atoms possess properties that result in a large reduction of their magnetic moment. These are called "spin-zero" particles. They include electrons, neutrons, and certain types of atoms (such as hydrogen) with no nuclear spin. An example of an atom that has a net spin is iron; it has a magnetic moment, but it's not zero. Instead, it has a value of about 5/16 of a quantum per atom.
Any object with a significant mass will attract other objects with high force. This means that humans and animals can defy gravity if they are light enough. A human could, for example, be lifted off the ground by a series of cords tied to an overhead pulley. The human would need to be secured to the cords with a safety harness, though. It would be difficult or impossible to do any kind of work while being suspended like this, but it could be done.
The word "levitate" comes from the Latin word laurus, which means tree. Thus, someone who is able to lift themselves up out of the ground like this is really lifting themselves up into the air above terrestrial vegetation.
