The Mysteries of Relativity

Objects that Decreases in Length

According to the theory of relativity an object moving in the direction of motion decreases in length as the speed increases until you get to cancel when it reaches the speed of light in vacuum.

The mass of an object increases with speed

The mass of a moving object increases as it gains speed up to be infinite at the speed of light. The first experimental verification of this effect occurred in the Stanford Linear Accelerator (more than three kilometers in length), in California, which were accelerated electrons, which already close to the speed of light had its mass increased by 40,000. Loosely speaking, a soccer ball that weighs about 450 grams if it is accelerated at speed near the speed of light can weigh more than the Sun!

The Rhythm of Time of a Body Decreases as Speed Increases

This effect of relativity is true also with increasing speed until the passage of time stops completely when the body reaches the speed of light. This unusual phenomenon has given rise to the twin paradox: if a brother of a pair of twins make a trip in a spaceship with nearly the speed of light, returning to Earth, would be younger than his brother who stayed here during the same time . This is not fiction. It is an effect of relativity that has been verified experimentally. A high-precision atomic clock in orbit of Earth shows sensitive time differences with respect to a stationary clock synchronized with the same on the soil. The science fiction film Planet of the Apes will no longer be fiction if in the future the man will travel at speed near the speed of light. It should be remembered that the theory of relativity prohibits a body has the same speed of light, but the equation shows that relativistic mass can exceed the speed of light, which would give rise to tkeons particles so far not observed in Nature. That would allow travel into the past, giving rise to the grandfather paradox: a person could travel to the past and kill your grandfather, but if that happened she would not have been born. Also the trip to the future could be through holes called wormholes which would allow travel between parallel universes, if they exist. The time machines are feasible in unorthodox situations. An other example of the relativity of time is the interplanetary communication. When man land on Mars the space centers controllers on Earth will only receive the confirmation of the landing just 20 minutes later; a 'hello' received from the astronaut in the Martian soil is already a past event, but for us it is present. When we look at the sky we are looking to the past. A star may no longer exist, what we see are photons that come out of it for years, thousands of years, millions of years, or even billions of years if it is a galaxy, a quasar, or a neutron star; the black holes appears only by indirect evidence. The Hubble Space Telescope has photographed galaxies that are at the beginning of time, according to the Big Bang model.
