Planets of the solar system.

Solar system – 8 planets and over 63 of the satellite, which are opened more often, several dozen comets and many asteroids. All cosmic bodies move in their precise directional trajectories around the Sun, which is 1000 times harder than any body in the solar system combined. The center of the solar system is the Sun – the star around which orbits the turning of the planet. They do not emit heat and not light, but only reflect the light of the Sun. In the solar system now officially recognized as the 8 planets. Briefly, in order of distance from the sun, we list them all. And now a few definitions.

A planet is a celestial body that must satisfy four conditions:

1. the body must revolve around the star (for example, around the Sun);

2. the body must have sufficient gravity to have a spherical or similar shape;

3. the body should not be near its orbit of other large bodies; Continue reading

Flight along cosmic strings

So far the only scientifically proven the possibility of interstellar travel is the acceleration of the spacecraft up to relativistic speeds (punctures and convolution space still remain purely speculative projects). The ship may abandon astronauts in suspended animation for a dozen or even a hundred light years and return them to Earth. But because of the relativistic slowing of Board time on earth will pass away not even the century and Millennium — and it is somehow not pleasing. In addition to other galaxies to get to, there’s no cryostasis will not help. But it is possible that the output is still there.

For 15 years Professor of theoretical physics at Imperial College London, Joao Magueijo develops the hypothesis of variable speed of light (Varying Speed of Light, VSL). However, he minded very little, since most scientists believe this idea is pure nonsense. But we are talking about science impossible, so will try to temper my skepticism.

VSL-models calculated in several ways. They all say that measured on Earth the speed of light in a vacuum is not an absolute constant, and only the lower limit of the speed of propagation of electromagnetic waves. In certain (frankly, vesimaailma) conditions may be many times 299 792 km/s. Continue reading

On the outskirts of the Solar system walk comets

Some comets, rotating now in the Solar system, were originally in other star systems and ended up here due to the fact that the Sun is their “kidnapped”.

To this conclusion came a group of astronomers from the North-West research Institute in USA.

“If the results of our models and calculations are correct, then many comets that are present now on the outskirts of the Solar system originally was not here,” says scientific specialist of the Institute’s Hal Levison.

From his point of view, a significant proportion of comets that are now in the zone of the Solar system known as the Oort Cloud is aliens from other star systems.

“We know that stars are formed in clusters. Sun was born inside a huge community of other stars that were formed from a single cloud of gas and dust. In this cluster the stars were so close to each other that were able to “steal” different objects, such as comets through its gravity,” he says. Continue reading
