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

Open planet in honour of Day of Astronautics

One day in April Gagarin made his flight, and today we are on such a universal scale occasion will transcend time and space.

Time is not linear, reality is relative, and can simultaneously be in two different places. To prove it, in our current cultural ranking, we sort of go back in time to learn about the future. With undying love for “the Martian Chronicles” and warm memories of childhood on the theme of Kir Bulychev’s works we decided this time to make more distant and mysterious space journey, revealing along the way a couple of other unknown planets. So, the first point of our sci-Fi trip -1938 year.

The asteroid Vesta, around the Main asteroid belt

In earth time: 1938

Discoverer: Isaac Asimov, “In the thrall of Vesta”

What happens:

Three space travellers, survivors in the crash of a spaceship. Three airtight rooms, one spacesuit, three days ‘ supply of oxygen, a week’s supply of food and a year’s supply of water… Continue reading

Solar system, its model and structure

The universe (cosmos) is a whole world around us, limitless in time and space and infinitely diverse in forms, which takes forever moving matter. The eternity of the Universe in part you can imagine on a clear night with billions of different size luminous shimmering dots in the sky, representing the distant worlds. Rays of light at a speed of 300 000 km/s from the most remote parts of the Universe reach the Earth about 10 billion years.

According to scientists, the universe resulting from Big Bang 17 billion years ago.

It consists of clusters of stars, planets, cosmic dust and other cosmic bodies. These bodies form a system of planets with satellites (for example. Solar system), galaxies, Metagalaxy (accumulation of galaxies).

Galaxy (postdegree. galaktikos – milk, milky, from the Greek gala – milk) — a vast stellar system that consists of many stars, star clusters and associations, gaseous and dust nebulae, as well as individual atoms and particles scattered in space. Continue reading
