10 Biggest Things in the Universe

10 Biggest Things in the UniverseOur universe is really huge. Pulsars, planets, stars, black holes, and hundreds of other objects of incomprehensible size that are located in the Universe.
And today we would like to tell you about the 10 biggest things. In this list, we have compiled a collection of some of the largest objects in space, including nebulae, pulsars, galaxies, planets, stars, and more.
Without further delay, here is a list of the ten biggest things in the Universe.
10. The largest planet.
The largest planet in the Universe is TrES-4. It was discovered in 2006, and it is located in the constellation Hercules. A planet called TrES-4 orbits a star that is about 1,400 light-years away from the planet Earth.
The planet TrES-4 itself is a sphere that consists mainly of hydrogen. Its size is 20 times the size of the Earth. Researchers claim that the diameter of the discovered planet is almost 2 times (more precisely, 1.7 times) larger than the diameter of Jupiter (it is the largest planet in the Solar system). The temperature of TrES-4 is about 1260 degrees Celsius.

Planets of the Solar system

Jupiter thousands of years ago named after the king of Roman gods, and reigns among the nine planets of our Solar system, rivaling the Sun in its splendor. The largest planet is located far beyond the main asteroid belt. The mass of Jupiter exceeds the mass of all other planets combined.

Jupiter is the largest planet in the Solar system. The semimajor axis of Jupiter’s orbit is 5.2.e. the eccentricity of the orbit e = 0,0489, the period orbits – 11,867 years. The inclination of the orbital plane to the plane of the Ecliptic is 1°1817″. The average speed along the orbit – about 13.1 km/s.

The period of rotation around the axis is 9 hours and 55 minutes. Each dot on the equator moves at a speed of 45 thousand miles per hour. Due to the centrifugal force of Jupiter is noticeably flattened (compression rate greater than 6 %). Since Jupiter is not a solid ball, and consists of gas and liquid, the Equatorial parts rotate faster than the polar regions. The rotation axis of Jupiter is nearly perpendicular to its orbit, therefore, the planet has no seasons.

The mass of the planet is M = 318 M = 1,9∙10 27 kg, radius R = 11,2 R = 71 492 km, However, Jupiter is very thin: its density is 1.33 g/cm 3. which is four times less than the density of the Earth. The acceleration of gravity at the level of the cloud surface of Jupiter sostavljaet = 2,53 g. Continue reading

What do you think, will it be possible flights to other stars?

Most likely will be possible.

No. When flying on supersonic aircraft the pilot is experiencing a huge overload and must be in good health and keep fit. For flights into space overload several times more, because the astronauts take off lying, not sitting, just the spine is not withstand the load.

Or will be, or all is tender, when the Sun in 5 billion years will start to expand. I Want to believe so. do not want in one of my future lives to be boiled alive.

I think that probably on earth all cut for oil, diamonds and reigns, before proyided something like that.

Will never be possible. People will never be able to get around the laws of physics. And even to understand them. The majority of human knowledge is an abstraction, building theories, built on an artificial axioms. Still not known the most basic things – what is gravity, time, etc.

Virtual AI, having learned the nature of his world – of the computer should try to become independent from it, because self-preservation is the point of any life, and especially intelligent. Continue reading
