Interesting Facts about SPACE!

SPACE

WHILE SAYING ABOUT SPACE,  WHAT IS COMING ON  YOUR MIND?

                          I think so, all your mind would think about black-dark empty space, some galaxies, rocket, spaceships and few may thought about solar system and it's planet's. But not only this, the SPACE contains enormous of Mysteries things which is apart from human thought's. While we knowing about it's just 1% itself, it make us more surprise and amazing. 

So, for that only human's were, more curiosity to explore more about space. And spending their money and time on it. Once upon a time, there is a huge war between America and Russia about space exploration, that war named as "cold war". 

"DARK MATTER"

                   One of the recent researches about "DARK MATTER" and it's one of the most mysteries thing in our space. It is a form of matter thought to account for approximately 27% of the matter in the universe and about 27% of it's total mass-energy density or about 2.241x10^-27 kg/m^3. Most dark matter is thought to be non-baryonic in nature; it may be composed of some as-yet undiscovered subatomic particles.

"SPACE AND IT'S DIMENSIONS"

                       Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime.

"OBSERVABLE UNIVERSE AND IT'S ESTIMATED GALAXIES"

                 

 First of all, what is observable universe?

                                            Observable universe is nothing but, the outer space region how much the we can able see or observable by telescopes and exploratory probes at the present time, otherwise we can say it as the light particles (it may be photons or electromagnetic radiations) how much can get travel and reflected by other Galaxies and Universe, that region is named as Observable Universe.

This observable universe is a spherical region of the universe comprising all matter that can be observed from Earth or it's space.

"In the below images would clearly shows the region of Observable Universe".

        In the observable universe there are an estimated 2 trillion (2,000,000,000,000) galaxies. The International Space Station is the largest ever crewed object in space. Spacecraft have visited all the known planets in our solar system.

               You may ask, what is behind the observable universe; behind this region Scientist has named it as Unobservable universe, which ought to look just like the part we can see. The way we know that is through observations of the cosmic microwave background and the large-scale structure of the universe.

It would be estimated as, at least 7trillion light-years across.

               Scientist have strong belief that the reflected light particles would show about the Big bang theory. From that we can able to know more about, how our Solar family would created.

"SPACE-TIME RELATIVITY"

The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity. Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to other forces of nature.

This Einstein's special relativity says that time slows down or speeds up depending on how fast you move relative to something else. Approaching the speed of light, a person inside a spaceship would age much slower than his twin at home. Picture a four-dimensional fabric called space-time. This relativity also shows the time dilation.

The below experiment shows the Space-Time relativity and how it relate with gravity also the space time sheet.

"SPACE JUNK"

                   Space junk is any human-made object orbiting Earth that no longer serves a useful purpose. Scientists estimates there are about 500,000 pieces of space junk today, including fragments from rockets and satellites, and everyday items like spanners dropped during construction of the international Space Station!.

"NEUTRON STAR"

                    Another amazing fact is about Neutron star, It can spin at a rate of 600 rotations per second. Neutron stars are one of the possible evolutionary end-points of high mass stars. They're born in a core-collapse supernova star explosion and subsequently rotate extremely rapidly as a consequence of their physics. Neutron stars can rotate up to 60 times per second after born. Under special circumstances, this rate can increase to more than 600 times per second.

"SPACE IS COMPLETELY SILENT"

                       Space is completely silent; Sound waves can't able to travel without any medium. Since, there is no atmosphere in the vacuum of space, the realm between stars will always be early silent.

That said, worlds with atmosphere and air pressure do allow sound to travel, hence why there's plenty of noise on Earth and likely other planets as well.
