A BIG BANG
Th Big Bang is that, astronomers explained the way that how the Universe started. The idea that the Universe started as a point and then expanded and expanded to evolve as it is now ( and it can still spread ).
WHAT IS DARK MATTER
The Dark matter account for about 85% of the matter in the universe and about a quarter of its total mass energy density, or about 2.241 x 10 power -27 kg / m3.
WHAT IS DARK MATTER MADE OF
Most of the scientists think that the dark matter is made of non-baryonic matter. The major candidate, WIMPS ( weakly interacting massive particles , is ten or one hundred times the mass of a proton, but their weak interaction with the ''normal'' case makes them difficult to detect.
WHY DARK MATTER IS SO IMPORTANT
The Dark matter is the most mysterious, non interacting substance in the Universe. Its gravitational effect are important and necessary to explain the rotation of the galaxies, the motion of clusters, and the largest scale structure in the whole entire Universe. ... Without the Dark matter, there is no sign of life in the Universe.
CAN WE SEE DARK MATTER
Unlikely to the normal matter, the dark mater does not interact with the Electromagnetic force. This means that it does not absorb, reflect or emit light, making it very difficult to spot. In-fact, the researchers are only able to infer the existence of the dark matter from the effect of gravitational on visible matter.
WHAT IS DARK ENERGY
The Dark energy is the unknown form of energy in physical cosmology and astronomy, that affects the universe on the largest scale.
WHY DARK ENERGY IS SO IMPORTANT
The '' Dark energy is not only very important for astronomy, it is a central problem of physics. It has been a bone in our throat for a long time ''. ... In the year of 1990s, he discovered a previously unknown '' dark energy '' that is causing the universe to expand rapidly as ages
HOW DID BIG BANG HAPPEN
The Universe began, scientists believe, to be jammed into a very small point with every spot of its energy. This extremely dense point exploded with unimaginable force, creating matter and spreading it outward to form billions of galaxies in our vast Universe. The astronomer termed the Titanic explosion as the Big Bang
WHEN WAS BIG BANG HAPPEN
The detail measurement of the expansion rate of the Universe was take place and made approximately 13.8 billion years before the big bang, which is considered the age of the Universe. After the first expansion or initial expansion, The Universe cooled sufficiently to allow the formation of sub-atomic particles and later atoms.
WHAT CREATED EARTH
For about 4.5 billion years ago when the Solar system settled into its current layout, Earth was formed when gravity pulled rotating gas and dust from the Sun and formed the third planet. Like its companion terrestrial Planets, the Earth has a central core, a rocky mantle, and a solid crust.
WILL THE UNIVERSE END
As long as the amount of stuff does not exceed a critical limit, the Universe will continue to expand forever , and eventually suffer from heat death. But if there is too much stuff, the expansion of the Universe will slow down and stop. Then the Universe will started shrinking
WHAT WAS THERE BEFORE BIG BANG
The initial singularity thought by the general relatively to come into existence before the big bang and encompass all the energy and life span of the Universe is a gravitational specificity.
HOW DID TIME BEGINS
Relatively, according to the general theory of space or the universe, emerged in the Big Bang about 13.8 billion year ago. ...In the theory of relatively, the concept of time begins with the Big Bang in the same way that latitude parallels at the North Pole.
WHO WAS THE FIRST PERSON ON THE EARTH
The oldest and earliest member of the genus Homo are Homo habilis which evolved for approximately 2.8 million year ago. The Homo habilis has been considered the first species for which there is clear proof and evidence of the use of stone tools.
HOW TO WRITE SPEED OF LIGHT
The speed of light in a vacuum, usually denoted by C, is a universal physical constant in mamny fields of physics. Its exact value is defined as 299792458 meters per second for about ( 300000 km /s or 186000 mi / s )
Miles per second : 186000
Metres per second : 299792458
One light year : 1.0 year
Miles per hours : 671000000
HOW TO CALCULATE ONE LIGHT YEAR
Multiply the number of second in a year by the number of miles or kilometers that light travels in one second, and there you will find the answer
It is about 5.88 trillion miles ( 9.5 trillion km )
