Space:

Space is like three dimensional positions where all objects have different positions and directions. In past inventions it is divided in three parts or three liner dimensions although in modern inventions it is considered in free four-dimensional that is know as spacetime. The concept of space is made everybody scientist because everybody knows what is space? what is inside of space? what is space made of? why it look like black? and many questions are made at this time but over the time a scientist named Albert Einstein introduced his theory in 1905 which is space and time can be viewed in a single construct known as spacetime. In modern time this theory is very relatable to the concept of space so if anyone need to define space in his presentation in school or collage or interviews they pick this theory and performed very well. The theory is defined in words by Albert Einstein is space is looks like near to vacuum process it pick particles from ground as you see in space planets or stars, some radiations are compulsory in outer space such electromagnetic radiations, magnetic fields, dust and cosmic rays.


In space according to this theory the temperature in space is 2.7 Kelvin(-455 degree Fahrenheit) and in space hot objects move very fast but cold objects move slowly because hot things are create gas particles when it burn they make more pressure and moves fast but on the other hand cold objects don't make any kind of atoms to make pressure that's why they move slowly. In this time everyone think that why the space color is black so the answer is i tell you space is like vacuum meaning the universe is so big as we think so stars or planet are very far from each other that's why when we see in space a small stars we see yellow dots a very small lightning and other space is like black the reason is distance so i think this is clear now a question is how old is space? the answer is approximately 13.8 billions years old. Now we talking about Is earth or space time is same or different so in this theory it is described like one hour of earth is 0.0026second in space its not the exact value but according to the calculation of Einstein theory because it is most relatable reality ok now we are talking about what the smell in space? when some persons are going to moon or other planets they survey space and put down his helmet for testing and these peoples tell the in space is like sweet smelling like burning metals or gun powered or like burning almonds some astronauts very like the smell in space but no one knows where is the smell coming from?


In recent research, scientist discovered Black Hole in space so what is black hole? black hole is a space where gravity pulls so much but light could not enter on it because gravity pulls stars on it and rotate around far from recent place only stars burning light here real light could not pass there but human eye only see this process this is black hole. Black hole is like pipe shape in space where stars and planets are going on its speed but enter in this hole it can rotated in other direction these objects so this is the process of black hole. Now we are talking about black hole parts so first one is inner side and second is outer side lets talk about inner side is like freezing cold and outer side is very hot, if we measure the temperature of outside of black side it is similar to our sun.


Space have no gravity and air every body knows but some scientists experienced that when a heavy thing going to space then what will happen so in past there are two experiments are performed in this world a two big giant rockets are made for going to space see what happen and the fact is the launched directions of rockets is horizontal the first one is X-15 and other one is SpaceShipOne. In 20th century, scientists want to discover that why is space(universe) is so big! The universe is so big because it continuously expending around 14billion years ago if you want to measure the distance of universe if you travel the speed of light but you will not be able to do it because it expend to the speed of light.
