Few days back when i woke up i experienced that my head was spinning vigoresly.
I caught hold of my bed I thought i am travelling through a wormhole. Now i will land in another dimention...i had read...
I screamed my family came to help. I landed at doctors clinic, he pronounced that it was cervical spondylosis. I thanked almighty that i got well. My mind was thinking of the wormholes, time travel the dimentions.....
WHAT IS TIME?
In physics, time is described as a dimention much like length, width, and height.When you travel from your house to the grocery store, you are travelling through a direction in space, making headway in the spatial dimention -length width and height. But you are also travelling forward in time, the fourth dimention.(Sara Goudarzi)
What does a dimention mean?
A dimention is a degree of freedom of a system. In simple words it is a numberof ways or direction in which change can take place in a system. we can understand by the following example.
Imagine an ant walking on a thread. It can move forward and backward only.It cannot move side ways That means its degree of freedom of movement is in one dimention only. Now imagine that ant is placed on a flat surface. It can move forward sideways but not upwards or downwards. That means its degree of freedom of movement is two dimention. Now imagine an ant has wings . Its degree of freedom of movement is upwards downwards sideways forward and backwards. Therefore its degree of freedom of movement is three dimention like us.
Bob Singer NASA Engineer says , an object that actually exits from the time it came into existantance until it ceases to exist has a duration the fourth dimention.
That means the ant that was moving on the thread had not one but two dimention one was space and the other time. In the same way we live in this world in three dimentions plus one time dimention.
Special relativity propounded by Einstein demolished the concept
of absolute time. He unified time and space terming spacetime
He termed it as our fourth dimention. In space we can move forward and backwards but dimention of space time we can move in
one direction that is forward only. the concept of time dilation in special relativity t ells us that time slows down for an object as it speeds up to the speed of light. For example, a person A who is travelling in space with a speed of light, and a person B who is stationary B on Earth, the person A who returns to Earth say after five years in space sees that the person B on Earth has aged in decades. The faster you move the slower time changes for you! It is a fact which has been verified through experiments.
Time is unique dimention you can move in one direction that is forward you cannot move backward.
Can we Time Travel?
Time Travel has been mans wildest fantasies for centuries..
H. G Wells "The Time Machine" and the latest fiction movie "INTERSTELLAR"
Intersteller is a science fiction the film is directed by Chritopher Nolan the film features a crew of astronauts who travel through a wormhole in search of a new home for humanity.
(Matthew McConaughey and Anne Hathaway star as Joseph "Coop" Cooper and Dr. Amelia Brand respectively.)
According to Einstein's theory of general relativity, a wormhole could act like a bridge though space-time by connecting two distant points with a shortcut the Einstein Rosen bride in 1935.
In the late 1980s, Thorne said that a wormhole could be made into a time machine.
