TIME- Its origin and fate
Today we all know the importance of time but how and when the time originated. lets have a look at the brief history of time.
Origination of time
According to scientists time began with the big bang- a leading theory behind the formation of our universe. Astronomers believe that universe began with big bang because they have found plenty of evidence about this theory like they had failed to found any cosmic object older than the age of universe and also the universe is expanding this mean that it has started from some where . lets have a look at how it began.
1.Before big bang there exists nothing, no even the time was existing . In this nothingness there only existed a hot red spot containing the raw ingredients of our universe scrunched into a point smaller than the size of an atom called as singularity.
2.Then this hot red spot get doubled in size- and get doubled again- at least 90 times in the process called inflation. This was the "bang" in big bang.
3. Now universe began to expand at speed of light marked with beginning of time.
Time is considered as unidirectional, it is moving in the direction of expansion of universe. we are also moving forward in time with the rate of one second for every second. now a question must be arising in your mind that - can we do time travel? It can be explained with the theory of time dilation. now lets understand time dilation.
As I had mentioned above that time is moving with the expansion of universe and we are moving forward in time at rate of one second for every second but as we speed up the time slows down. you can understand with his example- imagine a train moving at 99% of speed of light and a boy start running inside the train on observing this system the boy will appear to travel faster then the light. Similarly time is moving at a certain speed if we travel at any speed it will appear that we are travelling faster than time. This situation is known as time dilation although when we move, there is a time dilation but it is noticeable when we travel at speed of light.
Is there is place where time has stopped?
yes as we know if we travel at speed of light we can experience time dilation this means that time is affected by light and light as we know is affected by gravity so we can also say that time is also affected by gravity. The bigger mass of planet will be , the higher will be its gravitational force and higher the gravitational force will be the speed of time will be slowed by that force. This means that where the gravitational force will be very very high like in black holes from where even the light cannot escape, there the time must eventually had been stopped.
What will happen if universe will stop expanding?
The answer is that the time would also stop. but it is impossible as i have mention in my previous blog that actually it is speeding up due to dark energy. But imagine if time would stop we will become immortal. But it will only for a certain time if universe will stop expanding then due to its own gravitational force it will start contracting and then we will travel back in time. weird! yes and it will contract back ultimately to singularity and time will again run out of existence.
