HOW FAR CAN YOU MOVE WITH THE PASSAGE OF TIME

  

Is there any kind of limit of humanity.Let`s imag
ine about it. . 

We all like to travel to a place which gives us pleasure.Most of the people travel various places in their entire life, for someone it become her/his hobby.But how many of you imagine about interstellar trip.There may be some kind of limitation for us in case of interstellar trip.  

                     We all know there are most of places of an atom remain empty.So in very small scale we can say that there are very long distance in between elementary particle also. Similar way there are various planet are various thousand miles away from each other.

                     We all know that due to the some certain energy our universe goes on expanding. due to this reason our space time goes on expanding. we all know that there are four fundamental forces  in nature, there are - Gravitational force, Electromagnetic force,Strong nuclear force, Weak nuclear force. Among this forces the gravitational force are known as the oldest force of nature in respect to the big bang.After the big bang the gravitational force dominant in some region due to which reason our solar system or we can say the galaxy is exit at that moment.But in the other region the unknown force show it`s dominant . So as a result there are million of light years of distance between two galaxies. Andromeda galaxy is the nearest galaxy of the milky way galaxy which is almost 2.5 million light years away.As the expansion rate of the universe goes on accelerate so one day it may be cross the speed of light , so at that moment we cannot see any stars of our neighborhood galaxies . As gravity dominant in our galaxies so it is not effect the distance between planets of our galaxy to much.

                      Imagine at that moment scientist made a very high tech space ship and want to travel to our neighborhood galaxy but can we do that . No we cannot because at that moment when we leave our galaxy we are out of the gravitational interaction of our planet and enter the region in between galaxy where the unknown energy dominant . As we cannot move faster than the speed of light but as the expansion rate is faster than the light so we trapped in a region and cannot move to our destination. At that moment if we want to move to our own galaxy we cannot do it also .

                     

                        Now think that the speed of our space ship is infinite and also the expansion rate is infinite . At that moment if we are in the region in between two galaxy where gravity is weak than what will happen?(∞ -∞ =∞ remember this )
