Variables in the Universe
Posted by Srinivas on May 6, 2008
There are number of variables affecting a single result in the universe. The result which considers everything would be a perfect result. Such a result would never fail. If you make a prediction with such a result, it definitely shows up in reality.
We are saying that certain planet comes at certain distance to earth at a particular time in a week etc. But these are not accurate. The planet may miss the prediction by some 20 minutes difference. So, the variables we are taking in to consideration are very limited to predict even the smallest things like velocity=distance/time. Every time we write an equation, the variable taken is approximate by at least a micro or nano times. Apart from this, we neglect some thousands of more variables which affect the result.
For example, consider the time of descent of a freely falling body. The result is dependent on the gravitation of earth. If sun could attract Pluto from such a great distance, wont it affect the freely falling body on earth? We neglected it because it is very minute. These minute negligible variables of large number would change the entire result of may be some other equation.
Mass, Length, Time, Temperature, Pressure, etc. are these alone the dimensions controlling the whole universe? There may be some thousand more dimensions can’t it be?
One day when all the variables in the universe are known, and there exists a electronic device to take all such variables in the universe and gives the output, future is predictable. You need to give the inputs from the present, the output shows the universe in front of your eyes. If such a sitation really arises, then it would prove that future cannot be changed.
“Future cannot be changed” seems something odd. But if the past cannot be changed, and the present is the product of past, how come future can be changed, which is the product of past and present?
