Physics.......

In classical physics the future is just a half of the timeline. In special relativity the future is considered as absolute future or the future light cone. In physics, time is considered to be a fourth dimension. Physicists argue that space-time can be understood as a sort of stretchy fabric that can bend due to forces such as gravity. While a person can move backwards or forwards in the three spatial dimensions, many physicists argue you are only able to move forward in time.[8]

The physicist who advised the makers of the fictional time-travel film Déjà Vu claims that a person could hypothetically travel into the future if they had a spaceship that could travel at almost the speed of light. After a voyage on this ship, if a person returned to Earth, millions of years would have passed in Earth time.[8] Some physicists claim that by using a wormhole to connect two regions of space-time a person could theoretically travel in time. Physicist Michio Kaku points out that to power this hypothetical time machine and "punch a hole into the fabric of space-time", it would require the energy of a star. Another theory is that a person could travel in time with cosmic strings.

Similarly for mathematics, at least in a sort of comical theory, trying to comprehend and predict the future might be possible if one were to derive the most complex mathematical equation that could ever exist pertaining to the exact flow and location of every bit of matter and energy within the universe.[citation needed] Put simply, a progressive equation of every aspect of everything known to exist.[citation needed] However, if it were possible to do so it would likely take an infinite amount of time to perform the tedious calculation and therefore prove to be futile.[citation needed]
