In Science-Fiction, time travel is a well-known concept. The ‘Back To The Future’ trilogy (IMDb, Wiki) probably still rings a bell with many people. In theoretical science, time travel is indeed possible into two directions: the past and the future. In practical science, however, time travel is only in one direction: forward – into the future. The Economist of 5 September 2015 features another scientific mystery: why is travelling through time, unlike travelling through space, irreversible?
The simplest way to travel to the future is to accelerate away from Earth in a spaceship, and then turn around and come back. Some of Einstein’s equations describe the relationship between the time experienced by two bodies, one of which is accelerating while the other is not. They show it passes more slowly on the accelerating body. If a craft made what was, from its crew’s point of view, a 40-year journey away from Earth at a steady acceleration of 1g (speeding up for the first half of the outward leg, then slowing down, again at 1g, to reach the turning point before repeating the procedure for the return leg), that crew would find on their return that 58,000 years had passed on Earth. Such a journey to the future would be a one-way trip. A more fantastical machine might, however, be able to manage a trip to the past as well—though the time-traveller could not go further back than the date of the time machine’s creation. (Economist)
Although theoretical science essentially allows for time travel to the past, it seems to scientists that the “Laws of Nature” would prevent this (Economist video). In essence this would – and should – then also imply that these same scientific theories would be flawed, incomplete, imperfect.
Time travel to the past would open the door for humans to change / rewrite history. Given human nature such changes would have (ulterior) motives which would most likely relate to the 7 Belief systems: Love, Money, Philosophy, Politics, Religion, Science, and the Truth. In essence, humans would want to create an Act of God in their own – selfish – benefit. Moreover, the resulting chaos would even prevent something that we now call “history”. There is no history when history becomes a variable – rather than a constant.
Time is not very relevant when there is no agenda, no appointments, no meetings – or in other words: no planning. Without time to worry about then eating, drinking, sleeping is what really matters – or in other words: survival. The human concept of time is only some 4,000 years old (see my March 23 blog) while humanity itself is some 2.5 millions years old (see my April 26 blog).
No other species on Earth is so much concerned with its age than mankind. In fact, we are the only species having birthdays and an official – legal – age. We spend lots of money on tools that enhance the optical illusion of our age towards other humans (e.g., cosmetics). Time travel would just be another tool in our eternal quest for immortality.
According to the Bible (Genesis 1-26), mankind has been created in God’s “image” and “likeness.” That image now tries to become the Original. The “Laws of Nature” – or any other more religious kind of name – would most certainly prevent that from happening. An image is stored in the picture book of Time. An image does not become the Original – or Time itself.
