The Twins Paradox

Making reference to Special Relativity, which in simplified terms here says: Your clocks will tick slower the faster you travel, relative to a stationary clock say, on Earth. This 'slowing' is understood to include all experiences relating to the passage of time, such as motion, our metabolism or any other chemical reactions; so humans on board a speeding rocket would not feel anything unusual about themselves, their activities or their surroundings.

The people involved in this experiment are famously called Twins A and B. The classic view is that, while Twin A remains on Earth, Twin B travels in a rocket at near light speed towards a Stellar system 4.5 light years away, called Alpha Centauri. He will then pass around the system and return to Earth, a journey that should take him about 10 years. On his return, his brother is understandably 10 years older, but remarkably Twin B has only aged a few months.

However, in this short essay below, the events that unfold and their enlightened conclusions are somewhat different.

1. Twin B sets off in his spaceship, prepared for a long, ten year voyage.

2. Twin A remains on Earth during his brother's absence, not expecting to see him for years to come.

3. Surprisingly, Twin B returns after just 6 months. Twin A is baffled and considers that his brother did not complete the journey as they had planned, that he must have turned back early having become frightened or confused.

4. Twin B disputes this and remarks that he has travelled a distance of a little over 9 light years, so to have returned in only six months as measured by Twin A's clock, means he must have well exceed the speed of light.

5. Twin A agrees with his Twin that he was only away 6 months, but states that the speed of light cannot be surpassed, so he could not have travelled the complete distance, he must have altered course.

6. Twin B then exclaims that, in deed he did. Something remarkable happened while he was on his pre-programmed journey. He noticed that the Earth began to slow down behind him once he reached relativistic speed.

7. Twin A is bemused and asserts that this could not be the case, as he was on Earth the whole time and nothing strange like that took place, he would have known.

8. Twin B agrees, but says that on looking towards Alpha Centauri he noticed the same thing, that the system also appeared to be slowing down, and that he was not going to intersect with it on the current trajectory.

10. Twin B persists: "So, I re-set my course several times to intersect my lagging destination."

11. "Oh," Twin A exclaims. "And, how long did it then take you to reach Alpha Centauri?"

12. Twin B tells his twin that it merely took him about 3 months, as they had assumed it would from his perspective. Then on returning he did the same thing, re-calculating the intersection with Earth, the back journey taking another 3 months.

13. Twin A pauses and then remarks that perhaps it is motion through Time that is the relevant factor here, and not motion through space.

14. "How so," asks Twin B?

15. "Well," says Twin A, "What if, as you and your clock slowed down, you were somehow slipping back slightly in time behind everyone else and could only see other things around you that were in the same moment you were in."

16. Twin B is struck by a thought: That would explain why the Earth appeared to slow down, as he would be seeing behind where it actually was.

17. Twin A agrees and then states that he must therefore not be the same Twin A that his brother had left on Earth, because that facsimile of himself would now be many years in the future.

18. "But you are aware of me now, so that would mean we are conscious in all moments, throughout time." exclaims Twin B, then adding that such a scenario would mean that all of time, from the past and on into the future, would all already be in existence, and at the same time.

19. Twin A agrees and remarks that had his brother stayed on course and not re-calculated his return trajectory, he would have passed through the intersect point with Earth in about nine years time and not seen his home planet anywhere.

20. Twin be is shocked, but thankful, and wonders, how it could be that he is conscious in all moments simultaneously, but is only aware of now..? While Twin A is pondering how it could be possible that we can travel faster than light if we arrest our progress through time... When all of a sudden it hits him!

Special Relativity assumes that there is a constant universal clock that makes us all aware at the same moment, regardless of our clock speeds; it does not take into consideration that all of time and all moments already exist, so it fights to contain reality in an unreal World by suggesting there is such a thing as motion - when there is not, there is only progress through time.

Next: The Grandfather Paradox a sci-fi fabrication?

Time's Paradigm is a philosophy of science paper discussing the reality of time. It argues that time is a cyclical fourth dimension, where zero and light speed are attributes of the same event and infinite progression is invalid.
