Abstract

This paper explores a new paradox in special relativity, examining implications for our understanding of the universe’s age. The paradox involves a spaceship traveling towards a planet; light signals are exchanged when they are 10 light-years apart. The signals meet after 5 years from the planet’s perspective, but the distance from the spaceship to the meeting point is less than 5 light-years. A solution exists which will prompt a re-evaluation of Einstein’s demonstration of non-simultaneity. The planet’s perspective shows the meeting point at 5 light-years, while the spaceship’s perspective indicates a shorter distance due to its motion. The solution tells us that both perspectives are valid within special relativity. But that leads to two possible ages for the universe. Those two possible ages question the validity of our measurements, and the validity of the current universe’s age, suggesting that the current framework may need refinement before a final result can be given.
