What if you travel with the speed of light |

Описание: Imagine you are traveling the space for one light year and comeback to Earth.

Real concepts: Causality violation, tachyons (hypothetical), spacetime intervals.

What happens if you travel at the speed of light?
Einstein's Theory of Special Relativity explains Time Dilation. At 99% light speed, time slows down for you but speeds up for the rest of the universe. It's not just physics; it's a one-way trip to the future.

In this episode, we break down the Twin Paradox and the terrifying reality of near-light-speed travel.

The science behind this episode is based on real physics:
Einstein’s special relativity shows that nothing with mass can reach or exceed the speed of light because it would require infinite energy. But if an object somehow did go faster, relativity predicts causality would break — meaning effects could happen before their causes. This comes from spacetime geometry: traveling faster than light flips your position outside your light cone, making events appear reversed in time from other observers. This isn’t sci-fi — it’s a direct consequence of the relativity equations. That’s why FTL implies time travel to the past and paradoxes.

This video is grounded in:
1. Special Relativity (Einstein, 1905)
2. Light Cone Structure of Spacetime
3. Lorentz Transformations
4. Causality & Spacelike Intervals
5. Research on tachyons, closed timelike curves, and relativistic paradoxes

The key result:
If you exceed the speed of light, spacetime geometry predicts you would move into regions where your timeline intersects the past — creating the illusion of time running backward.
