📎 AI Summary:
The thread discusses a speculative video involving a tiny grain of sand traveling near the speed of light. The original poster, whoosh, treats it as a hypothetical scenario, while user ussnorway dismisses the idea based on current physics, explaining that such a fast-moving grain would likely pass through objects without detection and that the idea of acceleration at that scale contradicts physical laws. Overall, the conversation appears to be light-hearted and speculative, with a consensus that the scenario is more of a theoretical "what if" rather than plausible reality.

Lol first of all a grain of sand traveling at 90% the speed of light would not be detected and if it collided then the most likely outcome is that it passes right through

The idea that it somehow accelerates is against the current laws of physics

Take it with a grain of salt . Yes. I think it was just a what if kinda video .
