Yes, under the laws of physics, a bomb traveling in a circle around the Earth at faster-than-light (FTL) speeds would result in a causality paradox, meaning it could theoretically hit itself or its own launch vehicle before it was even fired.

Question was if the bomb was shot off faster than the speed of light, around the earth: Would it hit itself...
💥

If I shot it upwards, would gravity destroy it.

No, gravity would not blow up the bomb.Instead, two other physical phenomena would prevent this from happening: Einstein’s Special Relativity (which forbids the bomb from reaching or exceeding the speed of light) [cite:1.2.9] and atmospheric destruction (if it were actually shot into the sky at near-light speeds) [cite:1.1.7].Here is how physics resolves the scenario:1. You Cannot Reach Faster-Than-Light (FTL) SpeedsAccording to the Special Theory of Relativity, any object that has mass can never reach or exceed the speed of light [cite:1.1.15]. As a massive object accelerates, its kinetic energy increases exponentially [cite:1.1.3]. To reach the speed of light, an infinite amount of energy would be required [cite:1.1.3].2. The Atmosphere Would Vaporize ItIf you somehow managed to apply enough energy to fire an explosive towards the sky at a massive fraction of the speed of light, it wouldn't be gravity that blows it up—it would be the air [cite:1.1.7]. At that extreme velocity, the bomb would violently collide with air molecules (like nitrogen and oxygen), generating a massive cascade of radiation, heat, and plasma [cite:1.1.7]. The bomb would physically disintegrate long before the word "explosion" could even be fully processed [cite:1.1.7].3. Gravity's Actual EffectGravity pulls everything downward and does not cause a bomb to detonate on its own [cite:1.3.8]. If you fired a massive projectile at relativistic speeds in the perfect vacuum of space where gravity is present, gravity would only bend or curve the bomb's trajectory [cite:1.1.15]. If it passed near a massive object like a star, it would act like a slingshot, altering its path rather than triggering an explosive device [cite:1.1.15].Could you tell me what specific hypothetical scenario or science-fiction concept you are thinking of (e.g., a warp drive, a particle beam, or an impact weapon)?I can help explore how the laws of physics would treat that specific idea!Would a bullet travel faster than the speed of light? - FacebookJul 5, 2018 — Einstein once called the speed of light “The Universe's speed limit”.
