| Jul 7, 2022 at 20:34 | comment | added | Nosajimiki | @JustinThymetheSecond I simply refer to how it will pass though vs colliding with matter. The faster a relativistic collisions happens, the farther matter has a chance to pernitrate before colliding with the matter of the thing it is running into. Beta radiation and Alpha radiation are both matter. Alpha radiation pernitrates less than Beta radiation because it is slower allowing electromagnetic forces more time to steer it into a collision. 0.9C is faster than Beta radiation so it will by virtue of probability pass between more atoms before colliding with one. | |
| Jul 7, 2022 at 11:39 | comment | added | Justin Thyme the Second | @Nosajimiki That does not make sense. According to relativity, that particle traveling at 0.9c has absolutely no idea it is traveling at 0.9c, and therefore would NOT be anything like you say, it would just be a normal particle. That is the paradox in relativity. A particle traveling away from you at 0.9c means you are traveling away from it at 0.9c. Does that make YOU 'something between Beta and Gamma radiation too? | |

At 0.9C, this micrometeor will not so much act like solid matter, but more like something in between Beta and Gamma radiation. Even if we assume Gamma Radiation's higher rate of penetration, about 99% of that energy will be absorbed by just 1/2 a meter of water which means you will have a more or less surface level thermal explosion powerful enough to blast a massive crater into your ice, and any ship within it. | |

| Jul 2, 2022 at 19:18 | comment | added | DWKraus | @JustinThymetheSecond I think we aren't speaking the same code. If the particle goes straight through the shielding (and assumedly the ship on the other side) the ship still has a small hole punched straight through it. No net improvement on safety. Unless you are envisioning the high velocity particle being fast enough to make a tiny hole without shielding, and slowed down enough by the shielding that it sheds its remaining energy in the ship rather than passing through? | |
| Jul 2, 2022 at 17:15 | comment | added | Justin Thyme the Second | @DWKraus Would you prefer a few people die then the entire ship going up in explosive decompression? Generation ships will not be heavily shielded, but everything will be made multiply redundant. | |
| Jul 2, 2022 at 14:45 | comment | added | DWKraus | @JustinThymetheSecond Since it's shielding, going through doesn't help much with safety, regardless. | |
| Jul 2, 2022 at 2:26 | comment | added | Justin Thyme the Second | All of that energy is 'released' only if the particle STOPS. If it goes right through the ice and out the other side, only a fraction of the energy is 'released'. | |
