How would a spacecraft traveling near light speed avoid a (relatively dense group of) asteroids? Or suppose such spacecraft is designed, how would the physics work for steering it inside such a "cloud" of asteroids?
If it simply by designing the spacecraft to have huge acceleration, wouldn't th...
IMO, it isn't that good a question, but its core "what are the dangers for a very fast space ship ,ad how can we fix it" is an OK and on topic question
@CrazyBuddy ah. Try to leave comments next time you're sure a q should be close :)
See, as the site grows, we mods should have to do less direct commenting/closing and more flag handling
Hi user. Welcome to Physics.SE. This question seems highly imaginary to me. Your quote: "Suppose a spacecraft is designed" - looks like a sci-fi to me... Because - I strongly argue that, "If that would happen, Then all other constraints would also be solved..." Please have in mind that we're HUMANS. Think it this way - We try to launch space vehicles. We'll think of every necessary step to do that. If we were to launch the near $c$ speeding vehicle, before that - we'll solve the question: "What about celestial object impacts?"... — Crazy Buddy1 min ago
If we have an ideal gas which goes from $(V_1,T_1)\to(V_2,T_2)$, we can derive $\Delta S_{12}=nC_v\ln\left(\frac{T_2}{T_1}\right)+nR\ln\left(\frac{V_2}{V_1}\right)$. As $T_2\to 0$ and $V_2\to 0$ $\Delta S_{12}\to-\infty$, can someone help me see how this goes wrong

@Manishearth from now on, I will associate all deans of student affairs with delicious south Indian cuisine :)
