So at relativistic velocities, any ship will have. Therefore they. cannot avoid being caught. My gut level feeling is that neither of my acquaintances. V, size of weapons footprint, etc. Any thoughts JWMeritt. My thought Sounds like the scenario in Nivens Ethics of Madness short story. In your scenario much depends on. Erik Max Francis. I think the answer really comes down to the actual maneuverability. Mike Williams. I reckon that for relativistic velocities to be practical in your. Bussard ramjet, then they should be capable of sustained accelerations. If they cant do that, then its going to take them. I dont consider very. The first ramjet starts to thrust sideways at a constant 0. The second ship cant possibly observe which way. Thats only 0. 0. The second ship cant guarantee to come closer than about 5 light days. The Outrider was a heavily modified YT2400 light freighter used by the brash smuggler Dash. Collection Item Summary This model of the fictional starship Enterprise was used in the weekly hourlong Star Trek TV show NBCTV, which aired from September. Hop David. The light year separation is observed from whose frame What. Nyrath. I dunno, this exceeds my meager knowledge of. The key factor seems to be relative velocity, that is. Hop David. By what relativistic velocity I meant whaf fraction of c. I believe. observers on both ships would see an approach of the same velocity as. If they are going a very good clip, the spatial distance could also be. One observers lightyear. Serg. As far as I remember from huge Relativistic Kill Vehicles RKVplanet killers thread its more or. Nyrath. Oh, I agree that if the target is a planet. However, is that true if the target is capable of. And is it true if the targets performance is. Serg target propulsion the same Target evades if it far enough from interceptor and have comparable fuel resource. In this case target evades without any doubt. Isaac Kuo. Actually, I calculated that a dumb brute force approach works. The dumb brute force approach is to throw a planet sized wall in. This wall is actually a puff. This really really really thin spread wall looks like a dense. It vaporizes the munitions instantly upon impact. To a rough approximation, the amount of gaseous material the. The fact that this mass is. Assuming the defenders have anything vaguely like the capabilities. However, is that true if the target is capable of. Umm. Serg is saying the opposite of what I think you think hes. Hes saying that our conclusion was that a near c interceptor. In other. words, a near c attacker could not intercept a near c target. I think youre going an extra unnecessary step, thinking that. This is true. but its. Basically, its the defenders game either way. I havent thought of a way to make near c weaponry workable. They just give too much free energy to the defender to. Roughly, you stick to a munition velocity low enough so you. Brian Mc. Guinness. So instead of a missile you now have a gas with nearly the same momentum. Why is this an improvementIsaac Kuo. Because it isnt nearly the same momentum and energy nor is it. When the small mass of the incoming near c munition hits the much. Actually, when it first hits the closest. However, this defense cloud is many planet diameters deepthe cone. Very little of this explosion will impact the planet, depending upon. For example. if this defense cloud is being thrown from near the planet itself. About 1 of the explosion would. With more sophisticated plasma thrusters, the. Timothy Little When the small mass of the incoming near c munition hits the much. This does not at all square with your previous assertion that the. Furthermore, you are forgetting that relativistic collisions should be. Using your generous figures of say 2 Gm interception distance, an. RKVs with an. assumed mass of say 1. Ill. assume the defenders have the same energy budget and 1. The cloud is say 2. Mm wide enough to shield the planet, and 1. Mm. deep many planet diameters. The cross sectional density is thus 3. To model the interaction, it is best to consider the RKV to. With this area density and these energies, the. RKV and cloud nuclei is. Hence 9. 9. 7 of the RKV nuclei are affected only by mere chemical. V per nucleon to give a gross overestimate. This imparts an average deflection of up to 4. Hence. with even 4 days to prepare, and the same energy availability as the. RKV from hitting the planet. With less time, quadratically more energy would be required to get the. Furthermore, it is likely that the defenders. Hence, I conclude that for a 0. RKV, the defender needs at least. Isaac Kuo This does not at allsquare with your previous assertion that the. Thats the minimum amount of mass required to obliterate the incoming. In reality, the defenders can afford to put up many orders. I stated in the first posting. Furthermore, you are forgetting that relativistic collisions should be. Using your generous figures of say 2 Gm interception distance, an. Very dense disk is a relative term. Something a hundred kilometers. What launch mechanism do you have in mind with which to acheive. More or less, there are only three possibilities A honking huge particle accelerator. This one wont work because. An antimatter rocket. This can work, but the pathetically low. This gives the defenders a very very. Also, the minimum resources. Laser sail. This can work, with reasonably high accelerations. With the sail travelling away from the beam, the. The final. hours or weeks of acceleration is provided by the beam generated. Whats worse. this beam is severely red shifted, reducing its effectiveness. The effect is bad enough at 0. I could see it going up to 0. Note that whatever acceleration mechanism you use, it MUST accelerate. If the munitions accept even. AU conical beam. by the time it reaches the target system. Realistically, the only plausible way to deal with this problem is. For interstellar laser sails, the. Realistically, even 1. If youve got a laser powerful enough to go the interstellar distances. Unlike the sail weapon. NO preperation timeno brightly visible. Ill. assume the defenders have the same energy budget and 1. What munition mass do you assume What velocity of the defending. When calculating the energy budget, did you consider the inefficiencies. Did you consider. For example, laser launch. In contrast, the defenders can use existing rockets and their rocket. At the. low exhaust velocities ideal for interplanetary uses, rocket nozzles. OTOH, energy. budget is not the limiting factor. Mass budget is. Timothy Little Very dense disk is a relative term. Something a hundred kilometers. It is the latter case that you were proposing for the defending cloud. I was basing my estimate of the speed on your post. To make the. 5. 0Mm deep cloud look like a disc, you need a gamma of about 2. What launch mechanism do you have in mind with which to acheive. I dont think it is feasible at all. I was simply countering your. If youve got a laser powerful enough to go the interstellar distances. I fully agree. I wasnt proposing that RKVs are useful weapons, just. You need to intercept them with a few tonnes. Note this is just as true for 0.
