Pellegrino's Pre-emptive Prophylactic, or Planetary Suicide

Wet1 is still too damp...

Heh.

Monitoring is useless, for the reasons I gave. It is way too out-of-date by the time information is available. ANY evidence of technology is sufficient to establish that RM capability is POSSIBLE or PROBABLE within a few decades or a century or so.

Who can afford to take a chance that an alien technosociety will be too nice to blast us away? It is criminally irresponsible to your own species to just hope they won't be so afraid of you that they will blast ASAP. So you must blast ASAP.

Everybody must blast everybody ASAP. It's the only responsible thing to do.

Why you think you are not blasted away yet?

Keep on babbling like that. I start to think your 'name' suits you well.

What a crap.:rolleyes: Bet on it the extraterrestrials have the power to blast you away at any time they want.

With your missiles. How typical. Stereotype, copied thinking of the human race's mentality now a days. Narrow minded and without vision. How do you send these missiles? Again. Same question was mentioned earlier in the thread, in case you forgot about it in your self assureness. Guess you prefer to nuke them all in the same time?

Food for thought? Or do you have to call yourself Brainz1 than?
Because you have to think for that. (by yourself!)

Good luck. Nuke yourself in stead.
 
Read and understand

Read the whole thread, Banshee. The technology to produce a missile that moves at 92% of lightspeed is not much beyond present capabilities. I am just acting as "advocate" here for Pellegrino, Powell, and Asimov's analysis of Alien Behaviour. To keep it simple, anyone can make such missiles. The odds that someone might use them are much greater than zero. If you hope that whoever hears your transmissions is too nice to blast you, you are taking a huge chance of having your own species wiped out. The only responsible thing to do is wipe them out first, if possible.

Q.E.D. :p

P.S. Aren't moderators, especially ones with the gift of alien enlightenment, supposed to be above petty ad hominem remarks? Of course, it must be good for something.

There is something obviously very wrong with the Fermi postulate. Prehaps your answer is correct. Prehaps not.

To produce a missile that moves at near light speed requires more energy than we can yet produce, no matter how wishful our thinking on the subject. To have it zero in on a target by spirling in requires that same missile to tote yet more mass to be moved at relitivistic speeds, mass that is needed to supply thrust force to get the missile up to speed. It boils down to we can not do that yet, no matter what our intentions.

In the long haul we might be better served to spread out as suggested before. First to the solar system and then to neighboring star systems. Of course another thing that we can not do yet.

I understand where you are coming from. I understand your postulate. What I am saying is that at present even if we recognise the danger there is nothing we can do about it now. Until the capabilities are there all we can do is run thought experiments such as this through the mill.
 
I agree

Sort of. But read the novel; it's a fun read, and the technology explained in it is real, and only slightly ahead of our time (like Pioneer;) ). It ain't so hard to do.

Human technology is just developing right now. Just over the last 50 - 60 years, the humans have done such inventions and tried to 'copy' the thechnology of the Spacecrafts they hide in secret, for the rest of the world. Can't care less about Pellegrino. All theories. I gave you the post by SETI because of its mentioning how far the distance is to reach the extraterrestrials and how long it may take to really get a response. (the way humans want to.)

How do you know there is no contact with extraterrestials? Are you really sure about that? You think the extraterrestrials come to your doorstep and say 'Hi, we are here'?

And the human race doesn't need inerfention from the extraterrestrials to wipe them out completely. They are doing quite well in destroying the world and Her inhabitants right now.

Open your eyes for the world in stead of making crazy ideas to get to the extraterrestrials. It won't happen. Not in your life time.

The extraterrestrials come to Earth, not we to them in certain missiles which never will have the power to reach them.

I'll leave it with this. Have fun with your 'flaming' and try to open your eyes. There is a lot going on at the moment. On Earth as well as in the Universe(s).

Goodbye...:)
 
A few points and some questions.

1. Even if we can produce a missile that has velocities approaching the speed of light, we would have a very difficult time at guiding it to its target over the distance of many light years when that target was a planet. Course or trajectory changes would have to happen incredibly fast and we would have to have some incredibly good information on the gravitational dynamics of the solar system we were aiming at in order to even begin to calculate appropriate trajectories for our missile. How do we get that information from just a radio signal?

2. Detecting a radio signal and then localizing its point of transmission to a solar system, let alone a planet, over vast distances of space is an incredibly difficult task with today's or even the next 20 years technology. How does this civilization do so unless they have already expanded out into the universe and can somehow triangulate or trilaterate our signal?

3. If this civilization has expanded out into the universe, what type of technology are they using to communicate between planets in order to coordinate their search and destroy mission?

4. Unless we assume some type of faster than light capability, how is their civilization keeping track of all of its own colonies so that it doesn't accidently kill one of its own?

5. Is it reasonable to assume that the development of technology by any species would mandate the same type of transmission we use? If Marconi had taken a different direction and moved towards impulsive radio systems that are just now being developed here in the US, then the types of radio systems that we have traditionally used would never have been invented or used and the receivers that would have been developed would not be capable of receiving our types of radio transmissions. If an alien race had taken the impulsive radio path, then they would not be able to detect our radio transmissions with their receivers.
 
Questions

Fair comment.

1) Locating and specifying orbit, etc., is much easier than you think. A radio emitting planet would be a very clear, distinct point source. Computing orbits is well within the capacity of even a simple computer. The missile would have a receiver/sensor which would give it plenty of input and time for course adjustments...planetary orbits are very stable. Remember, it would take about 6-12 months to get up to cruising speed.

2) See above. Given a few days or weeks of observation, it is easy. SETI astronomers would go apeshit delerious happy to have that much data (so far they have none). Because radio and other artificial EM signals are at unique frequencies, such a planet would be brighter than any star at those frequencies.

3) The timing of this is hard to specify, but local space capacity is enough...a missile is a very simple device compared to a full spacecraft.
The book, Flying to Valhalla, makes the point that paranoid hostility between mother and colony planets would be VERY hard to avoid. Don't expect to see many surviving colonies or mother planets.

4) Slowly, with great difficulty, fearfully, anxiously.

5) Marconi's path was unworkable...very low data rate, etc. (Voice radio was invented by Canadian Reginald Fessenden in 1900, and his system is what we use.) Anyway, EM is EM. Radio telescopes can be tuned to receive any frequencies. SETI scanners cover millions of "channels" at once, e.g.

But this is filled with flaws...

Your assuming that an alien form of "life" would be capable of thought, let alone humanoid thought. You assume that an alien life form(s) would be nearly identical to us, existing in multiples, reproducing, colonizing, etc...

Your also assuming that an alien "civilization" would use even close to the same line of technology we have. Perhaps instead of physical workings an alien technology had more use for raw sunlight than metal.

The chances of life in the universe being almost exact to us in function is minimal, but there is definitely life, just not functioning in a social system of multiple beings that work individually.

Put yourself in a being's position that is non human. You don't know anything about humanity, or its culture. Immediately you get some messages from them on radio band or from the probes... why would your first instinct be to blast the hell out of it? There is much more useful ways to treat an unknown civilization than to annihilate it.

And for the record, extra-dimensional travel (fourth dimensionally, instead of surface 3d travel) would be much faster than C :)
