 Source: space.com (click the link to read the information) What do you think of it? Personally, I think this is going to be very interesting. For reference, Chelyabinsk meteor's released energy was 400-500 kt of TNT. |

I think that could be a bad idea, even though the planets are unlikely to have aliens, what if they do? Or what aliens have set up infrastructure there? The aliens could get very pissed.

Oh, that's an interesting thought. It's interesting to think that way, but these impacts are probably not very destructive. I'm afraid it could be some 'threatening sign' for an unlikely team of hypothetical alien colonists though. |

NO 1 gram is too small for a star probe... something like 10 ton may be more reasonable...

The whole concept of Breakthrough Starshot appears flawed to me, as collision with interstellar gas and the occasional grain of dust would probably destroy the probe long before arriving anywhere.
Also, there is something to be said against loud, highly visible actions that would be visible at high interstellar distances until we make sure the reason to the Great Silence is not something lurking in said interstellar distances. Like, say, an alien force making sure to cull anyone capable of deploying interstellar ballistic missiles before they grow out of control.
Then again, if there is one thing I learned from observing hardcore METI proponents is that Flat Earthers shouldn't feel too bad, they're in good company at least.
(If you aren't sure about how stupid METI as an idea is, watch Battleships. This film is a monument of stupidity, and its foundation is METI in the first place.)

Check it out. And I just don't think the one gran probe with a such small sail can withstand the thermal energy from the laser.

There are researches into self-healing chips for travels, and when you shoot these you'll be launching hundreds or even thousands of them toward a single target. Check it out. And I just don't think the one gran probe with a such small sail can withstand the thermal energy from the laser. I don't really know thing, but since this is supposed to be a discussion about whether should we slam some of them into it, go wash your face. |

Any species with the kind of tech and resources capable of steamrolling other civilisations is perfectly capable of detecting any civilisation sending out radio waves and having lights at night. This kind of power implies a vast industry, capable of waging interstellar war. Such industry means sending observation craft to all nearby stars is a negligible expense. Hiding is pointless. If you think there is a reasonable chance there are genocidal aliens nearby, the superior strategy is to go loud (to possibly attract the attention of multiple civilisations) and expand as rapidly as possible. A K1-almost K2 is a whole lot harder to take down than a <K1, especially if interstellar colonies are involved. |

'Expand as rapidly as possible' I hope this could become reality by few hundred years... How about a forum based interstellar war game |

There are researches into self-healing chips for travels, and when you shoot these you'll be launching hundreds or even thousands of them toward a single target. I did, and for what I could gather there is simply no way for such a low cross-section density object to survive fast interstellar travel. To survive it, you need mass per square metre and BS has almost none. ...

A K1-almost K2 is a whole lot harder to take down than a <K1, especially if interstellar colonies are involved. Giving that we know precisely nothing about the capabilities of a distant mature alien civilisation, affirming that they can detect us (and are actively searching for it in the first place) is a bit preposterous. Oh the other hand, we should also assume at least some can and plan accordingly. Now, assuming they detected us, showing ourselves as trigger-happy interstellar bombers throwing relativistic projectiles against random planets may not be the best way to convince them to not divert a (potentially trivial) amount of resources to wipe us out of the starmap. Even throwing high-powered lasers in an attempt to say hello may make the difference between "don't care" and "bothering me", with potentially deadly consequences, and METI should be dealt with accordingly. Note that I think the most probable answer to the Great Silence is that we are one of the very first potentially interstellar forces to emerge in this corner of the Universe (far older ones may fill countless other corners, but they are too far to be a factor). As such, there would probably be no such consequences of doing stupid like that, apart from potentially wrecking bits of planets that could be useful later. However, that's like finding a random syringe that is clearly " probably harmless" - even so, injecting yourself with it just because bad consequences are a low probability would be very, very stupid. |

I have no idea about this, but personally I am not quite a fan of the word 'impossible', barring 'physicists' level o' impossible'. |

A different answer to the Great Slience is a metaphor, a savage in a jungle is listening for drum beats of communication, oblivious to the radio waves screaming by overhead. Substuide savage for SETI and radiowaves for something we can't detect and you get what I'm aiming for
