You definitely have to hold your position for a while. This is not a cheap occupation, eve-dropping on the mob-boss is not easy, eve-dropping on a boss 200 light years away is not expected to be easy either. There is a base assumption that they use radiotelescopes, but if laser projectivity can be refined in the very low wavelength, it might be even cheaper to communicate with lasers in which case you have to really be focused in front of the target to detect. I can see the electronics evolving quickly toward this. And, what if we can tweek the entanglement's no-communication rule such that it allows communication under limited circumstances, if that were the case, at some point all space communications would go silent, forever. As such, we would need to look for passive evidence of sentient life, such as trails of ion-drives, or chemical ejecta, etc. I think this is going to happen, under stringent causality rules its not possible, but it may be possible to do without breaking causality. In addition to that, as computers increase, we may have very little to say to spacecraft, they may be intelligent enough to perform all their standard missions without interference up to the point mission is complete and new parameters need to be submitted.

Its interference between clouds and light reflecting off the ocean, along with a bit of coal/smoke particulates that interfere at high altitudes. Has anyone ever been right close to a thunderstorm and everything suddenly turns a greyish green, weird effects of light can be produced under the right circumstances. Its just waves and atmospheric interference.

We if we could find planet nine, at least in part of its orbit its moving slow enough, you could station satellites at P9 sun L2 and use planet nines very cold and low frequency surface as a focusing body, Although a very dense body is preferred.

If you place radio telescopes at some distace from the sun and could peer at the ring just beyond the corona the circle, not the sun or corona you could pick up radiotelemtry from distant communications between a planet and its deep space spacecraft. A good place to do this is in the kuiper belt. So if we were actually searching and had some suspect stars (we dont, at least not locally) you could selectively dispatch space craft and simply place the in stationary positions , maintaing position with ion drives and nuclear power. Step one. find suspect local candidates stars.

-1 (-) Quoting just because you like it so much.

Gluten and tyramine intolerant, that would be a pleasant language -5/10 I buy the great lakes and move a black hole to the bottom of the mariannas trench,msucking up the entire ocean and forcing everyone to buy my water. (having the forethought to place pipelines to all the major urban areas in advance.

It can be done, getting them to Mars, getting the down or back tobEarth is a problem. Ut can be done, dont see the monetary support or the infrastructure for the number of launches required, but that's just me.

But what if life on mars was the lowest level, less advanced than anything on Earth, what if it was a few steps above a sterike lab experiment. Even if we find life on mars it still could be excessively rare. Note that rare has a real time meaning, so that if ot only existed for 500 million years the p of life on mars is 0.1 at any guven instance. I suspect that with enough digging we will find self-catalytic organic reactions on Mars that could be considered catabolic in the sense of earth life, but the next step to find communities of lineages feeding metabolites into each outher, this i have deep suspicions will not be found. Again one has to caution against making educated guesses otherwise we fall into the pitfalls of past thinkers, until we have the technology to test fir the presence of living cells on Mars we should assume that Mars is sterile as the default argument thst needs to be disproven. Otherwise we allow assumptions intonthe arguments that create a bias against using facts versus speculation.

Do not orbit the magic boulder or seek to determine its gravitational constant.

Measurements or calculations, doesn't matter. The biggest conversion question in the lab is cgs versus kms. There is the very ocaasional instance where I have to convert molarity to eqivilents at the atomic scale, very rarely. Ah yes and have to convert concentrations into LD50 values, ussually for other folks. The only time in recent memory i used an emperial measure is when we had to wax the floors in a heavily restricted area.

But the question is how many asteroids have passed close enough to Eart that we feel comfortable that we have observed all types in our system.. And, repeating, how many have we deterimed astrophysically mu. None. This is the problem in saying one is an expert, an expert of andromeda exobiology means diddly with no observations. The authors would squak at my critique, but that only because the metrics are hard. Mu is the most important single physical property that an asteroid has, this tells you how much relative energy it carries, and once average radius is determined, its tells what the average density is. Problem is we simply are making assumptions based on the interior pieces of meteors that have heated and fused somewhat on entry. Most estimates are going to be spot on, but there are likely to be a few that are lighter.
