I am not so sure. If interstellar travel is solvable, then some alien species would have solved it a billion years ago. The mere fact that we are not overrun by alien species makes me think that the problems may not be solvable.

I think you guys need to move somewhere where it isn’t winter half of the time. How about Florida?

Went back in time. Killed Grandpa.

Ye, the trailer is evidence of life from a long, long time ago and in a galaxy far, far away.

I remember seeing a concept for a Venus rover. The concept was actually to have a non-cooled probe land on the surface. The concept was interesting as the electronics and mechanical hardware would all be designed to operate at Venus surface temperatures. Insane, but apparently theoretically possible.

Actually, a Uranus orbiter wouldn’t be a bad idea. It would probably take 15 to 20 years to get there, but it’s an idea. . .

What if we are the (radical thought) only?

No, they are looking for waste heat. This heat is the inevitable byproduct of any thermodynamic process that utilizes energy. You can come up with many ways to reduce this heat, but it cannot be eliminated. The article is a little vague, about exactly what the researchers were measuring, but I am guessing that they…

Actually, the study indicates that the starlight is not being used, neither by Von Neumann nor by “inhabitants”. I am not sure what you mean by “inhabitants”. Could this term include artificial intelligent lifeforms? If so, than the Von Neumann probes are the civilization.

Type 2 and 3 civilizations would not live on planets — planets are too small and restrictive and waste material by concentrating it into a large sphere, the center of which cannot even be accessed. These civilizations will use solar energy to disassemble planets so that the material can be used more efficiently. On…

No, it relies heavily upon the assumption that one star among 200 million in a galaxy will generate alien life like us. It only takes one species per galaxy to do this, and there are 200 million possible opportunities.

A species would control more energy to avoid individual death and by extension species extinction. The way to do that is to control more of the natural world. The energy output of a galaxy becomes controlled by individually controlling each star by channeling its energy for use and to increase. Perhaps some species…

Hmmm. . . you know, it used to be considered closed minded not to consider that there is intelligent life elsewhere in the universe. Judging by the comments things have changed. Now it looks like it is close minded not to consider that there is no intelligent life elsewhere in the universe. People, open up your minds.…

Go where? Pick a place? Right now there don’t seem to be any likely destinations to search.

No, it is deeper that that. What the results imply is that across 100,000 galaxies, each of which has around 200 million stars (for a total of 100 billion opportunities), each one a potential source of an advanced civilization, not a single one was able to develop into a K-3 civilization (yes a human concept, but so…

Yes, that has been the argument for the last few decades, and while the absence of evidence for intelligent alien species is not proof of non-existence, it seems that every day the likelihood of its existence decreases. I realize that it is very premature to start asking this question, but what if we really are alone…

While all that is possible, it is incosistent with our basic understanding of the universe are requires new physics. Is this possible, yes. But I wouldn’t hold my breath.

Yes, that is interesting. Compared to their size, galaxies are relatively close to each other (on the order of 10 to 100 times their diameter). Planets and stars are many orders of magnitude more separated compared to their size. But there is still a lot of emptiness out there.

Yup, the cost of dealing with that rise is less than the cost of dealing with not burning it all. I choose the cheaper solution.

Wait. . . 2 meters in 1000 years??? I live in South Florida and my property will still be here then. If that is the kind of ocean rise we are talking about, then we might as well just ignore it. Just stop spending money trying to prevent it (i.e. government backed insurance in flood zones) and let the ocean slowly…
