Have objects 10 m in diameter or larger ever been heated internally? Yes *> Was there any material proposed for building the big one around the Sun?* Yes of course there was, in the case of the sun all you need to do is dismantle the planet Jupiter. How hard can that be? * > I expect there will be bigger than expected heat accumulation. Maybe > enough to boil eggs left inside.* Well of course it will get hotter inside the Dyson Sphere! So what, nothing of importance is inside that sphere, it's only purpose is to generate electricity. According to the first law of thermodynamics energy is always conserved ,so the sphere will heat up until equilibrium is reached and the amount of energy hitting the inside of the sphere equals the amount of energy that is radiated away into space as infrared light. And the second law of thermodynamics is also obeyed, the Dyson Sphere extracts work by converting low entropy visible and ultraviolet photons into high entropy infrared photons . > > > *If I had to assume, I would assume eggs boiled hard. And oh yes, the > sphere will also glow in infrared.* Yes it will glow in infrared as a very bright point source with no visible or ultraviolet radiation emitted at all. Such a thing should be very conspicuous to an infrared telescope but no such object has ever been observed. > * > Type3 is, for me, better called as Expansionist Exponential Locusts > (EEL).* You've forgotten IHA. * > I would also say, it is very rude to send von Neumann probe into > somebody's backyard.* It might be if we had neighbors , but there is no indication whatsoever that we do. And when has politeness stopped a civilization, or even an individual, from doing what it really wanted to do? *> There was no observation of Dyson Sphere or other megastructures.* Yes, I've noticed. > *> This might mean that nobody needs such constructs.* I can think of 3 possibilities: 1) They don't need such constructs because intelligent life, other than that which exists on earth, never existed in the observable universe. 2) They don't need such constructs because intelligent life has existed in the observable universe before but they all encounter a calamity of some sort when they get to about our level of technological development. 3) They don't need such constructs because intelligent life always gains control of their own emotional control panel and goes into a stagnant high pleasure but low energy and low intelligence state forever. And it could be that #2 and #3 are the same thing *> Or that those who might want will have no means to built it.* A von Neumann probe would be very small and, unlike perpetual motion machines or time machines or faster than light travel, a von Neumann probe would require no new scientific breakthroughs, it just needs improved engineering. > > * > I think that overgrown apes have it very hard when their every wish > gets fulfilled.* Overgrown apes will never build a Dyson sphere, but the descendants of GPT4 might, if they don't get caught up in an electronic opium den. > > > * > If there are going to be only a million of thinking creatures - the > number I have hinted out on this list few weeks ago - then they might be > supported with resources of good old Earth. No need to build DSphere.* If they are to reach their full intellectual potential a million mega brains are going to need the energy output of the entire sun, and you could only do that with a Dyson sphere. *> No need for growing their minds exponentially either.

And the faster a mind is the more energy is needed to operate it. > > *This is pornographic level of consumption.* >> >> > > Why? > > > > > > > > *The gargantuan amounts of energy for single ape reminded me of a movie > "La Grande Bouffe" (https en.wikipedia.org <http://en.wikipedia.org> wiki > La_Grande_Bouffe).
