Dyson Sphere, What's the point.

If you were capable of building something around a star to harness said stars power, you probably wouldn't need to in the first place.

Agreed, extracting as much material as we can to delay the death of the sun should be a priority and we could just use that material for fusion.

It's called star lifting.

There is no greater known power source than dyson swarms. Perhaps you could get slightly more out of the material by dissassembling the star and then burning the fuel yourself in a fusion reactor but that basically requires a dyson swarm to do anyhow.

what kind of power source would be required to put a dyson swarm in orbit is my question tho. cause it (feels) like such a power source would make the endeavour second best to it.

Smaller swarm, you just start out with few bits and then use the power to build more. It's not a hard concept

Don't think the only resource necessary to increase the size of the swarm is energy.

When you are talking about things on a scale of a dyson swarm then the only real limit is energy, you can always just disassemble planets or starlift for materials.

No, spaceplanes are.
We're now realizing taking a plane and adding massive auxiliary rockets and drop tanks does about as much sense as taking a car and adding wings and a propeller.

Dyson sphere is like pondering about building tower to heaven in 2000bc.

they're virtually useless for passive living, but they make incredible doomsday weapons. point the beam anywhere you want to destroy anything you want; even a weak beam would eventually destroy a habitable planet with no way to stop it.

hypothetically, since the idea of a dyson swarm is already fantasy, we can go a step further and say that the energy collected from a dyson swarm would be high enough to facilitate raw matter fusion to literally create matter from nothing but pure energy, which could then be used to make more dyson swarms.

>>13445634
you're not thinking in terms of timescale. you'd have to go out of universe to get enough raw materials to build a full sized dyson swarm, as well as the materials to build the equipment and structures to construct those dyson swarms, as well as the materials and equipment to collect and refine the raw materials to build both the structures and the dyson swarm, alongside the equipment and structures need to find and collect the raw materials.

get a load of the sense of entitlement on this soigoy. the petulant moron saw a space ship in a marvel comix movie and now hes angry that it isn't real and
>its all everyone else fault!
retard can't even do an old change on his mom's minivan, but he expects everyone else to busy themselves building space ships for him.

Quoted By:

Accounting for distances and the speed of light. No visible civilization has yet to build a Dyson structure. As it would be plainly obvious, because the differences in infrared and visible light imagery. Dyson structures would be very bright in infrared. While dim or invisible in visible light.

Any civilization capable of building such a structure. Would also have practical and timely(centuries) travel between stars. Where they would continue building more Dyson structures. Before another colonial wave to the next nearest stars from that star. So on until a region of a galaxy is very dim in visible and very bright in infrared.

It may come as a surprise, but we already started to build a dyson swarm. Every solar panel on earth, in orbit or on a space probe is another small step.
