A Dyson sphere is a hypothetical megastructure that encompasses a star and captures a large percentage of its power output. The concept is a thought experiment that attempts to imagine how a spacefaring civilization would meet its energy requirements once those requirements exceed what can be generated from the home planet's resources alone. Because only a tiny fraction of a star's energy emissions reaches the surface of any orbiting planet, building structures encircling a star would enable a civilization to harvest far more energy.

They only work during the day though.

I pirated this to check it out and enjoyed it so much that I bought it even though it's in Early Access and that's very very rare for me. I still haven't played it more though as I'm still waiting for it to come out of EA, looking very much forward to play it again.

I'm the same lol. I bought several books in print after pirating the ebooks.

$20 is the perfect price IMO

edit: pirating this game is kinda funny to me, its a Chinese Dev. team so who knows if there are assets in the game that are not legit. I will probably buy it but I wouldn't shame anyone who did find another way to get it without purchasing it

Damn that looks cool

[-] Spacehooks@reddthat.com 29 points 1 week ago

Be carful with those. You may block the light of constellation aliens use and really piss then off.

[-] rockerface@lemm.ee 17 points 1 week ago

Eh, they won't find out until a few centuries later anyway

[-] Spacehooks@reddthat.com 6 points 1 week ago

Well unless they are monitoring or are relatively close. The issue was they got annoyed cause their decedendants won't see their "holy constellation". Something like a north star to them I guess. So anyway I started a purification campaign In response.

...no, they won't know for a few hundred years due to the actual speed of light and vast distances of space.

[-] neatobuilds@lemmy.today 4 points 1 week ago

Unless they have some fancy alien sensor with quantum entangled particles so they get an alert instantly

[-] Spacehooks@reddthat.com 1 points 1 week ago

You're assuming they are not part of the deep state already!

"People of Earth, I am Lrrr of the planet Omicron Persei 8."

You need to watch more Star Trek, friend.

Specifically "The Next Generation", Season 6, Episode 4, " Relics".

Thank me later. 😁

[-] OpticalMoose@discuss.tchncs.de 4 points 1 week ago

Classic episode; one of my favorite

[-] FlyingSquid@lemmy.world 3 points 1 week ago

With a bottle of green.

A pinnacle of science, a wonder of engineering, that we will never get to see in our lifetimes. Instead, we get to see Taiwan get nuked or something, I don't know. I don't follow the news much, I only know I'm disappointed.

[-] QuantumSparkles@sh.itjust.works 2 points 1 week ago

If we could just speed up cryogenics or hibernation technology…

[-] thisbenzingring@lemmy.sdf.org 2 points 1 week ago* (last edited 1 week ago)

Taiwan is too valuable to nuke. It will be squeezed with a lot of Navy to land attacks, destroying many of the places people live but not the places they work. Then urban warfare will be the rest and it will probably be death of millions.

Wait! The same problem Larry Niven’s Ringworld have also applies to Dyson Spheres? Huh! Saving to read later.

[-] batcheck@lemmy.world 4 points 1 week ago

Came here to say that if you like this concept, Peter Hamilton has a book series called Commonwealth Saga in the science fiction category that is excellent. Lots of pseudoscience from early 2000s in that series.

Great author!

I've played that Stellaris mod, pretty sweet

[-] merdaverse@lemmy.world 1 points 1 week ago

It's a pretty cool concept, and I enjoyed building one in Dyson Sphere Program, but I don't really understand how you would transport that amount of energy to where you need it. Are they like mirrors that redirect and focus light to some point?
