Dyson spheres come up a lot in science fiction, as well as in discussions around alien civilizations. But what are they? Do they exist and the even bigger question... Could humans ever make one?

I vacuum my rugs with a Dyson sphere every day what's this guy on about.

Aliens "Shit they can see us. Oh they think randomly dimming stars are natural, good we don't have to talk to them yet"

1977 Aliens: “SOS, Help us our world is dying”. 2020 Aliens: “WHY THE HELL HAVEN’T YOU HELPED US”?

Sadly, humanity’s biggest hurdles are social, not technological.
-
"um...Earth." You gotta love the commitment to a running gag.
-
"The Kardashian Scale": Illustrates the level of continual regression human civilization is capable of.
-
I think a Dyson swarm has one big advantage: when the time comes to pack things up and run it would be much faster than dismantling a Dyson sphere. It could be rearranged away from the star during the supernova blast and wait for the star to become a white dwarf to rearrange it again.
-
The solar wind info is understated, thanks for covering that. If the shell were of uniform thickness, you'd experience only the Sun's gravity when inside the shell. This basically mean all the energy you're trapping arrives beneath your feet.
-
The shell idea is basically like levelling your own house so that you can never pay for utility bills ever again.

"You can't destroy the Earth! That's where I keep all of my stuff..."

It would be cool to see Joe go through how humans would progress through the stages.

I’ve already started on mine. Dyson Sphere Project

5:55 Watts per second is a misnomer. Watts already measure the rate of energy use.
-
Good timing for this video! A game called Dyson Sphere Program just entered Steam Early Access. It's sort of like Factorio and Satisfactory had a baby, and that baby decided to build a giant ball to play with. You pick a random star cluster with up to 64 solar systems to mine for resources. They even have neutron stars and black holes, though I am not sure what those do,

When I imagine a dyson sphere my head goes straight to the Death Star.
-
"How do we stop global warming and move towards renewable energy?" Google: You can use solar power, wind power, even fusion and fission... Bing: BUILD A DYSON SWARM
-
Destroying Earth? Earthlings: "Challenge accepted".
-
5:53 What in the universe is a watt per second? A watt is one joule per second, which is a measurement of power.

Joe, you should upload these as podcasts on Spotify, would be awesome.
