What if the ultimate technology isn’t a starship, but a universe? We explore simulated worlds, baby universes, black holes, false vacuum bubbles, and whether civilization could one day create realities of its own. Get Nebula using my link for 50% off an annual...
White holes are black holes run backward: nothing can enter, but matter and light can escape. We explore whether these strange solutions could exist, connect to black holes, or even hint at how universes are born. Get Nebula using my link for 50% off an annual...
Space looks freezing, but “cold” works very differently in a vacuum. Without air to carry heat away, objects in space can actually stay hot for a surprisingly long time. #Space #Science #Physics #Astronomy #SpaceFacts #SFIA 🚀 Join this channel to get access to perks:...
Mercury may be the Solar System’s first true industrial world. We explore robotic mines, solar furnaces, mass drivers, mobile cities, and how the innermost planet could help build a Dyson swarm. Get Nebula using my link for 50% off an annual subscription:...
What if we could make gasoline from air? We explore how carbon dioxide, water, and electricity can become synthetic gasoline, jet fuel, rocket propellant, plastics, and more. Get Nebula using my link for 50% off an annual subscription: https://go.nebula.tv/isaacarthur...
How close could a spacecraft - or a human - really get to the Sun before heat and radiation win? Let’s push the limits and find out where survival stops being possible 🚀 Join this channel to get access to perks:...
