Science & Futurism with Isaac Arthur

The genesis and origin of life may require a very rare and delicate mixture of certain chemicals. One of those is phosphorus, and trying to figure out how we ever got enough of it in Earth's primordial soup for life to form in the first place has long puzzled scientists. We will also discuss the recent discovery of Phosphine Gas in Venus's Atmosphere Start listening with a 30-day Audible trial and...

Nuclear Fission was once hailed as the solution to our power & energy needs, but has grown unpopular of fears of radiation, meltdowns, and radioactive waste. However, advances in science and reactor design may make atomic energy safer and more attractive in the future.

Asteroids represent a serious hazard to Earth, past, present, and future, but will be even more of a concern to humanity as we venture out to space beyond beyond our atmosphere's protection. We will explore what technologies and methods may be available to help protect us from asteroids.

To travel to other planets, we will first have to build up are infrastructure closer to home, in orbit of Earth. The best place to get all the mass for those space stations and rocket fuel depots is from the Moon, and we'll examine the milestones we'll need to reach to start lunar resource harvesting and building up space settlements.

Spaceships and fleets of the future may host their own unique civilizations of nomads, traveling the space lanes or venturing deep into interstellar space to colonize the galaxy or flee peril. What would such cultures be like?

One possible solution to the Fermi Paradox, the big question of where all the aliens are, is that some ancient galactic disaster wiped out extraterrestrial civilizations, and we're among the first to arrive back on the spacefaring scene.

The Search for Extra-Terrestrial Intelligence, SETI, relies on looking for signals from distant alien worlds where even very powerful signals can weaken to near nothing. We'll explore today how we, or extraterrestrials, might get around this problem, be it by immense star-powered transmitters or by using laser communication beams.

Superconductors offer us a path to high-efficiency, low-loss power and energy, but the impact they'll have on our civilization through other technologies may be far greater, and we'll explore the science or superconductivity works and what future technology it will of us.

If the Universe is inhabited by older alien civilizations, those who have ventured out to the stars and colonized galaxies, we would expect to see a footprint of extraterrestrial activity. Could the many stars whose brightness has dimmed be indicative of Dyson Spheres or other Megastructures? Could the Cosmic Voids vastly bigger than any galaxy be the work of even greater and older starfaring spec...
