Exo Wombs and the Faint Young Sun Paradox

To combat low population growth, some countries are looking into using artificial wombs to grow new humans. Anthony and Jeff examine this dystopian idea to see if it might actually make sense. Then, we know the sun – and all stars – get hotter and hotter until they die. But what we rarely consider if how a younger sun would have been dimmer and cooler. Jeff and Anthony take a look at the paradox of how life on Earth emerged when it would have been too cold for oceans to flow.
