  • Seriously mind expanding stuff!

    My YouTube subscription history is pretty fickle, with the exception of SFIA. This podcast is a great way to catch up on the go, with over a decade of content related to futurism and covers topics that you won’t find anywhere else.

Talking Points

Recent interactions between the hosts and their guests.

SFIA Monthly Livestream 60: December 31, 2023
Q: How would you actually get the materials needed to build large rotating habitats in orbit?
Isaac specifies that building habitats in orbit would depend on advances in launch technology, and that Earth remains a primary source for raw materials.
SFIA Monthly Livestream 60: December 31, 2023
Q: Do anti-matter rockets have to be thin and long as often depicted, or is there some design flexibility if we invent better anti-matter production and storage?
Isaac explains that rockets are depicted as thin and long primarily to reduce impact with space debris, but design flexibility exists depending on anti-matter technology advancements.
SFIA Monthly Livestream 60: December 31, 2023
Q: Is it generally accepted that gravity causes time dilation, and is there an alternating theory that time dilation actually causes gravity?
He suggests that while one can argue both sides, he treats it as gravity causing time to slow down based on current scientific understanding.
SFIA Monthly Livestream 60: December 31, 2023
Q: Could utility fog or programmable matter be of some kind be used as a force field that could stop bullets?
Isaac discusses how utility fog could serve as a shield against bullets by moving quickly to intercept them but notes its limitations against faster projectiles.
