    Cosmic strings may be ultra-thin defects in spacetime—relic “cracks” from the early universe. How we’d detect them, what they mean for physics, and how aliens might exploit them.

Even if you like your sci-fi more as space fantasy. SFIA is a great showcase of the immensity of scale that most Sci-fi lack and just what wild and crazy stories could be written about that never really get any love in modern literature.

Great resource for writers and fans alike.

I don’t know how he does it, but Isaac is able to weave unique storytelling with physics in a way that few people can.

The best of our time

I've been listening to Isaac's videos / podcast for probably close to half a decade now. I've always had a love for science but he always makes me fall in love again with both the incredible depths be dives to but also the optimism he constantly shows.

Is it Arthursday yet?

I've been following Isaac Arthur for many years now. he has been my go-to podcast while I'm driving or sometimes bed going to bed. I consider him an encyclopedia for the future humanity is going to face. thank you, Isaac

I also use this man's show to fall asleep to! The ideas are so big and the narration so friggin smooth I just can't help it! I came upon him so many years ago when he was worried about his speech but man!! It just didn't really matter. I can listen to you all day my man! You rock! Favorite. Podcast. Ever. Hands down. Even the kids delve in when they need a little thought provocation. Enjoyment for the whole family. Trust the reviews!!!!!

This Guy!!
