  • Republicans are raising taxes for middle class and poor

    Casey begs for the listeners to become a member and donate to them on one hand, while he promotes billionaires’ business ventures on another hand.

    Republicans keep raising taxes for regular people, by way of tariffs, and lowering taxes for rich people, by way of the Big Beautiful Bill, making regular people even poorer. But that doesn’t stop this podcast from begging for more donations from regular people. Somehow the rich keep getting richer while the rest of us keep getting screwed.

  • So-S0

    Generally ood science/astronomy content, but unfortunately tainted with DEI dogma and recurring leftwing political bias…. Could use a bit more “diversity” and “inclusion” when it comes to worldviews and obvious bias.

  • Casey Dreier & Mary Guenther

    These 2 people are out of touch with Middle America and have no clue of anything that happens here. People are poor, people have lost everything, people are scared and people are dying. Billionaires have taken over our country and these two don’t seem to get it or even care. Stop robbing from all the poor Americans and giving our cash to the wealthiest Americans.

    P.S. Poor people don’t do polling, so please don’t give us the polling numbers from now on.

  • Look up at night sky and be inspired!

    As an artist living in the USA, I have always been interested in the mysteries of the night sky and how little old me figures into the grand scheme of space! I always inspired by the Apollo missions. It might have been my innocence of youth that made me think everyone loved space flight and exploration of the universe like me! Out on the farm where I grew up, it was so dark at night that one could see satellites, planets, the edge of the Milky Way and what I called “foreverland ”! Outer planeta... more
