Dyson Spheres by 2040? with Prof. Jason Wright

from Emergent Behavior · host Turpentine

Penn State astronomer Jason Wright discusses Dyson sphere detection, why building one in 50 years is physically impossible, and the search for alien technosignatures across 100,000 galaxies. Bio: Jason T. Wright is a professor of astronomy and astrophysics at Penn State University and director of the Penn State Extraterrestrial Intelligence (PSETI) Center . His research focuses on the search for alien technosignatures – especially the telltale waste heat from hypothetical Dyson spheres (megastructures built around stars to capture their energy). Wright led pioneering surveys using NASA’s WISE space telescope to hunt for mid-infrared excess emission from Dyson sphere-like structures . He is also known for his work on peculiar astronomical objects such as “Tabby’s Star,” helping show its strange dimming was due to dust rather than an “alien megastructure” . In addition to SETI, Wright studies exoplanets and stellar astrophysics, and he has been a vocal advocate for integrating technosignature searches into mainstream astronomy . - FOLLOW ON X: @8teAPi (Ate) @Astro_Wright (Jason) @TurpentineMedia -- LINKS: Website: https://sites.psu.edu/astrowright/ -- TIMESTAMPS: (00:00) Intro (03:26) What is a Dyson Sphere?

The Trials Of Women 10X Pod Group The trials of women throughout history have been marked by enduring challenges related to gender inequality, societal expectations, and limited opportunities. Women have often had to navigate systems of oppression, from fighting for basic rights such as the ability to vote and receive education to battling against cultural norms that confine them to traditional roles. Despite making significant strides toward equality, many women still face issues like discrimination in the workplace, gender-based violence, and unequal access to healthcare. These struggles are compounded by the weight of balancing professional aspirations with family responsibilities, as well as the continuous pressure to conform to unrealistic standards of beauty and behavior. Nonetheless, women continue to demonstrate resilience, courage, and leadership in overcoming these adversities and advocating for a more just and equal society.
