Hybrid Astro Lecture - Black Holes, Spaghettification, and Time Travel
Hybrid Astro Lecture - Black Holes, Spaghettification, and Time Travel
Can we abuse gravity to achieve time travel or to visit distant galaxies? What is preventing us from turning science fiction into science fact? Join us for a 30-minute lecture on the counterintuitive side of gravitational physics, followed by a panel Q&A consisting of several astrophysicists to answer your questions about space science.
Dr. Nils Deppe is a postdoctoral fellow in theoretical astrophysics at Caltech and will be starting as an assistant professor of physics at Cornell this summer. He uses computer simulations to study black hole and neutron star collisions, providing predictions for what scientists using LIGO and other instruments should observe. Outside of work he enjoys hiking, backpacking, music, hanging out with his cat, brewing hard cider, and playing Mario Kart with his partner.
Abstract:
Gravity on Earth is quite boring: it makes apples fall. However, near a black hole things get really strange. Time slows down and everything becomes spaghetti. Can we abuse gravity to achieve time travel or to visit distant galaxies? What is preventing us from turning science fiction into science fact? Come learn about the wild and whacky side of gravity and how black holes are too weird even for Hollywood sci-fi movies like Interstellar.
Living on Mars time by a Mars Rover Pilot
Monday night, we had a great set of talks on rocket design and piloting the mars rovers at our Astronomy on Tap. Here are a few clips. Talks by Justin Foley and Tina Seeger.

Hybrid Astro Lecture - Fireworks from Black Holes Devouring Stars
Hybrid Astro Lecture - Fireworks from Black Holes Devouring Stars
While supermassive black holes themselves do not emit light, they can be "awakened" when a star gets too close and is torn apart by their powerful gravitational forces. Join us for a 30-minute lecture on how black holes consume stars, followed by a panel Q&A consisting of several astrophysicists to answer your questions about space science.
Speaker:
Yuhan Yao is a PhD candidate at Caltech. She uses optical sky surveys and X-ray telescopes to study the most energetic phenomena in the universe, such as the explosion of stars, and the extreme environments around neutron stars and black holes. In addition to astronomical research, she likes coffee, window shopping, and Japanese anime. https://yaoyuhan.github.io/

Title: The Invisible Atmospheres of Galaxies
Abstract:
Galaxies are dynamic, evolving objects consisting of stars, gas, and dark matter, and are as diverse as the people on this planet. In order to understand why galaxies look the way they do and why some die (stop forming new stars) while others thrive, it is important to understand the environment in which they live. In this lecture, I will discuss how galactic atmospheres (referred to as the circumgalactic medium) are key to understanding galaxy evolution, and perhaps, our own existence in the Milky Way. I will highlight recent observations, taken with the Hubble Space Telescope, that challenge existing theoretical models and discuss possible solutions from recent research.

Hybrid Astro Lecture - Finding Earth 2.0
Hybrid Astro Lecture - Finding Earth 2.0
After 30 years of relentless planet hunting, our Solar System is now just one example amongst a mind-boggling variety of planetary systems. Only a small fraction of these 5000 exoplanets have had their picture taken, yet taking direct pictures of exoplanets and analyzing their light is the only way astronomers will one day find an exoplanet the size of the Earth orbiting a quiet star like the Sun. Join us for a 30-minute lecture on the search for Earth-like planets, followed by a panel Q&A consisting of several astrophysicists to answer your questions about space science.
