About This Episode

What awaits us beyond our solar system? What mysteries can we uncover once we venture further beyond our home star? Join astrophysicist Janna Levin and comic co-host Matt Kirshen as they answer fan-submitted Cosmic Queries on interstellar travel, black holes and the furthest reaches of our universe. Explore a variety of questions concerning black holes: from traveling through them, to what happens when two black holes collide, to the possibility of worm holes inside of black holes. Janna explains how time travel is possible through nature without the requirement of technology. Discover more about how dark matter and dark energy could play a factor in interstellar travel, and the idea of our universe having more than three dimensions. You’ll learn why gravitational force is weak compared to electromagnetic force and how that could relate to the existence of other dimensions. Find out about time dilation and how it would impact you when traveling near or at an event horizon. All that, plus, find out about traveling at the speed of light, the possibility of sending a satellite somewhere in the universe to look back in time on the Earth, and much more!

    At around 40:00, it looks like you said “you fall into a black hole at speed of light”. Can I assume that you mean stuff usually fall into a black hole at speed of light?
    If so, + knowing that nothing can go faster than speed of light
    1. If a rocket make a full speed accelerating itself head on into a black hole, it can fly faster than speed of light?
    2. If a rocket make a full speed accelerating itself head on into a black hole, it won’t make a difference than turn off the engine and let the black hole suck it in?

    If #2 is truth, then where is accelerated energy from the rocket engine could possibly go?
