Scientists have created a simulation of a wormhole in a quantum computer. Top quark helps us understand the significance of this as well as reminds us what the heck a wormhole is anyway. In planetary science, collisions may once again come to the rescue to help explain a mystery. This one is the odd gap in exoplanet sizes. And Down quark gives us an update on the Lucy mission to the Trojan asteroids and its sticky solar panel. Join us for all this, telescope trivia and more.
If singularities make your head hurt, let Planck Stars bring you back from the infinite. With the ability to contain all the information that falls into a black hole, these stellar wonders are supported against collapse by the stiffness of reality itself. Thank Heisenberg for these paradoxical stellar beasts whose unproven existence depends on loop quantum gravity theory. If that's got your head spinning, jump into a black hole for a ride with a Planck Star. Planck Stars, find what feels good (Yoga with Adriene).
