A train of spacecraft sailing the sun’s light to a magical point out there in space where the Sun’s own gravity turns it into a gigantic lens. What could such a solar-system-sized telescope do? Pretty much anything. But definitely map the surfaces of alien worlds.

    How To Capture Black Holes

This insane hypothesis is getting closer to reality, according to the papers in today’s space time journal club. Hosted by Matt O'Dowd Written by Matt O'Dowd Graphics by Leonardo Scholzer & Adriano Leal Directed by: Andrew Kornhaber Executive Producers: Eric Brown & Andrew Kornhaber End Credits Music by J.R.S. Schattenberg: https://www.youtube.com/channel/UCRl6-nb4iOnsij-vnpAjp0Q Thanks to LIGO we’ve now seen black hole mergers, but there was some striking surprises. For one thing, many of the merging black holes were too massive to have been formed by the collapse of stellar cores. That is if our understanding of stellar evolution is half as good as we think it is. This led astrophysicists to think about new ways to produce black hole mergers. Here’s the most awesome possibility: what if black hole mergers actually occur in orbit around supermassive black holes, embedded deep in the whirlpools of searing gas that surround some of these monsters? Today on Space Time Journal Club we’ll be looking at a pair of 2019 papers that talk about this possibility. We have Yang et al., which predicts the properties of black holes that merge this way, and McKernan et al. which proposes a way for us to actually test this hypothesis.

    Do Black Holes Create New Universes?

To support your local station, go to: http://to.pbs.org/DonateSPACE What if every single black hole that formed in our universe sparked the big bang of a new universe? Cosmological natural selection proposes exactly this - but even better, it claims to be able to test the hypothesis. Sign Up on Patreon to get access to the Space Time Discord! https://www.patreon.com/pbsspacetime Sign up for the mailing list to get episode notifications and hear special announcements! https://mailchi.mp/1a6eb8f2717d/spacetime Check out the Space Time Merch Store https://pbsspacetime.com/ Physicists have been struggling for some time to figure out why our universe is so comfy. Why, for example, are the fundamental constants - like the mass of the electron or the strength of the forces - just right for the emergence of life? Tweak them too much and life, stars, galaxies, the universe as we know it wouldn’t exist. In recent episodes we explored one possible explanation for this - the anthropic principle and the idea of the multiverse. If there are countless universes with different fundamental constants, then it’s not surprising that a few exist with the right numbers for life - and certainly not surprising that we find ourselves in one of those good ones. But if you don’t like the anthropic principle - and many scientists don’t - then rest assured, there’s an alternative. You only need to accept two things: that our universe formed inside a black hole, and that universes can evolve.

Why? Because we can use them as futuristic power generators, galactic-scale bombs, and portals to other universes. Hosted by Matt O'Dowd Written by Matt O'Dowd Graphics by Leonardo Scholzer, Yago Ballarini, & Pedro Osinski Directed by: Andrew Kornhaber Executive Producers: Eric Brown & Andrew Kornhaber End Credits Music by J.R.S. Schattenberg: https://www.youtube.com/channel/UCRl6-nb4iOnsij-vnpAjp0Q Black holes are self-sustaining holes in the fabric of spacetime. Space at the event horizon cascades downwards, dragging more space behind it, sort of like how water drags itself near the edge of a waterfall. In a Kerr black hole, space above the event horizon is dragged around in a circle - so less waterfall and more whirlpool. Water spiraling down a drain in a flat sink doesn’t know about the hole - it only knows about the motion of the water around it. In fact it’s possible to construct a black hole in general relativity rotating or otherwise - without any mass. Warp spacetime so it looks like the exterior of a black hole, and that warping will persist. So what is rotating? Spacetime is rotating.

But there’s one bit of nonsense that is perhaps more persistent than all others: the perpetual motion machine. No working perpetual motion machine has ever been experiment verified. All break the laws of thermodynamics. In fact, we classify based on WHICH law of thermodynamics they break. We have perpetual motion machines of the first kind - they violate energy conservation - they pump more energy out than they need to keep running. This includes most of the historical devices. Then there are machines of the second kind - they’re a bit more subtle in their wrongness because break the second law of thermodynamics - extracting energy by reversing entropy. Many modern “free-energy” devices fall into this category. Now the best modern designs are by you - answers to our recent challenge question, which we’ll get to at the end. But first let’s take a look at examples of what other people came up with - this’ll be a fun little journey through some pretty terrible science.

Hosted by Matt O'Dowd Written by Matt O'Dowd Graphics by Kurt Ross Directing by Andrew Kornhaber Designing a perpetual motion machine has a very long history and became quite the craze from the middle ages through the renaissance. The first well-documented design for a perpetual motion machine was from the 12th century. Bhāskara's wheel, named after the Indian mathematician, was embedded with tubes of mercury that would flow from back and forth as the wheel turned. Other types of over-balance wheels followed through to the Renaissance and worked on the same principle. There were also designs that employed the magical-seeming lodestones – magnets. For example, this ramp in which a ball is pulled to the top by a magnet before falling through a hole and rolling to the bottom again. Then there are the self-pumping waterwheels or self-blowing windmills.

In the world of quantum mechanics, it’s no big deal for particles to be in multiple different states at the same time, or to teleport between locations, or to influence each other faster than light. But somehow, none of this strangeness makes its way to the familiar scale of human beings - even though our world is made entirely of quantum-weird building blocks. The explanations of this transition range from the mystical influence of the conscious mind to the grandiose proposition of multiple realities.
