Using Earth to See Across the Universe: The Terrascope with Dr. David Kipping

Can we see the end of the universe?

The greatest discoveries in science often sprung from outside of the box thinking. It could be said that both Newton and Einstein came up with their ideas initially simply by taking a fresh look at how we describe our universe. What’s currently important is that fresh ideas get looked at and debated. That’s innovation, and it’s all around us currently from SpaceX revolutionizing the aerospace industry to murmurs of private efforts to harness fusion. 

But what else might we do? My guest Dr. David Kipping has come up with an idea for a new type of telescope, not using mirrors or lenses per se, but the earth itself perhaps eventually giving us an entirely new way to view our universe.

Professor David Kipping speaks with John Michael Godlier about a solution for turning the Earth into a “Terrascope”, an earth sized telescope. Also discussed were the SETI implications of using the Terrascope as well as using it to send signals out or if alien civilizations and technosignature implications.

  • He's not the only one to refer to the James Webb telescope as the "James Woods telescope" lol.

  • I have been watching Event Horizon for a couple of years and really have enjoyed and learned from all of it. I really have enjoyed the new format with guests being interviewed. Thanks John.

  • Mars doesn't have any ozone in it's atmosphere.

    Let's convince Musk to launch the Tesla semi truck (is that even a thing still?) At Mars and we can just put the package in the back. Haha

  • Reminds me a little of the novel Macroscope by Piers Anthony. the SDPS The Super Duper Pooper Scooper.

  • So, how much more magnification would you get if you used Jupiter or some other of the outter solar system planets?

  • Cool thought experiment. The only thing is, your sattelte is allways fixed in the same position trying to see whats exactly behind the earth. You can not move to any other position. That means an exoplanet must be EXACTLY on the other site of the earth . You can position yourself for that. but then your stuck there forever. You can not scan the skies so to speak. because the earth is moving arround the sun the position changes and you will see that planet / start only for a short while, about 1 day. The chance that an exoplanet has its transit at that moment is so so so tiny… But the idea is cool. I would support it anyway. Also, the see pollution in that exoplanet would not work because of the same pollution in our atmosphere.

  • If the gravitational focus is past 550AU for our sun and for every distance beyond that, why not put a satellite into orbit and use the focus line from another star like Epsilon Eridani?

  • It will, if there's any justice, be called the "Kipping Orbital Terrascope System."

  • Presumably, at that distance, you would also likely have some looses due to larger storm systems particularly hurricanes as they can have cloud tops that can be in excess of 15 km if I am not mistaken. Could be wrong about that but I know that even the high service ceilings on business jets fall short of the cloud tops of some hurricanes think Concorde was the only civil aircraft that could reliably get far enough over them and even then not sure it was exactly recommended as the turbulence can get even higher. And they are freaking huge too like 1-2% of the circumference being affected by the cloud cover from a big one as they can push the better part of 1000 km. Note this is not saying that it's a bad idea just seems that the cirrus cloud is not the only cloud that can be an issue at 14 km.

  • Wouldn't a (small) artificial black hole be almost useless for this? Sure for any black hole you would not have to be particularly far from it to get an Einstein ring (actually I don't think there is any distance from it where you can't get a ring save within the horizon itself) but what matters is the light collection it adds, and a small black hole just wouldn't have the gravitational attraction to take in enough light over a given area of space to rival even a normal telescope. Maybe if planet X did end up being a 10 Earth mass black hole it would supply enough lensing to be better than nothing?

  • New to the channel, very glad I found it. I think I'm probably watching things out of chronological order but I'm really enjoying the recurring domestic squabbles between John and AI Anna over the Chevy Malibu. 😉

  • If you're not able to spot ozone with this telescope, it seems like you could setup another space telescope around a nearby planet like Venus with an atmosphere that lacks ozone.
