]. I’ve known Claudio Maccone for 20 years now. He’s the one who really – he and Greg Matloff are the ones that really got me sucked into the interstellar community. And Claudio is a mathematical savant. I mean, he’s just amazing. But his whole thing now is this whole gravitational lensing for communications and for looking at exoplanets. Now, you may have heard of the work thatM:to image exoplanets that would provide insane resolution?Right.
The reason why we may not be picking anything up on SETI is because these different civilizations are all talking to each other from the gravity lens point. And there’s no leakage. And in order to join the network, you have to get one of them to recognize that you’re there and beam something to your surrogate Solar Gravity Lens region.
We had a few points of disagreement, notably between most of us and Philip Lubin. Phil had just done a recent cost analysis, just in energy costs, of how much it would cost to send an interstellar ship. And that caused quite a discussion. Because I personally, I think it’s an irrelevant number because by the time we do this, what is the energy price going to be? And what is money going to be? So there are some definite differences.
we’re ready.” I think AJ and Erica might take issue with us being socioeconomically, sociologically, and psychologically ready. But that’s an important question, “Are we as a culture ready to do this?” And I think there’s some legitimate debate to be had here.

Unveiling the Cosmos: Maisie’s Galaxy Confirmed as One of the Universe’s OldestMaisie's galaxy, named in honor of Steven Finkelstein's daughter, was detected 390 million years after the Big Bang. The James Webb Space Telescope has enabled astronomers to confirm that a galaxy initially spotted last summer ranks among the earliest ever observed. These findings were recently pub

Turbulent Plasma: Uncovering the Source of the Universe’s Magnetic FieldsThe source of magnetic fields has long been debated. New research offers clues on their origins. It isn’t just your refrigerator that has magnets on it. The earth, the stars, galaxies, and the space between galaxies are all magnetized, too. The more places scientists have looked for magnetic fiel

A New Way to Measure the Expansion Rate of the Universe: Redshift DriftAlmost all the galaxies in the Universe are speeding away from us because of the Big Bang and the acceleration of dark energy. One technique to measure this expansion is redshift, seeing how light is reddened over time as its wavelength stretches out. But every observation astronomers can make is a snapshot, measuring the redshift now. But an intriguing idea is to measure how the redshift changes over time as a galaxy's movement accelerates. It's called 'redshift drift' and requires an exact series of measurements over time.
