"The worst place to live on Earth is actually the safest place to live on another planet," he adds.

When that new knowledge arrives, we inevitably attempt to integrate it into our pre-existing framework, and that isn't always a smooth process. Sometimes, our foundation is riddled with misconceptions, misunderstandings, or prior teaching that were outright wrong; we have to correct and 'unlearn' those ways of thinking before we can progress.

The film then reversed the trick and zoomed back toward that Chicago couple and into their bodies to show the equally breathtaking world of our insides, down to the molecular and atomic level.

This system is truly extraordinary. We are seeing the radio equivalent of a laser halfway across the universe. This galaxy acts as a lens, the way a water droplet on a window pane would, because its mass curves the local space-time. So we have a radio laser passing through a cosmic telescope before being detected by the powerful MeerKAT radio telescope.

If a signal gets broadened by its own star's environment, it can slip below our detection thresholds, even if it's there, potentially helping explain some of the radio silence we've seen in technosignature searches. This statement from Dr. Vishal Gajjar highlights how stellar environmental factors may cause detectable signals to become invisible to current SETI instruments.

This system is truly extraordinary. We're seeing the radio equivalent of a laser halfway across the universe. Fundamentally, masers and lasers are focused beams of light in the same frequency. In the realm of astrophysics, these can arise from clouds of dust being excited into a higher energy state from the light emitted by other sources, like stars and black holes.

Now say you want to run some modest AI stuff. That's a bigger job, so let's scale up our cubical computer with edges twice as long as before. That would make the volume eight times larger (2 3), so we could have eight times as many processors, and we need eight times as much power input-2,400 watts. However, the surface area is only four times (2 2) larger, so the radiative power would be about 4,000 watts.

How the most massive objects in the universe first formed is one of the biggest headscratchers in astrophysics. With more advanced telescopes, astronomers have found fully formed galaxies and colossal black holes earlier and earlier in the cosmos, just a few hundred million years after the Big Bang. This shouldn't be enough time for these structures to reach their incredible size; to astronomers, it's like stumbling on a fully-grown oak tree that's only a year old.

For example, reader David Erickson had this on his mind: If there were aliens 66 million light-years from Earth, how big a telescope would they need to see dinosaurs? Ha! I love this question. I've thought of it myself but never worked out the mathexcept to think, Probably pretty big, which turns out to dramatically underestimate the actual answer.

We found that life is more likely to survive an asteroid impact, so it's definitely still a real possibility that life on Earth could have come from Mars. Maybe we're Martians! The idea that life could have spread through the solar system or even the universe on rocks is known as the lithopanspermia hypothesis.
