AI Thread Summary
The discussion centers on the theoretical concept of spacetime crystals, which are proposed to exist in four dimensions and potentially survive the heat death of the universe. Participants express curiosity about the feasibility of creating a laboratory capable of sustaining such a crystal indefinitely. There are references to similarities between spacetime crystals and toroidal electromagnetic vortices found in neutron stars, suggesting a natural occurrence without the need for human intervention. Some contributors argue that the idea remains purely theoretical and question the practicality of a crystal maintaining all ions in a lower energy state eternally. The conversation highlights the intriguing yet speculative nature of spacetime crystals and their implications for our understanding of physics.

So, I read an article yesterday about a potential design for a spacetime crystal. The idea behind a spacetime crystal/4-dimensional crystal is pretty interesting and I'm curious to know what others think about them/this.

I think I understand how a spacetime crystal is theoretically possible and could survive the heat death of the universe..but as the discovery.com article said, you would need to design a lab capable of sustaining the crystal that could also outlast the universe lol. It's an interesting idea...thoughts?

That's crazy!

Looks somewhat similar to the toroidal EM vortices found in the cores of neutron stars. And yes, those vortices might last eternally. No laboratory needed.
 
I see it as a purely theoretical exercise, impossible to realize. A crystal with all of its ions in their lower energy state ? Eternally ? Surviving the heat death of the Universe ? What else ? Surviving also the next Big Bang?
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Could fast radio bursts be alien radar signals?'

Both have short pulses of emission and a wide spectral bandwidth, covering a wide variety of frequencies: "Fast Radio Bursts (FRBs) are detected over a wide range of radio frequencies, including frequencies around 1400 MHz, but have also been detected at lower frequencies, particularly in the 400–800 MHz range. Russian astronomers recently detected a powerful burst at 111 MHz, expanding our understanding of the FRB range. Frequency Ranges: 1400 MHz: Many of the known FRBs have been detected...
