Using Technology to stop the expansion of space.

AI Thread Summary
The discussion explores the possibility of using technology to halt or manipulate the expansion of space, particularly by addressing dark energy, which is believed to drive this expansion. It is noted that cosmic expansion primarily impacts vast scales, specifically megaparsecs, while smaller structures like galaxies remain stable due to their internal binding energy. Participants express skepticism about the feasibility of such manipulation, given the current understanding of space and time. The conversation highlights the potential long-term effects of cosmic expansion on fundamental forces if left unchecked. Overall, the idea remains speculative, emphasizing the need for further understanding of the universe.

I was wondering if anyone ever thought about using technology to stop the expansion of space, or at least a section of space.

Much like how sections of space-time are warped by large physical objects, perhaps large sections of space-time can be warped to stop expanding (by somehow manipulating the dark energy that may be causing the expansion in the first place?)

Any ideas?

This is also assuming that it is dark energy that is causing the expansion.

I also don't think we fully understand space/time or the universe in it's entirety yet.

Cosmic expansion only currently affects areas on the scale of megaparsecs, which is larger than galaxy clusters, since most smaller objects have sufficient internal binding energy to maintain their structure. So I don't believe we can do anything at all.

The expansion of space is accelerating and one day will affect the electromagnetic force (etc) if our theories are correct.

No, I'm saying we could manipulate the effect of dark energy on a section of space.
 
Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
3I/ATLAS, also known as C/2025 N1 (ATLAS) and formerly designated as A11pl3Z, is an iinterstellar comet. It was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile on 1 July 2025. Note: it was mentioned (as A11pl3Z) by DaveE in a new member's introductory thread. https://www.physicsforums.com/threads/brian-cox-lead-me-here.1081670/post-7274146 https://earthsky.org/space/new-interstellar-object-candidate-heading-toward-the-sun-a11pl3z/ One...
