Interstellar Travel: Theorical Force to Stabilize Wormhole

AI Thread Summary
The discussion centers on the theoretical forces that could stabilize a wormhole, particularly the role of "exotic matter" that exerts an outward push on the wormhole's walls. This concept is likened to Einstein's cosmological constant, with the distinction that exotic matter would possess negative energy. However, the feasibility of gathering sufficient exotic matter poses significant challenges. The existence of wormholes remains speculative and dependent on certain assumptions of General Relativity. Experimental confirmation of wormholes is likely far off, especially if future physics advancements alter current theories.

Theorically speaking, what force could stabilize a wormhole?
 
Astronomy news on Phys.org
if wormholes were not empty and contained a small amount of matter, "exotic matter" that could exert an outward push on its walls then it might be possible to keep a wormhole open. it is similar to einstein's cosmological constant but the exotic matter would have a negative energy assosiated with it. BUT gathering so much exotic matter would be VERY difficult.
 
Welcome to Physics Forums, lucasm1!

"Wormholes" are purely speculative concepts which seem to be possible under certain assumptions of General Relativity.

Experimental or observational confirmation of even the existence of such critters is still many lifetimes away (assuming advances in physics theory don't rule them out beforehand, e.g. from some discovery in M-Theory).
 

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?'

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...
