Variable Speed of Light Cosmology: An Alternative to Inflation

AI Thread Summary
Variable Speed of Light (VSL) theories are being explored, notably by researcher Joao Magueijo at Imperial College. The discussion highlights the potential for changes in the speed of light depending on the medium it travels through, suggesting that factors like "fine structure" could influence this. There is curiosity about how these concepts might apply to the fabric of space itself. Participants are encouraged to investigate Magueijo's work for deeper insights. The exploration of VSL as an alternative to inflation remains a niche yet intriguing area of cosmological research.

Does anyone know if VSL theories are being seriously researched, studied, and pursued?

I know of one guy called Joao Magueijo, who is working on this at Imperial College. I'm not particularly familiar with his work, but his webpage is at

if you want to check it out.

i can think of only one way the speed of light can change,
and that is whatever the light is traveling through, water, air,
it has been mentioned that BECs can stop light, so what can
change when light travels through space? i think its the
"fine structure", and if i remeber correctly if that changes
other things change.
 

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 'Can the signal WOW be explained by the maser effect?'

This hypothesis of scientists about the origin of the mysterious signal WOW seems plausible only on a superficial examination. In fact, such a strong coherent radiation requires a powerful initiating factor, and the hydrogen atoms in the cloud themselves must be in an overexcited state in order to respond instantly. If the density of the initiating radiation is insufficient, then the atoms of the cloud will not receive it at once, some will receive it earlier, and some later. But then there...
