Expansion of the universe may be an illusion, new study claims

Scientists have long believed that the universe is expanding, but what if it isn't ?
Back in 1929, Edwin Hubble - the man after which the Hubble Space Telescope is named - observationally confirmed that the universe is not static but is in fact constantly expanding.

More recently, observations by modern telescopes have indicated that the universe isn't just expanding but is actually doing so at an ever accelerating rate.

The mysteries of the cosmos are compounded further still by dark energy and dark matter - two concepts that remain unproven and for which we have never found any actual direct evidence.

But what if there was another explanation for what scientists have been observing all these years ?
In a new study, University of Geneva professor of theoretical physics Lucas Lombriser has put forward a controversial new theory that would totally upend everything we think we know about the universe.

In it, Lombriser proposes that the universe isn't expanding at all and that, instead, the effects we observe are due to the evolution of the masses of particles (such as protons and electrons) over time.

The specifics of his theory are fairly complex, but they do also negate the need for dark energy and dark matter, which means that it could help to resolve a lot of outstanding issues in modern cosmology.

As things stand, however, there is no way to confirm that his theory is correct.

They should call it the Big makin' more room in da Unie. perchance.

sci fi thought but when something expands there is usually some pressure from within that pushes out? or are the stars and the galaxies pushing out? I'm not a big fan of how they observe things and make up a whim like the big bang. Can't teach an old dog new tricks I guess.

I like to think of it as another one of those current mysteries that will make perfect sense when we "wake from the dream"

I don't understand much of it but I thought (always dangerous for me) that was the role dark energy played.

I learned that when you tunr on a T.V. and watch the white noise that you can detect evidence for the BIg Bang?!? It infuriates me to hear about the big bang anymore, the scientists who ride on it are offensive. I feel a lot of wrath about it.

Wouldn't it be great if this theory is correct. It would probably mean that the universe will regenerate itself and not end up as a black nothing.

Why is the Sky Dark at Night Basic premise is that in a stable non-expanding universe a dark sky isn't possible. I ran across this website about 20 years ago as I had downloaded his HTML editor Archnophilia. Author is Paul Lutus https://arachnoid.com/administration/index.html https://arachnoid.com/sky/index.html But I wonder if Black Holes can act as energy sinks that prevent a non-expanding universe from reaching equilibrium. There are several pages to this and navigation is by small purple arrows at the bottom of the page.

I once read a joke about it, and it went something like this: A feminist and a male astrophysicist had a chat. She said, "O, how typically male chauvenistic to call the start of the universe the "Big Bang"! "What else? You think it started with a headache?", the astrophysicist replied.

I dunno if ‘they’ are certain if our universe is finite  or  infinite?    If ours is finite ,there Is a limited amount of universe in it, which might re-cycle? .. expand ,and contract, over and over?      And,,,there might be an Infinite? number of such closed systems within a Multi- Verse..which also recreates in the process.     That idea would allow for beginnings and ends of local finite universes ..with nothing actually Lost in the infinite Multiverse.     ??    Nature likes Circles. ..maybe any sort of warp is eventually a circle?       I ran across an idea about m...

If the universe is an atom, and we orbit the nucleus, and that atom belongs to a grander universe that has a nucleus, and that nucleus belongs to a bigger universe, then you have the same laws of nature functioning at precise ratio's to change in density/background temp of the universe for infinity.
