Study: Dark matter does not exist and the universe is 27 billion years old
The fabric of the cosmos, as we understand it, comprises three primary components: 'normal matter,' 'dark energy,' and 'dark matter.'
Heh
You're viewing a single thread.
This model explores the notion that the forces of nature diminish over cosmic time and that light loses energy over vast distances
Losing energy.. to what?
You try being a bright ray of sunshine for everything around you all day every day. Sometimes you just get tired, ya know?
Wildass hypothesis I just pulled out of my ass with an undergraduate degree in applied physics: maybe interaction with particles emerging from quantum vacuum?
Okay, that sounds like great technobabble. I'm going to watch star trek now ;)
Seems you may be on to something. Virtual particle interactions seems to be a hypothesis for tired light.
To test this I suggest we reprogram the deflector dish to emit a low-power tachyon pulse to see if we can excite the non-baryonic mass interactions.
Don't forget to reverse the polarity of the neutron flow!
Shit, if only my turbo encabulator wasn't broken!
those are old tech.
obsolete even.
You sound like you know what you're talking about. I'm taking notes. 📝🧐
It's those damn inertial dampeners again
To the dark matter, of course.
;)
This doesn’t answer the question in the context of this theory, but the current understanding is that light does lose energy as it travels through expanding space. As the space it’s in expands, the wavelength gets longer, and the energy goes down. It doesn’t go anywhere; energy just isn’t conserved in an expanding space-time.
If the light loses energy, then it must surely lose it to something? And if your last point that energy isn't being conserved in our universe, in which case we are either in some deep shit with the first law of thermodynamics, or our universe isn't an isolated system.
Seems energy is not conserved.

The thing about photons is that they redshift, losing energy as space expands. If we keep track of a certain fixed number of photons, the number stays constant while the energy per photon decreases, so the total energy decreases.
Ok. Smarter people probably thought of this, and probably found my hypothesis to be impossible. But what if... It is the the other way around. What if photons are losing energy because they are expanding spacetime. Like tiny little springs expanding out.
Further into the article he says that, "It would be irresponsible of me not to mention that plenty of experts in cosmology or GR would not put it in these terms. We all agree on the science; there are just divergent views on what words to attach to the science. In particular, a lot of folks would want to say “energy is conserved in general relativity, it’s just that you have to include the energy of the gravitational field along with the energy of matter and radiation and so on.” "
So energy is conserved on the whole, it's just not conserved if you consider photons apart from their greater context.
The energy is actually not conserved across the universe in general relativity, as it is currently understood. Conversation of energy is due to the time symmetry, which the expansion of space breaks.
“Energy is conserved in general relativity, it’s just that you have to include the energy of the gravitational field along with the energy of matter and radiation and so on.”

BTW, thanks! This comment sent me down a fascinating rabbit hole. It had simply never occurred to me that energy conversation didn't apply in an expanding universe!
It's probably not that the light is losing energy it's just that the distance it travels over time (the time we "know" is supposed to take for a given distance) appears compressed because of unknown/unseen gravitational forces.
Think of it like this: If there were only one star in the universe and it emits a particle of light we could calculate the distance it would travel over time. Yet we know that star will still have a gravitational effect on that light... No matter how far away it gets.
That's what they mean by light "losing energy". Is the energy actually "lost"? Not really. Is this slowing (aka appearance of lost energy) caused by dark energy/dark matter or something more fundamental like spacetime itself being stretched or compressed due to the gravity of astronomical objects we can see or "dark matter"/"dark energy" or... ? We don't really know for certain yet!

This doesn't seem to be at all what tired light proposes though. What you're explaining sounds like red-shift due to an expanding universe. From what I can tell they claim it actually loses energy through interaction with "other things" in the universe.
Entropy, capital "E".
