Dark matter does not exist and the universe is 27 billion years old, study claims

A study from the University of Ottawa suggests we might not need dark matter or dark energy to explain the workings of the universe.

    This guy has been promoted for the last couple of months. He came up with a thought experiment, and he even says the thought experiment does not rule out dark matter.

    These articles are over hyping a non story.

    Science journalism is the reason I have to keep saying “no, quantum mechanics doesn’t do THAT”

    So “tired light” could explain redshift, light that loses energy over time, but where would that energy be going? Heat loss somehow? Energy can’t be destroyed according to our current understanding so I’m not sure I understand the mechanism of decay

      isn’t it the same with dark matter? There is no matter that cant interact with anything. We tried and tried in big and bigger Collider to find any trace of dark matter. I think scientist begin to find anything else that could explain the cosmos (even if it is flawed), because dark matter seems more and more unlikely, after all those year looking for it

        We’ve spent years and years eliminating the low hanging fruit – as one should do first – but that doesn’t resolve the dark matter problem at all. The more exotic types are really, really hard to detect in particle colliders the scale of which we can readily build.

        It would be nice to say “we looked for it, but it doesn’t seem to exist”, but we can’t say that. We’re nowhere close to saying that. Detecting particles that are hypothesized to only interact via gravity is insanely difficult.
