    Dark Energy Might Not Exist After All
    Sabine Hossenfelder, Backreaction

    . . . What they found is that the best fit to the data is that the redshift of supernovae is not the same in all directions, but that it depends on the direction. This direction is aligned with the direction in which we move through the cosmic microwave background. And – most importantly – you do not need further redshift to explain the observations. . . .

    This paper, I have to emphasize, has been peer reviewed, is published in a high quality journal, and the analysis meets the current scientific standard of the field. It is not a result that can be easily dismissed and it deserves to be taken very seriously, especially because it calls into question a Nobel Prize winning discovery. This analysis has of course to be checked by other groups and I am sure we will hear about this again, so stay tuned.
    With the new discovery of these super mega massive black holes. it is possible for neither dark energy nor dark matter to exist.
    gravity is enough to keep galaxies together and with all of these super dense black holes that would give a good indication that dark matter
    is no longer needed either.

    There was an indian professor that came up with a theory a while ago that said the same thing.

    That's what makes it so much better than ideas based on faith, such as creationism and flat earth, or religion. No matter how much evidence to the contrary is presented, those people just keep on believing
    science does not negate faith or religion.
    There are things that science can and will never be able to explain.
    they can theorize but that is about it.

    PS scientist do the same thing you accuse other people of doing.

    I agree. Science simply doesn't need it. Science and religion are incommensurate.

    This thread shows how cutting edge astronomy is. I'm amazed at how different our knowledge of the universe is today than back when I was a kid, rooting for the Apollo astronauts. Every decade brings more discoveries and more questions and problems. I read about the current theories of the "multiverse" and my head explodes.
    Dark energy and matter no doubt have major revisions ahead, and may indeed be overturned by some totally new approach to explain the weird data we keep turning up. It could be revolutionary, a la Thomas Kuhn. If so, I just hope it's within my lifetime.
