    I Am An Astrophysicist. Here’s What Stephen Hawking’s Final Paper Was Actually About
    quote: it isn’t the end of the Universe, and it’s not likely to lead to new evidence for the Multiverse, either

    ... His final paper, entitled A Smooth Exit from Eternal Inflation? (preprint here), focuses on the birth of the Universe as we know it. Regardless of how it all turns out, these fundamental questions will continue to delight, puzzle, and frustrate physicists as we search for the ultimate answers to the true nature of the Universe itself.

    The 4 Scientific Lessons Stephen Hawking Never Learned

    ... Despite his incredible successes in a number of arenas, there are some major scientific lessons he never learned. Here’s your chance to learn them now:

    1.) We still don’t know whether black holes destroy information ...

    Only Dark Matter (And Not Modified Gravity) Can Explain The Universe
    There have been a lot of public advocates from the “no dark matter” camp, getting lots of popular attention. But the Universe still needs dark matter. Here’s why

    ... Two solutions spring to mind: either there’s some type of unseen mass out there making up the deficit, or we need to modify the laws of gravity, as we did when we leapt from Newton to Einstein. While both of these possibilities seem reasonable, the unseen mass explanation, known as dark matter, is far and away the superior option.

    Individual galaxies could, in principle, be explained by either dark matter or a modification to gravity, but they are not the best evidence we have for what the Universe is made of, or how it got to be the way it is today.(Stefania.deluca of Wikimedia Commons)

    Scientific Proof Is A Myth

    The Bullet Cluster Proves Dark Matter Exists, But Not For The Reason Most Physicists Think

    ... Interestingly, this argument has been made for over a decade, now, with no satisfactory counterargument coming from detractors of dark matter; it isn’t the displacement of gravitation from normal matter that “proves” dark matter exists, but rather the fact that the displacement only occurs in environments where dark matter and normal matter would be separated by astrophysical processes. This is a fundamental issue that must be addressed, if alternatives to dark matter are to be taken seriously as complete theories, rather than ideas in their infancy, that time is not yet at hand ...

    ... The conclusion was inescapable: the hot Big Bang definitely happened, but doesn’t extend to go all the way back to an arbitrarily hot and dense state. Instead, the very early Universe underwent a period of time where all of the energy that would go into the matter and radiation present today was instead bound up in the fabric of space itself ...

    Science uncovers the origin of the first light in the Universe
    ‘Let there be light’ isn’t just biblical. It’s science


    ... After centuries of investigating the origins of the Universe, science has finally uncovered what physically happened to “let there be light” in space.

    ... So where did this light — the first light in the Universe — first come from? It didn’t come from stars, because it predates the stars; in the beginning, there was exponentially expanding space, and it was the end of that epoch — the end of cosmic inflation — that gave rise to the matter, antimatter, and radiation that would give rise to the first light we can see in the Universe ...
