  1. > A new theoretical study suggests that the mysterious force driving the accelerated expansion of the universe—known as dark energy—may actually be rooted in a deeply quantum structure of space-time.

    > Since its surprise discovery in the late 1990s, dark energy has baffled researchers. Originally thought to be a constant vacuum energy spread throughout space, newer observations from the Dark Energy Spectroscopic Instrument (DESI) revealed that this acceleration may be slowing over time—a result the Standard Model of particle physics can’t explain.

    > That mystery led a team of physicists to explore a more radical solution: maybe dark energy isn’t just something filling space. Maybe it’s baked into the very nature of space and time itself. The team applied string theory to describe space-time not as a smooth continuum but as a quantum structure where the order of coordinates matters.

    > When modeled this way, space-time naturally gives rise to cosmic acceleration, and what could be crucial evidence of string theory is the data that suggests the acceleration decreases over time, **just as DESI data shows.**

    > If validated, this would represent the **first tangible evidence of string theory ever observed.** The theory has long been criticized for being mathematically elegant but experimentally unprovable. However, the research now connects the universe’s expansion rate to two extreme ends of the size spectrum: the minuscule Planck length and the vast scale of the cosmos.

    > The findings also suggest that the **core properties of the universe may not be constant after all**, hinting at a deeper connection between gravity and quantum mechanics.

    So they have a theory that aligns with current observations, but they can develop small experiments to corroborate.

  3. Just one more particle accelerator bro. String theory has been ”10 years away from proof” since the fucking 70’s. There’s always a new model, it gets headlines, and then it turns out that oh wait, we can’t actually test this. I don’t understand physics, but hyping string theory is the deadest horse physics has ever had.

  4. I’ve always felt the expansion of the universe was a matter of quantum properties.

    Not that there’s some anti gravity dark matter pushing at the galaxies, but rather that space itself is expanding into another higher dimensional super structure, after the “collision” that created the big bang.

    However this higher dimensional space time flows in the opposite direction, time is opposite there, and because of that property the expansion is increasing rather than decreasing.

    Which explains the singularity of black holes. As they break the “canvas” of our space time into this higher dimension, time flows opposite, and so it slows down the close you get to it. Or just the more mass “weighs” on this “canvas”.

  5. String theory. I forget which (probably many) physicist said it, but it was basically string theory is a very cheap project. All you have to pay for are the scientists in a room to put them in.
    So despite it not seeming to make any advances at all, at least it’s cheap!

  6. String theory is absolutely trash and it wasted an entire generation of scientists and funding
