How so? If you attribute it to an earlier universe, you are just pushing the problem further back. It doesn't seem to be a proof or even a mild indication.

  • The universe casually didn't follow the laws of physics immediately after the Big Bang, an improbable event directly after an improbable event. No explanation has been found, even according to CERN, why everything that was created was not spontaneously annihilated. Attributing that to a divine intervention is the most probable explanation. CERN attributing this to "Some unknown entity" is humorous.

    One theory (which CERN is using) is to argue that almost all matter was destroyed, and that the current observable universe is merely the tiny leftover due to slight differences in behavior, making the Big Bang look more like the Ludicrous Bang. This, of course, just contributes to religious snickering at how all problems are solved by adding another billion years to the timeline, over and over.

    Edit to reply: They behave differently; but why there is more of one than the other, remains unexplained; as regardless of how they behave, both should have been initially created in equal numbers. As for Sabine Hossenfelder's quote, that's a religious-faith level cop-out. When science requires faith, should it not be treated as a religion?

      Incorrect.

      First, let's be clear, "our understanding of the laws of physics" is not "the actual laws of physics". Every physicist knows this. The universe always follows the real laws, physicists are very excited about the difference because it's a chance to win a Nobel Prize.

      For example, the one in 1980 for the discovery (in 1964, they're slow to award the prize) of CP violation in decays of neutral kaons, which is fancy physics language for "matter and antimatter do not behave the same way". This year, the LHCb experiment in CERN also discovered CP violation in baryons.

      In fact, this is in your own linked article from CERN: """In the past few decades, particle-physics experiments have shown that the laws of nature do not apply equally to matter and antimatter. Physicists are keen to discover the reasons why."""

      That said, personally I like the response from Sabine Hossenfelder: There's nothing to be explained, conservation laws only apply to time-evolution of a system, not to the initial conditions.

      We don't look for a reason why the mass-energy was non-zero, why do we even need one for why the baryon number isn't zero?

    • > Attributing that to a divine intervention is the most probable explanation.

      You lost me here. It seems humans have a predisposition to believe in divine beings, so this just sounds like taking human biases as a basis for truth. What's wrong with saying, "I don't know?"
