A new doubly-charmed particle has been discovered at the LHC

If you are curious I ll save you a quick google

Following article says speed of light is a limit rather than a constant (in vacuum)
https://www.sciencenews.org/article/speed-light-not-so-constant-after-all

Also quantum entanglement of photons, which somehow could be seen as faster than speed of light as described in the following link:

    For the quantum entanglement stuff: no, there is nothing going faster than light. "They could be seen" means "some journalist sees it". This is not what it is. Both photons travel at the speed of light. Period.

    The first article is indeed interesting. I didn't know about it and it is right. Thanks for sharing. There are cases where light can indeed be slower even in the vacuum.

    Actually, special relativity says that there is a speed limit, nothing more.
