They found galaxy looking older then the Universe - with 4.7 sigma for JADES-1050323.
So could galaxy survive Big Bounce?

Old galaxies in a young universe?
The standard cosmological model (present-day version of "Big Bang," called Lambda-CDM) gives an age of the universe close to 13.8 billion years and much younger when we explore the universe at high-re...

Chrome 145 (current) has started support of JPEG XL long-term JPEG successor, which should soon replace JPG, PNG, GIF - greatly reducing size and improving quality of our images and photos. Firefox and PDF are next.

Google Chrome 145 Released With JPEG-XL Image Support
Back in 2022 Google deprecated and then removed JPEG-XL image support from the Chrome/Chromium browser codebase and now in 2026 it's back

While for classical computers we can push&pull electrons through a chip: have two-way control(2W), for quantum there is only focus on 1WQC.
Reaching 2WQC ( www.qaif.org/2wqc ), in theory they could solve NP problems, have better error correction...requiring PQC resistant to NP-solvers.

LIGO might soon turn out even more interesting - as there was observed only 1 (retarded) EM counterpart per ~400 events, and mathematically also advanced solutions are allowed.
More arguments e.g. "too early events", missing SMBHs for PTA (if only retarded): arxiv.org/pdf/2512.20692
