'The chances of you living 50 years are very small': Theoretical physicist explains why humanity likely won't survive to see all the forces unified - Live Science

The ROSES-25 program element  D.4 Theoretical and Computational Astrophysics Networks (TCAN) supports coordinated efforts in fundamental theory and computational techniques to make advances in astrophysics that extend beyond the scope of individual investigator projects. The goals of the TCAN program include strengthening theoretical and computational astrophysics in the United States by uniting researchers in collaborative networks that cross institutional and geographical boundaries and advance the training of the future workforce of theoretical and computational scientists. For this program element, the TCAN program focuses its scope on grand challenges in Time Domain Multi-Messenger Astrophysics, and solicits proposals aimed at developing integrated theoretical and computational tools for modeling multi-messenger phenomena through collaborative networks.

For physicist Reina Maruyama, the 2026 Nobel Prize in physics brought back warm memories of cold moments. The prize, awarded earlier this week, went to Francis Halzen of the University of Wisconsin-Madison, the principal investigator for the groundbreaking neutrino experiment IceCube, which is based at the South Pole. Launched officially in 1999 with an ambitious experiment proposal, the IceCube Neutrino Observatory, located deep beneath an ice sheet near the Amundsen-Scott South Pole Station in Antarctica, would go on to discover high-energy neutrinos that originate in deep space and travel unimpeded through the universe. The experiment grew to include more than 450 researchers from 58 institutions in 14 countries. The IceCube Neutrino Observatory was completed in December 2010, ahead of schedule. Physicist Reina Maruyama, a member of the collaboration, is shown helping to hold the celebration banner.

Tech billionaires attempting to live for ever are, quite literally, wasting their time, a leading physicist has said. While some normal people are turning to unregulated peptide injections, cold plunges and supplements in an effort to defy ageing, the ultra-rich are aiming for immortality with even more drastic interventions: the tech chief executive Bryan Johnson has even tried injecting plasma from his 17-year-old son – although he later said he saw no benefit from it. Bryan Johnson (and son Talmage) is the world's most measured human.

And the more I study the nature of time, the more I think about it, the more I realise that I just want to make the most of the time that I have,” he said. “We’re [here for] a blink of an eye compared with the age of the universe.
