A groundbreaking study by researchers from the University of Toronto, has revealed a phenomenon where photons were seen exiting a material before they entered it. This observation, marking the first evidence of negative time, was made during an experiment involving atomic excitation. The team has been investigating this light-matter interaction for seven years.
In 4 billion years, when the Milky Way galaxy collides with the Andromeda Galaxy, the distance between the stars will be so vast that none of the 1.3 trillion stars are expected to collide.
In roughly 4 billion years, the Andromeda Galaxy and the Milky Way will collide, creating a new supergalaxy. This galactic merger will not result in stars colliding due to the vast distances between them, but the supermassive black holes at the centres of both galaxies will eventually merge. While the solar system might get flung farther from the galactic core, there’s also a chance it could be ejected entirely. Even though life on Earth would have ended by then due to the Sun’s increasing heat, this cosmic event would offer a stunning view of the changing night sky.

It’s the disruption to the normal gravitational systems and orbital paths. A planet that was in the goldilocks zone for liquid water and life could get affected by another passing star system enough to move it sufficiently out of its normal orbit to have planet changing effects.”

As NASA advances the Artemis II mission, significant strides are being made with the mobile launcher at Kennedy Space Center.
Recently moved back to the Vehicle Assembly Building after undergoing extensive testing and upgrades, the launcher is central to launching the next Moon rocket. Alongside, the crawler-transporter marked a historical milestone, reaching over 2,500 miles since its inception, reinforcing its title as the heaviest self-powered vehicle by Guinness World Records.

Scientists have discovered that cosmic filaments, the largest known structures in the universe, are rotating. These massive, twisting filaments of dark matter and galaxies stretch across hundreds of millions of light-years and play a crucial role in channeling matter to galaxy clusters. The finding challenges existing theories, as it was previously believed that rotation could not occur on such large scales. The research was confirmed through both computer simulations and real-world data, and it opens up new questions about how these giant structures acquire their spin.
After reading the article, a Reddit user named Kane gained more than 100 upvotes with this comment: “What if galaxy clusters are like neuron and glial clusters in a brain. And dark matter is basically the equivalent of a synapse. It connects galaxies and matter together and is responsible for sending quantum information back and forth like a signal chain.”

The German scientist argues that information cannot be destroyed and, in principle, it is possible that a higher being, one day, in some way, could reassemble it and bring it back to life.
