Sound waves fossilized in the maps of galaxies across the Universe could be interpreted as signs of a Big Bang that took place 13 billion years earlier than current models suggest. Last year, theoretical physicist Rajendra Gupta from the University of Ottawa in Canada published a rather extraordinary proposal that the Universe's currently accepted age is a trick of the light, one that masks its truly ancient state while also ridding us of the need to explain hidden forces. Gupta's latest analysis suggests oscillations…

Every night, I—like millions of others—put on a noise machine to help me sleep. Mine offers several types of noise: white, pink, green, and brown. I’ve noticed something strange, though. After about 30 minutes of the noise pumping into my head, I start to hear things. Sometimes it’s music, like a full orchestral score. Other times it’s people having a conversation just out of the range where I’d hear actual words. Occasionally, it sounds like my husband playing a video game.So I do what most people would do when a random…

A nearby exploding star is due to offer a spectacular show that could outshine our North Star this year.The star, which is 3,000 light-years from Earth, is expected to burst in a gigantic explosion – known as a nova – in the coming months. NASA said in a statement that the once-a-lifetime event could be so big that it can be seen by the naked eye. It should be visible for up to a week. It will be "fun and exciting upcoming cataclysm," Bradley Schaefer, an astrophysicist at Louisiana State University, told The New York…

A group of infectious disease specialists published an article in JAMA advocating for increased awareness and preparedness in the medical field to address the evolving threat of diseases due to climate change. They emphasize the need for updated medical training and proactive measures to mitigate global warming’s impact on health.

SpaceX is reportedly eyeing a quick turnaround for its fourth Starship launch. Following a very successful third launch earlier this month, SpaceX seems keen on a May launch date for Starship’s fourth iteration, according to some reports.The news first broke during the Satellite 2024 conference on March 19, when Gynne Shotwell, the president and chief operating officer at Space, said that the company was still reviewing the data gathered from Starship’s third launch but that it would be ready to launch another…

The world of robotics has seen a number of advancements in recent years. The work coming out of companies like Boston Dynamics continues to be exciting, and we’ve even seen the development of more humanoid robots like China’s H1. Now, though, the robots are starting to break the robot speed records set for them by earlier models, putting them one step closer to matching humanity’s capabilities.Of course, I could sit here and spend this entire article droning on and on about the future of robotics and how robots…

Researchers at Tokyo Tech identify the quantum critical point in superconductors, solving a three-decade-old mystery and enhancing the understanding of superconductivity fluctuations. Credit: SciTechDaily.comThermoelectric effect reveals full picture of fluctuations in superconductivity.Weak fluctuations in superconductivity, a precursor phenomenon to superconductivity, have been successfully detected by a research group at Tokyo Institute of Technology (Tokyo Tech). This breakthrough was achieved by measuring the…

Our love for coffee means millions of tons of spent coffee grounds going to waste every single year. Scientists have been working on ways to make use of them, and we now have another to add to the list: old coffee grounds have been shown to absorb bentazone, a herbicide used in agriculture. If the technology can be developed, it would solve two environmental problems in one: coffee ground waste, and damage caused by farming herbicides to wildlife and the surrounding natural world. A team from the Federal Technological…

Scientists have created the largest ever supermassive black hole map. The map, which is featured in a paper in The Astrophysical Journal, showcases more than 1.3 million quasars found in space and time. The furthest black hole featured in the map existed when the universe was only 1.5 billion years old, over 12 billion years ago.The map itself is showcased in a video within the paper, and it’s somewhat terrifying to think of all those supermassive black holes bounding their way through our universe, including…
