No Big Bang? Quantum equation predicts universe has no beginning

The universe may have existed forever, according to a new model that applies quantum correction terms to complement Einstein’s theory of general relativity. The model may also account for dark matter and dark energy, resolving multiple problems at once. The widely accepted age of the universe, as estimated by general relativity, is 13.8 billion years. In the beginning, everything in existence is thought to have occupied a single infinitely dense point, or singularity. Only after this point began to expand in a "Big Bang" did the universe officially begin.Although the Big Bang singularity arises directly and unavoidably from the mathematics of general relativity, some scientists see it as problematic because the math can explain only what happened immediately after—not at or before—the singularity."The Big Bang singularity is the most serious problem of general relativity because the laws of physics appear to break down there," Ahmed Farag Ali at Benha University and the Zewail City of Science and Technology, both in Egypt, told Phys.org.Ali and coauthor Saurya Das at the University of Lethbridge in Alberta, Canada, have shown in a paper published in Physics Letters B that the Big Bang singularity can be resolved by their new model in which the universe has no beginning and no end.

One Of The World’s Top Aging Researchers Has A Pill To Keep You Feeling Young | Co.Exist | ideas + impact

Say someone came up to you selling a dietary supplement—a pill that you take once a day—that could boost your energy, improve your body’s ability to repair its DNA, and keep you healthier as you get older.

It might sound like a scam, or more likely just another in a sea of confusing, undifferentiated claims that make up the $20 billion dollar supplement industry.

But let’s say that someone is MIT’s Lenny Guarente, one of the world’s leading scientists in the field of aging research. And he’s being advised by five Nobel Prize winners and two dozen other top researchers in their fields. You might pay a little more attention.

How Would The World Change If We Found Extraterrestrial Life? – Astrobiology Magazine

HOW WOULD THE WORLD CHANGE IF WE FOUND EXTRATERRESTRIAL LIFE? By Elizabeth Howell – Jan 29, 2015The ALH84001 meteorite, which in a 1996 Science publication was speculated to be host to what could be ancient Martian fossils. That finding is still under dispute today. Credit: NASA/JSC/Stanford UniversityIn 1938, Orson Welles narrated a radio broadcast of “War of the Worlds” as a series of simulated radio bulletins of what was happening in real time as Martians arrived on our home planet. The broadcast is widely remembered for creating public panic, although to what extent is hotly debated today.Still, the incident serves as an illustration of what could happen when the first life beyond Earth is discovered. While scientists might be excited by the prospect, introducing the public, politicians and interest groups to the idea could take some time.How extraterrestrial life would change our world view is a research interest of Steven Dick, who just completed a term as the Baruch S. Blumberg NASA/Library of Congress Chair of Astrobiology. The chair is jointly sponsored by the NASA Astrobiology Program and the John W. Kluge Center, at the Library of Congress.Dick is a former astronomer and historian at the United States Naval Observatory, a past chief historian for NASA, and has published several books concerning the discovery of life beyond Earth. To Dick, even the discovery of microbes would be a profound shift for science.“If we found microbes, it would have an effect on science, especially biology, by universalizing biology,” he said. “We only have one case of biology on Earth. It’s all related. It’s all DNA-based. If we found an independent example on Mars or Europa, we have a chance of forming a universal biology.”
