Call it a follow-up question to a beyond-the-grave debate: Albert Einstein theorized that black holes can only grow. Stephen Hawking postulated that they can decay. After a group of scientists published a paper supporting Team Hawking, inquiring minds wanted to know how long before the Universe itself completely fades away.The answer, according to an article in the Journal of Cosmology and Astroparticle Physics, is a “1” followed by 78 zeroes and the word “years.” That is much faster tha ...read more

Researchers now say the weapons date back closer to 200,000 years, rather than the 300,000 years to 400,000 years of earlier estimates, according to an article in Science Advances.Neanderthal and Early Man AncestorsThis has important implications t ...read more
The title for World’s Oldest Dog goes to Bluey, the Australian cattle dog, who reportedly lived to the grand old age of 29. However, the average life expectancy for most canines is a relatively meagre 10 to 13 years. So, why is it that the lifespan of a dog is so much lower than that of species like the rhino, which can live up to 50 years?The lifespans of mammals vary dramatically, from species of shrew that don’t make it to their first birthday to the bowhead whale, which celebrates two ce ...read more
