During the Sturtian glacial period during the Neoproterozoic Era, Earth underwent periods of global glaciation, which have been described as either "Snowball" and "Slushball" Earth scenarios. In Snowball Earth models, the planet was completely covered in ice for around 56 million years. In the Slushball models, portions of thin or patchy ice or even open water still existed in the tropics. However, there are some inconsistencies between these models and geological and biological evidence.
"Did you know a black hole is formed when 3 million suns collapse?
A massive star collapses, crushing its atoms into a singularity, creating an intense gravitational pull. Nothing escapes once inside.
"You are not alone, you are part of something much bigger than this universe."
What's your craziest black hole-related theory?
Gold and other heavy elements are born in some of the universe’s most violent events—but scientists still struggle to understand the nuclear steps that create them. Now, nuclear physicists have uncovered three key discoveries about how unstable atomic nuclei decay during the rapid neutron-capture process, the chain reaction responsible for forging elements like gold and platinum.
