New research suggests black holes may transition into 'white holes', ejecting matter and potentially even time back into the universe, defying our current understanding of these cosmic giants. New ...

Here’s what you’ll learn when you read this story: Theoretical physicists have long debated the possible existence of wormholes, which are mathematically possible, but no evidence points to their ...
