White holes would be even stranger than black holes. They would still have singularities at their centers and event horizons at their borders. They would still be massive, gravitating objects.

White holes are theoretical cosmic regions that are opposite to black holes. Just as nothing can escape a black hole, nothing can enter a white hole.

At the moment, white holes are theoretical mathematical concepts that astrophysicists use to help further study black holes in space. To study a black hole, scientists mathematically explore the ...

The major difference between black holes and white holes is their formation. We know, thanks to the work of J. Robert Oppenheimer and collaborators, that when a massive star undergoes a complete ...

White Holes, like Rovelli's other works, is remarkably short — less than 200 pages. But the clarity of his explanations is unparalleled. As a scientist who is also a popularizer, ...

White holes are like cosmic one-way fountains, hypothetically vomiting out energy and matter while refusing to let anything in. But so far, they exist only in equations and sci-fi dreams, ...

White holes, like their black hole counterparts, have been studied for some time and are legitimate solutions to Einstein’s field equations. In simple terms, a white hole is the time-reversed ...

Of course, white holes are not a new idea, and were first proposed way back in the 1930s. But what little we know about black holes the same can be doubly said for white holes.

Unfortunately, no evidence supports his claims, but there is still hope that one day scientists could bump into it. White holes would defy several established physics principles, which is one reason ...

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.
