A white hole is a strange cosmic entity that glows brightly and emits stuff rather than disappearing. To put it another way, it’s the polar opposite of a black hole. Unlike black holes, however, there is no agreement on whether white holes exist or how they develop. Einstein’s theory of gravity predicts them, and they’re most commonly cited in the… Read more →

Micro-gravity behaves as weightless for people or objects. When astronauts and objects float in space, the effects of Microgravity can be seen. In other ways, micro-gravity can also be experienced. Micro-gravity refers to the situation where gravity appears very small. “Micro-gravity” means “very small.” Astronauts will float in a micro-gravity on a spacewalk or outside. Easily shifting large objects. For… Read more →
