Do white holes exist?
White holes cannot exist, since they violate the second law of thermodynamics. General Relativity is time symmetric. It does not know about the second law of thermodynamics, and it does not know about which way cause and effect go.Can a wormhole exist?
In the early days of research on black holes, before they even had that name, physicists did not yet know if these bizarre objects existed in the real world.How cold is space?
The Cosmic Background Explorer (COBE) satellite has refined temperature measurements taken way back in 1964. According to data from the Cosmic Background Explorer (COBE) satellite, the temperature of space is 2.725K (2.725 degrees above absolute zero).What is the scariest thing found in space?
Halloween is a time to be haunted by ghosts, goblins and ghouls, but nothing in the universe is scarier than a black hole. Black holes – regions in space where gravity is so strong that nothing can escape – are a hot topic in the news these days.What does space smell like?
