An exotic theory, which attempts to unify the laws of physics by proposing the existence of an extra fourth spatial dimension, could be tested using a satellite to be launched in 2007. Such theories are notoriously difficult to test. But a new study suggests that such hidden dimensions could give rise to thousands of mini-black holes within our own solar system – and the theory could be tested within Pluto’s orbit in just a few years.
Spaceship travel to another universe through a black hole may be highly improbable, but it cannot be ruled out, according to a new analysis that explores the idea of "hybrid singularity."
Science fiction stories routinely conjure up black holes as portals for traveling across interstellar space. In reality, scientists say that's impossible. Or is it? New research suggests it could happen.
Supermassive black holes act like massive electric motors, generating untold amount of energy that is converted into magnetic fields that radiate up to ten million light-years into space. This power is what its discoverers say is the most dominant source of free energy in the universe.
