FAQs about Cosmic Mysteries

Some of the biggest cosmic mysteries include the true nature of dark matter and dark energy, what happens inside a black hole, how the universe began before the Big Bang, and whether or not we are alone in the universe.

A black hole is an object in space with a gravitational pull so strong that nothing, not even light, can escape it. They are formed from the collapsed remnants of massive stars and can grow by absorbing stars and other black holes.

Dark matter is an invisible, mysterious substance that does not emit or reflect any light. We know it exists because of its gravitational effects on visible matter; the rotation of galaxies and the bending of light around them would not be possible without the extra mass that dark matter provides.

Scientists use a combination of powerful telescopes to observe the effects of these mysteries, particle accelerators like the Large Hadron Collider to search for new particles, and complex computer simulations to test their theories against the laws of physics.
