Creepy Facts About Outer Space You Can't Unlearn

Like Superman's alter-ego, Bizzaro, the particles making up normal matter also have opposite versions of themselves. An electron has a negative charge, for example, but its antimatter equivalent, the positron, is positive. Some futuristic spacecraft designs incorporate anti-matter engines. If a radical new "braneworld" theory of gravity is correct, then scattered throughout our solar system are thousands of tiny black holes, each about the size of an atomic nucleus. Unlike their larger brethren, these mini-black holes are primordial leftovers from the Big Bang and affect space-time differently because of their close association with a fifth dimension. Also known as the CMB, this radiation is a primordial leftover from the Big Bang that birthed the universe.
Mysterious Radio Signals
Jeff Johnson , Updated June 17, The universe can be a very strange place.
If you would like to be involved in its development let us know. Think spooky phenomena and you might think of ghosts, ghouls and other things that go bump in the night. But forget Edgar Allen Poe, for creepy tales of the unexplained you need look no further than your nearest physics textbook. We have plenty of evidence that dark matter exists, but as for what it is, that remains a mystery. Whilst dark matter appears to mesh galaxies together, dark energy seems to want to push everything apart. Quantum entanglement is a bit of a nuisance for classical physics, because it breaks some fundamental laws that we previously thought unbreakable.
Really big. Truer words have never been spoken. In fact, the universe is so big that its size and scope is nearly incomprehensible, even to the most knowledgeable and open-minded individuals. Many of them are actually a collection of objects held together by the immense force of gravity. Just so you have an idea of the kind of scales that we are talking about, light travels at , kilometers , miles per second, which equals out to 5,,,, miles 9,,,, km each year. Our galaxy, the Milky Way, is so long, it would take light more than , years of traveling to cross it.
There's no questioning the fact that the universe is weird. Just look outside and you'll see all manner of strange, self-reproducing flora and fauna, crawling upon a blue ball of semimolten rock covered in a thin, hard shell and blanketed by a tenuous film of gases. Yet our own planet represents a tiny fraction of the peculiar phenomena that can be found lurking throughout the cosmos, and every day astronomers turn up new surprises. In this gallery, we take a look at some of the most outlandish objects in space. Since , researchers have been receiving ultrastrong, ultrabright radio signals lasting only a few milliseconds.
