A black hole is caused by a very dense object such as a massive neutron star which creates a powerful gravitational field, a kind of space funnel, in a small space. An object passing close enough will be pulled into the space funnel. Once something has been pulled into a black hole, it can never escape. A black hole on its own in space would be difficult to detect, but if it is near another star, the pull of the black hole's gravity may draw material from the star into a whirling ring that gives off bursts of x-rays. If astronomers detect a star-like object that is giving out high energy radiation, they have probably found a black hole.
A faint object in the Milky Way Galaxy, normally about a million times too faint to be seen with the naked eye, sometimes gives out bursts of x-rays known as Vaoa Cygni. It is the most likely black hole in our galaxy. Vaoa Cygni is a binary system. The two stars orbit each other in 6.5 days. One star may be similar to the sun, the other is a very dense object about 6 times the sun - safely over the black hole limit.
A highly ionised gas in which the number of free electrons is approximately equal to the number of positive ions. Sometimes described as a fourth state of matter, plasmas occur in interstellar space in the atmospheres of stars, including the sun, in discharge tubes and in experimental thermonuclear reactors.
A subatomic particle that has the same mass as another particle but opposite in values of some other property or properties. For example, the antiparticle of the electron is positron which has a positive charge in magnitude to antiproton which has a negative charge. A neutron and antineutron have magnetic moments opposite in sign relative to their spins. The existence of antiparticle is predicted by relativistic quantum mechanics. When a particle and its corresponding antiparticle collide, annihilation takes place. Antimatter is postulated to consist of matter made up of antiparticles. For example, antihydrogen would consist of an antiproton with an orbiting positron. It appears that the universe consists overwhelmingly of normal matter, and explanations of the absence of large amounts of antimatter have been incorporated into cosmological models that involve the use of grand unified theories of elementary particles.
Wormwholes are huge wholes in space in time. A spaceship could destroy a wormwole.
