Lots of debit regarding Black Holes and Wormholes present. Many scientists have not accepted these theories. Black Holes is a region of space in which the gravitational field is so powerful that nothing, including electromagnetic radiation such as visible light, can escape its attraction, a kind of bottomless pit in space-time. Wormholes theory tells about space-time. If space-time created we take a long journey around this universe through shortcuts.
we can observe in our sky- planets, stars, gas, dust, galaxies, nebulae, asteroids, meteors, and more-is a small fraction of what exists. Bright matter, the visible stuff of the universe, forms only about a sixth of its mass. What forms the rest, and how do we know it’s there?
Scientist View on Black Holes and Wormholes
Scientists know there must be more out there than meets the eye because the unseen substance has gravity and appears to be holding together the parts of the universe that we can see, galaxies in particular. Because the un-seen matter does not emit radiation. scientists call it dark matter. Believed to constitute about 95 per-cent of the universe’s total mass, dark matter and dark energy may comprise
unfathomable numbers of tiny sub- atomic particles. Candidates for dark matter include cold dark matter (CDM), sluggish elementary particles; weakly interacting massive particles (WIMPS), heavy hypothetical particles that rarely interact with other matter; and massive compact halo objects (MACHOS), known objects such as planets, neutron stars, and white dwarfs that are presumed to be in the halos of galaxies.
About Black Holes:
A black hole forms when a large, dying star collapses. The gravity created by this condensing matter completely overpowers any outward forces, including light. Although a black hole emits no light, its presence is detectable by radio astronomy equipment. Its extremely strong gravitational pull
sucks gas and dust toward itself, forming a whirling accretion disk around the hole. The disk heats any matter that crosses it, emitting x-rays (opposite).
STEPHEN HAWKING/ASTROPHYSICS VISIONARY
Appropriately enough, British theoretical physicist Stephen W. Hawking (b. 1942) was born on the 300th anniversary of the death of Galileo. Since 1979 Hawking has held the chair in mathematics at Cambridge University once held by Isaac Newton, Hawking studies basic questions of the origins, nature, and future of the universe, and he seeks a unified theory able to reconcile Einstein’s general theory of relativity and quantum theory. Early in his career, at age 21, Hawking was struck with amyotrophic lateral sclerosis (ALS)a degenerative neuromuscular disorder commonly known as Lou Gehrig’s disease. Despite his ALS, he remains vitally invested in his work, sharing ideas with scientists and the public through books, on the Internet, and on television.
WHAT IS A WORMHOLE?
A highly speculative idea of modern astrophysics, wormholes are theoretical possibilities allowed within the mathematical framework of Einstein’s general theory of relativity. A worm hole is a short-lived portal, lasting only a brief moment, that joins two black holes in different locations. Wormholes could connect two points in the present-day universe or perhaps, in different times. In worm- hole theory, matter falling into a black
hole at one point should emerge through a proposed “white hole”- the reverse of black hole-at the other end. Neither wormholes nor any evidence of them has yet been observed. Scientists cannot determine how they would be created, although astrophysicists such as Hawking continue to work on this intriguing notion.
