A black hole is an object with such a strong gravitational field that even light cannot escape from its surface. A black hole may be formed when a massive object (very big object) undergoes uncontrolled contraction (a collapse) because of the inward pull of its own gravity. We shall now describe how the black holes are formed from neutron stars after the supernova explosions of big stars. When a supernova explosion of a very massive star takes place‚ then the gaseous matter present in the outer shell

Black holes do not exist—at least‚ not as we know them‚ says renowned physicist Stephen Hawking‚ potentially provoking a rethink of one of space’s most mysterious objects. A new study from Hawking also says that black holes may not possess "firewalls‚" destructive belts of radiation that some researchers have proposed would incinerate anything that passes through them but others scientists deem an impossibility. (Editor’s note: Watch for our feature "The Truth About Black Holes" in the March

“Holes” shows the importance of friendship in times of trouble and danger. Discuss ‘Holes’ by Louis Sachar is a phenomenal and superlative narrative. Entwining three remarkable stories from diverse generations and genres‚ Holes demonstrates immensely proficient writing dexterity‚ explicitly depicting the significance of earnest and genuine friendship in times of life’s trials and tribulations. This is exemplified when an averse and apprehensive Stanley and a despondent and barely conversant Zero

Black holes are a very interesting and fun topic to learn about! A black hole is a hole in space that sucks things in‚ not even light can get out. These holes pull forcely because stronge matter has been squeezed into a tiny space. Light can’t get out‚ so the human eye can not see them. Scientists use special equipment for seeing black holes. The tools can see how stars around the black hole act differently than the stars away from the black hole. Black holes were first discovered in 1916 by Karl

There are many common misconceptions about black holes whether it is that they destroy matter or that there is no way to ever escape a black hole. Black holes have this wrap on them that all matter that enters their event horizon is never coming out but‚ that can not be entirely true. The law of conservation states that no matter can be created or destroyed so‚ matter can not just be destroyed in black holes. In order to truly understand black holes one must first be able to understand event horizons

ever wondered what a black hole is? Many people think that black holes are dark‚ empty regions of space that suck in everything near them. But do you actually know what they are‚ how they are created‚ and everything you need to know to fully understand this topic? Well‚ if you don’t‚ keep reading to find out more. Black holes are stars that have compressed over time‚ making them very small‚ which causes them to have an extremely strong gravitational force1 and 3. Black holes are mainly made of nickel

Sacrificial Friendship In the book holes‚ written by Louis Sachar‚ Stanley Yelnats the main character is a poor‚ friendless‚ over weighted boy who is constantly bullied at school. He is arrest one day for a crime that did not commit. Stanley is therefore condemned to jail or to be sent to a place called Camp Green Lake for eighteen months as he is unable to prove his innocence. Stanley chooses Camp Green Lake. But upon arriving in the camp‚ Stanley discovers that it is actually a barren and desolate

will be speaking about an astronomical phenomenon called black holes. A black hole is an area of space-time. Rather‚ it is a great amount of matter packed into a very small region it is also the last evolutionary stage in the lifetimes of vast stars. This makes the black hole invisible to the rest of the universe‚ hence the word "black". A star‚ about 20 times the mass of the sun may produce a black hole at the end of its life. A black hole is formed by nuclear reactions in the core of a star producing

What are black holes? Black holes are places where gravity has become so strong that it overwhelms all other forces. Once something enters a black hole‚ nothing can escape its gravity‚ not even light. 2. How do scientists look for black holes in space? Describe what a black hole looks like using one of the different ways of seeing the sky? Scientists look for black holes in space using telescopes that pick up x-ray‚ visible light‚ and radio waves. Using an x-ray telescope‚ a black hole can be detected

Research Paper- Black Holes It’s really fun to keep observing with night sky with your naked eyes or a telescope. But have you ever thought that their might be bodies which could not be seen? Well let us think‚ what is Vision? When light is reflected or emitted by an object and it comes to our eyes‚ we can see that thing. According to the Interference phenomena and the Photoelectric Effect‚ light can be categorized as both a wave and particle. Also called as the Wave-Particle Duality of light
