Have you 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

Humans have always had a fascination with flying since the beginning of time. Hot air balloons were invented in 1783‚ one step closer to the airplane. The balloon is filled with hot air‚ which makes the balloon fly to the air because hot air is lighter than cool air. The only problem with the hot air balloon was that you could not control the direction it was going. The first airplane was actually a glider. This aircraft was launched from a cliff or from any high place. It rode on the wind

(AstroLab.2006) after he became an “Astroseismologist” which is an Astronomer who studies the internal structure of stars meaning to study the parts inside of the stars‚ by looking at changes in their light. Gilles Fontaine has won many awards like the BSC Physics award at Laval University in 1969 and the Marie-Victorian

Technology in the 21st Century Thulitoots n-cube Technology occupies an important role in the 21st century. Modern advancements have made life on earth much easier for the human race. In the last one-hundred years‚ progress in astrophysics has resulted in man’s ability to give an approximation of the age of the universe. Advances in the medical sciences have extended the average life-span‚ and increased the general well-being of humans in industrialized nations. For these reasons‚ I posit the

Astronomy: The discovery of Uranus What was the motivation that led to the discovery? The motivation that led to this discovery was simply that the Universe was so big. Herschel knew that there had to be more out there than what has already been discovered. He made the effort to study the universe and came across what he thought was a comet‚ but ended up being planet Uranus. What questions were asked? There weren’t as many questions asked as a normal scientific discovery since it is claimed that

Accordingly‚ we removed definitions in line 193-194. 5. Line 175. ’As a consequence‚ later breakups were initiated at higher latitudes...’ As a consequence of what? Why should later breakups initiate at higher latitudes? Reply: We replaced “As a consequence” by “In other words” in line 184. 6. Line 246-248. ’These flows were simultaneous with a further auroral activation at 0231 UT near 68.7 MLAT.’ Were the flows observed around 0226 UT by TH4 and TH5 also simultaneous with the further auroral

Science Neutron stars‚ second only to black holes and pints of Guinness as the densest objects in the Universe‚ may have liquid in their cores‚ observations of a dead star shrouded in the debris of a distant supernova suggest. Two separate teams of scientists say that a frictionless state of matter called a superfluid is the only reasonable explanation for temperature changes recently observed in the youngest known neutron star. “This the first direct evidence for superfluidity in neutron stars

The Hubble telescope is a telescope that takes pictures of the universe and has transformed the way scientists look at our universe. The Hubble telescope circles the Earth in 97 minutes at a speed of about 5 miles per second. The telescope has taken hundreds of thousands of fascinating pictures of our universe and all the amazing parts of it. The Hubble telescope was named after Edwin Hubble who had made some of the most important discoveries in astronomy. Hubble travels more then 150 million

Born in 1738‚ Fredrick William Herschel‚ as a young adult‚ he was interested in music and moved to England to excel at the oboe. During his lifetime‚ he composed 26 symphonies as well as several other shorter works. An introduction to astronomy and mathematics by his father turned out to be his new passion. A fascination with telescopes peaked his interest and‚ in 1774‚ he constructed his first large telescope. He would spend multiple hours a day polishing and grinding the mirrors used in the

“What I Learned this Semester about Big History” It is very interesting how you can get a long and sometimes controversial answer to a simple question‚ such as “where does coffee come from?” As we saw in the Bain film and read Big History article‚ one small thing or event is connected to people‚ places‚ and big events on the earth. In the Big History article explains how history is looked at “ from the Big Bang to the modernity.” In modern days we have coffee as part of our morning routine
