The first process the solar nebula underwent involved its collapses. As it shrank or collapsed, the temperature of the solar nebula rose and its gas particles increased in speed. The Sun forms in the center of the cloud, where the temperature and particle density is at its highest.…

In 1974, Hawking's research turned him into a celebrity within the scientific world when he showed that black holes aren't the information vacuums that scientists had thought they were. In simple terms, Hawking demonstrated that matter, in the form of radiation Some of the awards Hawking has received for his work include the 1979 Albert Einstein Medal, the Order of the British…
“A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—including particles and electromagnetic radiation such as light—can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.” (Source 1)…
A nebula, an immense cloud of hydrogen gas and dust, condenses into smaller regions of matter. On occasion, one of these regions collapses under the force of its own gravitational attraction, often triggered by an outside force, like a nearby supernova-an explosion of a star. After the collapse of a cloud, atoms begin gravitating together to form a condensed center. The condensed center is a protostar. As gravity pulls in more gas and dust, pressure builds, causing the protostar core to heat up. Clouds and matter begin to rotate around the protostar and flatten due to their rotation. They surround the protostar like a rotating disk. The protostar continues to grow and its core continues to heat. When the core is hot enough, nuclear fusion begins. The start of nuclear fusion is technically the beginning of a star's life. Eventually, when the nuclear energy runs out, the star dies. Depending on the size and mass of the star, it can go through many stages and die in different ways-one of those ways being a supernova.…
The energy that comes from nuclear fusion hinders the star from continuing to fail. When the star reaches this union, at the moment that the nuclear fusion comes to light what was gas is now a star. In this situation, the Sun is the after math. In the existence of the Sun it is where we are in the here and now. Through nuclear fusion the Sun keeps on burning. Tens of thousands of years the nuclear acknowledgment will produce high- energy electromagnetic waves and they move out into space. They make contact with the surface and when moved into space by lower energy visible, infrared light, and ultraviolet light, (Villanueva, 2010). This is what exactly what defines lightens our planet today. Later when the hydrogen gets absorbed into helium, there is no more energy which will empower it to push out and block the Sun from being diminish. In the end the Sun would…
Every star has a life cycle just like a human or a frog except stars do it on a much larger scale. Stars start life as a massive cloud of matter and then get pulled together to create a star. But stars do not last forever most stars last for millions of years but they still end. When a stars life ends it may explode or implode to create a black hole.…
When we look into outer-space today we see billions upon billions of stars the cover the “universe”, but what may have crossed your mind is how did they get there? Well before, these stars were there it was said that the universe was a very hot, small, and dense with no stars, atoms, forms “singularity”. The way that the universe became what we see today is what scientist calls “The Big Bang Theory” not to get confused with the show. Scientist base the Big Bang theory on many different factors/observations. The most important is the “redshift” of very far away galaxies. Redshift is the doppler reaction that occurs in light. When an object moves away from earth, it looks reddish because the movement stretches the wavelength. The reddish color occurs because; red is the lowest wavelength on the visible. The more redshift there is, the faster the object is moving away. By measuring the redshift, scientists proved that the universe is expanding and can even work out how fast the object is moving. Basically, what happened is that “space” became expanding very quickly about fourteen billion years ago, and which resulted in the formation of atoms, which eventually led to the creation of stars and galaxies. Space as we know it was created, and is still expanding at a very rapid rate while becoming much cooler.…
Because of some perturbation, conceivably from a proximate supernova, under its own gravity force, this cloud of gas and dust began to condense, or shrink together. At first, the condensation was slow, but the speed started to increase as more material was being pulled towards the middle of the nebula. Eventually, this made gravity get stronger, making the process of condensation faster (Msnucleus…
In a dark room lies a dimly lit light, as bright as a Minecraft furnace during a pit black night, considering your Gammas turned down. The ball of light, as if pulled by a gravitational force, flies towards what seems like a black hole.…

14. “galaxies swallowed by galaxies, whole solar systems collapsing, all of it acted out in silence.”- Nick Flynn Cartoon Physics, Part 1…
Talking about the universe is always a mysterious subject for us. There are lots of theories about the universe by different scientist. Nobody actually knows the reality. Like the universe the topic,” Black Hole”, is also mysterious. We know what black hole is but we are not able to give the detail information about it. As everybody says that,” black hole is a region in space that has an indefinite density and the gravitational force that does not let anything escape from its influence that includes light too”. There is kind of debate among the scientist about considering sun as black hole. Many believe that the mass of the black hole is 10 times more than that of the sun, so we cannot consider sun to be the black hole. There is question in everybody mind what is black hole? , how it is originated? , what black hole able to do?…
The universe is laden with mystery and wonder; there is no shortage of questions to be asked about the nature of the cosmos. The questions that civilization asks about the universe reflect societies values, such as asking the question of how the universe will ultimately die. The answer to this question begins with one of the fundamental forces of the universe, gravity. If a football is thrown gravity acts on the ball as soon as it leaves the hand of the quarterback, the football starts losing speed and reaches its peak height after returning back to earth because the force at which the ball was thrown was not enough to break through earths gravitational pull. This idea was also applied to the expansion of our universe. During inflation (expansion…
