Centaurus A or NGC 5128 is a prominent galaxy in the constellation of Centaurus. It was discovered in 1826 by Scottish astronomer James Dunlop from his home in Parramatta‚ in New South Wales‚ Australia. It is one of the closest radio galaxies to Earth‚ which means that its galactic nucleus has been extensively studied by professional astronomers. This particular galaxy is also the fifth brightest in the sky. The galaxy contains a supermassive black hole with a mass that is equivalent to 55 million

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

Theoretical Physicist Adam Brown writes about the possibility‚ or as it turns out‚ the impossibility to mine energy from black holes. It is common knowledge that the Earth’s resources are being burned through at an alarming rate. This issue has lead to many people seeking other sources of energy. However‚ the article poses the question‚ what happens after humanity find the new form of energy and exhaust that? Some propose should the descendants of the human race seek help from the stars. Ironically

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

physics honors Acceleration due to gravity by picket fence method Varun Kumar Pd 7 Saumya Kapoor & Tonia Li 9/26/2014 INTRODUCTION Acceleration is the increase or decrease in velocity. It can also be described as the rate of change in velocity. Acceleration is represented by the formula: . In this experiment we look at a specific type of acceleration‚ Free-Fall. Any object that is being acted upon only by the force of gravity is said to be in a state of free fall. There are two important

The difference between speed and velocity is that Velocity also includes a direction the acceleration of gravity on earth is approximately 10m/s2 if you drops rock from a tall building‚ about how fast will it be falling after 3 seconds? 30m/s Momentum is defined as Mass time’s velocity suppose you live on the moon. Which of the following would be true? Your weight would be less than your weight on Earth‚ but your mass would be the same as it is on Earth. In which of the following

TOPIC 1: WE LEARN THROUGH DIRECT EXPERIENCE; TO ACCEPT A THEORY WITHOUT EXPERIENCING IT IS TO LEARN NOTHING AT ALL. Learning is a process including both practical experience and theoretical knowledge. We couldn’t say that accepting a theory without experiencing it brings us nothing at all; however‚ we can have a deeper understanding of information if we encounter them in our real lives. And I believe that pragmatic experience is the fastest and easiest way to learn things. Infants are born knowing

ANALYSIS There are lots of topics to be discussed in Physics. There are always new discoveries all the time. The world‚ and everything in it‚ moves. Even seemingly stationary things‚ such as a roadway‚ move with Earth’s rotation‚ Earth’s orbit around the Sun‚ the Sun’s orbit around the center of the Milky Way galaxy‚ and that galaxy’s migration relative to other galaxies. Dynamics is the study of the relationships between motion and forces. One of its branches is Kinematics‚ which is the lesson for

Black holes are some of the most fascinating and mysterious parts of space. It has so much gravitational pull that nothing can escape from it‚ even light if it gets close enough. Albert Einstein predicted black holes back in 1916. The term “black hole” was made up in 1967 by an American astronomer John Wheeler. The first black hole was discovered in 1971 by rockets that were carrying Geiger counters that came across eight new x-ray sources. Scientists that detected radio signals coming from it found
