When it comes to understanding the relationship between an active galaxy and a black hole, it is one of cause and effect. There is a negative feedback between the black hole and the surrounding galaxy as when the galaxy grows too fast, the black hole produces out-flows that halt any further growth. […]
Accreting black holes at the center of a galaxy are slightly more massive. Gas is funneled toward the innermost edge of the accretion disk. The gas is hot, ionized, plasma and is likely to turn into a tangled internal magnetic field. […]
The Heisenberg uncertainty principle states that energy and time experience a similar relationship. It assumes significance while calculating a particle’s lifetime. […]
Einstein’s equation, E = mc2 can only be used for particles that are not in motion and have a mass. In order for it to work in the case of all the particles, it needs to account for the momentum as well. […]
Were the dinosaurs warm-blooded like birds or cold-blooded like reptiles? Unfortunately, the answer isn’t simple. Each possibility has its merits. Some species may have run warm, while others ran cold. […]
The formation of planets is different from that of stars, although they are formed using material left over after the birth of a star. Starting out the size of a pebble, they grow after millions of years to the size of a planet. […]
It is widely believed that planets with similar mass and size such as Venus and Earth did have similar atmospheres at one point. However, Venus suffered tremendously from the greenhouse effect which rendered its atmosphere inhospitable. […]
The equilibrium temperature formula helps in calculating the temperature of a planet that has reached the radiative equilibrium. It is a state where it doesn’t get too hot or too cold. The formula works in case of Jupiter but not in the case of Venus and Mercury owing to their atmospheric difference. […]
The skeletal muscles allow us maintain our normal posture. Still, studies show that nearly 80% of people experience back pain during their lifetime. […]
Our spine is composed of stacked vertebrae and intervertebral discs between some of them. Even though it is stable in its structure, the spinal column can develop disorders. […]
