Is gravity the force that binds an electron to the nucleus?
Not actually. It is the Coulomb force, also called electrostatic force or Coulomb interaction, attraction or repulsion of particles or objects because of their electric charge. Two variables affect the strength of this attraction: The distance between the char…
Science and the Realm of Physics
What is your first reaction when you hear the word “physics”? Did you imagine working through difficult equations or memorizing formulas that seem to have no real use in life outside the physics classroom? Many people come to the subject of physics with a bit of fe…
How Higgs Boson was discovered ?
Creating even one Higgs boson requires a tremendous amount of energy. The Higgs boson is 125 times heavier than a proton. At a proton accelerator and collider like the LHC, most of the energy in creating a Higgs boson comes from the kinetic energy of the proton…
Types of Supernova
Type IA • Their spectra show very little hydrogen and a lot of carbon • Astronomers believe this type of supernova results from a white dwarf that has collected too much material for its internal pressure to withstand. Once its mass reaches 1.4 times that of o…
The arrow of time
By all accounts, we seem to live in a universe whose arrow of time only goes in one direction – forward. Whether we like it or not, adventurous journeys into ancient history may forever remain a mere figment of human imagination. But what if we had the opportu…
Introduction to Spacial Relativity
Relativity . The word relativity might conjure an image of Einstein, but the idea did not begin with him. People have been exploring relativity for many centuries. Relativity is the study of how different observers measure the same event. Galileo and Newton devel…
How does a photon accelerate to light speed so quickly?
A photon of light does not accelerate to light speed. Rather, a photon is already traveling at light speed c when it is created. It's not like a photon jumps from a speed of zero to light speed instantaneously. Rather, a photon is always traveling at…
Interesting Fact about Pluto
The dwarf planet Pluto is named for the ancient Roman god of the underworld. In Roman mythology, Pluto was the son of Saturn who, with his three brothers, controlled the world: Jupiter controlled the sky, Neptune controlled the sea, and Pluto ruled the underw…
Einstein’s General Relativity Proved
On 29th May in Physics History – In 1919, Newton’s law of universal gravity still dominated scientific discourse, as it provided extremely accurate explanations of physical observations. But Einstein had a major issue with Newton’s theory: It wasn’t consistent…
Population of Stars
• Population I, or metal-rich, stars are young stars with the highest metallicity out of all three populations, and are more commonly found in the spiral arms of the Milky Way galaxy. The Earth’s Sun is an example of a metal-rich star and is considered as an inte…
What was before big bang?
Big bang was the event which created everything we can see, touch, feel etc. Actually that was the starting of everything, and this really meant everything space, time, sound, light, atoms, electrons, etc. Calculated predictions says that, the event of big bang …
Why are the Planets all of the same shape?
Sometimes scientists like to describe Earth as a blue marble because it’s round and has so much water. Earth’s oceans are pretty special—other places in the solar system have no seas, or any trace of liquid water is locked up under miles of ice. But our planet’s ro…
Why Einstein is Overinterpreted?
Einstein is famous for his General Theory of Relativity (GRT), because his gravity is only interpreted as the curvature of space-time. This is much more vivid for us than Newton's gravity with mass attraction proportional to 1/r² and a gravitational co…
Introduction to Black Hole
What is Black Hole? A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predic…
