How all particles and fundamental forces except gravity interact

Image
 The Standard Model is a physics theory that explains how all particles and fundamental forces except gravity interact. In the 1970s, scientists realized that the accepted theories of the time predicted that elementary particles could not have mass. Except that they knew that wasn’t true; experimeThe sun helped prove Einstein right...nts had already shown that these particles did have mass. Something was missing. Three physicists (Robert Brout, François Englert, and Peter Higgs) developed a mechanism that explained this apparent conflict. This mechanism was later an essential ingredient of what is now the Standard Model of particle physics. They proposed that the Standard Model was missing a field that would interact with elementary particles and that the interaction gives these particles mass. Weinberg, Salam, and Glashow later constructed a complete theory explaining the known interactions of particles, along with their masses. This theory contained an essential ingredient – the...

Let's get to know ELLIPTICAL GALAXIES

Image
  An elliptical galaxy, full of dark lanes of gas, likely formed in the merger of two other galaxies. Elliptical galaxies host less (or no) star birth than spiral galaxies like the Milky Way. (Image credit: NASA, ESA and The Hubble Heritage Team (STScI/AURA)) WHAT ARE ELLIPTICAL GALAXIES?  Elliptical galaxies are the most abundant type of galaxies found in the universe but because of their age and dim qualities, they're frequently outshone by younger, brighter collections of stars. Elliptical galaxies lack the swirling arms of their more well-known siblings, spiral galaxies. Instead, they bear the rounded shape of an ellipse, a stretched-out circle. One of the most famous elliptical galaxies is Cygnus A, which is located roughly 600 million light-years from Earth and is an extremely bright radio source. Cygnus A is not only well-known to astronomers, but has a place in science fiction; it was featured in the 1985 novel "Contact," a Carl Sagan story that later inspired a H...

💥The Sun Helped Prove Einstein Right for his General Relativity theory.

As any good scientist knows, an unproven theory isn’t science, it’s philosophy. Einstein needed his equations to make accurate predictions about the behavior of objects in space.  One of his conjectures held that light traveling near a large gravitational field should curve. To test it, Einstein needed the help of a solar eclipse, which would facilitate the view of starlight passing through the sun’s gravitational field. On May 29, 1919, in a test conceived by astronomer Sir Frank Watson Dyson, and with the help of Sir Arthur Eddington, astronomers were able to take pictures to compare with their "true" location and measure the bend of light of 1.75 arcseconds—the very number Einstein’s theories predicated. “LIGHTS ALL ASKEW IN THE HEAVENS” read the November New York Times headline. From that moment on, Einstein was a superstar. @SciSujan
