Why are Black Holes black? We all know: black holes are black. No light escapes a black hole. But, why?  We come across the answer for this while studying gravitational red shift. Gravitational Red Shift Gravitational red shift is similar to the concept of Doppler red shift, but different. Doppler red shift is a change (lowering) in frequency of a wave due to its velocity. But, gravitational red shift is the lowering of frequency of a wave due to gravitational force in the space-time fabric. The derivation that explains this shift happens o be simple, but we shall leave that for now. At the end of the derivation we conclude that the relative frequency change of a wave (due to gravitational force) equals to GM/c 2 R; where G and c are our familiar constants - Newton's 'G' and the light's 'c', and M and R are the mass and radius of the star respectively. The star here could be the star of any phase - a main sequence star, a super giant or even a ...

GRAPHENE Graphene had been a matter of wonder since 2004 and research studies on its applications and potentials been vigorous since. Graphene claimed unbeatable potentials and capacities. But, now, a fellow competent has arose. With Boron much similar to Carbon, the new attention is towards Borophene, which is the two-dimensional monoatomic layer of Boron, just like Graphene for Carbon. So, before exploring Borophene, we shall now see for Graphene and its applications for energy. Overview Graphene is a two- dimensional single atomic layer of Carbon. It is a good conductor of electricity and very strong that it is planned to be used for space elevators. And the strength of Graphene is that, it is the strongest material in the world! The strength results from the power of the carbon-carbon tetravalent bonds. A good semiconductor, Graphene also stands a candidate for superconductors. Graphene for Energy An Eternal Source of Energy from Graphene Under suitab...

SONOLUMINESCENCE Sonoluminescence: the phenomenon of production of light from sound; to be said the simplest. The interesting matter is that, we don’t know how! Science is searching for explanations. Okay, so let’s talk about sonoluminescence. SOME PHILOSOPHY Some hold that everything we discover these days, from the past many centuries, are but re-discoveries only. The knowledge about everything had once been acquired; but it got lost. Personally, Echo Delta as well believes in it. And, all those are not really ‘lost’, but rather is now hidden in scriptures like Mahabharata, Holy Bible, Holy Qur’an, Torah etc. So, why am I talking about this now? Genesis 1.3 of the Old Testament, Holy Bible, goes as follows: ‘Then God commanded, “Let there be light”- and light appeared.’ This command is the first command of God. And, when light was ‘created’, what He saw was water. This might imply sonoluminescence. Yes, I mean it. God produces a sound, that sound creates light: so...

Greetings! We’ll be talking about the most tiny bit of anything, here. Yeah, so what’s everything made up of? Atoms?? And what about atoms? They’re made of protons, neutrons, electrons and aaahh! Now, what about the protons and neutrons? Further they are made up of sub-atomic particles; quarks, in this case. (A/N: following the remarks that this blog’s English is ‘non-decipherable’ by many, Echo Delta shall be trying to dilute it… ‘if not for my reader, then for whom do I write.’) FERMIONS AND BOSONS Basically, what do we have around us? Matter and force. We are materials (~from matter) and so is our Earth. The Earth holds us on it by gravitation. The gravitation here is the force, obviously. Thus everything around can be seen as matter and force. Force is by means of which matters interact. What are the tiniest bits of matter and force? Yes, it’s time for the heroic entry of our protagonists! (^drum-rolls please^) the FERMIONS AND BOSONS!!! Fermions are the particles of matter, and...
