Why Does E=mc^2?

On the one offer, we have substance with mass: from galaxies, stars and planets all the way down to molecules, atoms and essential particles themselves. As tiny as they strength be, every single constituent of what we know as substance has the basic property of mass, which means that even if you take all of its motion absent, even if you slow it down so that it’s totally at rest, it motionless has an power on every other object in the Universe. Specifically, each person mass exerts a gravitational pull on all else in the Universe, no matter how far absent that object is. It tries to attract all else to it, it experiences an attraction to all else, and also, it has a specific quantity of energy inherent to its very existence It’s forever shining, forever ablaze with light and power. In the ubiquity of solar output, Earth swims in an endless tide of particle. Every time half of the Earth faces the Sun, we knowledge the brightness of day, the Sun’s energy and light driving weather, biology and extra. This latest video from the NASA Solar Dynamics Observatory (SDO) is the majority detailed of our Sun yet, and it’s totally mesmerizing.

The SDO was launched in 2010 to check the Sun 24/7 and to better understand how it affects our Earth. To highlight the dissimilar temperatures of solar materials, SDO capture footage of the sun in 10 diverse wavelengths. And all these wavelengths have now been compile into one video.
The 30-minute film even features a particular soundtrack from German composer Lars Leonhard, this footage is offering a real fresh perspective on our own relationship with the impressive forces of the universe. So sit back and enjoy this gripping and most full of the giant ball of energy at the middle of our solar system.
We usually think of energy, at least in physics, as the aptitude to accomplish some task: what we call the aptitude to do work. What can you accomplish if you’re now sitting there, boring, at rest, like massive particles do? And what’s the energy link between massive and massless particles?
The key is to imagine captivating a particle of antimatter and a particle of substance (like an electron and a positron), colliding them jointly, and getting massless particle (like two photons) out. But why are the energies of the two photons equivalent to the mass of the electron (and positron) times the pace of light squared? Why isn’t there one more factor in there; why does the equation have to be exactly equal to E = mc^2?
Interestingly enough, if the particular theory of relativity is true, the equation have to be E = mc^2 exactly, with no departures allowed. Let’s talk about why this is. To start, I want you to imagine you have a box in space, that’s completely stationary, with two mirrors on either side, and a single photon traveling towards one mirror inside.
