There is no such thing as absolute zero. The Heisenberg Principal doesn’t allow it. But at about 1.1 trillion degrees, so I’ve heard, quarks unbind. And so you’d have a direct matter-to-energy converter if you could just heat things to that temperature.

"When we experience a radioactive decay, a nuclear fission or fusion reaction, or even — if we make our measurements precisely enough — an energy-liberating chemical reaction, the mass of what we start with (the reactants) is greater than the mass we end up with (the products), rendering the old law of “conservation of mass” invalid."

It even applies to dynamic, non chemical reactions. If you burn a candle some mass is converted to heat. Whereever that heat is absorbed, mass is increased.

Technically correct. Your measuring device would be destroyed..................

Well, my physics dose for the day. Not sure what part I actually understand.

(How the heck did Einstein come up with the “speed-of-light squared” part of the E=Mc2 equation? Haven’t seen anything that explains how/why it takes exactly the speed of light squared to balance the equation and convert mass into energy in understandable terms to the average person.)

“The speed of light is constant, whether you’re moving or not. That blows my mind.”

The speed of light IN A VACUUM is constant, whether you’re moving or not.

It slows down in a medium.

Carbon neutral and far more deadly than CO2.

“Over 90% of the mass of baryonic matter is actually in the form of the relativistic kinetic energy of quarks.”

We have models from which we can make calculations but in truth energy and matter are interchangeable.

We really don’t know either.

It is amazing, isn’t it?

Since nothing can exceed the ‘Speed of Light’, the Speed of Light SQUARED is an impossibly infinite large number. Since mass increases as you approach the Speed of Light, the amount of Energy produced at the SQUARED Speed of Light is unbelievably large.

Converting Mass into Energy is a dangerous undertaking..............

“Converting Mass into Energy is a dangerous undertaking..............”

You do it zillions of times a day.

When you eat, you convert mass into energy.

When you turn on a light you convert mass to energy.

There are still a lot of things we don’t know. Special Relativity was not that tremendous of a discovery, by the way. Einstein just put together the pieces of what others have already discovered, revealing a larger picture. What put Einstein on the map is his theory of General Relativity. The proved the first one was no accident. It started as a simple idea: just apply Special Relativity to gravity. But it opened up a whole new can of worms.

“Since nothing can exceed the ‘Speed of Light’”

The expansion of the universe exceeds the speed of light.

I haven’t researched that area. What others had discovered his postulates regarding inertial frames and the speed of light?

The proof of the Theory of Relativity is that time moves slower when your in-laws are over.

Until Einstein, no one could understand why the speed of light was always the same regardless of the speed of the observer. The concept of space-time had already been around. The speed of light had already been determined. What Einstein did was introduce that space and time are relative to the speed of light. Time could slow down, space could contract, from an observer’s point of reference. Only the speed of light (through a vacuum) was absolute, which made everyone think “Oh yeah. I never thought of that. He’s right, by George”. So Einstein took a mystery and solved it. Put the puzzle pieces together, as it were.

Yet his equation specifies speed of light squared. Why not just speed of light or speed of light cubed? Have yet to hear an explanation in laymen’s terms of the speed of light squared part.

And yes, converting mass to energy is obviously very dangerous as the residents of Hiroshima and Nagasaki found out.
