E = mc^2 Explained by Michio Kaku

E = mc^2 Explained by Michio Kaku

Welcome to an enlightening journey through the cosmos with none other than Dr. Michio Kaku, a renowned theoretical physicist and futurist. In this video, he takes on the task of explaining one of the most groundbreaking equations in the world of physics - E=mc^2.

Dr. Kaku, born on January 24, 1947, has dedicated his life to the field of theoretical physics. He is one of the co-founders of string field theory and has made significant contributions to our understanding of the universe. His ability to communicate complex scientific ideas to the general public has made him a popular figure in the world of science communication.

In this video, Dr. Kaku turns his attention to Einstein’s mass-energy equivalence principle, encapsulated in the equation E=mc^2. This equation, though simple in appearance, carries a profound implication - mass and energy are two sides of the same coin. They are interchangeable.

Dr. Kaku starts by breaking down each component of the equation. ‘E’ stands for energy, ‘m’ for mass, and ‘c’ is the speed of light in a vacuum, which is a constant. The equation tells us that the energy (E) of an object is equal to its mass (m) times the square of the speed of light (c^2). This means that even a small amount of mass can be converted into a large amount of energy, and vice versa.

He then delves into the practical implications and applications of this equation. It plays a pivotal role in nuclear fusion and fission processes, which are responsible for generating vast amounts of energy in stars and nuclear power plants. The equation also underpins our understanding of how matter behaves at a fundamental level.

Dr. Kaku further explores how this principle could be harnessed for future technologies. For instance, if we could find a way to convert mass into energy efficiently, it could potentially open up new possibilities for space travel.

This video is not just for physics enthusiasts but for anyone curious about the universe we live in. So join Dr. Kaku on this journey through space and time as he unravels the mysteries behind E=mc^2.

I'm not fat, I'm just moving fast

[alejandropflucker]

MR. KAKU HAVE THE GREATER EASY WAY TO EXPLAIN THINGS, SPECIALLY THE COMPLEX CONCEPTS OF IS TO BE A VERY VERY GOOD TEACHER....

[leszekterczynski]

I wanted to lose a few pounds, but from today I stop running and jogging😉

[jezdrawz]

The thing about this that a lot of people misunderstand is that the "mass" that the energy has a relationship with is not just the "mass" that is "matter" but rather relates closer to "inertial mass" which we all know that "inertia" is the ability of an object to "resist" the change of its state of motion. This literally proves the fact that it is near impossible for an object with mass to reach the speed of light or faster than the speed of light.

[reynaldoalcala]

science is sweet when the teacher knows what he is talking❤😂

[olamilekansaheed]

The faster you go, the heavier and lighter you get.
The heavier you get in the direction of travel, and the lighter you get in the upward and downward direction.
This explains why a moving vehicle can flip over several times when the wheels bumped into an obstacle at high speed.
Also explains why you can jump higher when running

[johnwaters]

So, mass = E / C-squared
look at it in this context
for a constant E, the faster...mass smaller
what am I doing wrong?

[LeReal]

This other time Enistine said " the faster you move the slower time ticks."😂

[RiverwestRadioWXRW-FM]

So how much does a jet increase in weight as it reaches to speed? Is it noticeable?

[tasmanpr]

How much does sun light should weight given the speed? It has no mass? But then its energy should be 0. Enlight me pls

[noor.mohmand]

But when you drive your ar the faster you travel the lighter it becomes. Any thoughts on tis doctor Michio?

[mohammadzahidurrahman]

The interpretation of e equals mc squered that I knew is when mass moves at the speed of light then mass becomes energy.

[Trisontraileryt]

But how do you explain m=2KE/vsquared?

[waynelast]

As you put energy into an object to make it go faster, it gains inertial mass, which is just equivalent to saying additional input of energy can only make it go a little faster, until you finally reach a point where the fastest it can move is the speed of light.

[kawi]

How do you measure weight that is moving through air or space? How can they tell it’s heavier?

[syedquadri]

The faster you move the heavier you get - 'Thats what she said' 😂

[KhunRay-yk]

Thank you that valdates the fact that a mass can never reach the speed of light.

[markreed]

Every time I get the urge to exercise and move, I lay down and wait for it to pass, and that’s how I lost weight.

[Boca-do-rio]

So when galaxies move faster and faster away from us, means that? But when then its mass gets bigger, also its gravity should, right? So what happens when these uge masses are going 9/10th of the speed of light?

[adventureswithpasa]

what how m and c become proportional to each other?
