I read one science fiction story where the bad guy gets thrown into a black hole and he screams in fact he screams forever.

I'm dr Michio Kaku professor of theoretical physics and best selling author of the God equation and I'm here today to answer your questions on twitter.

This is physics support cal is not a cow ask y'all, why do atoms want to bond so much?

You aren't missing anything Adams want to bond together.

Universes based on atoms which like to bond with each other, the electron vibrates back and forth binding them together.

That's why we have you you are a consequence of the fact that electrons are shared between different atoms.

Debra morrow Zach asked the question, What's your favorite law of physics?

Well my favorite law of physics is the equivalence of matter and energy.

It's why the stars twinkle, it's what lights up the universe.

We like to think that matter and energy are totally different things.

However if that rock is uranium and that energy is the fireball of the nuclear bomb, you realize that matter and energy or two sides of the same coin.

Matter energy is one unit and they can flip into each other under certain circumstances like in the heart of a star Sean Harris at info sec Hotspot asked, does anyone know of people like Michiko Kakutani that can explain string theory like he does for people like me and I'm not a genius.

Well I am Mikio Kaku and I'd be glad to answer that question.

First of all, most textbooks say that an electron is a dot, particles that we see in our atom smashers are dots.

But if I had a super microscope, I can see that that dot is actually a rubber band.

From a distance, this rubber band looks like a dot close up.

Now this rubber band can vibrate in many different modes.

So for example, this might be an electron, but if you total it in a different way, it becomes a quirk.

And if you toilet this way you have to give it a different name.

We call it a neutrino Now, how many ways can one string vibrate?

An infinite number of vibrations on the same string.

And so we think that all the subatomic particles of the universe, the corks, the neutrinos, the mesons, the protons and neutrons.

There's a galaxy of these particles, there's nothing but musical notes on a tiny rubber band.

A rubber band so small that it looks like a dot.

So what is physics that we have to struggle with In high school physics is the harmonies.

Physics tells us how these vibrations move with its chemistry.

Chemistry is when these strings bump into each other and form molecules Alex add cure asks kong asked what is a quirk?

What is OMG Yeah it's a oh my God, we think that inside the proton there are three quirks, subatomic particles that make up the protons and neutrons which in turn make up our universe.

Here's a question from Rick at Sojourner 99.

We live in four dimensions but can see three, how many dimensions are there?

Einstein says we live in a four dimensional world.

We can go forward, backward, left, right up down and the fourth dimension is time.

But now we're beyond Einstein And we have to go beyond four dimensions to perhaps let's say 10-11 dimensions.

We think they have curled up there so small that you cannot enter them.

Perhaps a parallel universe hovering right above your universe in another dimension, that we cannot see your touch.

But perhaps there's a gateway connecting them.

That gateway is the wormhole, it was Einstein himself in 1935 who introduced the concept of a wormhole, a gateway between higher dimensional universes.

Well the next question comes from J mo Zach who asked the quantum universe?

Was Einstein wrong about his theory of relativity.

There's a famous quote where Einstein said the more successful the quantum theory gets the sillier it looks, he thought that atomic physics that is quantum mechanics was incomplete when the Nobel prize was given to people like Heisenberg, he said yes, give them the Nobel prize, they're onto something.

And so Weinstein had reservations about the quantum theory as the final theory.

He thought there had to be a higher theory, a theory even beyond the quantum theory.

Obi would shana lang asked what is the God equation?

Well, Einstein spent the last 30 years of his life Chasing after the God equation.

An equation perhaps no more than 1" long.

That would allow us to quote read the mind of God, a theory that would unite the two branches of physics.

On one hand we have the theory of the big general relativity, black holes, big bangs and the theory of the small quantum theory.

How can you unite these two into one theory at the present time.

They're based on different mathematics, different principles, different concepts.

And yet we believe in our heart of Hearts.

There has to be a master theory out there.

The Holy grail of physics and that we think is the God equation.

The leading and only candidate for that is string theory.

And by the way, if you ever find the God equation, Tell me first, we'll split the Nobel prize money together, you and me, here's a question from Princeton University Press and that is who is your favorite physicists?

46.2% said that Einstein was their favorite physicist.

53.8% thought that Richard Feynman was their favorite physicist.

He asked the question for the ages if an apple falls, does the moon also fall?

And he realized that he didn't have the mathematics to calculate a falling moon.

He invented his own mathematics called calculus and the theory was one of the greatest theories of all time.

Newton's law of gravity and so during the black plague of 16 66 one of the greatest minds in history went from superstition and thrust us into the age of mechanics.

The Industrial revolution, he changed world history, You can't beat that.

Einstein is way up there, so is Richard Feinman, but Isaac Newton tops them all.

The next question comes from Hassan baba ji who asked can light bend around corners if yes or no, give one reason, yes.

In fact, that's why we have glass inside your glasses.

When light goes into glass, it slows down slightly because it slows down, it deviates from a straight line and that's why we have your glasses telescopes microscopes because glass bends light also gravity can bend light as Einstein showed us.

And we can actually see the bending of light as it goes around a galaxy.

Then the next question is can you bend light completely around an object?

It's well within the laws of physics that if you could govern the atomic structure of glass then light would bend in a way such that it would completely go around an object.

So anything inside that object becomes invisible.
