NOTHING: The Science of Emptiness
About | Information | History | Online | Facts | Discovery
Why is there something rather than nothing? And what does ‘nothing’ really mean? More than a philosophical musing, understanding nothing may be the key to unlocking deep mysteries of the universe, from dark energy to why particles have mass. Journalist John Hockenberry hosts Nobel laureate Frank Wilczek, esteemed cosmologist John Barrow, and leading physicists Paul Davies and George Ellis as they explore physics, philosophy and the nothing they share.

Nah ahh .

the "host" should give up on his efforts at humour , then again most nerds should.

Our true nature is nothing. We are the eternal void that receives all of life. Google truth contest and read "The Present" to experience your true nature. Once you know your true nature, you will know the truth about life, which is best explained in the 1st 3 pages of the book.

This presenter is funny.

This video had an answer that I've been asking for a long time. Can "real" matter be spontaneously generated from totally empty space? At approximately 54:45 onward Frank Wilczek says that if you take space with everything removed from it (theoretically) it is unstable. Energy is fluctuating from positive to negative and virtual pairs of quark anti-quark pairs are produced. Since there is an attractive force between these particles, when they annihilate there is a net gain in energy. Theoretically that is why the Higgs field is not 0. Sounds to me like the Big Bang is unnecessary, though inflation may have happened locally.

at the end 1:22:50 where John says he worries about the possibility that we won't be able to come up with a spot on T.O.E because there may be other properties of space time that are infinitely weak or almost inconsequential and hard to discover or test is something that I have often thought about myself. It is by no means unreasonable to have this suspicion given that one of the forces that we know governs the universe,gravity, is very weak, and we also have particles that are very inert and hard to detect and also maybe the opposite, particles that may only reveal themselves at extreme conditions, we have no clue about some of the universe's most extreme environments like the center of stars or black holes or for that matter even planets ! it is frustrating also that some of these conditions are (for now) impossible to simulate and study in a lab

There is such thing as nothing, it's in this guys head
-
There is nothing funny about the fact the Prof Wilczek looks like the stereotype of an egghead and the shape of an egg is a good symbol for nothing as well as the cosmic egg.
-
Something exists. Nothing exists. Therefore something is nothing. Language is sure slippery.
-
I realize that presentations like this probably need a mediator but Hockenberry interrupts too often and often at inappropriate times. Great discussion otherwise.
-
57:20 -- As seems to be his job, Hockenberry destroys moments of possibility.
-
Four pseudo smart-asses dancing around the abyss, understanding nothing about nothing. Would have been great to have a decent Zen master challenge their viewpoints.
-
I got absolutely NOTHING from watching this video. Thanks!

Nice Hair Einstein!

We need to come to grips with the fact that everything that we perceive is quite literally inside of our minds. What you experience as reality is nothing more than the sum of everything you perceive through your senses, information which is processed in the brain. Reality could look completely different or it could simply not exist "out there". Solipsism suggests that we can never prove that reality exists independently of ourselves. It is impossible, because the only tools we can use to figure that out are our senses and the brain, things that are made out of the reality we are trying to prove or disprove. It would be like trying to bite your own teeth. When you dream, you do not question the dream, you simply accept that reality and live out the experience. It is only when you wake up that you realize it wasn't "real". But what is real? This moment is inside your head as much as the dream you had last night. That doesn't mean that it is not real. It doesn't mean that it does not matter. It is still a very real experience. Once you come to this conclusion you realize that the nature of reality is purely mental. Not materialistic and mechanical as we previously thought. If you think about it, matter isn't what we think it is. It is not physical. Think about the way physics breaks it down. Eventually you come to the physical world's "building blocks", very small particles that cannot be broken down anymore. Physics even comes to the conclusion that these very small particles are in turn made out of point particles, which are particles that have no spatial extension, they are zero-dimensional, take up zero space. Particles do not simply break down infinitely. There isn't an infinite amount of infinitely small particles. In other words, matter is made out of quite literally nothing. Logically we have to get to this nothingness eventually. Pure nothingness. You can say matter is made out of energy but this energy in turn must come from somewhere else. The Big Bang is no answer as we could ask the same question about it. Where did it come from? People don't even understand what energy really is. When most people think about energy they think about a substance, something tangible like fire. That is not it. Scientifically, energy is described simply as potential. The potential of a given system to do do work. Not a substance. That eliminates energy as an answer for the base of "physical" reality. Because the physical world is ultimately made of nothing, the only logical conclusion is that it is in fact mental, because the only way you and I experience it is mentally, and so do any other conscious beings that may exist.
Ultimately, it is likely that the universe could be just a great thought, as many wise men have said. Following this logic, we can then come to the conclusion that you are the creator as much as the universe is your maker. Maybe the universe simply could not exist without your awareness of it. This also doesn't mean that other people work the same way. Maybe other individuals are simply different points of view. Different perspectives on the world. The universe looking at itself from every possible point of view. Obviously this only leads to more questions, like everything else. Does the world make you, or do you make it? If it makes you what makes it? I believe it is both. The universe depends on you as much as you depend on it. The largest galaxies could not exist without you, and you would not exist without them. You are dependent on the elements created in massive stars, yet to you, these stars would not exist, if you didn't exist. Don't think about this reality as "really out there", remember that we simply cannot prove that the things that we perceive are independent of ourselves. Like I said before, that would be like tyring to bite your own teeth, or touching the fingertip of your finger with that same finger. Makes no sense. Remember that if matter is fundamentally empty, then it cannot be physical. Ultimately everything is one. Clearly this is all hypothetical and unproved by science, but like I said, it simply cannot be proved by science. Never will be. But possible nonetheless. Too baked. -
If you realized that nothing is actually sometihing, then why call it nothing?
-
I'm sorry but that guy's nose boil needs to be lanced before it explodes on the mic.
-
I've seen nothing like this before.
-
The whole reason these guys cannot some to a solution is because their whole model is wrong. There is, was and no such things as the Big Bang. Simple a that.
-
the looks on these guys' faces is quite interesting. It's as if they all know that what they are attempting to do here isn't a thing that's possible. Like they know they can't explain to us what a vacuum is without either taking years to explain it so are using metaphors and analogies which they know are not satisfactory or sufficient. They appear to be quite amused by the entire process.
