Is it the end of Physics yet?
930067
A few years ago, Stephen Hawkings delivered a public lecture about "the end of physics", and conceded that Godel's theorem suggests that we're not ever going to reach "the ultimate theory of everything".  Here's a link containing his lecture.  In short, Godel's theorem, which orginally concerned logical theory, proves that it's not possible to know for any given number of assumptions accepted to be true, there won't exist statements that cannot be decided as a fact or not based on those assumptions.  Hawkings suggests that no matter what "ultimate theory of everything" we come up for physics, there could always be phenomenon not explanable by it.

The answer is a definite Maybe.\nAs for the space elevator, my understanding is that to complete one, we would need an ultrathin, ultralight, flexible material wit a tensile strength surpassing all we have now. Quantum Physics is THE tool for people who design new materials. Without using quantum physics, it would all be simply trial and error.\nTime travel is a very slippery subject and I can't comment on that. Right now we have no idea how to begin thinking about it.\nMolecular transport, as in beaming stuff the Star Trek way?\nI'd say there's a lot of problems with that, but quantum physics is the very starting point. All that happens to molecules is subject to quantum laws. Therefore I don't know if qf can bring those things abot. However, nothing else can.

When you talk of the possibilities of Matter and Anti-Matter...we already have them.\n\nProblem in lies that if you seperate matter and anti-matter and combine them to forn energy, you have to find a way to contain the energy (there is alot from a small cumbustion)  There is the problem.  So my thoughts are not yet ready for warp technology.

theorically yes.   The problem is discovering and proving the right theory.   It maybe 500 years but we will eventually solve the cold fusion problem.

Since it's a theory as of now, there's no way to prove whether it exists or not.  My opinion - I think there may be things underway that are leading to it sometime in the future.  With the way things are in the world today, it will take something very extraordinary to bring it about.

The latest developments are very technical and hard to translate into non-mathmatical terms that lend themselves to this format.  Check the physics journals for the latest (see the link below).\n\nIn general lay terms, some of these developments include time evolution, D-branes, a variety of developments on tachyons, guage fixing, and time lumps.

My turn. In about 200 years, when we are all dead and the Yahoo! gods have ceased to exist, another scientific discovery will be made that will render all previous knowledge useless. \nThis discovery will come at a time when Six Flags has closed it's last roller coaster in Greenlands' "Damn it's Cold" park and 6000 people, who can no longer e-commute to work, have to actually turn off their computers and go OUTSIDE into the sunlight. The experience will spark Wide Spread Panic and Dancing in the Streets. \nWho cares? WE WILL BE LONG GONE!!!!

All it means is that we don't know everything. We've learned quite a bit in the short time since we developed written language and the scientific method, and the rate of learning is accelerating. We'll learn more in the next 10 years than we've learned in the last 100. We'll probably understand the nature of dark matter in the next 10-20 years, and I would bet long odds that it won't require any supernatural explanation.

Not much;  quantum mechanics is pretty much taken for granted (by physicists, NOT philosophers!) as the framework of almost all of modern physics (but gravity's another story...).  In that sense almost all physics research these days is "quantum" physics.  However, there is still some interesting work being done with phenomena that are distinctly quantum mechanical, such as Bose-Einstein condensation, quantum entanglement, and the like.\n\nI'd just like to point out that in the past 100 years since quantum mechanics was "born", no experiment has been performed whose results are not consistent with quantum mechanics.

Yes, physics is interesting and it is the study of how nature works. Keep trying and thinking about things. Develop your logic and things will be easier to understand.

I think that is a lot of hooey. nothing is going to replace science.

No, but some physicists think they have.  String theory is the most popular unifying theory, but it makes no testable predictions, meaning that its really more philosophy than hard science.  There are other theories out there too.  For example , Heim Theory involves extra dimensions in which the speed of light is different in order to unify the four fources (electromagnetic, strong, weak, gravity).

well, spacetime does not seem to end, and nothing is "holding up" spacetime.\n\nthe universe is not infinite. the universe is finite yet has no edge and no center. it may be something like the two dimensional surface of a sphere. nothing inside or outside the sphere exists for the two dimensional surface.\n\nalso, i have something for you to think about. the radius of observable universe is about 46 billion lightyears, yet the universe is 13.7 billion years old.

It hasn't been done yet (we just don't have the technology to do it) but it is not against the laws of physics in anyway so it'll happen at some point in time.

No. Actually, the string theory is dominating physics. The string theory tries to combine the Theory of relativity and the quantum mechanics, forming the so-called " theory of everything". This theory should combine all the four elementary and fundamental  forces - Gravity, Weak Nucleur Force, Strong Nucleur Force, and the electromagnetic force. The String theory is still in progress. If you want to know more about this from me, e-mail me at supratim1_dey@yahoo.co.in.\nI am actually a theoretical scientist researching on the string theory. You have a very nice question. I will recomend you two books of Stephen Hawking - 1- Brief History of Time and 2 - Black Holes and Baby Universes.

Wow.  You're asking if the cosmos is producing reality.... Hmm... \n\nThere are two theories that are generally accepted as the most plausible; General Relativity, and Quantum Mechanics.  General Relativity deals with things on a large scale, like the movement of planets, asteroids, people, etc.  Quantum Mechanics deals with the actions of things on a much, much smaller scale, the building blocks of matter, particles much smaller than the particles that make up protons and neutrons.  The problem is rectifying these theories, because at the moment, they don't agree with each other, but they're the best we have.  A new emerging theory is String Theory, which blends them together reasonably well.  If you want to learn about them, a simple Google search will tell you all you need to know.

pondering physics?  you are gone.
