What is the answer to life, the universe, and everything?

Question

If you know the answer, then say it and the question too, if you know it.

Answer 1

Answer 2

Can there really be a unified theory of everything? Or are we just chasing a mirage? There seem to be three possibilities:

• There really is a complete unified theory, which we will someday discover if we are smart enough.

• There is no ultimate theory of the universe, just an infinite sequence of theories that describe the universe more and more accurately.

• There is no theory of the universe. Events cannot be predicted beyond a certain extent but occur in a random and arbitrary manner.

Some would argue for the third possibility on the grounds that if there were complete set of laws, that would infringe on God’s freedom to change His mind and to intervene in the world. It’s a bit like the old paradox: Can God make a stone so heavy that He can’t lift it? But the idea that God might want to change His example of the fallacy, pointed out by St. Augustine, of imagining God as a being existing in time. Time is a property only of the universe that God created. Presumably, He knew what He intended when He set it up. With the advent of quantum mechanics, we have come to realize that events cannot be predicted with complete accuracy but that there is always a degree of uncertainty. If one liked, one could ascribe this randomness to the intervention of God. But it would be a very strange kind of intervention. There is no evidence that it is directed toward any purpose. Indeed, if it were, it wouldn’t be random. In modern times, we have effectively removed the third possibility by redefining the goal of science. Our aim is to formulate a set of laws that will enable us to predict events up to the limit set by the uncertainty principle.
The second possibility, that there is an infinite sequence of more and more refined theories, is in agreement with all our experience so far. On many occasions, we have increased the sensitivity of our measurements or made a new class of observations only to discover new phenomena that were not predicted by the existing theory. To account for these, we have had to develop a more advanced theory. It would therefore not be very surprising if we find that our present grand unified theories break down when we test them on bigger and more powerful particle accelerators. Indeed, if we didn’t expect them to break down, there wouldn’t be much point in spending all that money on building more powerful machines.
However, it seems that gravity may provide a limit to this sequence of “boxes within boxes.” If one had a particle with an energy above what is called the Planck energy, 1019 GeV, its mass would be so concentrated that it would cut itself off from the rest of the universe and form a little black hole. Thus, it does seem that the sequence of more and more refined theories should have some limit as we go to higher and higher energies. There should be some ultimate theory of the universe. Of course, the Planck energy is a very long way from the energies of around a GeV, which are the most that we can produce in the laboratory at the present time. To bridge that gap would require a particle accelerator that was bigger than the solar system. Such an accelerator would be unlikely to be funded in the present economic climate.
However, the very early stages of the universe are an arena where such energies must have occurred. I think that there is a good chance that the study of the early universe and the requirements of mathematical consistency will lead us to a complete unified theory by the end of the century—always presuming we don’t blow ourselves up first. What would it mean if we actually did discover the ultimate theory of the universe? It would bring to an end a long and glorious chapter in the history of our struggle to understand the universe. But it would also revolutionize the ordinary person’s understanding of the laws that govern the universe. In Newton’s time it was possible for an educated person to have a grasp of the whole of human knowledge, at least in outline. But ever since then, the pace of development of science has made this impossible. Theories were always being changed to account for new observations. They were never properly digested or simplified so that ordinary people could understand them. You had to be a specialist, and even then you could only hope to have a proper grasp of a small proportional of the scientific theories.

Answer 3

The answer to life is free will, do what u want. The answer to the universe is probably the fact that just explore it and the answer to everything is just do what makes u happy to certain extent.

Answer 4

The answer is to ask as many questions as you can and try to get as many answers as possible. It is evident that we as humans are very stupid and in actual fact kow very little. But I do know some things as a knight of the old code. Firsly the answer is chivalry - being as honest and honorable as possible. Secondly the answer is bravery - by enduring life through courage i believe we get rewarded later on. Thirdly the answer is spirituality - look at the american indians , they were happy and they were a fantastically spiritual people.

Answer 5

Since you are here to ask the question, the answer to your life is in you. Again, the answer to the universe lies in you and your perception of it. The question is, "what is everything", the answer is in you. What is everything to you?

Answer 6

Christopher Walken. He is the answer to life, the universe, and everything else.

Although some people might argue and say that it is Chuck Norris.

But no, it is Christopher Walken.

Answer 7

a big cigar while soaking in the hot tub with a glass of what ever you like to drink that is the answer to everything

Answer 8

There isn't one, it's the search that keeps the whole in action and action, that is what we crave even more than the many answers we encounter on the way.

Answer 9

No, I don't know, but why not read the books which Stephen Hawking once produced, as one starting-point.

Answer 10

Do they exist? Yes.
Do we understand a bit about them? Yes.
Do we understand them fully? No.
Does it matter? No.
