can physics explain life?

Kind of.  Biology and chemistry are both based on physics, and since these are used to explain life, physics can explain life in a way.  Of course, nobody really understands what life is, how it evolved, or really any of the fundamental questions about life.\nOn a side note, there is an interesting theory that uses quantum mechanics to explain consciousness, but unfortunately I don't have a source for that.

this is a difficult one. theres the initial 'soup' of early compounds that spawned life, theres the meteorite theory of cells from other planets gettin a start here, and theres a possible link between both. this may be that chemicals from the many rocks from outer space, the heat of the planet then, and the interaction of all the early substances may have harboured a good environment for a cell 2 form, with a membrane, enclosing some of these compounds within it.

it's simply life. Every thing around us every thing we do any thing that hapens and it's cause and how did it happen. the objects around you how are they made what are they what could it do. the way of life...it's the answer of every thing around us....if u need the answer of any thing u have to use science...simply science is every thing and cause

Maybe. It seems that in a universe filled with billions of galaxies, each with billions of stars, each with a potential to have a planet with life around it, that at least a few other planets would have to have life. It is not reasonable to suppose this is the only one where this ever happened. \n\nHowever, you asked about "creatures like humans". This is possible, but no where near as likely as there simply being "life" on other planets. The forces of natural selection ("evolution") can develop life in a myriad of possible shapes, and there is no guarantee that human-like lifeforms will evolve anywhere else. By some points of view, it is virtually impossible since a great many events happened over billions of years that resulted in us looking like we do. There might be life out there, and even intelligent life, but it is probably very different from us. \n\nHowever, another way to look at it finds the possibility that there is life like humans out there. Think about this: how many ways are there to get around: swimming, crawling, brachiating (swinging from trees), flying, walking. Maybe there are a few more that we don't see on Earth. Legs are one of the best ways of getting around, so it seems likely that, if there are many different worlds with life, a large proportion of those worlds have creatures with legs. This same logic applies to arms and hands--how many effective ways are there for manipulation of objects? Tentacles, cilia-like graspers, lobster claws, hands, and probably more. Still, something like hands at the end of flexible or jointed extensions like arms is a very good means of allowing a creature to grab things and shape them, so it seems likely that something hand-like will also appear. And then there are the obvious advantages of having the head on top of the body, for standing upright, for having two eyes set horizontally, etc... \n\nWhat I am getting at here is that there might be a million million ways that lifeforms can be shaped, but perhaps there are only a limited number of forms capable of inventing and building cities or ships or plows etc... Since the ability to create these things have such obvious advantages, life might often be "channeled" by the force of natural selection into the forms that allow technology, and therefore a human-like form might be seen more than just here on Earth.

Look around yourselves almost everything around you has some physics.The computer you use ,the vehicle you drive ,houses we live in ,various appliances we use everything has some physics involved.We are in effect trying to study the very nature of things there physical properties .

Let's get semantical on you.\n\nWhat is biology?... the study of life, right?\n\nWhat is life? Or maybe better way of phrasing that question is: What is alive?\n\nAnything that meets all the following criteria:\n\nAble to obtain and use energy. \nAble to reproduce.\nAble to respond and adapt to their environment. \n\nSo when we study biology we study things that can do these different things and, more specifically, we study how living things do these different things. Basically, we're trying to understand how living things live.\n\nNow, back to you question concerning chemistry...\n\nHow do you suppose living things are able to do all the things on the list above? You guessed it: CHEMISTRY.\n\nAll the processes above are carried out by chemical reactions that take place between different molecules. Most of these reactions include tiny sub-microscopic machines called proteins. All these proteins are doing is carrying out very specific chemical reactions.\n\nSo when you boil it all down, biology is nothing more than the study of chemical processes that take place in living systems. In fact, it's these chemical processes that allow for life to begin with.

An interesting question.  \n\n#1 would seem at first glance to be automatically false, as everyone will agree that there is evidence that there was a time when the things we see today in nature, did not exist.  But to get a little deeper, what if these things are the natural products of natural laws that have always existed?  E.g. what if our universe is just one of an endless series of universes that appear, unfold under natural laws that have been in existence for eternity, and then disappear, only to get reborn again as a new universe?\n\n#2 is the *goal* of a scientific explanation.  I.e. to see how much we can explain by the discovery of natural laws.  Science has no way of knowing if such an explanation will always be possible, but it has to try.  And so far we have done remarkably well ... almost everything we see in nature can be explained in terms of the operation of natural laws.  And natural laws can often be shown to derivable from simpler natural laws.  (E.g., that's why physicists are on a quest to unify the four forces of physics ... so that all laws of atomic physics can be derived from a single law.)  However, scientists will always be faced with the question of where these simplest of natural laws came from.  And they may have to settle for the answer "they seem to have always been there", which brings us back to #1.\n\n#3, and #4 need more definitions to distinguish them.  What do you mean by phrases like "beyond nature", and "intelligence."  \n\nHOWEVER, despite being a died-in-the-wool evolutionist, I lean towards #4, (an intelligent, supernatural origin for all things in nature) but not with in the same sense as Intelligent Design.  I *don't* believe some intelligence designed every cell membrane, every flagellum, every eyeball, every bird, bat, or insect wing, every endochrine cycle, etc.  Evolution provides a far more satisfactory explanation for all those things based on such simple natural laws as the law of natural selection.  \n\nBut I do wonder where that force of natural selection, as a natural law, came from.   I believe it will be shown to be derivable from simpler laws of chemistry and thermodynamics, which can be derived from even simpler laws of physics.  But ultimately, we will still be faced with wondering where those primary laws of physics came from.

It's relative. There would be no life AS WE KNOW IT. But that's not to say an alternate form of life would not have developed. Who knows, the universe is astoundingly big.

Yes, because one of the characteristics of life is the ability to replicate, or reproduce, and they definitely do that.  Another is the ability to move freely and independently, and they also do that.  Check the website below for other information.

A very legitimate question - despite most of the answers posted here.\n\nThere is no way that this question can be answered.  Science will never figure it out.  This is in the realm of philosophy and metaphysics.  Whether the answer is God or some other explanation there is no way that we can ever definitively know.  When it comes down to it, you can believe in God or some other explanation, but ultimately it becomes a matter of faith. \n\nQuantum physics postulates that particles can be created out of the void.  That really begs the question of "why"?

No.  Obviously life exists despite the second law of thermodynamics.  The chemical processes associated with living organisms use energy from the surrounding evironment to create more order.  Our evolutionary ancestors did that too.  I see no way in which evolution contradicts the second law of thermodynamics any more than the existance of life does.

If a mathematician is talking about life, he/she might be talking about the game of life. The game of life is played on a infinite grid, and there are some cells to start with. There is a simple rule to decide how a cell is born and dies. It generates pretty patterns. \nThis game seems to be pointless, but it is closely tied to chaos theory and cellular automata, which helps to solve very difficult calculus problems.

So far, science knows that in every life there is oxygen and protein or amino acid but other constituents are not known yet. Hindus believe that there is a life energy which is a property of Nature that is more vital than the material property as detected by the modern Science.

The origin of the first life form is actually indeed unclear.  What makes this so difficult is not that one cannot envision molecules that replicate themselves by having certain enzymatic activities.  Rather, if all recent life forms go back to one ancestral species, how did all those parts shared by recent species come together?   (For example, cell membranes, organalles, the nucleic acids etc.)\n\nNow, you are absolutely right that there is an assumed parent species, an ancestor to all other species on the planet.  But science does not show at all that life cannot derive from non-life.  Quite on the contrary, science would suggest, since all the individual parts of which living cells are composed are by themselves not alive, life must emerge from the higher-level organization.  The idea is the following: the properties of the parts of a system do not predict the properties of the whole.  Take water, which is composed of two gases.  Nothing in the properties of either gas suggests or makes predictable that H20 is a translucent liquid with a density anomaly.  The same holds true for biological systems.  Life seems to emerge at one point of complexity as a property of the union of non-living parts in complex systems such as cells.  How that happens is unclear.\n\nNow, I am not familiar with the theory you mention.  As a biologist who has focused much of his work time on evolution, I cannot say that this is a commonly held opinion.  But your question is a very good one:  If that indeed were the case, don't we just push the point of origin one level backwards?  Some scientists opt for the pansperm theory, according to which life came from out of space.  Not to wory, I am not talking UFO's etc.  Rather, amino acids and nucleic acids have been found in space.  The idea comes in two major flavors, namely one, that life originated on earth from these parts that were brought to the surface of the planet by means of meteors and then came together to form life.  The other flavor is that this happened on another planet and that the living cells were transported by meteroites to earth, which likewise would push the problem of the origin of life backwards, just as the "other dimension idea" (which to me seem rather strange and unscientific).

I don,t think that Physics TALK TO PEOPLE who HAVE DIED. But I can't say it with authority, b'cas miracles are always the way, physics has expressed itself.

I think so!\nIf life exists on the top of the large mountain where there is only snow and no oxygen in the air, then life should exist on other planets!\n\nDo you know that, life exists in deep sea where there is no sunlight! If life sunlight to live, how do you explain?\n\nLife also exist in caves very down in earth where no light is present. They are bacteria! They absorbe heat from boiling water, thats how they obtain their energy!\n\nThat may be quite enough to explain how life may exist in extreme conditions and thus beyond planet earth

There is no other explanation for plant life.\n\nThere is no other explanation for animal life.\n\nThere is no other explanation for YOU, \nthe entity that lives in a flesh body.\n\nThere is no other explanation for Earth,\na planet that supports all this life.\n\nThere is no other explanation for the universe.\n\nThere is no other explanation except God and His Word.\n\nThere are only man's theories and conjecture.\n\nMan a very fallible entity.
