if we find microbial life on another planet, how long will it take to evolve? 5 billion years?
Stellar
You're looking at evolution the wrong way. Simply put, evolution is rather a constant process... meaning the microbial life would be constantly evolving. Its not as if, 4 billion years later you cant say its "evolved" but 5 billion years later you can...

so what your saying is that evolution is taking place all the time, that seem kinda wierd if you think about, i was reading national geographic the other day and saw the thing where we are all suppose to be made from the black woman in africa and all the different kind of people are just mutations of that woman.

That's called microevolution...Mutations, Genetic Drift, and other factors all affect microevolution...

Evolution is a complex idea, as there are different kinds...Like punctuated evolution.

You can understand more in a College level biology textbook...Even AP Guides.

In biology, evolution is a process by which novel traits arise in populations and are passed on from generation to generation. Its occurrence over long stretches of time explains the origin of new species (speciation) and ultimately the vast diversity of the biological world.

A nebula is energy, it may be also life itself or conciousnesses. Our version of early life is only ours.


I read somewhere from some book that some life or planetary systems hold everything in constant decay, others as a crsytaline structure. Many different ways of life. The book was spiritualist etc.

Do you know the unlikelyhood of this? There are other ways of evolution...divided into two major grouos. Macroevolution and Microevolution. Each have different types of evolution, including mutation, polyploidy, genetic drift, gene flow, bottleneck effect, allopatric speciation, sympatric speciation, Natural selection, etc.

You are wrong here. Air is a mixture of different gases. Gases don't change states or turn into different compounds/element unless catalysed by energy (ex: electricity) or other reactions. Air is not energy no.gif tongue.gif

Matter
Something which occupies space and has mass.

Indeed they are. Half way through a grade 11 science class you learn m=E, but E does not =m. Its a case of "If all Johns are blobs, and some blobs are zorks, are zorks Johns?" You know... a common IQ test question...

Matter, as you've shown, is something that occupies space and has mass. As we see in the equation E=mc^2, (c being the speed of light), mass does equal energy. A certain amount of mass is the equivalent of it times c^2 of energy. Seeing as matter in a nuclear reaction releases energy (at the elimination of the matter), it is indeed energy, just as frozen water is still water.

Another simply way to see this is to ask yourself what is matter made of? Atoms, ok... but keep going... what are atoms made of, and then what are the subatomic particles made of, and you'll end up eventually with the answer "energy".

The total amount of energy within the universe is constant. If you annihilate matter, the result is energy. Seeing as the energy can not be created, and the total amount of energy in the universe is still the same, the matter WAS energy, but highly organised.

Still not convinced?

Stellar, below are some quotes from the links you provided.

From the first link:

QUOTE
"Now there is one law called the law of conservation of mass-energy. This allows for energy to change into mass and mass into energy while keeping everything constant."


Notice it talks about changing mass to energy and vice versa, the implication of this is clear, they are interchangable but not the same. Note also that it is the "law of conservation of mass-energy" not the "law of conservation of energy."

From the second link:

QUOTE
It followed from the special theory of relativity that mass and energy are both but different manifestations of the same thing.


The emphasis on the word different is mine.

From the third link:

QUOTE
the formula E=mc2 only showed the theoretical possibility of converting matter into energy.


Again one can be changed into another but they are not the same.

Your statement:

QUOTE

is the equivalent of saying that houses are made of bricks so a house is technically a brick. This is a false statement. (How did you do on that common IQ test by the way?)

Air is made of matter which is as you said made from energy. That is correct but it does not follow that air is therefore energy.

I have no need to argue with Einsein, he and I are in perfect agreemant on this.
RamboIII
i think a lot more could get done if we didn't take every argument personally...(myself included original.gif ) but im going to have to go with waspie on this one. Air is not energy, that is just silly, but it is very true in stating that air is capable of producing energy and that air can be used to carry energy, for lack of a better word.

That is because they are different "states" (for lack of a better word) of the same thing. I can chance ice into water and water into ice, but ice is still technically water.

From the same link where you got that quote, it clearly indicates "Actually, energy is matter, and matter is energy."

QUOTE

The emphasis on the phrase "of the same thing" is mine.

It clearly says that they are the same, the different pertains to their "state" again, not to what they are.

Are you a good fisher?

That is because they are different states of the same thing, as the two previous links have shown. From the third link:

Convenient of you to leave that out...

Nah, thats quite rough. Its more along the lines of "This house is made of bricks, so technically, it is a bunch of bricks." Its perfectly valid, no? It indeed is a bunch of bricks, but with a certain order to it. One could almost call it "two different manifestations of the same entity"...

QUOTE

(How did you do on that common IQ test by the way?)


Ive only ever taken online IQ tests, and as expected, they ranged between different values when I took them 4 years ago. If you still wish to know what my scores were, go ahead and tell me.

You:

You make the implication that thus matter is not energy.

He makes the implication that air, having a mass, is thus energy.

You seem to think that being different states is unimportant, but it is all important, Ice is made from water but it is not the same as liquid water. Same components totally different properties. You can not argue that an igloo is made of liquid water. (Your choise of water in this example is not really a good one as water can refer to both the liquid state and the chemical in any state, hence to make the analogy more accurate I refer to liquid water).

I suspect we are going to have to agree to disagree on this before we totally hijack this thread and take it totally off subject.

QUOTE

That is not a mistake, as I have proven. To say otherwise is to argue against physics as we know it.

I do also say matter is comprised of energy, because it being energy means that it is made out of energy. Ice is comprised of water, for example, because it is water.

QUOTE

But I did not mention liquid water, I quite simply stated water. Ice is water, plain and simple, and thats why the state is unimportant. It doesnt matter what state its in, its still H2O, just like matter is energy.

QUOTE

Actually... I can argue that. I was under the impression that an igloo was made of frozen water... wink2.gif

No, the analogy was perfectly thought out, and technically, water is not liquid water. Water is any state of H2O, but is commonly used to refer to the liquid state.

Please do.

This is the fastest moving subject I have seen since the Roswell thread died.

Seriously though, this is fascinating and the two should not have to agree to disagree. This should be resolvable with the available resources.

I am in total confusion, I would agree with Waspie in a heartbeat normally as E=MC2 makes two sides of an equation which are proportional. If proportional to each other, how can they be the same thing? Energy is active mass is static?

But Stellar makes an excellent point that breaking down matter enough will provide minute but moving particles. To be moving, it must posses energy.

So, does mass possess energy or does mass comprise of energy? Are they symbiotic?
How can E=MC2 if mass is energy? Mass cannot be mass multiplied by the speed of light squared???
Is mass a combined and slower form of energy? (considering Ice molecules to water molecues) Ice is water but exhibits different properties. Can water=ice x the speed of light sqaured?

Hell now I'm confusing myself. wacko.gif

rapid7

Interesting debate. Is this the middle ground?
Matter is made of potential energy?

Does light have mass?
The short answer is "no", but it is a qualified "no" because there are odd ways of interpreting the question which could justify the answer "yes".

You're kind of on to it. Ice is water, but in a different state. So is mass. Mass is a more "organised" (As I'd qualify it) form of energy.

The fount of knowledge is adequate in the preceding answers, but I would just throw this in.

The Earth took about a billion years to cool down from its fiery and tempestuous beginning
(radiating heat, meteors and astroids, volcanoes, atmosphere development). Then you had, possibly the first living cells become active from the available input of rich reaction evironments during that cool-down phase. To go from the beginnings to those simple variations was probably some few million years. As time went further down the road, the different living organisms evolved, with a few major "extinction" events (which have interesting cosmic origin possibilities). All together, a technological, bi-pedal rocketman took 3.5 billion years.

Can that be accelerated, to conceivably allow for a shorter time-frame? Sure- take out the competition earlier, while allowing enough competition to spur development.

I could vaguely imagine symbiosis on a grand scale augmenting evolutionary time periods, but have not given that any real thought.

Energy and mass are interchangable but not identical.

You do realise that theres a difference in measurement between energy and mass, correct? You do not say something has "1 kg of energy", do you? Just as 1 km and 1 mile are both distances, but theres just a difference of measurement. As for energy not being identical to mass... tell that to Einstein:

"In his article of 1905 Einstein proved that matter and energy are identitcal."

Mass and energy are different manifestations of the same thing because matter is energy.

From the Nova tv web site, Einstein's Big Idea:

QUOTE
First, though, a capsule explanation of "energy equals mass times the speed of light squared" might be helpful. On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing. Under the right conditions, energy can become mass, and vice versa.


"Different forms of the same thing" in the same way that ice and steam are different forms of the same thing. But in the same way that ice is not steam, mass is not energy.

I say it again, Energy and mass are interchangable but not identical. Air is not energy it is matter.
Stellar
QUOTE

"Different forms of the same thing" in the same way that ice and steam are different forms of the same thing.


Precisely. Different forms of the same thing, meaning they are the same, meaning mass is energy, but in a particular state. Its the equivalent of saying "water ice and H2O are the same thing". They are, but ice is in a particular state.

Again different manifestations. This is known as the equivalence of matter and energy. Equivalence is defined as being equal in value, that does not necessarily mean identical. If mass was energy you would not have to annhilate the mass to convert the one to the other.

These seems to be where you are getting confused. "Energy" is not a term pertaining to a certain form, energy is more of a blanket term. We are not saying that "mass energy" and nuclear energy are the same, (that would be the equivalent of saying ice is steam, since its comparing two different forms)... I am simply saying (as physics also states) that mass is energy (which is the equivalent of saying liquid water is H2O, or water steam is H2O).

Einstein clearly says "identical" though. Why? Because energy is a blanket term, which covers mass as a form of energy.

Untrue. That is simply a coversion from one form of energy into another, similar to electrical and thermal energy.

How many times do you want me to quote physicists and Einstein? Mass is a form of energy, whether you like it or not. It fits the definition of energy to the same degree that light fits the definition of energy.
Waspie_Dwarf
It seems to me that we are arguing over semantics here. It really comes down to interpretation of the term equivalence. I have been looking into this further and it is possible to justify both our positions.

It can be said that matter and energy are two different aspects of the same thing, but it is also true to say that one can be converted to the other ie not the samething but interchangable. Even the quote from Einstein,
QUOTE
It followed from the special theory of relativity that mass and energy are both but different manifestations of the same thing

It followed from the special theory of relativity that mass and energy are both but different manifestations of the same thing

If we carry on we are going to go round and round and never agree, despite the fact that really we agree on more than we disagree on. Interestingly on one site (which rather stupidly, as it di not back up my position, I forgot to note down its address so I can't give a link) there was a feature on the philosophy of E=mc2. There was a similar debate to ours and no definative answer was given.

So as I said earlier I think we will have to agree to disagree on that.
