quotation by physicist
Posted by Jon on 7/8/2010 6:19:26 PM
I prefer the way Carl Sagan said it: The Universe is all that is, or ever was, or ever will be. Our contemplations of the cosmos stir us. There’s a tingling in the spine, a catch in the voice, a faint sensation as if a distant memory of falling from a great height. We know we are approaching the grandest of mysteries. The cosmos is within us. We are made of star stuff.

if we are made of stardust,how are the world-wars are thrust upon us ?

@sastri No. Just No. Okay? No.

I don't have much use for wars but they're part of the picture as point counter point yin-yang and the billion other contraries assembling in our plane. War has poetry too, sad and realistic with very few aged men. While suicide is rarely recommended the potential hero is supposed to select more and more difficult enemy until...around 40...

everyone should tell me why this matters. Within the realm of physics this is true. We are made of stardust. In the spiritual realm they will say that humans were willed into existance. However, in my personal view, everone should shut up and appreciate what they have. In the end we all have the same ability to think and create. How about all of you 'opressed' assholes go out and do something worthwhile for those less fortunate and quit whining about how hard you have it.

The Human body is made almost 3/4 of water which is 2/3 hydrogen. Hydrogen (which is about half of a human body at ~49%) is the most common element in the universe and does not require fusion within stars. To that end, "every atom" really means, "a little mor then half the atoms." Still poetic, but misleading.

People sure enjoy bRagging about how smart they are compared to others. That is why the concept of God is so unpopular.
Posted by Defiant John on 2/22/2011 5:51:24 AM
@not technically correct...so, what's the rest of the body made from? Elements exclusive to Earth?
Posted by cassuduh on 2/23/2011 3:50:04 AM
There are no elements exclusive to Earth. Save for possibly some man-made ones. Every thing we are comes from exploding stars, as they die the send out bursts and become more compact, causing the atoms to condense and changing what the bursts send out.
Posted by Actually.. on 2/23/2011 9:57:58 AM
@cassuduh, not technically correct...the body is 3/4 water. so that means its half hydrogen and 1/4 oxygen. so theres only 25% of the human body left for discussion of what its made of. so maybe we got stardust in us somewhere, but i doubt the human body is composed of 75%water and 25% "stardust" youre dumb
Posted by jimmy on 2/24/2011 2:45:12 PM
Defiant John...the concept of god is unpopular?? Really?!?! Something like 80% of the ENTIRE WORLD is religious and believes in god and that's unpopular? Man i'm sick of majorities trying to pretend they're oppressed minorities

I liked another way I heard it put. You may be made of molecules of Elvis Presley's turds or dead dinosaur carcass or both.
Posted by Guy on 2/24/2011 10:02:49 PM
To: not technically correct Stars actually go through fazes converting elements from one to another through fusion, so a H atom is converted into helium, and this continues to occur, becoming denser and denser material. This happens until they reach extremely dense elements such as zinc. So a star exploding could contain a number of elements, not just hydrogen. Further when organisms ingest or use materials they have the ability to change them from one element to another. In short just because you have an atom that is hydrogen, doesn't mean it was always such so every part of you did come from a star. Solar systems are the result of star collisions and explosions so we all of our ATOMS were once a part of a star.
Posted by Gangg Star on 2/24/2011 11:41:45 PM
To: Reality That number of 80% is no where close to correct. I know thats not the point but still... use factual information, oh and even if 80% did believe in God, that still doesn't mean squat. I'm not gonna pull a number out of my ass, but a large percentage of the population of the entire world once belive the Earth was flat even when all the information needed was infront of them, as it is for religion.
Posted by Gangg Star on 2/24/2011 11:45:50 PM
well. you are all wrong in some way or another. 1)considering that about half the population lies in china and india...2 of the most religious areas of the world, it may not be 80% but it probably is somewhere close. 2) stars begin by the gathering of hydrogen AND other atoms from a former star. they GRAVITATE toward each other because of that little thing newton discovered called GRAVITY. from there towards the center where the atoms and molecules become more dense they form a start. and as these atoms begin to collide with such force they fuse together and once this happens at around 5000 K you have a star and so on (if you don't know, go find out for yourself what hydrogen atoms fuse together to create, it requires 3 of them). the other matter that has not traveled to the newborn star begins to collect and collide with each other and yes there is dust and other particles. these particles gather together and grow and grow until you have planets form....thus you have a solar system most likely similiar to our own with inner planets probably being terrestial and the outter most likely jovian. if you don't understand that, go look it up. keep it mind that it requires a great stroke of luck for this all to happen. and most likely it won't. but seeing as the universe is about 13.5 BILLION years old there a vast number of planetary systems our there much like our own. We have even begin to believe to found other planets in the "goldie lox" zone, again if you don't know, look it up. and whoever spelled "PHASES"...."FAZES" please go back to school where ever you graduated from and return your diploma as you should probably not have one.

why do people feel the need to be assholes? it's a very interesting topic, an intellegent person should know how to be polite. you can be nice and prove a point at the same time you know. life is a learning process not a constant debate.
Posted by Daniela on 3/1/2011 4:43:36 PM
A few of you seem to be confused. Stars are made mostly of hydrogen, but there are other elements in them too. In fact, every element in the periodic table up to iron. Nothing past that forms during the majority of a stars life because fusing iron to make something else requires more energy than it releases. When a star goes supernova, the iron core of the dying star collapses and forms the elements that are heavier than iron. So what I'm trying to say is 100% of you is from what used to be a star. That's a fact. Oh, and to the guy who said 2/3 of water is hydrogen, that's only true if you're going by atoms. It's really 1/5 if you're going by mass, which would be the more appropriate way of expressing the percentage of hydrogen in a compound.
Posted by Hey on 3/1/2011 5:01:59 PM
This quote shouldn't begin any sort of religious discussion. Some people believe God(s) made our world, some don't. The fact of the matter is, we can confidently theorize that our solar system is a newer solar system, and we're observing other broken-apart (dead) stars contributing to new systems. Therefore, we can say the atoms in our bodies were once atoms in another solar system, vaguely like how the water we use now is the water we've (not necessarily humans)been using for centuries and centuries and centuries. That's an amazing idea, and that's why this is an amazing quote.
Posted by Paradoxasaurus on 3/1/2011 5:10:46 PM
I think it's really thought-provoking how such a beautiful quote like this can inspire all this debate and mud-slinging and nasty words.

Its true, carbon and hydrogen were not common in the universe after the BB. In fact only lithium and helium were present, the elements that make us up could have only come from the fusion inside of stars.

You know, turds are made of "starstuff" too
Posted by bittramp on 3/5/2011 7:48:26 PM
@ Gary, true, it is more poetic. But not quite as to the point. @ sastri, what does being made of stardust and world wars have to do with each other?
Posted by Britt on 3/6/2011 12:41:00 AM
Ummm... water can't be starstuff? What? water is Hydrogen and Oxygen... which, as I understand it, are both contained within Stars... So I don't know where you get the "water doesn't come from stars" yes, water doesn't... but the stuff that makes water does. Talk about Obtuse...
Posted by Ruspar on 3/6/2011 2:44:49 AM
While I'm not a professional physicist (probably like the rest of you), I'm fairly certain that Steven Hawking stated that this IS technically correct on Into the Universe. How this started a religious debate is beyond me, but I'm certainly not as gifted as, say, Steven Hawking?

Posted by SarasAra on 3/12/2011 2:54:41 PM
@gangg star: People didn't believe the earth was flat. That's a myth created by a group called "The Flat Earth Society" who want to show that misinformation is often taken as fact without any basis of truth. To support this further, many people think that the Flat Earth Society is a bunch of people who STILL think the Earth is flat! lol. Another good example is that: "We only use 10% of our brain"...that was in fact created by advertisers for a TV commercial (for a car, I think) yet many people quote it or believe it to be valid. Vic Reaves said it best with "92% of statistics are made up on the spot, the remaining 23% are made up afterwards".
Posted by redmistpete on 3/15/2011 6:56:11 AM
Please give up on the whole "God made everything" argument. It's an outdated, archaic idea that should've died a long time ago. Shame on you for blindly following what your parents/church told you to believe. Do humanity a favor and think outside the church, we are all intelligent humans here, for the most part.
Posted by Chelsea on 3/17/2011 7:20:55 PM
Hmm... After Big Bang there was only hydrogen. Hydrogen atoms eventually formed stars that fused hydrogen into heavier atoms such as Helium, Lithium, Carbon, Oxygen etc. At some point the stars runs out of fuel and will gradually expand and then collapse. If the collapse is fast and strong enough it will form a Super Nova. In this formidabble im/explosion, heavier elements will be formed. So - appart from the Hydrogen in our body (every single molecule in our body contains Hydrogen in some amount) every other element is the result of dying stars. And ONLY nuclear reactions can change elements. Please feel free to believe that God made all (or only us). I for one don't care.

@not technically correct, ...hydrogen exists in stars too, even supernovas still have hydrogen in them.

we exsist be it in this dimension or rather a different one in which we had the ability to create this, it's still fun. stop hating. quotes are cute. that one is too and it has some logic leave it be. unless you reallllly are a genius and have figured out all we all ended up here?.. yah c'mon and inspire now.
Posted by jessica on 4/6/2011 4:18:14 AM
@not technically correct You sir.... are not technically correct. Stars fuse hydrogen and helium. The fact that hydrogen does not need star fusion to exist doesn't mean the statement is incorrect. It merely means the statement is correct in a different way than you are perceiving it to be. Please just appreciate the quote and move on instead of pointing out the fallacies in your own logic. Also, if you want to get scientific you should probably know that 2/3 of water is not hydrogen unless you are talking strictly about the fact that there are 2 H's and one O. If you look at mass or any number of other measurements that REAL scientists use you would know that you are far from correct.
Posted by Come on Dawg on 4/11/2011 8:33:35 PM
Here's the deal. After the big bang, it's thought the only elements were H, He, and Li...no others. So the early stars started from only those 3 elements. The heavier elements were created within those first stars fusing together the original light elements in heavier ones. A few billion years go by, the early stars go nova, and scatter their now-heavier elements...which eventually recombine into planets, and thus us. So yes, the elements within us heavier then H, He, and Li, were created many billions of years ago within stars.

where did the big bang come from. Infinitesimal mass and density that came from where? The laws of physics the big bang is based on was created by who? The force that caused the reaction of the big bang was created from what? What was before the dense mass that exploded and created all the stars, it just was? God created the big bang

The argument has deviated from its original defined path, therefore creating chaos and possibly another big bang will invariably change the thread. Can we be focused and create a lab test scenario and leave it at that?

I almost enjoyed reading these comments more than the quote itself! It's amusing that Human Beings bicker about the seemingly most insignificant things...but as they say, history repeats itself, we will always argue about those little things. However, I really enjoyed some of the arguments set forward. As for the argument about God, this site is called PonderAbout, if you can't read comments that suggest "He" doesn't exist without getting butt-hurt, don't comment. If you can read those with an open mind, good for you, you're one step closer to being a functioning member of society :)
Posted by Stephen on 6/2/2011 1:45:28 PM
God is an outdated concept, created by archaic people who had the need to explain things they could not explain without making shit up. The God concept is nothing more than mental laziness and maybe even lack of courage.
Posted by universal on 6/2/2011 3:52:07 PM
I fail to see how people can expect their pseudo scientific ideas to be taken seriously, when they can't express themselves correctly. To quote "Further when organisms ingest or use materials they have the ability to change them from one element to another." What is this ability you speak of? Which organisms are these? As a corrollary to the "we are all made of stardust" quote I would submit that EVERYTHING is made of stardust. As to 'who made what' does no one see the cyclic nature of reality?

Until somebody physically flies through space and picks a piece of a sun and brings it back to me, I will continue to hold that all "knowledge" on the topic is strictly speculation.

These comments are hilarious! Another quote I found on the same topic said this: "There's a joke among cosmologists that romantics are made of stardust, but cynics are made of the nuclear waste of worn-out stars." From 'Journey to centre of the universe' by Joel Primack and Nancy Abrams, 2006 I like the idea that good blew up to create the big bang to detramental.
