Our universe is a beautiful mathematical object that came out of nothingness about 13.8 billion years ago, whose energy was born out of the dancing virtual particles quantum fluctuations are, and whose total energy is zero. So we are made up of quantum fluctuations, which appear everywhere all the time; we are the children of stardust and supernovas-all atoms in our flesh and blood and brain are star stuff. With every breath, we are breathing the atoms breathed by all living things on Earth for 3.8 billion years. Thus, when we realize our cosmic origin, there is no room for hate, bloodshed, and depression; no room for wars, tyranny, and exploitation; and plenty of room for limitless love and happiness. We are star stuff and don’t need religion or gods or holy books to tell us that. There’s a revolution in science that began with Einstein and is spreading like wildfire into the 21st century thanks to technology, a revolution that will shake the very foundation of our cherished philosophical and religious beliefs and will turn them topsy-turvy-the realization that baryonic matter is just 4.9% of our universe, that there’s an immensity permeating it that is 26.8% of it (dark matter), and even a greater immensity that is 68.3% of it (dark energy). Our universe always bends to the will and wishes of those two dark forces. How wonderful is the tide of time we’re surfing! Here’s a cool 1:49 video (Sloan Digital Sky Survey): www.sdss.org/science/

"Dark Energy" is a really nice side-step and "tap-dance" to explain "how come there's so much energy and so little matter?" The answer is obvious. "Energy is neither created nor destroyed...rather, it is actualized and made manifest by the inter-actions of matter"

Greg Aldering starts with 1) extrapolate cosmologic distances by brightness of star 2) concept of peering back in time when the light reaches us and 3) concept of the stretchiness of space as a function of the shift in the wavelength of light. I dont entirely understand the 3rd concept... how you can infer that the wavelength of light would shift if space stretches. In other words, what is the evidence that an expansion of space would expand the wavelength of light that was contained in that space. Could space expand and the lightwave remain at the same wavelength? How could you ever test this?

2 questions: the dark areas in the map of the galaxies seem to be confined by straight lines. Are those areas areas that haven't been mapped yet or is this the way of how the map is depicted? other question: how do we know that the expansion of the universe is speeding up when what we are looking at is the past of the universe. Maybe the galaxies back then moved much faster than now and the expansion - right now - could instead be slowing down or has the time factor been taken into account (which I assume)?

There is something I do not quite understand. We learned that "the farther away the galaxies are the faster they move away from us (and each other). So at, let's say at 1 million light years distance the galaxies move slower away than others at 10 million light years distance. And the conclusion also is that, due to the constant speed of light bringing that information to us, we are looking back into the past (the recorded information of the past). Question: Doesn't that also tell us that in the distant past galaxies were moving faster away from each other (faster expansion of space) than they do more recently or now (slower expansion of space)? How then does one come to the conclusion that the expansion of the universe is accelerating when the opposite seems to be the case? Or have I missed something?

Yes the space time continum can expand faster than light can travel through it but if it's stretchiness varies from point to point and from time to time then aslight passes through those reagions it stands to reason that the wave propogation speed might vary just as the wave speed in a string varies with the tension in it. We would not know this because all of our detail measurement on the speed of light are made locally.

+Vernon Brown if you get an elastic band and put dot on it at equal distance and then stretch it slowly you can see the distance between the dots grow exactly the same way but the distance better the first and the last grows exponentially faster, grows even faster than the speed of light. If I have understood you correctly, you are assuming that the earth is in the middle of the universe and the universe is expanding away. But the whole universe is expanding equally so the distance between further galaxies are not like as if they are on the surface of a balloon and we are in the middle. A better way of visualising it perhaps would be to imagine the galaxies are shrinking rather than the space expanding. This way you do not assume everything is moving away from a centre.

you see "back in time" because the light has not yet reached us. Einstein found "accidentally" mathematically that the universe is expanding, then later several scientists found the same results. Thing is the universe did not expand faster before (as far as I know) and at some point dark energy forces became larger than gravitaional forces, meaning that the larger the the universe is the faster the expansion is, i.e. eksponential growth in expansion. Correct me if Im wrong here anyone :P

One fundamental fact about our universe is that : High pressure always gravitates to low pressure. E=mc2 correct ? What does -E= ? When energy creates our universe it needs no dark energy to continue its expansion, simply because it is liken one of those coin funnels. As the coin approaches the center of the funnel it accelerates. We are expanding because, we are falling apart, into the lowest possible pressure 0, or "True Emptiness (sometimes confused as god etc). Energy can be measured. Non energy cannot. Our universe was born from a singularity, not a duality. This process is what developed into various vibrational currents. Every atom is made of space/void in which particles vibrate, and work off each other thereby creating a duality that is the basis for all false beliefs. Like the oceans that accept all of earths water. This is where the water comes from and it is where it all goes. That is also why everything is empty, and emptiness is the source of all things.

What do you mean by 'pressure gravitates'? E=mc^2 does not say that. This formula explains how energy (E) equates to mass (m) and how much energy (E) is would be release or generated when matter converts to energy. What does that have to do with 'pressure gravitating'? And furthermore, how can emptiness be the source of anything? What you are trying to explain is not the physics that I and most of us have learned about.

Hi, can someone please answer my question? Why does everyone continue to assume that the propagation of photons (aka the speed of light) is constant for all instances and through all mediums? It's not. The speed of light through glass is slower than the speed of light through air. The speed of light in the vacuum of space is MUUUUCH faster than the speed of a photon inside a hydrogen atom during a state of quantum transition (~300 M/s vs ~300,000,000 M/s). SO WHY DOES EVERYONE CONTINUE TO ASSUME THAT THE SPEED OF LIGHT ITSELF IS CONSTANT? IT'S NOT! It changes all the damn time depending on what you're sending that light through. E=MC^2 can be re-written as: M=(1/C^2)*E. If we hold our ENERGY level constant, and assume that C is variable, we see a vertical asymptote at 0. This is telling us quite simply that we will NEVER achieve a state of absolute 0. Absolute 0 by definition is the state at which all molecular motion has stopped. If this is true, then matter cannot exist because matter is a function of the relationship of ENERGY and the speed at which LIGHT propagates. If there is no energy moving, there is no MATTER!

It is first time I saw this presentation. It explains very clear. I have an...idea that there may be negative Gravitational CHARGES (not negative mass), which might be carried by positive mass. In regular positive mass universe, positive mass carry positive g-charges. Negative g-charge attract each other and repel positive g-charge. Negative g-charge theory predicts a jerk expansion of the universe.

+Sayilen Radhakrishnan No we wouldn't because the gravitational forces between the stars that make up a particular galaxy dominate over the dark energy. On larger, intergalactic scales however, the dark energy dominates over gravity because of the huge distances involved between galaxies, meaning gravity is comparatively weak within these regions as compared to within a galaxy. Hence we only see the intergalactic regions expanding - not the galaxies themselves.

And since there is a lot of so called ‘empty space’ between all the stars in a galaxy, the Milky Way and Andromeda will merge and then pass through each other (with a lot of gravitational interactions changing the topography) like a pair of ghost-like dancers in a gravitationally locked embrace. I don’t think there will actually be much colliding, as in an automobile crash but clouds of gas will collide and heat up and cause some shenanigans. And then there is the eventual merging of each galaxies central super massive black hole. But don’t take my word for it, keep watching talks like this.

excuse me Im no mathematition but I have a thought;which is actually very funny.Its this dark energy is thought I mean when we think we are converting our body fuel into energy because I think a thought is pure energy.and if so it takes up space but when youre through with it where does it go i mean we have no place in our anatomy to store them or our memories and ive heard said when we are in the realm of memory we are in the spiritual realm but let me get this right since every thing is god and i believe we are only here to expand the mind of god it would be the same as the universe and since thought is energy and cannot be lost it has to be somewhere and ill bet that if you could measure a thought and add them all up the size of thier expansion growing with size of the population and thier intelliganceincrease would be proportional to the size of the expansion of the universe but i couldnt put the numbers together to prove it . i hope thats clear enough for some one to understand what im pointing at

Our thoughts are electrical impulses, and they are dissipated in the form of heat, so if our thoughts are having any influence outside our bodies at all it's global warming. Look at the Mall of America, located in a cold climate yet has no heating system, as the people inside provide plenty of heat to keep it warm.

+Oners82 ......... It's so simple common sense that expanding space will have energy to it, does anybody really need to prove it to claim a nobel prize ?

+Chris Skinner ........ They say there is no perpetual motion machine. But what if we are living inside one, or more specifically, a perpetual expansion machine ? Expanding space-time will exert an outward expansive space pressure, which will continue to drive even more expansion.

+Oners82 You are laughing. But I came up with a theory that explains everything and manage to find a way to prove it. When I discovered it, about 10 years ago, my understanding of all the physics and universe changed. I could not believe how a simple theory solved almost all the problems in physics. Since then every prediction I made came true. I am 100% sure I have found the unification theory. You joke and say you win the Nobel prize if I have found it, but after writing to every scientist I could think of, writing to editors, lecturers and academics, no one showed any interest to even hear me out. If fact telling anyone that I have found a theory provokes the most hostile reaction. I am wondering if they will bring stoning and capital punishment back for people who claim they have theory. I mean someone innocently wrote just one like trying to share his idea and you ridiculed him. What chance do I have to prove my theory. They don't listen to me, if I write a science paper they will bin it and if I write a book I won't make any money from it. The solution is simpler than you think. All these scientists study few books just like we do, they sit down and think, just like we do and they put 2 and 2 together and come up with a theory just like we do. Most of them talk complete nonsense and they know it, but since they are a title next to their name everyone listens to them. Einstein made wrong predictions and did not believe in Quantum theory until he died. So is he a crackpot? There is no such thing as a genius All you need is three thing. 1. Understand the problem, 2. be at the right place at the right time and 3. recognise the solution if you see it. Anyone can do it. All I need is for them to give me a chance for me to do a talk for 2 hours and I will assure you I will convince them what dark mater, dark energy and gravity is and at it will solve 20 other problems.

+Jason987262 This is one thing I do not want to disclose. They spend billions to research these things so I am sure it is worth a lot of money. I have been looking for someone knowledgeable and very enthusiastic to team up with me and prove this. It is no just a theory of gravity etc, this theory applies to everything, I mean it clearly explains the quantum world in a comprehensible way, and solves all mysteries of physics, it explains evolution, biology, psychology, economics, etc. This is the rule by which everything works. It is not an abstract idea like String Theory, I have used it for over 10 years and it clearly solves problems. Interesting enough, I discovered it by studying the mind. I am a software engineer and my ambition is to make a concious AI machine, and have made a lot of progress and have solve the key problems. The breakthrough came when I discovered that since we perceive the universe through our thoughts and the universe we see is not what is out there and therefore most of it is undetectable to us and all the laws are relative to our understanding, so to understand the mind we have to understand the universe and to understand the universe we have to understand the mind. That is why there are so many mysteries in physics and mind. I am sure with some technical help I can win the Nobel Prize by solving the problem of gravity and Dark matter etc, but the big fortune is in AI. So if I can prove the physics problem and get some prize for it then I can create the first concious machine in few years. Visit my website www.ordoukhani.com. You can add me to facebook and then we can discuss this. Thanks for your interest.

My Above reply was for the 1st part of your comment, up to the Space Time part about a paragraph down. Then I wrote the above reply, and then finished reading your comment. Some very good observations you have gleaned. Many of those are some of the major hurdles that all the "Currently" well liked theories have in common between themselves. I personally, see no evidence of Space-Time, as both are constructs of our unlearned minds. What we do see as evidence of them is again misunderstandings do to the limited comprehension of the one looking. But when it comes to the two forces we are absolutely sue about being in the Universe and Everywhere is that of Electricity and Magnetism. With those 2 forces, there is no need for things like Relativity, Gravity, Dark Matter, or Dark Energy, are all things that are shown for what they truly are, which is just the imaginative thoughts that have no foundation in reality.

yep, Einstein plagiarized it Ruthlessly. This is well known for anyone that has a solid background in the research. Problem with Light and C, being Light speed is not a constant speed, this is known, but its always poo pood. Like you, I used to believe in what I was being told, but when I finally decided I had to look for myself, it didn't take long to realize what a buch of crazy insanity that was going on. To one that is unaware of the details, it always looks possible, but what is happening, is never what it seems. Space Time is a Myth, it is a construct of the mind that is not real.. Space as we are told is a lie, and Time is a Myth, thus Space-Time is a misnomer of reality. Richard Feynman is Still the Brightest Mind in QM and he Died around 87 I think it was.

when matter (or energy) exceeds the speed of sound it goes bang when matter exceeds the speed of light it goes dark and super conductive and I am sure if there was air it would have banged. just an extrapolation no proof here.

Dark matter is the majority of the universe. It is much finer and smaller matter than our protons and neutrons. We are in isolation because of sin, this little universe we can see is all made to isolate us. most created beings are the finer matter that is invisible to photons.
