Can you please answer this physics question?

Can u please tell me what are the question physics has yet to answer on the origin of universe?r?

  • i mean we r close to big bang (we dont know exactly what happened at the time of big bang) we r also thinking of "what before big bang?". maybe multiverse. so what do we need to know more?

  • Answer:

    It used to be that science couldn't answer the question about the origin of the universe or of the Big Bang, but that didn't mean we should make up an answer (such as a god) and say that it was the cause. Within the last few decades science has discovered some good answers. The Big Bang physically cut off any history of what could be before it, if the concept of before even makes sense. A current idea being worked on by some cosmologists is that our universe exists within a multiverse of many other universes -- perhaps an infinite number of them. Each universe would begin with its own Big Bang. Quantum mechanics shows that "nothing," as a philosophical concept, does not exist. There is always a quantum field with random fluctuations. There are many well-respected physicists, such as Stephen Hawking, Lawrence Krauss, Sean M. Carroll, Victor Stenger, Michio Kaku, Alan Guth, Alex Vilenkin, Robert A.J. Matthews, and Nobel laureate Frank Wilczek, who have created scientific models where the Big Bang and thus the entire universe could arise from nothing but a quantum vacuum fluctuation in the quantum field -- via natural processes. In relativity, gravity is negative energy, and matter and photons are positive energy. Because negative and positive energy seem to be equal in absolute total value, our observable universe appears balanced to the sum of zero. Our universe could thus have come into existence without violating conservation of mass and energy — with the matter of the universe condensing out of the positive energy as the universe cooled, and gravity created from the negative energy. When energy condenses into matter, equal parts of matter and antimatter are created — which annihilate each other to form energy. However there is a slight imbalance to the process, which results in matter dominating over antimatter. I know that this doesn't make sense in our Newtonian experience, but it does in the realm of quantum mechanics and relativity. As Nobel laureate physicist Richard Feynman wrote, "The theory of quantum electrodynamics describes nature as absurd from the point of view of common sense. And it agrees fully with experiment. So I hope you can accept nature as she is — absurd."

There's no "before bing bang", just like there's no " more north than the north pole"

There's a handful of questions they want to know: the reason for the values of fundamental constants, proof of the exists of the higgs' boson, proof of extra- spatial dimensions, the elucidation of The Big Bang Singularity (PS: but not in M-Theory since they have brane collision for The Big Bang), and most of all, a rational explanation for quantum theory (PS: but most have given up on this one); that's their list. But the real mystery here: is if you go through life just letting the world community fill you head like a mindless automaton, then how is it, that you can truly understand anything ??? They say it so then it must be so; Hmm REALLY !!! So let me ask you a question: do you think that, if that was the attitude for everyone in science that any discoveries could be made ??? You could never be a theoretical physicist with that kind of thinking, that's for sure. I'm afraid you have just changed your Gods from your tradition to The Science Celebrities, you have too much faith in the world; you treat science as if it was religion !!! Because you're not thinking things out, you're following it just like another belief. You look for those in the world to belief then you let them think and decide for you what's right but you give it not one single thought of your own. It's a religion at that point, it not science. Here read this very, very carefully, maybe it can wake you up: http://answers.yahoo.com/question/index;_ylt=AgjYWT_J9VP4Er8YqT7lNkLty6IX;_ylv=3?qid=20120127073324AASPPm9

This is the difference between real and reality > being right and the truth! Humans beings have never been and will never be right, we are only ever truthful, relevant and coherent. Not real > but rather reality. Not right > but rather the truth. We conscious souls are fundamentally one and the same with different levels of spiritual awareness/awakening and mechanical differences. Materialism it's self is REALITY! The Torah revealed to moses around 3500 years ago teaches about The Ten Sefirot: Keter (Crown) which are described as angels of REALITY! Hinduism branched from the 4 Veda's written in Sanskrit around 3500 years ago teaches about Maya and Samsara, again REALITY! The decline of the Roman Empire led to the Spanish Inquisition > People deluded by heretics accusing people of being heretics, which lead to the worst torture of human beings imaginable. In 1209, Louis VIII of France through Pope Innocent III in Bezier raised Catholic forces and massacred 20,000 Gnostic’s who made every effort to follow the teachings of Jesus. They believed that there were two "gods" — one malevolent in charge of all visible and material things held responsible for all the atrocities in the Old Testament, and a benevolent god responsible for the message of Jesus. Remember we can place a computer and a human brain on a table > apply power to both > plug in the computer, place the brain into a human bio mechanical body/central nervous system linked to the cardiovascular system > Ok so both processors now have power > only one of them can tell it's self what to do > the reason for this is because one of them has mindful volition and free will due to presences of a conscious soul > God! According to Christianity satan was a First order Angel: Closest in order to God: "Seraphims" Keter - Crown Divine Plan/ Creator. (A powerful creator of reality) It obviously works through mankind to produce the catalytic seeds/realities which grow to concatenate in our own self destruction. George Georgeff once said "we ride the devils back providing he takes us where we want to go" 100 trillion atoms in one human cell 100 trillion cells in the human body You could say solar systems are atoms, and galaxies are cells. However interesting this is all conjecture, objective and subjective. Considering how many atoms make up the earth and in relative perspective to perceivable size, we could also speculate that galaxies are atoms trillions of which make up a cell, so there must be trillions os cells > trillions of universes.
