Although the cause of the Universe/Multiverse is a mystery, our causal human ethical principles are of and are based upon the physical properties of this system. Namely time.
Time allows for causal events to occur; the effect of one thing causing the next thing to occur in time.
However, the strange thing which a physicist does when they model the universe, is that their variable or model of the universe in regards to time is non changing or static.
So, a physicist, may just draw a picture, a model, of the universe and say this is what the universe is and ever will be. The physicists mathematical models are the only thing which may describe the universe with all the time already experienced and ever will be experienced in the future, already in their model.
The universe appears static to a physicist. Despite time unfolding as it does to us mere mortals.
Program Description "The Fabric of the Cosmos," a four-hour series based on the book by renowned physicist and author Brian Greene, takes us to the frontiers of physics to see how scientists are piecing together the most complete picture yet of space, time, and the universe.
With each step, audiences will discover that just beneath the surface of our everyday experience lies a world we’d hardly recognize—a startling world far stranger and more wondrous than anyone expected.
String theory is an active research framework in particle physics that attempts to reconcile quantum mechanics and general relativity.
It is a contender for a theory of everything (TOE), a manner of describing the known fundamental forces and matter in a mathematically complete system.
The theory has yet to make novel experimental predictions at accessible energy scales, leading some scientists to claim that it cannot be considered a part of science.
String theory mainly posits that the electrons and quarks within an atom are not 0-dimensional objects, but rather 1-dimensional oscillating lines ("strings").
The earliest string model, the bosonic string, incorporated only bosons, although this view developed to the superstring theory, which posits that a connection (a "supersymmetry") exists between bosons and fermions.
String theories also require the existence of several extra, unobservable dimensions to the universe, in addition to the four known spacetime dimensions.
Level I: Beyond our cosmological horizon A generic prediction of chaotic inflation is an infinite ergodic universe, which, being infinite, must contain Hubble volumes realizing all initial conditions.
Accordingly, an infinite universe will contain an infinite number of Hubble volumes, all having the same physical laws and physical constants.
In regard to configurations such as the distribution of matter, almost all will differ from our Hubble volume.
However, because there are infinitely many, far beyond the cosmological horizon, there will eventually be Hubble volumes with similar, and even identical, configurations.
Tegmark estimates that an identical volume to ours should be about 1010115 meters away from us.
This estimate implies use of the cosmological principle, wherein one assumes our Hubble volume is not special or unique. By extension of the same reasoning, there would, in fact, be an infinite number of Hubble volumes identical to ours in the universe.
Level II: Universes with different physical constants
"Bubble universes": every disk is a bubble universe (Universe 1 to Universe 6 are different bubbles; they have physical constants that are different from our universe); our universe is just one of the bubbles.
In the chaotic inflation theory, a variant of the cosmic inflation theory, the multiverse as a whole is stretching and will continue doing so forever, but some regions of space stop stretching and form distinct bubbles, like gas pockets in a loaf of rising bread. Such bubbles are embryonic level I multiverses. Linde and Vanchurin calculated the number of these universes to be on the scale of 101010000000.
Different bubbles may experience different spontaneous symmetry breaking resulting in different properties such as different physical constants.
This level also includes John Archibald Wheeler's oscillatory universe theory and Lee Smolin's fecund universes theory.
The Bolshoi simulation is the most accurate cosmological simulation of the evolution of the large-scale structure of the universe yet made (“bolshoi” is the Russian word for “great” or “grand”).
The first two of a series of research papers describing Bolshoi and its implications have been accepted for publication in the Astrophysical Journal.
The first data release of Bolshoi outputs, including output from Bolshoi and also the BigBolshoi or MultiDark simulation of a volume 64 times bigger than Bolshoi, has just been made publicly available to the world’s astronomers and astrophysicists.
Additionally, the graviton (G), a hypothetical elementary particle not incorporated in the Standard Model, if it exists, must be a boson, and could conceivably be a gauge boson.
Standard Model The Standard Model falls short of being a complete theory of fundamental interactions because it does not incorporate the full theory of gravitation as described by general relativity, or predict the accelerating expansion of the universe (as possibly described by dark energy). The theory does not contain any viable dark matter particle that possesses all of the required properties deduced from observational cosmology. It also does not correctly account for neutrino oscillations (and their non-zero masses). Although the Standard Model is believed to be theoretically self-consistent, it has several apparently unnatural properties giving rise to puzzles like the strong CP problem and the hierarchy problem.
We're missing a Graviton particles which would explain gravity and would also complete the standard model.
terry my understanding of physics is that time is not static. it is possible in physics for time to flow either way. for example, an antiparticle formed in a virtual particle may be considered the regular particle moving backward in time. one moves forward, one moves backwareds and soon they recombine and return the energy borrowed from the scalar vacuum energy. further, thermodynamics acknowledges that entropy defines times arrow by always going from more order to less order. the dissapated perfume will never return to that bottle, even though it is possible, because of entropys arrow. arp a note: recent research in dark matter looking for a supersymetric neutralino may have to be completely rescaled. physicists relying too heavily on SUSY were looking at the wrong mass range. was reading about that in science news.
Yes. True. Time may go forward or backward or this or that.
Our natural perspective of the way the world is is that the universe is composed of up down, left right, forward back, and time.
This issue with our subjective experience of time moving forward only and perhaps our more accurate models which include time going either forward or backward means much of us are believing in something that is inconsistent to the way the world actually operates.
How do we come to agreement with each other when we are all pretty much walking talking inconsistencies with regard to someone else's model.
i agree. much of our perception is based on what we can see. the effects of relativity only occur at high velocities and in strong gravitational fields. are you suggesting that we are divided into two large groups: one group has a grasp of how the real world functions and another group lives in a pre-enlightenment world of feelings and purely local perceptions? arp
All of us have some sort of "philosophy of life," even though we may not have verbalized it. Here you can get ideas for your own philosophy of life. You can see what others think of your own philosophical ideas, and you can help others to become clearer in their own thinking.
When there is difference of opinion, we have an opportunity for "friendly debate," a very growth-promoting experience.
