Intriguing New Equations Show a "Phased" Creation Our own universe does not seem to have come into existence this way. The phasetransition model is not meant to replace the theory of the Big Bang. “Today, cosmologists know a lot about the early universe – we are not challenging their findings. But we are interested in the question, which phase transitions are possible for time and space and how the mathematical structure of spacetime can be described” Astronomers combine mathematical models with observations to develop workable theories of how the Universe came to be. The mathematical underpinnings of the Big Bang theory include Albert Einstein's general theory of relativity along with standard theories of fundamental particles. Today NASA spacecraft such as the Hubble Space Telescope and the Spitzer Space Telescope continue Edwin Hubble's work of measuring the expansion of the Universe. One of the goals has long been to decide whether the Universe will expand forever, or whether it will someday stop, turn around, and collapse in a "Big Crunch?" ____________ rOZZ

The three main theories about the Universe are/were
2. The Pulsating universe that will collapse one day and, then expand again, then collapse ..... 3. The Steady State theory that is now obsolete The Big Bang is the current popular theory based on observations that show that everything we see is moving away from us at an increasing rate, which seems to suggest that at some time in the past there was some sort of massive explosion that flung matter everywhere from a central point. However it is not clear what caused the bang, and what it is expanding into. There are many theories on the origin of the universe and Julies one is yet another for the list.

It's been my little pet theory for some time now but it's just as good as some others I reckon:) We think we know what black holes are in that due to immense gravity, matter gets drawn in including planets and smaller stars, and even light cannot escape, hence the term "black". Wormholes or Einstein–Rosen bridges, are hypothetical features of spacetime that would be fundamentally a "shortcut" through spacetime.

As technology has evolved, astronomers are able to look back in time to the moments just after the Big Bang. This might seem to imply that the entire universe lies within our view. But the size of the universe depends on a number of things, including its shape and expansion. Just how big is the universe? The truth is, scientists can't put a number on it.

I read some time ago that scientists have used the WMAP data to essentially draw triangles as big as possible. They then measure the angles of the triangles to see if they add up to 180 degrees or not. Triangles with angles measuring 180 degrees are flat and therefore the universe is infinite. If not then the universe will be curved. So far the triangles measured are within 3 decimal places of 180 degrees so they said the universe is infinite. Cannot find the original article, sorry.

This article could shed some light on the matter.

Very interesting book by WunYi Shu, Institute of Statistics, National Tsing Hua University

Those formulas are just too much for me...

Those formulas are just too much for me... You have to start with the easy stuff like e^{i \pi} + 1 = 0

Those formulas are just too much for me... Euler's identity... [edit]Makes me think of the gelijkheids formule in Dutch, couldn't quite find the English equivalent. I guess you could call it the equality formula. [edit2]darn maths!!!! ____________ rOZZ

The Big Bang did happen. There is proof. Arno Penzias and Robert Wilson

I used to ride my bicyle past that antenna at lunch when I worked for Bell Labs. It really isn't that bigmaybe 12 feet high or so. Made out of what just looked like galvanized sheet metal.

The universe can simply be thought of as a giant globe that is infinite in size in all directions. All this stuff about curved planes and warping space time is just scientists trying to explain what they don't understand, and formulas that don't work unless they have the missing item X.

Thanx Chris:) (gelijkheid van Parseval...) ____________ rOZZ

Why not a cube instead? Because the distance from us that we can see is constant in each direction, If it was a cube it would be further to the corners than the sides. Cubism went out with Picasso 100 years ago.

Earthlings may be extreme latecomers to a universe full of life, with alien microbes possibly teeming on exoplanets beginning just 15 million years after the Big Bang, new research suggests.

Thanx Lynn:)
