Post Big-Bang 'Weirdness' --Radical New Theory Says the Early Universe Had Only 1 Dimension (and That a 4th Exists Today)

Scientists have outlined a test to discover if the early universe had just one spatial dimension. This mind-boggling concept is at the heart of a theory that University at Buffalo physicist Dejan Stojkovic

Wouldn't that be some thing?!?!?!

This is very interesting, and does make sense at an intuitive level. Thanks, Nancy.

I don't believe in the one dimension and I don't believe in the big band theory.

I guess I sort of agree and disagree. I always consider Time as the second dimension that is inseparable from any First dimension. Anything that exists does so in the process of change, or motion if you are a purist that insists that time is a totally man made construct for dealing with motion/change, and that requires consideration of time a dimension. So as normally discussed there are always at least two dimensions and that means we live in a 4. 5, 6 dimensional reality already. And then that brings me to my pet peeve, that I always argued with my high school physics teacher about. Why is every discussion of physics based on Euclidean, straight line, geometry when we know for a fact that it is only applicable over small sections of the real world! You can only use Euclidean geometry to build a bridge so long as the span is short enough not to include the curvature of the earth to a significant degree. It becomes more and more necessary to use Non-Euclidean geometric constructs when one creates any trajectory or construct in the Einsteinian universe where every object creates curvature in space, and every light wave/particle travels space that is curved again and again and again by objects. And Non-Euclidean lines are three dimensional because they are curves existing in time, so two NE lines always A)in Hyperbolic NEG move further away into infinity from each other from their common perpendicular( imagine a giant open ended ellipse apex sitting on a mirror) or B) in Elliptic NEG intersect twice at equal distances from their common perpendicular and then move away from each other(place the same open ended ellipse on the mirror only with the apex up) or you can try drawing the same euclidean straight sided figure once on the inside bottom of a bowl and once on the outside of a ball. Yes, I know, blah, blah, blah but it is one of 'those things that just never stop bugging you' for me.

I love science; it is the bane of dominion religions that suppress thinking.

Way cooler physics than my school years, that's for sure~

Have you read "The Elegant Universe", a new book is out currently, another wonderful written epic of the blessed reader reading with "mouth wide open", incredibly exciting and relatively easy to comprehend...absolutely captivating and tremendously inspiring (for news of the world today".

Nuts I hit the wrong button'.

To finish my post:

Makes perfect sense.

You've got to love physicists. They are in a different world away from the norm and their language is totally obtuse from the ordinary. You've got to say, who knows? They just may be right!

Some physicists propose there are up to 10 or 11 dimensions. "Imagining the 10th dimension" video starts here:

Thank you Nancy. That's quite a lot to ponder. Be Blessed.

So mind-bogglingly interesting! How I love it when someone comes up with a revolutionary idea like this! it seems that the more we learn, the more we don't really know! It is so essential not to get too dogmatic about a theory, as often they are blown apart! I don't know about you, but I keep an open mind about every new idea that comes along. Thanks Nancy for this article.

As fascinating as this theory is, I was even more fascinated with the Laser Interferometer Space Antenna (LISA),
their eventual means of proving or disproving it.

Some information about LISA from NASA's website @ http://lisa.jpl.nasa.gov/
-------------
Gravity is talking. LISA will listen.

The Cosmos sings with many strong gravitational voices, causing ripples in the fabric of space and time that carry the message of tremendous astronomical events: the rapid dances of closely orbiting stellar remnants, the mergers of massive black holes millions of times heavier than the Sun, the aftermath of the Big Bang. These ripples are the gravitational waves predicted by Albert Einstein's 1915 general relativity; nearly one century later, it is now possible to detect them. Gravitational waves will give us an entirely new way to observe and understand the Universe, enhancing and complementing the insights of conventional astronomy.

LISA, the Laser Interferometer Space Antenna, is a joint NASA–ESA mission to observe astrophysical and cosmological sources of gravitational waves of low frequencies (0.03 mHz to 0.1 Hz, corresponding to oscillation periods of about 10 hours to 10 seconds). This frequency band contains the emission from massive black-hole binaries that form after galactic mergers; the song of compact stellar remnants as they slowly spiral to their final fate in the black holes at the centers of galaxies; the chorus of millions of compact binaries in our own Galaxy; and possibly the faint whispers of waves generated shortly after the Big Bang.

LISA consists of three identical spacecraft flying in a triangular constellation, with equal arms of 5 million kilometers each. As gravitational waves from distant sources reach LISA, they warp space-time, stretching and compressing the triangle. Thus, by precisely monitoring the separation between the spacecraft, we can measure the waves; and by studying the shape and timing of the waves we can learn about the nature and evolution of the systems that emitted them.

Thanks for the post, Nancy!

Oh wow, the more evidence and data we gather, regardless of which theory it is to prove, the more convinced I am that life on this planet is one giant cataclysmic accident of universal proportions...
Knoweldge is power and we have to keep delving into the unknown!
To be spoond fed is to exist and then die... we have to question everything.

interesting, Noted...
Thank you
