Religion and science both need a degree of faith, because once you leave the realms of Newtonen physics and try to learn Quatum theory, etc, more and more one is presented with it must be so if we are to explain the universe. Yet to explain the Big Bang we have to say that the now rules governing physics could not have existed until a good few nano seconds after.
We still havent looked at dark matte AND I dont mean Stout ale.

It was actually during a few drinks, and strange as it
may sound, a large number of students work through
the summer in Canada, and this was a farewell do
it was a subject being discussed along with Einstiens whats it.Some had left, and some sleeping
being absolutely ignorantly in the dark i kept stum
but i must have made one of my silly quips, as i
do on here,from time to time. It a million to one
occurance impressed him, so that was when
Tony,for such was he called went on to explain
how the shape of the universe fit into their thinking
and it should theoretically be possible to travell
in hours, what was then thought would normally
have taken months or years.
Of course science and its instruments have moved
on since then, but whose to say they were on the
wrong lines. Volkeswagon aint done so badly.

I read a really good book recently called "The Universe in a Nutshell" by Stephen Hawking.

If anyone (non-scientists like me especially) wants to try to understand the latest thinking on the universe then I can really recommend this book.

So we are nade of stuff that is and isn't, any second now we will begin to discuss the idea that the Universe is an entity that whilst constantly expanding only has dimensions within it self . (now I begin to understand Dr Who)

Yes Mick *nods head wisely*

But my explanation doesn't need a dictionary..................and makes far more sense:)


So there!! LOL

String theory is a still-developing mathematical approach to theoretical physics, whose original building blocks are one-dimensional extended objects called strings. Unlike the point particles in quantum field theories like the standard model of particle physics, strings interact in a way that is almost uniquely specified by mathematical self-consistency, forming an apparently valid quantum theory of gravity.

Since its birth as the dual resonance model which described the strongly interacting hadrons as strings, the term string theory has changed to include any of a group of related superstring theories and larger frameworks such as M-theory, which unite them. One shared property of all these theories is the holographic principle.

String theorists have not yet completely described these theories, nor have they determined if or how these theories relate to the physical Universe.[1] The logical coherence of the approach, however, and the fact that string theory can include all older theories of physics, have led many physicists to believe that such a connection is possible. In particular, string theory is the first candidate for the theory of everything, a way to describe all the known natural forces (gravitational, electromagnetic, weak and strong) and matter (quarks and leptons) in a mathematically complete system. On the other hand, many detractors criticise string theory because it has not yet provided experimentally testable predictions.

Like any other quantum theory of gravity, it is widely believed that testing the theory experimentally would be prohibitively expensive, requiring feats of engineering on a solar-system scale. Although some critics claim string theory is falsifiable in principle, they maintain that it is unfalsifiable for the foreseeable future, and so should not be called science.

String theory is of interest to many physicists because of the mathematics involved, and because of the large number of forms that the theories can take. String theory strongly suggests that spacetime has eleven dimensions,[2] as opposed to the usual three space and one time, but the theory can easily describe universes with four observable spacetime dimensions as well.[3]

String theories include objects more general than strings, called branes. These are black-holes charged with a differential form vector potential which has more than one index, a different type of electricity and magnetism where the fundamental objects are extended. By studying certain p-branes and identifying them with D-branes, endpoints for strings, certain types of string theory are shown to be equivalent to certain types of more traditional gauge theory. Research on this equivalence has led to new insights on quantum chromodynamics, the fundamental theory of the strong nuclear force.

wormhole


A hypothetical "tunnel" connecting two different points in spacetime in such a way that a trip through the wormhole could take much less time than a journey between the same starting and ending points in normal space. The ends of a wormhole could, in theory, be intra-universe (i.e. both exist in the same universe) or inter-universe (exist in different universes, and thus serve as a connecting passage between the two).

Wormholes arise as solutions to the equations of Einstein's general theory of relativity. In fact, they crop up so readily in this context that some theorists are encouraged to think that real counterparts may eventually be found or fabricated and, perhaps, used for high-speed space travel and/or time travel. However, a known property of wormholes is that they are highly unstable and would probably collapse instantly if even the tiniest amount of matter, such as a single photon, attempted to pass through them. A possible way around this problem is the use of exotic matter to prevent the wormhole from pinching off.

Kitty - you said that as a joke,
but it's truer than you think!

I think it's where spaceworms live.................I've seen wormholes in the sand at the beach, but never ever have I seen a spaceworm.

*goes to buy a telescope* :)))

Mick...............the string is up there to stop the stars falling down!!

*he knows nothing!!* LOL

Thanks to Mick I now finally understand what a Black Hole is.........now I have another thing to worry about......what the heck is a Worm Hole!!! ;-))))))

Mary

Ahh no! Dont start me on wormholes and string theory!

Now I know what a worm hole is. but do worry about where the spaceworms live! :)))

Light is affected by gravity Black holes drag light into them, bit like goverment tax officers, but it seems that they slowly emit a vapour of strings.bit like tax rebates never as much as you paid in
I wonder what takes if more belief in science helps but unlike Disney film you cant fall into a Black hole with out being torn into bits even electrons are destroyed. or so they say.
then there are worm holes. and other angels in heaven. Off to Grimstad next town down down from Arendal to get something for she who must be obeyed

Thank you Mick..................*tries to look halfway intelligent*

I get the second part, but the bit about light...............do you mean light, instead of bouncing back, kind of falls into the black hole?

I've confused myself now!?!?! lol

A black hole is a region of space in which the gravitational field is so powerful that nothing, not even light, can escape its pull after having fallen past its event horizon. The term "Black Hole" comes from the fact that, at a certain point, even electromagnetic radiation (e.g. visible light) is unable to break away from the attraction of these massive objects. This renders the hole's interior invisible or, rather, black like the appearance of space itself.

Despite its interior being invisible, a black hole may reveal its presence through an interaction with matter that lies in orbit outside its event horizon. For example, a black hole may be perceived by tracking the movement of a group of stars that orbit its center. Alternatively, one may observe gas (from a nearby star, for instance) that has been drawn into the black hole. The gas spirals inward, heating up to very high temperatures and emitting large amounts of radiation that can be detected from earthbound and earth-orbiting telescopes. Such observations have resulted in the general scientific consensus that—barring a breakdown in our understanding of nature—black holes do exist in our universe

Now you've lost me Mick.................I don't understand black holes at all!

Well I have suspected the GR invasion for quite some time :))))))))) LOL

Ahh yes Kitty, they are out there alright!

(and even a few on GR!)

So after a few drinks, a scientist told you that aliens travel by dimensions and the RAF had destroyed those dimensions.....................have I got that right?

If so, are we safe from alien invasion?

I have absolutely no idea if there is life elsewhere in the universe, but have a sneaky suspicion there might be.

Another theory is that the Tungaska "object"
was a small black hole.

(I do read a lot of science fiction).

Ah well 2 points hear, one i didnt get things mixed
up, ime naturally mixed up in my thinking.I was
trying to say, whilst watching that programme on siberas great what ever , they spoke of nassa is
it , firing a explosive rocket into what ever in space
and my point was, how did they know it couldnt
have gone haywire.
As for Aliens, they travell by using dimensions
now this german scientist,who worked with
von braun, i bunked with him in Canada and he
explained to me as best he could,me a sweede
bashing peasant, how they concluded there
was 7 dimensions at least, it went up in smoke
when the R A F bombed.But i shall not try to
explain what i remember of it, it being beyond
my limited intelligence, but it is firmly fixed in
my peanut.It came about as we all got pie eyed
and he swore me to secrecy, and i never did
give him away, a mans word is his honour and
if you dont have honour, you have nothing.
But he had a brain like a computer, could work
out all sorts of figures in his head, in no time.
And i had a strange, yet , unexplainable
experience myself some few months ago
and it made me think of the afore.
