Hang on a minute! Are you all saying things are different from the middle of your universes? :) I think I need a lie down now... :)

*weakly - from chaise longue* but what if there was a lot of matter around the bit that went boom... when it went boom and expanded into what we can see... propelling or pushing everything else outwards so that we can't see it... yet... till it's light reaches us? :)

edit: I'm not sure that question made sense once it left my head...



Sure it makes sense Annie. About 300.000 yrs after the big bang, matter became visible and the 'soup' of protons, neutrons, electrons and other particles began to form shapes by attracting eachother and become celestial bodies. (hope that answers it a bit:(

[edit] I'm not sure but I think photons didn't exist before that time...

Lets get back to the basics, measurement of time. 60 seconds =1 minute, 60 minutes=1 hour, 24 hours=1 day, 365 days=1 year. All of this is base on one thing, movement. Movement by the means of the rotation of the Earth and the orbit of the Earth around our sun. In order to have movement you have to have the means to do so, Space. Take away Space and you take away the ability to have the concept of time. As I said earlier the farther point A is from point B the more time you create, subtract the Space, the less time you have. Julie brought up the issue of half-steps, I agree, you can never eliminate Space. A good reference of this is the movie “The incredible Shrinking Man” or the PBS series on String Theory. So do boil this down a bit I would say, no movement, no time, no Space, no time and as I think, once you are in Space our concept of time no longer applies anyway.

Now some of you are talking about the Big Bang, the Expansion of the Universe and the speed of light, these are some of my thoughts on this. We have discover that there is something out there other then Space and I think they called it Dark Matter. Supposedly it’s the glue that holds every together. So I think that before the Big Bang this is what there was, 100% Dark Matter, then BANG! The universe is form. But it is expanding and in order to expand you must some something to expand in, since it can’t be Space it must be the Dark Matter. You hear a lot of people ask the question, what is at the end of the Universe? My theory, it is 100% Dark Matter.

Keep these posts coming, love to read them AND get educated.

The kicker is the black hole or singularity must have been around for google's of years to get enough mass before the big bang. We have yet to see a black hole explode in our time but it has been said they do. It would make a bad day near by.

I'm disappointed, I ask a very simple question and get, well I don't know what I got. This forum is much better at political discussion than science.

We get links and flirting. Simple math, addition, shows at some point matter went faster than the speed of light. YES or NO?

Oh, sorry, I thought someone had already answered that. Yes - due to expansion I think was what was said, but I'll go back and have a look...

Have a look here perhaps: http://setiathome.berkeley.edu/forum_thread.php?id=74455&postid=1516721

... I was not flirting... :) I was recovering from a shock...

Another edit: yep - a lot of people have answered the question I think... I didn't though :)

Simple math, you can find anywhere, friends is a different matter:)

NO.

I thought I explained that matter did not go faster than the speed of light. I don't think you have me filtered, but I will explain again.

The space-time continuum is expanding faster than the speed of light, the spaces between objects is getting larger. Much like if draw two dots on a balloon then as you inflate the balloon the dots will get further apart.

You keep asking for simple maths, but this is not governed by simple maths.

This is the sort of maths you need Metric Tensor to understand the theory of general relativity (how space-time curves).

Hmmm... and as we don't know a lot about dark energy and dark matter... who is to say the idea doesn't have merit? Thank you David! It's got me thinking...

Flirt? you must be kidding, you ask a question we gave an answer flirting had nothing to do with it. you might try another spot if that's what your looking for but not here. These are good freinds and we chat the best we can. Flirting is out so don't give me that. stick to the questions other wise move on.

That's another shortcoming this board has; quotes don't list the handle of the person being quoted. It wasn't you. Of course as your handle is not in the quote who knows.

Concentrate on the benefits, not the shortcomings, and this isn't science so it's off topic.

Not quite, what they have called dark matter is in space and part of it, apparently.

But it is expanding and in order to expand you must some something to expand in, since it can’t be Space it must be the Dark Matter. You hear a lot of people ask the question, what is at the end of the Universe? My theory, it is 100% Dark Matter.

Our observable universe must be expanding into something, that is logical, but not necessarily dark matter. Grant and I have a bubble universe theory that could answer your questions.



I know that there is Dark Matter in what we consider Outer Space, but I think that there is a possibly that this matter somehow got mixed in what we call our Outer Space due to the expansion of the Universe. I’m just guessing this for I do not have the slightest idea on how it really works. Like I said, not in the slightest way am I a scientist, heck of a video artist, Space just grooves me. Have to look into that bubble theory.
