The scale of the universe

I'd recommend going from smallest to largest.

I think this does that job better

The descriptions that we are given are still wrong. They just don't work.

Note to self: Go and learn quantum physics.

My theory is that we can go smaller as much as we can go bigger. The smallest currently being Einsteins quantum mesh, but quantum mesh doesn't just exist - it must be made up of something itself and those components made of something, and those of something etc etc. The fact that we can't see it yet doesn't mean it doesn't exist - it must exist. The big bang theory - a certain point anywhere in the universe doesn't just explode for no reason - there would have to be a chemical reason for it. And that leads us to the fact that the big bang may have happened 10,000,000,000 times before - we will never know. If we could get to the edge of the big bang that we know of, the very outer edge of space itself - what is there?? Ooooohhhh... we as humans do not or will not ever have the capacity to know unfortunately because it's very interesting..that's why i'm certain that there is no such thing as god....it's another way of saying 'fucked if i know - i'll just say there's a god' There's never been a god. Watch the above and tell me a god or religion makes sense...

There is a gif here showing a bit more

Not religious myself, but I think that the only thing that religion can hold onto is what caused the "big bang". If the universe started to expand after the explosion of a very dense, very hot conditions at the start, what caused that to begin?

It is "the" question that scientist have to answer, we will find out in our life time? Doubt it, but they are starting to understand with the new hadron collider.

The world is complex...or not -

**revolver** · #8 16-04-2010, 11:06 AM

Space is massive.

I have forgotten what the thread was about now, nice gifs.

**Burdock** · #10 16-04-2010, 08:01 PM

Humanity has always had great difficulty with the concept of some things being infinite... i.e having no beginning and no end.

That's space that is.

It makes my head hurt.

There are many realities. We can understand 3-dimensions in space (height, length, breadth) and, to a limited extent, time. This gives us 4 dimensions, our brains are incapable of understanding more.

Most theoretical physicists believe that there are many more dimensions than height, length, breadth and time. We can't describe them because we are not aware of them. We don't understand what happens at the quantum level although we observe things that goes against our ken. Things happen at the quantum level that shouldn't if we have just a length/breadth/height/time driven world.

To try to demonstrate what I'm waffling about, rather than trying to imagine one of the 'extra' dimensions, I'll ask you to try to forget about one of the dimensions that you know. Imagine that there is no 'height' in your understanding of the world. You would live on in length/breadth and time but would have no idea what was happening above or below you.

Somebody that was above or below you would have no idea of your existence as they would have no concept of height, if they were bound by the same rules.

Is anybody following what I'm talking about?

Yeah I get it. Like you say it's a much easier way of trying to understand something which doesn't (as we know it) exist.

Who was it said that the big bang theory has happened time and time again? My theory on that is that if there was a big bang which caused everything to push outwards at a phenomenol rate, then the matter pushed out (stars and galaxies n shit) would have to eventually slow down and then come to a stop, once this happens I believe that everything starts to come back on itself until eventually it's all forced back to the point in space and time it came from and eventually, when the pressure becomes too much, lo and behold, there's a huge explosion and it all starts again!

There is evidence that the universe is slowing down apparently. This begs the question that if my theory is correct, once everything does start to come back on itself, does time also go backwards? Do we just keep repeating ourselves over and over and over? Are we just some snot nosed kid's science class experiment living in a petrie dish in his bedroom on a plane we can't comprehend cos all we know is this universe he's created?

If we do just keep repeating time, then that certainly explains deja vu!

A point of interest (to me anyway), on that scale there's a bit that shows the size of the largest virus and a bit that shows the smallest particle a surgical mask can block out. According to this scale the largest virus can easily pass through a surgical mask. Does this mean surgical masks are useless?

**adam_ayres1988** · #14 15-04-2011, 11:48 AM

I suppose it would mean surgical masks wouldn't be too effective at preventing the spread of an airborne virus, but they're still useful for other things I'm sure.............even if it is just to scare the crap out of someone

as far as i know you cant get something out of nothing - i can't make bread without the ingredients and i cant make an alloy wheel without alloy so the very chemicals in the first reaction that started the big bang had to come from something already established which leads strongly to there already being something there beforehand.

What happens when a massive black hole 'turns inside out'?

It becomes a massive white hill obviously

My theory that we were created by a snot nosed kid living in a petrie dish in his bedroom on a plane we can't comprehend because all we know is this universe he created for us. Or God started it all off as a bit of a laugh?
