According to cosmologists from cambridge university, the universe is currently made up of: 70% Dark energy 26% Dark amtter 3.5% Ordinary Nonluminous matter 0.495% Ordinary Visible Matter 0.005% Radiation What could be the reason for so much Dark energy and Dark matter? one would expect the universe to be made of things we can see.
I was starting a discussion dont quote me on it Please Register or Log in to view the hidden image! Im just amazed that the majority is anti matter, and anti particles. I was expecting to see a 50/50 split in matter and anti matter in the universe, since popular thought suggests that equal amounts were created in the big bang.
Maybe dark matter is potential matter........ Please Register or Log in to view the hidden image! Just a thought Please Register or Log in to view the hidden image! :m:
The number you gave make no mention of antimatter or anti particles, it mentions dark matter, but this is not the same thing; we can see antimatter.
It's perfectly simple old man. There's a special formula. 70% Dark energy + 26% Dark matter = there's a whole 4% of the Universe out there we can probably claim to actually know something about.
Hum, Indeed, there was almost a 50/50 creation of antimatter and matter in the early universe. And of course they cancelled each other out; but not exactly… There was a small (violations of <b>CPT</b> Invariance ) imbalance of about a billion to one, and we ended up with a billionth of the matter that was left. The symmetry was not exact; the nature of why that should be is still a mystery, that imho, involves the creation of space/time and the expansion of the universe..etc
My bad. Dark matter is not necessarily anti-matter. Dark matter is matter that for some reason doesn't emit or reflect light (at least not enough light for us to see). It could be purely transparent, never interacting with light. The gravitational field is there. Something is behaving as if it has mass. Still, for some reason we cannot see it. At a stellar distances, light is the only tool we have. Nobody really knows what dark matter is, but new theories are being developed on a regular basis. My theory was to consider it Anti Matter and make my life easier.
To rephrase what was stated by Mr Annonymous; there is 25 times as much out there as we are aware of!!! Since we had not the slightest clue, as to what and where it might be, we invented dark matter and dark energy to explain it. We must never say 'We don't know' We know it is there because our theories of gravity cannot be wrong!!! If there is that much can I suggest that some of it may be around here as well as out there. I have seen it suggested that the initial Michelson-Morley experiment was not as clear-cut as was soon assumed. I do however concede that it has since been done time and again, but do we always see what is truly there, or what we wish to see? There has got to be some fundamental flaw in our reasoning and I suspect it is in something we take for absolute granted.

Rather than just fess up and say - "Actually, we got bunkus" there prevails this interminable culture where in actually terribly intelligent people prattle on knowledgeably about what it is they don't, literally, actually know as if they do. If that was the all of it I'd applaud all the way, but its the tendency to contrive that its actually an achievement that really is taking the piddoodle...
