What's the Fabric of space made out of?

Love it

Hey Buz, meet V-Bird.Hey V-Bird, meet Buz.[CD quietly retreats to the phreas]

Great advice - but I would caution you not to open yourself up to humiliation. To become educated, you need to express a willingness to learn. Shouting off rash opinions in a subject as complex as space-time physics will not gain you many potential educators. Ask questions. Lots of questions. And listen to the answers. Don't try and argue the subject - you don't know anywhere near enough yet to argue. If you don't understand, or if it sounds wrong, ask more questions. If your 'educator' is any good, he will keep explaining and explaining (time permitting) and you will start to learn.I would have suffered a great deal less humiliation if I had followed the above advice on my own journey to becoming a cosmologist

So what is energy? Are you sure? And the nucleus is made up of what? Please explain the Casimir Effect to me.

Hi Fabric - please don't listen to anything V-Bird says - he's a typical internet crank who thinks his ideas will replace the last 100 years of space-time physics. There's a million of his type out there, and they don't have a clue between them "Things" aren't made out of "energy" in any way.Smooth or discrete? Wow, that's a deep question. I would say eventually discrete, but whether there is still any semblance of what we would call space at the level it becomes discrete, I'm not so sure. I gues what that means is that as you look deeper and deeper, it would stop looking like space long before it starts looking discrete. But that's just a Sunday afternoon hunch Dark energy is a piece of cake compared to the above question. We're not sure what dark energy is in the same way that we're not sure what makes up the secert ingrediants in Coke or Pepsi. Is not that we have no clue... we have many clues, and we know many things that it definitely is not. But we're just not sure which guess is the right one yet. Don't let the popular press overstate our ignorance...Don't forget to use the reply button for adding posts - don't just use the general reply button (unless it is a general reply) as it breaks the flow.Edited by cavediver, : No reason given.

I asked 'what is energy?' - is that all you can come up with as a reply? It's a bit self-referential, don't you think? You seem to use 'energy' as a place-holder for your ignorance. That's not very scientific. Then how do I manage to calculate from theory the observed force to such high precision if I am wrong? Lucky guess???

No, it's not Yes, I do No, it's not. Why would I use virtual particles to explain the Casimir Effect??? I'm not some pop-science writer - I actually know what I'm talking about You seem to be wrong on quite a few counts here...

So an isolated non-rotating black hole has no energy? Really? You're not wrong *YOUR* reality, of course No, you bullshit, and I call it

What matter? I'm only considering bosonic fields. There is no motion. Is there no energy? I'm sorry, is this English? Ah, apparently English is taking a nap today... I have shown you the 'vice versa'. Sadly, you seem to be about ten years of study away from being able to understand my example.[ABE]Sorry, just had to comment on this: I'm sorry, your technical black-hole jargon is way over my head Edited by cavediver, : No reason given.

He's got a point, Percy. As far as I am aware, Hawkins does indeed understand the consequences of the red dobbler.[help, I think I'm dying...]
