You're getting left behind.

By no means. I'm going with a different group.

This is the only picture that comes up under a search for Anuki that isn't ANIME RELATED

How is this relevant to the discussion?

i have found an interesting video about a diamond planet orbiting a pulsar,the site is in croatian but the vid is in english http://www.znanost.com/clanak/otkriv...icine-jupitera

i have also read about a star that has a temperature as a human body.

I also heard about that diamond planet, the Daily Mail explained that it was once a star but cooled down into a 100% diamond planet. I believe we had a debate earlier involving a purely hypothetical diamond dead sun, hypothetical because BM dismissed the idea as an impossibility. So...I suppose the scoreboard is BM:100 Irrationality:1

Bullet Magnet 08-28-2011 08:43 AM

We can check. That conversation was in this very thread. My conclusion was thus:
:

I think it much more likely that this planet would actually be a dead star.

A star like our own will fuse Helium into Carbon during its red giant phase, in the core where the pressure is sufficient (and clearly sufficient for diamond formation). The stellar evolution cycles I know for this size always go to white dwarf, I'm not sure where diamond star comes into it. I'd suggest a cooled white dwarf, ie a black dwarf, but I don't think the universe is old enough to yet contain any such objects. There's probably something else I don't know about. I recall also writing this:

Of course, I am fully prepared to be proved totally and utterly wrong by genuine discovery, as a good deal of astronomical assumptions and expectations have been (usually by probes).


STM 08-28-2011 08:52 AM

Oh well in that case it's BM: 101 Irrationality: 0

how long would a black hole with the mass of a reletively earth sized planet last assuming it doesn't consume very much matter

I believe your black hole has fallen at the first hurdle there.

That hurdle being 'Having enough matter to be a black hole'.

Nate 09-12-2011 04:09 AM

Second hurdle being the concept that black holes consume matter, thus depleting a limited resource and burn out.


EDIT: That's cruel. I'll explain.

Black holes can theoretically be any size, as long as the mass is compressed small enough. In practice, only stars that are above a certain size will ever have enough mass to compress down to black hole status. Once this has occured though, black holes don't 'feed' on matter. Anything caught within the gravitational pull that is unable to get away will be sucked in to it and added to its existing mass. The black hole will thus get bigger and its gravitational pull stronger.

If no mass is sucked in to the black hole in a very long time, it won't burn out, it will simply remain the same size with the same gravitational pull.

STM 09-12-2011 09:26 AM

Although it is now understood that a black hole does not suck in all matter but in fact some matter saps the strength of a black hole, that and Hawking's Radiation convey the plausibility of a period after the black hole era.

Nate 09-12-2011 05:55 PM

Some matter saps the strength of a black hole? What the heck are you on about?

Yes, I was aware of Hawking Radiation. I was giving the simple explanation, appropriate to LDG519's current level of understanding. I assumed that it would be sufficient, what with Hawking Radiation currently being an unobserved theory and all.

You know, Kryptonite.

i just saw some wierd things on an science site,they say that there is a star that shouldnt exist and its old as the universe is,and it still didnt go into red giant to white dwarf phase,also i read about some guys finding ancient batteries in egypt and a baghdad battery.wery wierd.

Nate 09-13-2011 03:23 AM

I think that you need to revisit the way you define 'science site'. People who claim such things are not really operating in the world of real science.

I will try and find you proof as soon as possible but I'm swamped right now and can't get the site/ video.

Scraby 09-13-2011 09:22 AM

no its actually a site where our scientists and informers give info and post it on the site,i know a guy from there who is a scientist...

'The Baghdad Battery' is actually understood to be likely some sort of electrical power device. Who knows?

Bullet Magnet 09-13-2011 11:35 AM

I should also mention that "I'm a scientist" doesn't count as a credential. "I'm a scientist and here is my evidence" does. "I'm a scientist and here is my evidence and this is actually my field of expertise" is even better.

STM 09-13-2011 11:42 AM

I'm a scientist. A got a B in Chemistry Exam 3. Nate I'm still trying to find that evidence btw.

Wings of Fire 09-13-2011 12:15 PM

I'm a scientist, I'm actually engaged in research overseen by a professional with heaps of credentials in an academic institution using cutting edge brain scanning techinques.

STM 09-13-2011 12:47 PM

You're a psychologist aren't you?

Bullet Magnet 09-13-2011 03:14 PM

Brain scanning is Neurology. Unless Joe is desperately trying to bridge the gulf.

Our university's Psychology department is very firmly on the 'Physiological' end of the discipline.

http://en.wikipedia.org/wiki/Baghdad...Non-electrical

'The Baghdad Battery' is actually understood to not be a battery, despite physical appearances, as it simply wouldn't have worked. Also, no uses of electricity have been found in the archeological record; the theories about it being used for electroplating are especially unlikely as no electroplated artifacts have ever been found from that era.

Occam's Razor woudl suggest that it's much more likely to be a storage vessel than a battery.



Also, for what it's worth, I'm a scientist working as a researcher and PhD student in a respected institution, who has been published and presented at an A-rated conference. But that doesn't mean you should respect my views on archaeology. The fact that I do a minute amount of research and question the plausibility of whatever pseudoscience is presented to me should be a better indication of my reliability.

isnt it a bit strange that all of these civilisations knew star systems that we dont have the idea that they exist,and also those airplane models found in the aztecs and the saquarra bird that is actually an airplane,time rottened the wood and most of its parts fell off...

What a convenient lack of evidence.

Nate I found your evidence for the black hole thingy:



This is what I meant, I can't find the exact time but I expect you'll enjoy listening to the whole thing any way. It's a very amazing and insightful video.
