matahari ialah bebola gas atau cecair ?   (atau pepejal ?)

The Sun Liquid or Gaseous?
A Thermodynamic Analysis





siapa yg kuasai dunia , maka jawapan dia lah yg akan tentukan apa itu matahari.

ilmu boleh diubah2 ikut zaman , sebab tiada org tahu apa itu matahari .

org yg kawal dunia boleh reka apa yg mereka suka .

terus kpd Conclusion



Relative to the Sun, a condensed approach brings interestingcontrasts and dilemmas versus the gaseous models.
The latterare endowed with tremendous mathematical flexibility [1, 2],
but their physical relevance appears limited. Gases cannotby themselves impart structure and the solar spectrum is noteasily explained in a gaseous framework [9].
The gaseousstars suffer from the stellar opacity problem [9].
Conversely,a liquid metallic hydrogen model imparts a wonderful abilityto explain the origin of the solar spectrum relying on thelayered structure held in common with graphite [141–149].
Metallic hydrogen possesses a very high critical temperatureand can exist as condensed matter even on the solar surfaceaccounting for many features of the Sun best characterizedby material endowed with a lattice [141].
Most of the physicalattributes of the Sun are more simply explained within theframework of a liquid model [141]. However, a condensedSun is not as open to theoretical formulations.
The advantagesof a liquid Sun are now so numerous [20, 141–149] thatit is difficult to conceive why the model was not proposedlong ago.
This speaks to the allure of the gaseous Sun and themathematical beauty of the associated equations of state.In closing, it should be highlighted that there is currentlyan effort to describe the Sun as “liquid-like” (e.g. [162]).
Inthe end, the author believes that such terminology should beavoided. If the Sun is condensed, it should be viewed asliquid, not “liquid-like”. Even gases could be “liquid-like”.
Such terms cannot be sufficient, since a real lattice is requiredfor production of the solar thermal spectrum. No compromisecan be made on this point for those who have studied thermalemission in real materials.
“Liquid-like” might refer to anythingfrom a gas, to a plasma, to fully degenerate matter, tosupercritical fluid and none are necessarily endowed with alattice. The contention of this work remains that the photosphere of the Sun is liquid,
with true lattice structure andordered interatomic distances. The adoption of liquid metallichydrogen as a solar constituent brings with it a wealth ofpossibilities in describing solar structures and understandingthe solar spectrum.
Central to this advancement, the latticemust remain the foremost element in all of condensed matter,whether here on Earth, within the Sun, and even, in thefirmament of the stars.
