Perhaps a not so simple answer as the question may be... If one, by reasons we will ignore, was to build a empty sphere on the vacuum of space, lets ignore the composition of the sphere's walls, and subsequently one starts to heat up the interior of this very sphere to the limits, universe limits, this without ever melt of deform the sphere, what would become of the among of space fabric trapped inside of it? And what would be the reaction of the other space onto the presence of such object?obs.: Such sphere may not be able to to exist, if so, lets reduce the among of space on it's interior, and increase the quantity of matter, that forms the sphere's walls, simulating something like a celestial body, such as planet Earth, what then?
Would a light bulb produce ''heat'' in a vacuum?added - an astronaut experiences ''heat'' in space so how does the ''heat'' transfer from the Sun to the astronaut with no conduction or convection between the astronaut and the Sun?

A lot of bulbs have vacuum between the filament and the glass envelope.The heat is transferred by radiation, wavelengths in the infrared region.

Too heat the space up you would have to add a medium to the vacuum otherwise there would be nothing to absorb the ''energy'' and ''heat'' up (increase in temperature). However, I suppose if we were to ''flood'' the vacuum with electromagnetic radiation we may see some sort of change in the vacuum atmosphere. Would a light bulb produce ''heat'' in a vacuum?Or would there need to be an observer to ''feel'' the heat of the light bulb? Because the light would still be there.added - an astronaut experiences ''heat'' in space so how does the ''heat'' transfer from the Sun to the astronaut with no conduction or convection between the astronaut and the Sun?

This, "added - an astronaut experiences ''heat'' in space so how does the ''heat'' transfer from the Sun to the astronaut with no conduction or convection between the astronaut and the Sun?"Is sort of the whole question, but I'm not considering the common situation when solar winds, spectrum, travels trough space fabric, untill it hits the astrounaut, and this can feel it... I wondering exacly what cant naturaly happen outher, besides perhaps on the interior of a self fusion reactor as a sun, or inside a self contained dense atomic structure to conserve thermal... I still doubt that solar winds are spectrum being carried by space to the astronaut, and that the portion of space that was injected with spectrum adquire movement, and was ejected to the astronaut, not only the spectrum but the space on the surrownding areas, creating a different of density bewen the solar wind area and the normal space one, cold... For this considering that space when subjected to energy bends itself, no necessity of base, only energy as spectrum, and the act of be carring such energy is what is forcing space to achieve acceleration, in the case of winds, only in a straigt line trough the cosmos, being able to tranfer the energy as it goes further till it looses its acceleration at the edge of the heliosphere.... What I'm considering, and for this reasion speculating, is to do the same as your example, but instead of the space being adquiring acceleration due energy and spectrum, in a straig line away from the source, I consider to trap such field into a sphere like object, in specific a dense one, as a planets layers, both as for conservation of the effect, as for use its dense atomic structure as barrier to self contain the acceleration at the middle... I wondering, if I can make the straigth line irradiation that is inflating away from the heat source, hit against another high density wall that is as more energy or the same as the spectrum that is being carried, so there would be no short term transmision of such energy... I especulating if such condition would not promote a spinning acceleration that would increase its speed depending only on the energy of those walls, and those walls energy being related with the energy base of the object... Only trying to see if this wouldn't match to the relativity, only a change of the planets solid inner cores, to see if self contained space, that is constantly accelerating itself in function not of the mass of other planets or sun, but in function of the same event happening at the sun and other planets interior... This would lead to the mass as being as important as it iss not, but would diverge when gravity as being related as the gravitational pulls of the center of the planets one towards and away from the other, for this the mass would be only the catalisor, and never would have being two masses actracting one another, but the gravitationall interference one plante would have with the other... Resulting in a sun that is actually pushing the planets away, as the planets are constantly trying to join with the sun, and not the opposit... It's no big deal just a question, containing a lot of speculation, not as for myself, but as for being totaly compreended by others, those with the proper knoledge....
