is it the pure heat of blackholes that causes light to bend

[mcgrobbles]

Could it be due to the heat caused by blackholes that gives the illuision that light bends, not the gravity ???<br />

Heat caused by the fusion of all incoming objects, perhaps heat can escape or maybe the heat is actually caused by the surrounding objects just before they are actually sucked into the blackhole,

No, it is definitely gravity of the blackholes that causes light to bend. <br /><br /> <div class="Discussion_UserSignature"> <font size="2" color="#14ea50"><strong><font size="1">We are born.  We live.  We experiment.  We rot.  We die.  and the whole process starts all over again!  Imagine That!</font><br /><br /><br /><img id="6e5c6b4c-0657-47dd-9476-1fbb47938264" style="width:176px;height:247px" src="http://sitelife.space.com/ver1.0/Content/images/store/14/4/6e5c6b4c-0657-47dd-9476-1fbb47938264.Large.jpg" alt="blog post photo" width="276" height="440" /><br /></strong></font> </div>

Are you certain that temperature cannot warp space-time; temperature affects: mass, length, and time?

You may be confused by the fact that hot air can cause optical illusions on Earth, most notably mirages (which are in fact bent light). But it's not the heat that's doing it. It's the fact that the heat is causing the air to move and affecting its density, which affects its optical properties, causing the air to bend light more than it normally does. (Air does bend light normally, which is why the moon is never completely dark even during the darkest of total lunar eclipses.) <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em>  -- The Tenth Doctor, "Blink"</font></p> </div>

No, radiated heat (as opposed to convected heat) through the vacuum of space from the sun, or a black hole, is in the form of infrared wavelength photons and outward bound protons or other particles created from the zero point field at the event horizon. As these particles are all emitted outward from the center of gravity, with outward force vectors, any interaction by them with passing photons from stars would cause those passing photons to bend OUTWARD, not inward. That light is in fact bent inward demonstrates that the gravity influence is actually much greater than the opposite emission-caused forces.

actually, radiated heat through space is not just IR photons, but any photons.<br /><br /> <div class="Discussion_UserSignature"> <p align="center"><font color="#c0c0c0"><br /></font></p><p align="center"><font color="#999999"><em><font size="1">--------</font></em></font><font color="#999999"><em><font size="1">--------</font></em></font><font color="#999999"><em><font size="1">----</font></em></font><font color="#666699">SaiphMOD@gmail.com </font><font color="#999999"><em><font size="1">-------------------</font></em></font></p><p><font color="#999999"><em><font size="1">"This is my Timey Wimey Detector.  Goes "bing" when there's stuff.  It also fries eggs at 30 paces, wether you want it to or not actually.  I've learned to stay away from hens: It's not pretty when they blow" -- </font></em></font><font size="1" color="#999999">The Tenth Doctor, "Blink"</font></p> </div>

correct the heat is caused by in falling material being so dense and having alot of kinetic energy (friction) to the point it emits electromagnetic radiation.<br />however light is bent by heat as the heat causes the medium in which the photons are travelling through to change density relative to the surrounding air, (like hot air of a mirage, or when you put your finger in the bath) in space however there is basically no medium which it is travelling thru so relative medium density is not a factor. (no refactive index) <br /><br />sorry CalliArcale<br />i didnt see your post until i'd done mine <br />glad to see someone paid attention in class ...heh heh<br />only kidding folks, if you dont ask you'll never know!
