Each force is mediated by a force carrying particle - photons, gluons, W & Z, Higgs and tha pesky graviton. The working assumption - the one that puts gravity in the Standard Model - is that the graviton is too massive to find with current accelerators. The fact that the Higgs came in so light - about 125GeV - give researchers at the LHC some hope...mikeyhttps://www.blogger.com/profile/13057701313718589322noreply@blogger.comtag:blogger.com,1999:blog-8526498499129692237.post-80752292685756814752017-09-20T22:36:04.658-04:002017-09-20T22:36:04.658-04:00At the event horizon of a black hole, the curvatur...<i>At the event horizon of a black hole, the curvature of space becomes infinite in 'a nasty way'. Crossing an event horizon, an observer would experience an 'oh, damn, what do I do now?' moment. </i><br /><br />I'm gonna have to beat you around the head and shoulders with a copy of 'Gravitation' for that. You're confusing "curvature" with "degree of tipping of the light-cones" -- there's nothing special about curvature at the event horizon. Things don't go higgledy-piggledy until the central singularity.Smut Clydehttps://www.blogger.com/profile/09409476490132867809noreply@blogger.comtag:blogger.com,1999:blog-8526498499129692237.post-4586747364808932372017-09-20T18:55:46.244-04:002017-09-20T18:55:46.244-04:00Thanks for catching that.

I don't know whether to blame the error on the fact that I was drunk when I took notes, or I was sober when I wrote the post.Big Bad Bald Bastardhttps://www.blogger.com/profile/01983025559556548658noreply@blogger.comtag:blogger.com,1999:blog-8526498499129692237.post-43209500294316657442017-09-20T06:24:18.692-04:002017-09-20T06:24:18.692-04:00a white dwarf is the remnants of a star approximat...<i>a white dwarf is the remnants of a star approximately the size of our sun compressed to a diameter of approximately a kilometer. </i><br /><br />Please review.
