Where's Ape? Feels like someone is missing at the family dinner table.
Once again, Einstein is hard to beat.
I don't see why you're making a laugh of that article. It's pretty clear. In fact it's so clear that I'm facepalming myself into the ground wondering why the researchers who did the experiment made this mistake in the first place. You can't measure a moving object from another moving object without compensating for the movement of the second object.

IDK, it sounded to me like a measurement problem. Didn't they have the same kind of measurement issue with GPS satellites?
No-one can deny that Einstein was a genius. Since Einstein the greatest minds on the planet have been studying his theories. There has never been anyone who could prove him wrong. Yet simultaneously all kinds of experiments lead to conclusions which supported Einstein's theories, even some when they weren't researching those at all.
All the young budding scientist with hot new theories like string theory would have been nowhere without Einstein's work. So even their work is based on his even if it is only from a will to prove him wrong. Now string theory is very interesting but it's also insanely difficult to comprehend. Who can say that theory is right or wrong? Or that Einstein's theory is right or wrong? Nobody can at this stage. They may even both be right. At this time there is a helluva lot more evidence to support Einstein's theories.
Regarding the Hawking radiation, I don't think that's far fetched at all. Black holes are mysterious things. Just because light can't escape them because of gravitational forces (which is in itself an assumption) doesn't mean there aren't other particles/waves that can. These things are supposedly sucking up massive amounts of matter/energy, it has to go somewhere.
Hawking Radiation In 1975 Hawking published a shocking result: if one takes quantum theory into account, it seems that black holes are not quite black! Instead, they should glow slightly with "Hawking radiation", consisting of photons, neutrinos, and to a lesser extent all sorts of massive particles. This has never been observed, since the only black holes we have evidence for are those with lots of hot gas falling into them, whose radiation would completely swamp this tiny effect. Indeed, if the mass of a black hole is M solar masses, Hawking predicted it should glow like a blackbody of temperature
6 × 10[SUP]-8[/SUP]/M kelvins,
so only for very small black holes would this radiation be significant. Still, the effect is theoretically very interesting, and folks working on understanding how quantum theory and gravity fit together have spent a lot of energy trying to understand it and its consequences. The most drastic consequence is that a black hole, left alone and unfed, should radiate away its mass, slowly at first but then faster and faster as it shrinks, finally dying in a blaze of glory like a hydrogen bomb. However, the total lifetime of a black hole of M solar masses works out to be
10[SUP]71[/SUP] M[SUP]3[/SUP] seconds
so don't wait around for a big one to give up the ghost. (People have looked for the death of small ones that could have formed in the big bang, but they haven't seen any.)
How does this work? Well, you'll find Hawking radiation explained this way in a lot of "pop-science" treatments:Virtual particle pairs are constantly being created near the horizon of the black hole, as they are everywhere. Normally, they are created as a particle-antiparticle pair and they quickly annihilate each other. But near the horizon of a black hole, it's possible for one to fall in before the annihilation can happen, in which case the other one escapes as Hawking radiation.In fact this argument also does not correspond in any clear way to the actual computation. Or at least I've never seen how the standard computation can be transmuted into one involving virtual particles sneaking over the horizon, and in the last talk I was at on this it was emphasized that nobody has ever worked out a "local" description of Hawking radiation in terms of stuff like this happening at the horizon. I'd gladly be corrected by any experts out there... Note: I wouldn't be surprised if this heuristic picture turned out to be accurate, but I don't see how you get that picture from the usual computation.
Back to the topic of this thread. The article gives clear reasoning about the error in the measurement. To me it doesn't read as if it was meant to put a feather up Einstein's butt at all. It reads as an admittance of failure on the part of the researchers. Of course if you read it wanting to find certain information than you shall find it.
I would say something more but I'll just say I question your scientific knowledge overmind, most of your propositions (which lack scientific and analytical bases) stem from a personal bias against Einstein, all the new 'young new theories' which you seem to support have concepts of constants in them. You're not looking at the actual concepts and the actual science, just the names attached to the theories/propositions.
You're throwing terms out there that require definitions, but to me, it seems like you're defining existence of something to be observable. So when you die, since you can no longer observe the universe, it must no longer exist using your reasoning which I'm pretty sure you're against. I think we had this discussion before...
When I die I hope you guys are still here arguing about this stuff.
