To elder children and young adults, it is a bonanza since everything becomes transparent. The \u201cugly\u201d dependency of the speed of light on the local pull of gravity \u2013 that it is slowed in the vicinity of the sun (Shapiro) and comes to a standstill at the horizon of a black hole (Oppenheiumer) \u2013 is gone since the distances travelled are proportionally enlarged. Simultaneously, the so far assumed to be added-on expansion speed of the universe ceases to be an option so that the \u201cBig Bang\u201d is no longer a physical reality. A new freedom \u2013 a vast new spatial reality to roam \u2013 opened itself up.<\/p>\n
The same liberation has almost the opposite effect on slightly older young people \u2013 those who have to pass an exam or defend a thesis in a physical discipline. They are at a loss as to what still to believe and defend. Most textbooks have become obsolete. How discuss the new situation with Stephen Hawking, for example, or with CERN? Most importantly: How reconcile it with Einstein\u2019s own work?<\/p>\n
The latter job is a joy. A renaissance of the young Einstein \u2013 of the three years of his miraculous period ranging from 1905 until late 1907 \u2013 follows. These years were fueled by the universal constancy of the speed of light c<\/em> in the vacuum as is well known.<\/p>\n What about the famous \u201cEinstein equation\u201d of late 1915, however: Has it become obsolete since its c is not a global but only a local constant? The equation only needs a re-scaling. The \u201ctoo short\u201d spatial distances for the elongated light travelling times just get proportionally stretched. The \u201cShapiro time delay\u201d is now accompanied by a space dilation (\u201cShapiro-Cook space dilation\u201d) and the infinite temporal distance to the horizon of a black hole is accompanied by an equally infinite spatial distance valid from outside.<\/p>\n The oldest and most important solution to the Einstein equation \u2013 the Schwarzschild metric \u2013 exists already in a correct stretched-out version. Only the full Einstein equation itself still waits to be written down explicitly in the correct form by a daring newcomer. Alternatively, Roy Kerr \u2013 author of the famous \u201cKerr metric\u201d for a rotating black hole \u2013 may be willing to to accomplish the re-writing task for the Einstein equation which will then reveal a whole new physics.<\/p>\n Does the successful repair of a flaw that had gone undetected for a century (\u2022<\/span> really need to be called a \u201ccatastrophe\u201d? The opposite is the case. One sobering consequence also follows, however: When even the \u201chardest science\u201d \u2013 physics \u2013 could go awry for a whole century, a new humility is called for in physics. The strongest young generation of history is now at the ready aided by the no longer distant young Einstein.<\/p>\n Acknowledgment: I thank the three Universities of the Normandy for the undeserved honor bestowed in Le Havre on my chaos work done in the footsteps of Jim Yorke who, together with Celso Grebogi and Ron Chen, was most deservedly honored there.
