To elder children and young adults, it is a bonanza since everything becomes transparent. The “ugly” dependency of the speed of light on the local pull of gravity – that it is slowed in the vicinity of the sun (Shapiro) and comes to a standstill at the horizon of a black hole (Oppenheiumer) – 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 “Big Bang” is no longer a physical reality. A new freedom – a vast new spatial reality to roam – opened itself up.

The same liberation has almost the opposite effect on slightly older young people – 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’s own work?

The latter job is a joy. A renaissance of the young Einstein – of the three years of his miraculous period ranging from 1905 until late 1907 – follows. These years were fueled by the universal constancy of the speed of light c in the vacuum as is well known.

What about the famous “Einstein equation” 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 “too short” spatial distances for the elongated light travelling times just get proportionally stretched. The “Shapiro time delay” is now accompanied by a space dilation (“Shapiro-Cook space dilation”) and the infinite temporal distance to the horizon of a black hole is accompanied by an equally infinite spatial distance valid from outside.

The oldest and most important solution to the Einstein equation – the Schwarzschild metric – 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 – author of the famous “Kerr metric” for a rotating black hole – may be willing to to accomplish the re-writing task for the Einstein equation which will then reveal a whole new physics.

Does the successful repair of a flaw that had gone undetected for a century (*) really need to be called a “catastrophe”? The opposite is the case. One sobering consequence also follows, however: When even the “hardest science” – physics – 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.
