Imaginary interview with Alfred Wegener

Winter 1929, University of Graz. In an office cluttered with world maps pinned to the walls and leather-bound notebooks, a man with clear eyes, already marked by polar winds, prepares a new expedition. Alfred Wegener agrees to look back on three decades spent defending an idea his peers consider insane.
—How did you first get the intuition that the continents might have been joined?
It all started with something almost embarrassingly simple: a geographic map spread out on my table. Tracing my finger along the coast of Brazil and that of the Gulf of Guinea, I saw what every schoolchild sees but dares not say — that they fit together like two pieces of the same torn sheet. I was told it was a coincidence. But a coincidence does not deposit the same fern fossils on both sides of an ocean thousands of kilometers wide. I turned my globe over for entire nights, and each time I came back to this conviction: these landmasses once formed a single block, which I named Pangaea, and a slow drift has separated them.

—What does your 1912 work, where you present this theory, mean to you?
In Die Entstehung der Kontinente und Ozeane, I wanted to bring together what no geologist would agree to look at together. I wrote that the coasts of South Africa and South America fit together like puzzle pieces, and that such a correspondence cannot be mere chance. My profession as a meteorologist had taught me one thing: you only understand the atmosphere by cross-referencing measurements from opposite ends. I did the same with the solid Earth — combining geology, paleontology, climatology. Each alone remains a fragile clue; all together, they form a convergence of evidence pointing to a single conclusion.
—Why did your colleagues receive this evidence with such hostility?
Because I lacked the essential: the engine. My opponents readily conceded the identical fossils, the interlocking shorelines, but they always asked the same question — what force, in the sky or beneath our feet, could push such colossal masses to travel? I had no satisfactory answer, and a scientist without a mechanism is, in their eyes, a dreamer. In 1922, the rejection became international. One of them declared my theory as impossible as a hippopotamus floating in the clouds. You cannot discuss an idea you have already decided to ridicule.

—How does it feel to be mocked by an entire community?
I would lie if I said it slides off me. At a congress in 1926, I heard men I respected dismantle my arguments one by one, not through calculation, but through indignation. There is a particular solitude in holding an idea you know is right but cannot yet fully prove. But I learned patience under other latitudes: when you have spent weeks stuck by a storm on the Greenland ice cap, you understand that nature yields neither to shouts nor to votes of academies. I continue to gather my evidence, line after line, and I let time do its work as arbiter.
—What exactly are you seeking in these Greenland expeditions?
Numbers. Greenland is the greatest open-air laboratory I know, and it does not lie. As early as 1906, I went there with my barometer and thermometer, to probe an atmosphere that no one had measured at those ice heights. My field notebook fills with readings that I later bring back to Marburg, then here to Graz. These data nourish my understanding of ancient climate as much as my theory of drift: for the climate of the past, etched in rocks, tells where the continents were when they bore glaciers where deserts now stretch.
—Did you never consider the danger of these icy crossings?
One never forgets the cold of Greenland; it inhabits you long after returning. Each expedition is a tight calculation between provisions, dogs, and distance to the interior station. I have seen strong men yield to the blizzard, and I know that ice does not forgive recklessness. Yet I go back, because the measurements that matter are not taken from a Viennese armchair. If I were to lose my skin there, I would rather it be in accumulating honest observations than in polishing theories by the fireside. The field has its demands, and I have accepted them once and for all.

—You are presented as a geophysicist, but your first science was different. Which one?
Meteorology, without hesitation. Before the continents, I studied air, currents, the march of storms — my early works, between 1905 and later, focus on the physics of the atmosphere. It is this training that gave me a taste for mobile, unstable, ever-moving phenomena. When I looked at the solid Earth, I did not see a fixed foundation like my geology masters, but something that, on a scale of millions of years, flows and rearranges like an air mass. My father-in-law Köppen, a climatologist, immediately grasped the link: the climate of the past and the position of the continents are two pages of the same book.
—What role does your correspondence with Wladimir Köppen play in your approach?
A huge role. In our letters, exchanged between 1911 and 1915, I confided that I had gathered geological, paleontological, and climatological evidence all converging toward the same original supercontinent. Köppen, a man of climate, helped me link the heat and ice belts of the past to the drifts I was postulating. Our Research on Historical Climatology was born from this dialogue: reconstructing ancient climates to guess where the continents lay before their separation. It is not a lone man who builds a theory; it is a patient, sometimes contradictory conversation, where each brings the piece the other did not see.
—If you were read a century from now, what would you want to be remembered?
I cannot promise that, for the future belongs to no scientist. But if I allow myself to dream that I am still read in a hundred years, I hope that what will be remembered is not the ridicule of the flying hippopotamus, but the method: cross disciplines, make rock, fossil, and climate speak together. Perhaps one day the mechanism I lack will be found, and then my continental drift will cease to be a heresy and become an evident truth taught to children. I will likely not have the joy of learning that. A right idea can slumber long before people consent to hear it.
—What would you say to those who judge your theory already condemned?
That they mistake the silence of a science for its last word. The geology of my time believes the continents are immobile, fixed once and for all; I believe they drift on the surface of a crust less rigid than imagined. One of us is wrong, and only time, armed with instruments we do not yet have, will decide. I have seen too many certainties collapse — Bohr reshaped the atom in my lifetime — to believe that a truth booed today will remain so forever. Condemn me if you will; but keep my maps and my fossils. They will plead my case better than I when I am no longer here.
