"I was immediately enthralled by what I saw," explains Leon Kirchlechner. "An inky black hole opened up suddenly and incomprehensibly in the cold, bare ground. It appeared to swallow the light. The unstructured, almost two-dimensional black was deceptive; the thought of falling into it made me shudder. How deep was it? What was in it? Was there anything? Or nothing? I expected something. I suspected something. I knew that nothing would happen and yet I was as if hypnotised. Filled with an illusory fear I stood still – and looked at what I could not see."
