SHOWING: First 60
## **Field notes, site F, 24/03/28**
While we wait for permission for destructive sampling of the specimen, we have busied ourselves with what we can do with our callipers and balance. Last night I recorded the diameter as being an average of 27.8 millimetres and the mass as being 14.2 grams. I am wary of the risk of corrosion so we have not measured the volume.
The wait to hear back from the Department has been excruciating and such was my restlessness that today I asked Aisha to make the same measurements again. She indulged my need to be *busy* with something and did so.
Her measurements were different. The coin was now 28.8 millimetres and 14.7 grams. I almost shoved Aisha out of her chair and measured the thing again myself. I recalibrated the balance and had Aisha walk outside the encampment to witness that there were no planes flying overhead or lorries going past, nothing creating any unusual vibration that might disturb the balance. Even so, the callipers stubbornly reported the same, increased, diameter.
The coin has changed size. It has increased in mass, somehow. Overnight.
To add a mass of half a gram to an object would require 45 billion kilojoules of energy, according to Einstein. The Zaporizhzhia Nuclear Plant, worryingly close to the site, can generate 950 megawatts of power at full capacity, which at present it certainly does not. But if it were to run at full capacity for thirteen hours, it would generate about as much energy to produce the mass to add to the weight of the coin. Silently, without either of us noticing from our tents.
I told Aisha that the coin could very well be a hydrogen bomb and she ceased to humour me. It is clear that her patience with me is at its limit.
I hiked out to the summit to catch a connection to a satellite in the hope that emails from the Department would come through more quickly that way. It was only when I reached the hill that I realised what a strange thought that had been.
When I returned I measured the coin again and found that another 15 billion kilojoules of energy had struck the thing and left it heavier. I decided to not trouble Aisha with that update.#70,643,447text
