Hafnium carbide currently has a thermal expansion coefficient of 600 MK^-1. This is many orders of magnitude greater than other similar materials (e.g. Hafnium Tantalum carbide), and seems a bit suspect.
We dig deep down into the very building blocks of life, seeking to twist them to our will. We destroy mass itself to turn its energy to our ends. The speed and intelligence of our machines grows without bound. But even the power of gods isn't enough. Ever hungry, we turn our eyes to the stars...
I sure hope there's someone else more advanced out there. If we're the first, the universe is screwed.
