sentient uranium cube

• Communicates by fluctuating the emitted radiation levels. If it can be called communication - it just outputs data.
• (it means that by communicating, it is slowly 'killing itself')
• Bombarding it with neutrons to make communication two-way yielded no results.
• Bombarding it with electrons caused it to emit garbled, nonsensical output.
• (it causes it to suffer)
• Seems to shift slightly in size and proportions - but the fluctuations are minuscule, detectable only by laser measuring devices.
• It generates long and complex mathematical equations, as well as their solutions.
• Sometimes its output resembles sentences. So far the only thing we managed to determine except the numbers (it uses septenary system) is the punctuation.
• The cube asks lots of questions.
• Its sentience isn't confirmed - but the name - originating from the title of the first paper published after determining the punctuation of its 'sentences' - stuck. 
• Discovered somewhere in the REDACTED by Sol.
