‘To the stars, in steps, with each step larger than the last.’
Going to the stars is not likely to be due to a single grand breakthrough, but rather the result of thousands of small, incremental discoveries which build upon each other.
The goal of the Tau Zero Foundation is to encourage and enable those early steps now, so that eventually the human family may complete the work of reaching nearby stars, giving our family the means to grow and thrive beyond Earth.
