<div>Three hundred years ago, we thought gravity was solved on Earth. Newton gave the math, Cavendish built the first torsion balance—two lead balls on a wire, measure the twist. Gravitational constant G. Mass attracts mass, inverse square, universal.
</div>
<div>In 1972, Apollo 17 deploys the Lunar Surface Gravimeter for precise lunar gravity. Calibration weights too light for 1/6th g. Beam won’t zero. Assumptions fail.
</div>
<div>We’re fixing that—building a torsion beam balance to measure real mutual pull on lunar regolith.
</div>
<div>Where we stand:
</div>
<div>•  Design locked: aluminum rod, quartz fiber, laser readout
</div>
<div>•  Materials sourced: fiber, mirrors, sensors from UK suppliers
</div>
<div>•  Printing &amp; fab lined up: hybrid mounts, no sag
</div>
<div>•  Collaborations brewing: UBC (Vancouver) and University of Southampton
</div>
<div><br />
</div>
<div>Where the money goes (transparent):
</div>
<div>£9,500 total—broken down:
</div>
<div>•  £4,000: Precision optics, quartz fiber, sensors
</div>
<div>•  £2,500: Vacuum chamber parts &amp; regolith simulant
</div>
<div>•  £1,500: Travel &amp; outreach (UBC-Southampton meetings, influencer collabs like Scott Manley &amp; Everyday Astronaut for visibility)
</div>
<div>•  £1,000: Documentation (video, photos, logs)
</div>
<div>•  £500: Promotion (ads, reach)
</div>
<div><br />
</div>
<div>Project based in Southampton, UK—near University of Southampton’s gravity research labs.
</div>
<div>One planet isn’t enough. Direct Moon data needed. If pull changes in dust, laws aren’t universal.
</div>
<div>Regular updates: progress, setbacks, results, spending.
</div>
<div>Help us build the test Apollo never could
