Gravitational Waves

Gravitational waves produced by two orbiting bodies.

Description

Gravitational Waves are visualized using Lyrca fabric, a source simulating two orbiting bodies, and a stroboscope. Please note this demonstration is large, has many pieces, and requires sufficient transport and assembly time. This demonstration shares many of the same components as the Gravity Simulator demonstration to visualize how masses bend spacetime.

Purpose

To help understand and visualize gravitational waves.

Apparatus

  • High speed cordless drill
  • Machined piece with two adjustable ball casters.
  • Lycra style fabric.
  • Circular wooden ring to attach fabric onto.
  • Clamps to secure fabric under tension.
  • PVC pipes for support legs of the wooden ring.
  • Stroboscope

Machined piece to insert into cordless drill for simulating orbiting bodies.

Stroboscope

Complete setup.

Setup

  1. Attach PVC pipes to large wooden ring so that ring can stand on the floor.
  2. Lay the Lycra fabric on top of the ring and clamp it providing tension to the fabric.
  3. Attach the machine caster piece (two orbiting bodies) to a cordless drill.
  4. Place the stroboscope so that the fabric will be illuminated.
  5. Place the machined piece on the fabric and press the drill to generate waves.
  6. Match the frequency of the drill and the stroboscope so that the waves appear to move in slow motion.

Notes

Any additional notes that don't fit in the above sections can go here. Helpful links, background information, whatever you feel like adding.

Safety notes can also be added here or in the description. Use this one if theres a potentially fatal hazard like high voltage,

and this one can be used for less frightening things.
