How do I simulate a Lagrange point?

Open this page and use the live Hubble's Law tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive a Lagrange point from your own measurements.

Hubble constant H₀ (km/s/Mpc)

Every distant galaxy recedes at a velocity proportional to its distance: v = H₀·d. This uniform expansion is the same seen from any galaxy — there is no center. The inverse of H₀ gives the Hubble time, a rough estimate of the age of the universe.

H₀70 km/s/Mpc

Hubble time14.0 Gyr

v at 100 Mpc7,000 km/s

Governing equation

v = H_{0} d = 70 \times 100 = 7, 000 km/s, t_{H} = \frac{1}{H _{0}} \approx 14.0 Gyr

Reading this result: Right in the Hubble-tension zone: this H₀ gives a Hubble time of 14.0 Gyr, close to the measured 13.8-Gyr age of the universe.

About this simulation

The full Hubble's Law tool models a Lagrange point with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
