Planck Time โ Number Length Visualizer
An interactive visualization designed to make the extraordinarily small scale of Planck time easier to understand.
Planck time is approximately 5.39 ร 10โปโดโด seconds, which can be written in decimal form with 43 zeros before the significant digits 539.
Explore its numerical length, travel through nearly 44 orders of magnitude below one second, compare it with nanoseconds and attoseconds, and discover its relationship to the Planck length and the speed of light.
The visualization uses logarithmic scales and animated comparisons to provide an intuitive perspective on one of the smallest meaningful time scales used in fundamental physics.
SETI Cosmic Signal Listening Lab
An interactive radio astronomy experience that simulates how SETI researchers search for unusual signals hidden within cosmic radio noise.
Explore a dynamic 3D waterfall spectrogram, spectrum analyzer, and oscilloscope while listening to synthesized radio signals generated directly in the browser.
Use the built-in receiver and synthesizer controls to adjust frequency, bandwidth, noise, signal strength, volume, and scan speed, and observe how each setting changes both the sound and its visual representation.
The simulation is designed for educational exploration and uses synthetic signals rather than real extraterrestrial transmissions or live SETI observation data.
