The continuous stream of particles flowing outward from the Sun was first suggested by British astronomer Richard C. Carrington.

A paper published in September 2012, scientists reported a surprise sudden decrease in charged particles flowing outward from the Sun, and a sudden collapse in the solar wind which left researchers without a working model for the outer Solar System.

On its journey, the Stardust also spent 195 days collecting particles flowing through the solar system from stars far out in space.

It is possible to construct a kind of moduli space of n-dimensional Riemannian manifolds, and then the Ricci flow really does give a geometric flow (in the intuitive sense of particles flowing along flowlines) in this moduli space.

The particles flowing around it were occasionally deluged with bursts of static, interacting with the gas giant's magnetosphere to stir the dust grains into aberrant patterns, looking like the spokes of a massive wheel.

For particles flowing in a tube, there is a net hydrodynamic force that tends to force the particles towards the center of the capillary.

Consequently, there are no charged particles flowing through the gas, and the light goes out.

One cube might correspond to all the particles flowing downward in the bottle, another cube might correspond to a near uniform distribution of positions and momenta.

On the way, it measured the solar wind, a constant stream of charged particles flowing outwards from the Sun, confirming the measurements by Luna 1 in 1959.
