The initial collapse of a solar-mass protostellar nebula takes around 100,000 years.

More Palace continued to cave in around the initial collapse.

The Sun and other main-sequence stars are produced by the initial gravitational collapse of a giant molecular cloud.

Soon after Napster's initial collapse came the decentralized peer-to-peer networks that are now at the center of the debate.

Extending this logic to the coronary arteries, here is a song that, in many cases, may have triggered the initial collapse.

Debris continued to fall in the tunnel for up to three hours after the initial collapse.

The initial collapse of the core is quite fast; time 1/ (6.7x10x10 g/cm3) 50,000-100,000 years or so.

The initial collapse takes about 100,000 years.

During the initial collapse, this pre-main-sequence star generates energy through gravitational contraction.

This piece remained standing for a few seconds after the initial collapse before it also came down.
