As the name suggests, the superconducting super collider was a big deal, so big in fact it would have put the Large Hadron Collider to shame.
Unfortunately, the Texas-based particle accelerator was cancelled in 1993 after Congress deemed its projected $12bn price tag too expensive.
By the time the project was cancelled, 14 miles of tunnel had been dug for the accelerator and nearly $2bn had been spent on the project.
But science's loss is computing's gain - with the site now reportedly being marketed as a location for a tier III or IV datacentre.
