And your evidence for that is troy?

or maybe you just don’t want to see certain principles violated, and Earth is indeed at some special place in the cosmos.

That would solve a lot of what scientist scratch their heads about, now wouldn’t it?

A quickie search says that the speed of sound at sea level = 340.29 m / s.

Good catch. Not sure how I missed that one during proofreading. The galaxy clusters are moving at about 0.003c which would be fast enough to cover the distance from the Earth to the Moon in just 38.4 seconds.

The post has been fixed accordingly.

… it looks like about 1,400 galaxy clusters are drifting some 3 billion light years at an impressive 1,000 km per second … what on Earth would be nearly supersonic speed…

A quickie search says that the speed of sound at sea level = 340.29 m / s.

Unless that “m” stands for miles instead of meters, we’ve got 1.4 kiloclusters zipping along at ~3kiloMach, which would seem to leave the hottest USAF pilots ambling behind feeling quite sorry for themselves.

At least, your previous report that neutron star RX J0822-4300 is the fastest-moving macro-scale object known still stands, unless (prob. > 0.5) my arithmetic is all screwed up again.

But to overturn them would require some direct evidence and a whole lot of study into the contradictory models of the universe.

Large Hadron Collider to answer that, maybe?

It’s supposed to restart this weekend.
