I guess I got reported (for some reason?) in regards to my post on how it is possible the universe is accelerating away from us???

In a nutshell:

When Einstein built his model of the Universe he assumed that the Universe must be static (so it won't collapse on itself). But Friedman found that Einstein's Static Universe can't exist because it'd be unstable. So it must be expanding. Later Hubble found that distant galaxies are red-shifted (moving away from us).

Later, in 1965 Cosmic Microwave Background Radiation was discovered. It implied that the Universe is cooling down. In the 90s Supernova observations showed that the Universe is expanding. Other observations showed that the expansion is accelerating. WMAP found that Universe is flat and there was inflation.

Anywho new images of Jupiter's Great Red Spot!

Did Jupiter's Red spot get bigger recently?

Did Jupiter's Red spot get bigger recently?

I believe there is speculation its actually shrinking

It is shrinking. You can't sustain a planet-size hurricane for that long, even on Jupiter. It's caused by pressure gradient force [Coriolis effect].
