Science and Astronomy Questions

Gravitational waves were detected from a neutron star merger. 11 hours afterward, a nova was seen in visible-light from a location in the sky consistent with the source of the g-waves. X-ray and radio emission were then seen over the next few weeks, and SWIFT detected a gamma-ray burst from it. Thes...

Planets with potentially breathable atmospheres

I wish we could. It has enough oxygen and for now I won't complain about the CO2 being a bit high. The hitch is, and most likely in most planets we find, is in this universe SO2 is always too high. You'll have better luck if you look for places were it condensate as snow leaving the air less toxic. ...

Darn. In other news, you'll need to update Haumea to have rings. Stellar occultation observations of the elliptically-shaped Kuiper Belt object (and dwarf planet) Haumea reveal that in addition to the two known moons, a narrow ring orbits the object near the 3:1 resonance with Haumea's rotation peri...

A Cashless world would suck. My purchasing power in a cashless society will be based on my social behavior online, my Ebay rating score or how many likes on Facebook that I get for efficiently moving products or services. All transactions will be scrutinized by third parties, I wouldn't even be able...

I can't understand how rotation curves of all observed galaxies are all pretty much equally flat, except near the center, implying they all have just the right amount of Dark Matter, when they each create normal matter in star formation at different rates.
