Re: CoRoT Rocky Planet (APOD 2009 September 23)
I have discussed elsewhere that some identifications may be wrong. This may just be a decrease in brightness of a related star. Think logically, could a star's brightness decrease in a regular way? Yes. I do not have the measurements in front of me, but I still maintain that there is a possibility t...

Star Definitions Unclear As Well
There are definitions of stars that say they are objects with reactions in the core that radiate light. Jupiter, Neptune, Saturn, and even Earth meet that definition. It is just as likely to end up that the object is a double star. There are cool stars. That near infrared spectra is probably also se...

Further one gains an understanding that ellipticals and barred spirals could have similar vortical structure like a Bernoulli equation logarithm. I do want to say that not all spi...

Looks Like C and D Dimmed and A Brightened
I am not sure this is not a novae rather than Supernovae. Look at C and D dimming with A brightening. Why Supernovae versus novae. Has this been seen by many observatories? SN 1987 A certainly was, but has this been observed multiple times. I learned this summer how our constitution is about the rig...

Carina Nebula Illuminated by Einstein's e=mc2 (25 Apr 2007)
I was just talking yesterday about a Physics Today submission I did last December or November that the real point of e=mc2 is that radiation has an inertia.

Asteroids/Comet/Meteroid Impact Surface--More exposure
My own hypothesis is exposure of the far side to asteroids, micrometeroids and comets. The concept is that collision frequency is just higher on the far side. The earth's atmosphere burns up meteroids on a monthly basis. These do not then collide with the moon. The other concept is that there are mo...
