Re: What happens when galactic Dark Matter haloes meet?
There isn't much (or any) evidence that dark matter interacts with itself except through gravitation. When galaxies collide, their dark matter halos do interact, which has been observed . The halos around the Milky Way and Andromeda are not large enough to have come into contact yet, or for their t...

Re: Requesting input: what needs to be answered by a new theory of star-system formation?
I don't have the time to look into tired time. We'll know it's worth investing some study time when it passes sufficient peer review in mainstream journals and acquires a degree of consensus as a viable theory. A good rule for all non-specialists. You've decided that someone else is smarter than yo...

Re: Does Antimater Repel Mater?

Re: Does Antimater Repel Mater?
I have discovered a surprising effect that I call an electron shield. If you get enough electrons spinning in a circle (in a thick enough disk), then the mass inside the circle is mostly cut off from the mass on the outside of the circle. Sally Okay .. so if the mass inside the circle is mostly cut...

Re: UMCP: Zwicky Transient Facility Sees "First Light"
I'm surprised to learn that an important instrument like this would be mounted in San Diego, which is NOT a high point and has light pollution. Is this for convenience to JPL? It is because of the availability of a large aperture, low focal length telescope at Palomar. There aren't many large Schmi...

Wow! Thanks for this post. Good to know. The website says that one pixel is 15 microns, so does that mean that this instrument is observing in mid-infrared wavelengths?

Re: NOVA: Moving Shadows around Planet-Forming Star
However, " heavy protoplanets " can project shadows onto this protoplanetary disk. According to the research paper that you reference in your first post says that the research is based on a spatial resolution of 6.4 au, that is 6.4 x 1.5 x 10^11 m = 9.6 x 10^11 m or about 1 x 10^12 m... p...

I thought about this more. I think that the scale between a planet and the protostellar disk beyond 1 au from the center, is like the relationship between a pea and the clouds in the sky.

Pretto's theory was based on his hypothesis that a mass traveling at velocity v has the potential energy[6] (forza viva) proportional to mv2 (the exact formula is ½mv2).

Researchers made a case that planets (which are on the order of 10^4 km - 10^5 km wide) can affect large-scale modifications in a circumstellar disk which has a size on the order of 10^13 km to 10^14 km (80 au to 150 au). https://www.nasa.gov/feature/goddard/spirals-dust-around-young-stars-may-betra...
