Heavy Metal Planet Ping!.....................
Can someone please explain to me how they know that celestial bodies have light or heavy elements? What types of instruments do they use or is it a calculated math equation on a white board. I've never understood it.
I get the doppler affect that shows movement. I get the infra-red spectrum of light. I don't get this. Help.
Astronomers forced to eat crow after discovering an unusual exoplanet in Corvus.
Another day, another theory shot to Hades.
This is typical for a profession that needs undetectable things to make its theories work.
Ah, don’cha just love settled science?
A phD student is considered an authority. The fact is that students and professors actually don’t really know how planets form. The only theory they have is the accretion disk theory. Everything starts from a swirling cloud of gas and dust that gets formed into balls that shrink until they squish down past solid and all the way to molten before cooling off at the surface. All the massive elements go down to the middle and all the light stuff ends up on the outside. After billions of years it seems very logical because you have given the matter time to sort its elements by mass. I am wondering what theory they will come up with after the precious accretion disk theory doesn’t offer a simple explanation.
I didn’t read where they ruled out planetary capture. An errant planet could have been captured by a star that could never have formed it.
