Here’s a new one for coffee hour: Rogue planets


Planets like ours but they do not follow a star:

Rogue planets are elusive cosmic objects that have masses comparable to those of the planets in our Solar System but do not orbit a star, instead roaming freely on their own. Not many were known until now, but a team of astronomers, using data from several European Southern Observatory (ESO) telescopes and other facilities, have just discovered at least 70 new rogue planets in our galaxy. This is the largest group of rogue planets ever discovered, an important step towards understanding the origins and features of these mysterious galactic nomads.

Polistra, great post. aarceng
",,, I don't believe in this wave-particle duality mumbo jumbo. I think is is mostly just left over baggage of having started off understanding the world as particles, and then being forced, because of the quantum revolution, to view the world in terms of waves. And we are stuck with this dualistic way of looking at these very small particles. Don't even think about them as particles. Electrons are waves. And if you think of them in terms of waves, you will always end up with the right answer. Always!" - Don Eigler - IBM Physicist - Discovering Science: Uncertain Principles – video - 25:00 minute mark https://youtu.be/iu6kqO4L0KQ?t=1471 In 1989, Eigler was the first to use a scanning tunneling microscope tip to arrange individual atoms on a surface, famously spelling out the letters "IBM" with 35 xenon atoms. He later went on to create the first quantum corrals, which are well-defined quantum wave patterns of small numbers of atoms, and nanoscale logic circuits using individual molecules of carbon monoxide. He shared the 2010 Kavli Prize in Nanoscience with Nadrian Seeman for these breakthroughs.[1] https://en.wikipedia.org/wiki/Don_Eigler
Polistra, you do realize that the comparison between atoms and solar systems is a very rough, even archaic/materialistic, comparison that has now been overturned by advances in quantum mechanics do you not? i.e. Specifically in the 1920s, In the modern Electron Cloud Atomic Model, "Erwin Schrödinger proposed that electrons travel in waves, which means their exact positions cannot be determined".,,, "This model is still accepted by scientists today."
The History of the Atom - image http://thehistoryoftheatom.weebly.com Electron Cloud Atomic Model Excerpt: Where Are the Electrons?,,, Summary Bohr’s model of the atom, in which electrons circle the nucleus at fixed energy levels, cannot explain all the behaviors of electrons. In the 1920s, Erwin Schrödinger proposed that electrons travel in waves, which means their exact positions cannot be determined. He developed an equation to calculate the chances of an electron being in any given place. Using his equation, he identified regions around the nucleus, called orbitals, where electrons are most likely to be. Orbitals are the basis of the electron cloud model of the atom. This model is still accepted by scientists today. https://flexbooks.ck12.org/cbook/ck-12-middle-school-physical-science-flexbook-2.0/section/3.17/primary/lesson/electron-cloud-atomic-model-ms-ps/ Theory of Uncertain Principles - (The "Non-Particle" Basis Of Reality) – video 24:31 minute mark Discovering Science: Uncertain Principles - video https://youtu.be/iu6kqO4L0KQ?t=1471 Depiction of 'non-particle' atom, http://researcher.watson.ibm.com/researcher/files/us-flinte/stm15.jpg
This raises a question. After a solar system loses a big electron, is the system a big ion trying to attract another big free electron? polistra
