Supernova outside galaxy proves the existence of rogue stars.

 Supernova outside the galaxy proves the existence of intergalactic stars.


There are stars in the universe that are connected with any star cluster. Those stars are traveling outside galaxies. And then someday they finish their lives like all other stars. There is the possibility that small interplanetary nebulas are forming those stars. The origin of those nebulas might be in the eruption of the stars in open star clusters. Or maybe the large explosion in some galaxies is pushing those stars away from galaxies. 

The fact is that distance to those objects is so huge that they are hard to see. The rogue stars might have planets and they might be otherwise similar. But those stars are not located in galaxies. There is the possibility that there are lots of rogue stars orbiting the galaxies outside the main material disk. And confirming the existence of those cosmic travelers is interesting. 

There is the possibility that stars form also outside galaxies. And the interplanetary nebulas that form stars can travel from another galaxy. The disturbance that the radiation of the galaxy causes will turn gas and dust into the star. 

The measurements are showing that most of the intergalactic stars that are orbiting the Milky Way have an origin in a Milky Way. But there is an interesting vision. That there could be stars that have the origin in other galaxies. Proving that thing is very difficult. That requires the mapping of the elements in the star. And then there must be the galaxy that material has the match with those measurements. 

There are lots of intergalactic stars. And those measurements require complete knowledge of the relationship of the elements in the Milky Way galaxy. The relationship of the elements is different on every side of the Milky Way. That means compiling the Milky Way's composition of the material is not possible the best possible way to uncover the origin of the rogue star. 

When we are saying that a rogue star travels from another galaxy. that travel can happen in the form of the planetary nebula. Then the disturbance of incoming material of the Milky Way turns that material into the star and possible planets. Another thing that can travel from another galaxy is a black hole and neutron star.

Schrödinger's cat: and the limits of that idea.

"In quantum mechanics, Schrödinger's cat is a thought experiment concerning quantum superposition". (Wikipedia, Schrödinger's cat). But the same thing can use as model for many other thought experiments.  Sooner or later, or at least in the ultimate end of the universe, the Schrödinger's cat will turn into wave movement. The information that this cat involved exists but the cat does not exist in its material form. The information doesn't ever vanish. It just turns its shape.  We are all trapped in the universe and time. The universe is the space that is entirety to us. There are no confirmed other universities. But the multiverse is a logical continuum for the expanding galactic megastructures.  The problem with natural things is this. They are black and white. They exist or do not exist. Could there be something, that exists and not exists at the same time?  Scrödinger's cat is thinking experiment about case their cat is not dead or not alive. But in this...

The string theory offers a new way to calculate Pi.

"Scientists discovered a new series for pi through string theory research, echoing a 15th-century formula by Madhava. By combining Euler-Beta Functions and Feynman Diagrams, they modeled particle interactions efficiently. Credit: SciTechDaily.com" (ScitechDaily, String Theory Unravels New Pi Formula: A Quantum Leap in Mathematics) People normally think that. The pi is the ratio of the circumference circle's circumference to the circle's diameter. The Pi is a mathematical constant 3.14159..., the endless decimal number. The Pi is interesting because developers can use that decimal number to make the encryption algorithms stronger.  The idea is that the encryptions program hides the message's original ASCII numbers by multiplicating those numbers with some decimal number. Or the system can add some numbers to those ASCII numbers.  "Aninda Sinha (left) and Arnab Saha (right). Credit: Manu Y" (ScitechDaily, String Theory Unravels New Pi Formula: A Quantum Le...

There are always more than three actors in the real world.

"An international research team is advancing precision timekeeping by developing a nuclear clock using thorium isotopes and innovative laser methods, potentially transforming our understanding of physical constants and dark matter. (Artist’s concept.) Credit: SciTechDaily.com" (ScitechDaily, Unveiling the Thorium Nuclear Clock and Its Time-Twisting Secrets) From Three-body problem... There are no pure three-body systems in nature. There are always more than three components in the system. For making real three-body systems we must separate those three bodies from the environment. Otherwise, there are stable effects. But nobody can predict some effects like distant supernova explosions or sun eruptions.  And one of those things that affect all bodies is time. When radioactive materials decay. That affects the stability and symmetry of the object.  Energy levels affect the existence of things like neutrons. The thorium atom clocks are next-generation tools for time measurement....
