Vast Structure of Milky Way’s Satellite Galaxies is a Problem for Dark Matter.
Vast Structure of Milky Way’s Satellite Galaxies is a Problem for Dark Matter.
Astronomers have now found that the Milky Way’s various satellite objects are actually distributed in roughly a plane at a right angle to the galactic disk in a huge structure extending 33,000 – 1,000,000 light years from galaxies centre. Astronomers were not only baffled by how well the distributions of differing types of objects agreed but have shown that material being lost by these objects forms long streams along their paths that are aligned with this plane of satellite objects showing that this structure is stable.
The alternative explanation is that these satellite galaxies and clusters formed together in a single event suggesting that, a collision of two galaxies. However all this indicates that dark matter does not exist destroying this a central tenant of the standard cosmological model.
Double Slit Experiment II
The double slit experiment is based on the wave/particle duality of subatomic particles. What is so amazing about it is that over the years it has produced results that are among the strangest in quantum mechanics. It is the king of quantum weirdness being the strangest in science. The original double silt experiment used photons of light, but later versions used electrons but the results are the same The double slit experiment is actually responsible for starting Quantum Physics.

Red Dwarf Habitable Zone Earth Size Planets are Like Venus
The Earth sits squarely in the sun’s habitable zone. A star’s “habitable zones” is the distance range around a star where planets can have liquid water on their surface. Astronomers have been excited to find that about 40% of red dwarfs have approximately Earth size planets orbiting them many of which are in the stars habitable zone. This fact has lead to the suggestion that these planet could have life on them. A new study shows that tidal forces may dry out Earth size planets orbiting within a red dwarf “habitable zones” making them more like Venus than Earth and therefore hostile to life.

Introducing the Galactic Positioning System - YouTube
Have You Ever wondered how Kirk, Packard, Archer and especially Janeway know exactly where in the Galaxy they are even when on the other side of it. They used GPS of course; not the Global Positioning System but the Galactic Positioning System which is now under development
