Looking at what is known about the cosmos leads to an obvious conclusion: the universe shows trillions of years of evolution. Considering what is unknown, an eternal universe is likely.

Gas comprises over 75% of the detectable matter in the universe. As the universe supposedly expands, conventional astrophysics theory figures the gas ought to cool down. Instead, it’s getting hotter, according to the latest guesstimate.
Light and gravity may seem to have nothing in common. But, inspired by the singularity of a black hole, the quanta by which they manifest may transmigrate.
Through a natural force of coherence, life adapts to its environment to enhance survival. This evolutionary impetus starts at the molecular level.
As its fundamental foundation, the standard cosmological model assumes that the universe started 13.82 billion years ago, based upon the first light detected by a space telescope. Instead, the cosmos is much older.
Neutron stars are the densest matter aggregate in the cosmos. Black holes go one better by being holes in the fabric of spacetime. Yet these dark demons generate tremendous light. It’s all in the spin.
The interstellar medium is a thin gruel of gas and dust that occasionally clumps together, eventuating in star formation. Magnetic fields mystically permeate the interstellar medium and shape the cosmological future.
More evidence that the Big Bang hypothesis is blown.
The overall geometrical shape of the cosmos is a primary attribute indicating its overarching dynamics. The universe has long been presumed flat: existence ultimately planar owing to a sweet-spot matter density that altogether avoided curvature. Einstein’s general relativity equations predicated a slightly open universe, with external expansion gradually slowed by gravity. Recent measurements suggest instead a positive cosmic curvature which blows apart extant cosmological models.
The heliopause is the boundary between the solar system and interstellar space.
Astrophysicists are muddling their way through a gross discrepancy related to their gross misapprehension of how and when the universe began.
Astronomers have discovered a massive galaxy that is at least 12.5 billion years old. According to the standard cosmological model, that’s impossible. What’s actually impossible is the standard cosmological model.
According to a conjecture called cosmic inflation, just after the Big Bang, before many of the fundamental physics forces had even taken hold, the size of the universe mushroomed from next to nothing to the size of a dime; at an expansion rate faster than the speed of light.
The vast expanse of interstellar space is supposed to be too cold for most chemical reactions to occur. The more frigid it gets, the harder it is to spark a chemical reaction, for lack of energy – the very definition of cold. Yet a vast variety of complex organic molecules are formed in space. Some reactions transpire on the surface of cosmic dust grains, or with a little help from gamma rays or stray high-energy electrons. But most happen beyond the laws of chemistry.
That complex life could evolve on Earth involved a set of fantastic coincidences. One of them was the prolonged pummeling of the planet for 800 million years, starting over 4.5 billion years ago. Seeding the planet with cosmic debris was essential to its evolution, as was what was taken off in the process. One benefit of bombardment was ridding Earth of most of its chlorine.
The solar system’s innermost planet has the most eccentric orbit. It wobbles around the Sun every 88 days, with one-and-a-half rotations during that time. Mercury’s temperature range is also the most extreme: from 700 K during the day to 100 K at night. Yet it likely has life.
