The idea that celestial objects exist within utterly immense cosmic structures is becoming inescapable.
- New findings in astronomy are making some astronomers doubt our basic model of the universe.
- Alignments of celestial objects suggest that they may be embedded in large-scale structures.
- Galaxies too far apart to be influencing each other are moving through space together.
A new paper suggests a primordial black hole may be making things weird at the edge of our solar system.
- Though a Planet 9 has been hypothesized, we can't seem to find it, at least not yet.
- The strange orbits of distant bodies and weird gravitational anomalies beg for an explanation.
- Scientists propose a hunt for telltale gamma rays from a primordial black hole.
Our ability to make predictions about the future distinguishes our level of consciousness.
- One of the great questions in all of science is where consciousness comes from.
- When it comes to consciousness, Kaku believes different species have different levels of consciousness, based on their feedback loops needed to survive in space, society, and time.
- According to the theoretical physicist, human beings' ability to use past experiences, memories, to predict the future makes us distinct among animals — and even robots (they're currently unable to understand, or operate within, a social hierarchy).
When it comes to theories of the universe, the Big Bang theory is almost accepted as a fact. However, it's still uncertain, and some scientists believe that the universe didn't began with a bang, but a bounce.
- The Big Bang theory is treated as the de facto way the universe began, but it's had some issues.
- One issue was that it could not describe how the universe became uniform and homogeneous, which is what we observe today.
- Physicists tweaked Big Bang theory to accommodate this, but the Big Bounce theory can address these issues without too much tweaking.
When you zoom far enough out, our universe has a very unusual structure.
- Composed of massive filaments of galaxies separated by giant voids, the cosmic web is the name astronomers give to the structure of our universe.
- Why does our universe have this peculiar, web-like structure?
- The answer lies in processes that took place in the first few hundred thousands years after the Big Bang.
