The universe is accelerating away from the center of the Big Bang.
The universe is cooling down, because galaxies are moving away from each other.
The number of stars in the sky will diminish over time, there will eventually be a few, then there will be none. This is the current theory (paraphrased) held by many scientists today, typically referred to as heat death.
I’m no scientist, but I like to visualize. Read this article: Speculative Sunday: Can a Black Hole Explode?
I was inspired, in particular by this image:
This artist’s impression shows the remains of a star that came too close to a supermassive black hole. Extremely sharp observations of the event Swift J1644+57 with the radio telescope network EVN (European VLBI Network) have revealed a remarkably compact jet, shown here in yellow. – ESA/S. Komossa/Beabudai Design
The above image is an artists rendition of the results of the data received from an “earth-sized radio telescope”. The detail is specific, even if interpreted. What I’m seeing here is a pattern. Spiral falling / contraction (gravity), with a projection of stuff out the north and south poles. This projection from the black hole is likely directly related to the consumption of the star, which we see visualised as the star being smeared in a spiral around the singularity.
This is the pattern. Gravity pulls things in on one “plane” and creates a jet stream at the north and south poles of the black hole. The jet stream is comprised of particles of matter that have been deflected or have narrowly escaped being captured by the black whole, only to be accelerated away at high speed again. Now this particular aspect of how black holes function is very interesting because the process heats up space, to the point where it could potentially create or influence the creation of stars within a galaxy. Think about that for a moment.
To create a star, or star-system, you don’t need THE Big Bang. You don’t need super-galaxies, or galaxies or star-systems. What you need is a black hole. Every star that dies turns into a black hole (or a neutron star, then a black hole).You just need a black hole to create a star, and planets, and there I suggest, life?
My hypothesis is this. Even if all our galaxies are moving away from each other over billions of years, and even though light and heat will diminish – new stars, new galaxies, and new universes will be created, just as the “first” one was. And this dimension will continue on for other new life forms to grow and learn and figure this all out all over again.
Watch Cosmos: A Spacetime Odyssey if you have no idea what I’m talking about, then come back to this article.
Note: After writing this, I read up on Hawking Radiation, and found that black holes do die if they don’t feed (on other stars), they will eventually evaporate. This is kind of poetic.
