Hi there. My name is Jermaine, and I’m a guy who has endless passion about plenty of things. When the writing bug hits me, it is always about the multitude of stuff I find interesting. It could be about anything from people like Stephen Hawking to Einstein to quantum physics and the many celestial bodies that can be observed using a high quality telescope.
I like writing about black holes and wormholes, space, the constellations and anything up there that completes our galaxy and beyond. I have even found myself wondering if perhaps I was a Mayan in another life because of my fascination for the sky and its inhabitants. What do you think?
Well anyway, our galaxy is not the only one of its kind. There are any number of sprawling space systems comprising the same elements as our own Milky Way, with countless stars, gas, and dust. They say we cannot know for sure how many galaxies there are.
However, our observable universe alone is known to comprise perhaps about 100 billion galaxies, with some of the distant space systems resembling our own and with others quite dissimilar. Small galaxies have less than a billion stars. Our sun is simply one of an estimated 100 billion stars.
I love it that there are three main types of galaxies that can be observed. There are elliptical galaxies, spiral galaxies, and irregular galaxies. It’s wild to watch how a galaxy’s disk can include gas, dust, planets and stars, which is fantastic because of how this gives me plenty to look at up there.
All of the gas, dust, etc. rotate in a regular fashion around the center of each galaxy. The spinning motion occurs at hundreds of kilometers of speed per second, causing matter in the galactic disk to assume a spiral shape that looks like a fantastic cosmic pinwheel.
We can even find spiral galaxies with more delightful shapes that give them awesomely descriptive names including sombrero galaxies and others.
It is interesting to know that older stars are situated in the bulge that is found at the galactic disk’s center. Plenty of new stars in spiral galaxies have disks enclosed by a halo, which are believed by scientists to be full of special dark matter.
The shape of elliptical galaxies is as their name suggests. Elliptical galaxies are typically round but have a characteristic more stretched form along one axis compared to the other.
I am fascinated by Stephen Hawking because he is a brilliant cosmologist who has not allowed amyotrophic lateral sclerosis (ALS), a progressive neurodegenerative disease, to weaken his intellectual faculties. In fact, despite or even because of the disease, Dr. Hawking continues to be famous today.
Some even think he wouldn’t be as famous today if he did not carry the disease. Suffice it to say, his accomplishments are made even more spectacular because they are not from an able-bodied individual but from someone afflicted with motor neuron disease.
The mysticism of such an image with such a powerful mind trapped in a body rendered immobile is a remarkable thing. However, I would like to think that Dr. Hawking’s stability is not the only thing that has made him significant. He is such a brilliant scientist that it would take more than the film The Theory of Everything to enable us to see how great a mind he has.
German-born theoretical physicist Albert Einstein, who developed the general theory of relativity, formed one of the two pillars of modern physics, the second of which is quantum mechanics. The evolution of quantum theory would not have happened without him.
The explosive combination of physics and cosmology makes it quite exciting to own a quality telescope to study the movement of different heavenly bodies and plenty of other concepts that we can observe more carefully.
