Top 10 Bizarre Space Phenomenon
Space is a boundless, three-dimensional expanse in which objects reside and events take place. Many experts consider space as a separate entity while others define it simply as a conceptual framework. Regardless of what space is, it is an amazing place where many bizarre phenomenons occur:
Hypernova is an extreme form of supernova and it occurs when a very massive star collapses. This kind of stars is very rare and hypernova may occur every 200 million years on average galaxies like Milky Way.
Quasars are bright beacons that shine on us from afar and they are more powerful than hundreds of galaxies combined. Experts have discovered more than 200,000 quasars and most of them are farther than 3 billion light-years away. Although they are invisible to naked eyes even during the clearest, darkest night; astronomers consider them to be the most luminous objects known.
3C 273 is among the brightest quasar, it is 2 trillions times more luminous than our sun or emits 100 times more light than our Milky Way galaxy.
8. Cosmic Microwave Background
In 1960, a strange radio noise was detected from the outer space and it seems to be almost uniform in all direction, which means it has no real source. Physicists believe that Cosmic Microwave Background could only be a leftover from the biggest explosion ever, the Big Bang. In fact, this phenomenon is now considered as a direct evidence of the Big Bang.
7. Gravitational Waves
Like visible light, gravity is among the most observable phenomenon in the universe and it keeps us from floating freely in the air. Gravitational waves radiate from anything with mass, the larger the mass, the more intense gravitational waves. Sun, Earth and even individual human exert gravitational pull; they can penetrate any solid object, one thing that electromagnetic waves can’t do.
Neutrinos are virtually mass-less and electrically neutral elementary particles that can pass through miles of solid objects unhindered. These “mystery” particles are created in the core of a huge, healthy star as well as a supernova explosion. Neutrino detectors placed beneath the sea and embedded deep underground solidly prove its existence. For every square centimeter of our body, 65 billion neutrinos pass every second and luckily, they don’t interact with other matter.
5. Galactic Cannibalism
Galaxies could collide with one another, for example, the nearby galaxy, Andromeda, is currently dining on a smaller galaxy. After painstakingly track the motion of our galaxy, Milky Way and Andromeda between 2002 and 2010 using the Hubble Space Telescope, scientists came to a conclusion that a collision between the two is imminent. However, this would happen 3 billion years in the future and once they merge, a quasar could form in the center of the newly formed galaxy.
4. Vacuum Energy
Empty space is not really empty, it is full of bubbling virtual subatomic particles that are created and destroyed almost immediately. Based on conservation principle, these particles can’t be created from nothing and since mass is equivalent to energy, there should be a form of energy that hides somewhere in the emptiness of space. Physicists call it “vacuum energy” and if it does exist, vacuum energy should be detected by its gravitational force. Apparently, the vacuum energy concept seems to be confirmed by the current expansion of the universe.
3. Dark Matter
With trillions of galaxies in space, their combined weight seems to be mind-boggling. But apparently, physicists think that the universe is far too light. To make their calculations work, scientists need to “create” a new type of matter that make up the bulk of the universe. Dark matters would explain many things we observe in the universe, including orbital and rotational speeds of each galaxy in clusters. Perhaps, dark matter is a great indicator on how little we know about the universe that we unashamedly made up a fictional object.
Anti-matter is our universe’s arch-nemesis. When anti-matter and matter combine, they annihilate each other and their total mass becomes pure energy. Based on Einstein’s iconic equation E=mc2, anti-matter is also the greatest source of energy or the most violent explosive known to man. Anti-matter could only be stored in a special container made from intense electromagnetic field to avoid contact with the physical container, which is made from matter. Consequently, anti-matter is the most expensive material to produce, which is about $25 billion per gram of positron (anti-electron). More complex anti-matter, such as one gram of anti-hydrogen, costs more than $60 trillion!
1. Life and Intelligence
After trying to understand the universe, life seems to be the most bizarre and improbable things that could arise from “dead” materials. Defining life is difficult because it is essentially a process, not a substance. However, common characteristics of life are self-sustainability and predictable behaviors. Eventually, some of these “life-forms” develop the ability to reason, solve problems, plan, comprehend complex ideas, learn from experiences and think abstractly.
