Multiverse Theories: Are We Really Alone in These Endless Universes?

Hey, hey, heyyy, Twiskies! Back with me and my another astronomy talks. Today's talk is about conspiracy theories of multiverse! Do you believe in multiverse, Twiskies?

So, first of all, let me explain you about multiverse just in short. Multiverse is a hypothetical concept stating that our universe is just one of many universes that exist, which together form a larger set. This concept encompasses everything that exists, including space, time, matter, energy, information, and the laws of physics that shape them. Okay, I think I already tell you about the definition of universe crystal clear. Now, let's go to the main topic, but first of all, I'll just tell you the top three of  the most popular multiverse theories.


1. Wormhole Theory

I'm so sure all of you, Twiskies already heard at least once about this theory. Why? Because this theory was first coined by Einstein in 1933, at this time, this theory almost a century old! Just like the picture above, picture spacetime as a flat sheet of paper this theory explains how a 'wormhole' could makes - we can call it a shortcut that allows us to travel around the 'paper' if we get into this hole. But, the main issue is that traversable wormholes require "exotic matter" with negative energy to remain stable, which we have never encountered and may not exist. Even if wormholes are mathematically conceivable, they will most likely be unstable or tiny.

2. Quantum Mechanics (The Many Worlds Theory)

Twiskiess, this theory is one of my favorite, because it's so mind-blowing! This theory first proposed by Hugh Everett in 1957. Unlike the previous theory that more like.. theoretical... this one explaining the possibility of multiverse in daily life activity. This theory explains how all of activities we do or decision we made could be has another possibility. Am I explaining it clear enough, Twiskies? Let me give you a simple example then. When you decide to be friend with someone, there's another possibility that you didn't have a courage and in the end you won't be friend with them, or maybe even being their enemies with them in another universe. Like that, Twiskiess.. Please tell me if I'm being convoluted with my words T^T

3. Universe Bubble Theory

This one is cute, isn't it, Twiskies? hehe. The bubble universe theory proposes that our universe is merely one "bubble" in an endless multiverse. During the big bang, different parts of space expanded at different rates, resulting in distinct bubble universes with perhaps different physical rules and constants. Each bubble is causally separate from the others, rendering this theory mathematically conceivable but not currently tested.

The Brightest Star in Orion Constellation, Rigel!

Source: astropixle.com Hello, Twiskies. I'm back with another interesting information about astronomy. Now we're gonna discuss some facts about Rigel, the brightest star in Orion constellation. A little funfact, Rigel is my most favorite star, Twiskies! Okay let's start our journey to Rigel, Twiskies! Rigel is a blue supergiant star in the constellation Orion. The Bayer designation is β Orionis, Latinized to Beta Orionis and shortened as Beta Ori or β Ori. Rigel is the brightest and most massive component, as well as the eponym, of a stellar system including at least four stars that appear to the naked eye as a single blue-white point of light. This system is located roughly 860 light-years (260 pc) from the Sun. 1.  Rigel vs Our Sun Rigel is the brightest star in the constellation Orion. Rigel's brightness is equivalent to 40,000 times the brightness of the sun! Rigel also has a much larger diameter than the sun, which is about 78 times larger than the diameter of the ...

Twiskies, Let's Get to Know Pluto Better!

Hemloo, Twiskies! Now we're going to talk about Pluto. Are you curious about Pluto? Why does it not considered as our ninth planet anymore? or why it named 'Pluto'? Who named it? Well I'll tell you about that today! Pluto by dotteshippo in  istockphoto.com The International Astronomical Union categorized Pluto as a dwarf planet in 2006 due to the possibility of additional objects crossing its orbit. Pluto's width is only roughly 1,400 miles. Pluto is only roughly half as wide as the United States at that tiny size. Its sparse atmosphere, which is primarily made up of carbon monoxide, methane, and nitrogen, is located at 3.6 billion miles from the Sun. Pluto's average temperature is -387°F (-232°C), which is too cold for life to exist there. Pluto's Name Pluto was named by 11-year-old girl. Venetia Burney of Oxford, England, proposed to her grandfather in 1930 that the Roman deity of the underworld be the name given to the new discovery. The name was chosen a...
