Do Aliens Exist?

TRAPPIST-1 system compared to the Solar System; all seven planets of TRAPPIST-1 could fit inside the orbit of Mercury


I think aliens do exist. I mean, out of the trillions and trillions of stars and planets, how can aliens not exist?  There must be some planets that are habitable out there. There is already a search for extra-terrestrial life. And there are also a lot of movies about aliens (my favorite is “Stranger Things” series). They could be even way more advanced in technology than us. They might even visit us soon. Maybe they already visited us.

For children, they know the cute little green alien. But for adults, the aliens really look like an alien from another planet. They are pretty scary. Sometimes in the movies they help mankind, and sometimes they assault us.

The Great Pyramid of Giza is the only Pyramid discovered to date which in fact has eight sides. The four faces of the pyramid are slightly concave, the only pyramid to have been built this way.


I think aliens have already once visited us, on Earth! I don’t think that the Egyptians could have built the Pyramids on their own. Could it be an alien? Back then, they didn’t even have rulers! What’s more, the Great Pyramid of Giza isn’t just a square when seen from the top. It looks a little like a four pointed star.

There is a search for extra-terrestrial life now. Now astronomers have found out that there are other Earth – like planets, such as the recent discovery of the Trappist solar system. There might be aliens there. Maybe, now they have evolved well. However, there can be many forms of them. It could be bacteria, or some advanced technology civilizations, or perhaps even human-like creature residing on another planet.

Voyager 1 Golden Record, Earth's greeting to the Universe

When NASA sent Voyager  1, they put a disc that says “hello” in 55 different languages. They also put a picture of the human body, so if the Voyager reaches another planet one day, it will be like if we are introducing ourselves. They will hopefully understand our language, or understand the scientific message on the disc.

We are also improving our rocket fuel technology, so one day we can travel in space with light-speed velocity or even better with the warp engines that have been introduced in movies. Either way, I believe one day we Humans will encounter another living organism from another solar system or galaxy. Although it seems far away, I’m just hoping that will happen during my lifetime.

Thank you - Nat

“In the great dark between the stars there are clouds of gas and dust and organic matter. Dozens of different kinds of organic molecules have been found there by radio telescopes. The abundance of these molecules suggests that the stuff of life is everywhere. Perhaps the origin and evolution of life is, given enough time, a cosmic inevitability. On some of the billions of planets in the Milky Way Galaxy, life may never arise. On others, it may arise and die out, or never evolve beyond its simplest forms. And on some small fraction of worlds there may develop intelligence and civilizations more advanced than our own.” – Carl Sagan, Cosmos.

Vectors and Scalars

I want to talk about Vectors and Scalars . This is about physics. Now you might be asking, what is a vector? Vectors have a magnitude and direction. In case you don’t know, magnitude is the size of the movement, but it’s not distance. Since it’s a vector quantity, it’s called displacement .  For example, the displacement of a leaf being blown by the wind is 50 centimeters to the east. This is a vector quantity because it has a magnitude (50 cm) and a direction (east). And there’s more...  If someone asks you the version of speed in a vector quantity, it’s called velocity .  For example, the velocity of a ball being thrown is 5m/s to the east. In other words, five meters per second to the east.  You can find the displacement as long as you have the velocity and time. Multiply them and you will get the displacement. If the velocity is 5m/s and the time is 10 seconds, you need to multiply them ( 5 x 10 ) to get the displacement, which is 50 meters.  A...

Cheryl's Birthday Problem (from SASMO 2015) and Solution

Image
Hello! Nat here, and in this blog, I am going to discuss and give the solution to the famous Cheryl birthday problem. This was popular because it is a difficult logic puzzle and involving the ability of carefully tracking down hints in the conversation and working with only a small amount of data. Here’s the question: Albert and Bernard just became friends with Cheryl, and they want to know when her birthday is. Cheryl gives them a list of 10 possible dates. May 15           May 16           May 19 June 17          June 18 July 14           July 16 August 14       August 15       August 17 Cheryl then tells Albert and Bernard separately the month and the day of her birthday respectively. Albert: I don’t know when Cheryl’s birthday is, but I know that Bernard doesn’t know too. Bernard: At first I don’t know whe...

Black Holes

Image
Black Holes are holes in space that absorbs anything in their way, even stars. They are made by a star exploding as supernova and the star must be about 3 times the mass of the sun. This is called the Oppenheimer-Volkoff limit.  Its core will collapse into a neutron star, but its gravity is so strong that it starts sucking in material from outer space and later turns into a black hole.  Once they absorb enough matter to become powerful and massive, they can start creating galaxies. That is why black holes can be found in the heart of galaxies.  Sometimes, black holes will emit the brightest light waves in the universe – quasars.  Now you might be asking, why don’t we see like “blink, blink” from earth? The answer is that they are very far. The furthest quasar from us is about 14 billion light years away. However, we are lucky to be on a planet that isn’t near a black hole. If we were near a black hole, we would get our atmosphere stripped first then ...
