Fun Tour : Galaxies with Nate

Galaxies are the huge, gassy, and massive things that fly around in space.  They are quite massive because they have a LOT of stars inside. They also hang around in groups! Now we will have a tour on galaxies and ‘talk’ to them personally!


The Milky Way
Hello! I’m the Milky Way and I’m the home of your precious star, The Sun! Deep in my center, I have a Supermassive Black Hole! I’m very thin like a disk and I’m only 1,000 light years (ly) thick. My bulge in the middle is 3,000 ly thick. However, I’m 100,000 ly across, which is really long! The Sun actually travels at 220,000 km/h! That’s because it’s orbiting my center!


Andromeda Galaxy or M31
Good day! I’m your galaxy’s closest neighbor even though I’m still very far! However, I’m on a crash course with your galaxy because I’m a bit too close for comfort. For more information, see Colliding galaxies. Our new galaxy will be an elliptical galaxy called… ‘Milkdromeda’? Yeah, I know. It's uncreative, just compromised. Our black holes could merge together too!


Triangulum Galaxy
Hey there! The Milky Way, the Andromeda Galaxy and I are the three major galaxies of the Local Group! Together we form 95 percent of our Local Group. Even though I’m pointed to the Milky Way, not much is known about my stars! I don’t do too much in the Milky Way and Andromeda’s collision though! Remember I'm a 'major' galaxy and I'm massive like your galaxy!


The Local Group
Welcome to me. I hold the Triangulum galaxy, the Milky Way and the Andromeda galaxy! Most of my mass comes from those 3, while I consist of 43 galaxies! I have a lot of minor galaxies as well so don’t forget them! Some of the famous minor galaxies are the Small and Large Magellanic Clouds!
There are other groups as well that are bigger and smaller! Here's an example of a bigger group: Virgo Supercluster. I'm actually slowly running into it right now!

All right, that’s everyone we can talk about in the knowledge of galaxies. As Andromeda said, to see how galaxies collide, look at my blog! And I promise that if I get any new ideas, I will make a blog about it. I promise you, it’s going to be FUN!

Thanks for reading! - Nat

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 ...
