How are galaxies formed?

Hi my name is Jayden, this is my podcast it is about how to count to 70! First 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15, nah not really my topic is how galaxies are formed, so first a galaxy starts out as stardust and over time it sucks stuff up, and gets bigger every time, and after some billion years you will have a new galaxy! Will we ever make it to another galaxy, as sad as it is, most likely not. Why? Well because going as fast as we can now it would take 770,000,000 years, and if even we can figure out how to go the speed of light, it would take 77,000 years. Ok that’s all, Thanks
