Big Bang Comic Strip Part 2
Testo Storyboard
- Hm? What's that sound? Oh, those are the Cosmic Microwave Background Waves. I'm surprised you can hear them. That's kinda weird. Anywho, the CMBWs are light waves from the big bang that slowly diminished into radio waves.
- Thank you, time travel. Okay, here we are! The start of it all. The big bang - the sudden expansion of all matter in the universe. Beautiful, huh?
- They get weaker the further you get from the big bang. This is called the Doppler Effect. The further away you get from the source of the waves, the weaker they get.
- Incidentally, a red shift is the displacement of spectral lines towards longer wavelengths in radiation from distant galaxies and celestial objects. Ha ha!
- Oh, I forgot to tell you this! It's very interesting. An Astronomical Unit is a unit of length equal to the mean distance between the earth and the sun. Yep, it's exclusive to the solar system. That's why we can't use it out here.
- Hmmm... there's also a lot of antimatter around here. Antimatter is a form of matter in which most of the attributes of elementary particles are reversed.
- What's that? You want to know more about the big bang? Like maybe a timeline or something? Okay!
- Well, before it banged, the big bang was incredibly small. super dense speck of energy smaller than an atom. Then it blew up. We don't know why. But the universe started expanding, and the first force to emerge was gravity.
- The amount of gravity had to be super precise, because too much would make black holes and too little would send everything flying apart. The universe was expanding so fast they made a new unit of time for it: Planck Time. Basically, 1 second is equal to 1 billion billion billion billion billion planck times. Anyway, this stuff was expanding super fast, and the raw energy started turning into subatomic particles: the first matter of all time.
- At this point the universe is so hot that energy was converting into subatomic particles and back to energy, and as it cools, particles slow down and stop transforming. The universe is less than a second old at this point.
- The temperatures continued to cool, and the first elements were formed: Hydrogen, then Helium, then Lithium. The universe grew from microscopic to incomprehensibly huge in about 3 minutes.
- Now, before all of this was discovered, it was predicted by Einstein with his equation E=MC. Energy can be converted to matter, and vice versa. You know how a nuclear bomb is a small amount of matter converted into enormous energy? The big bang was the exact opposite.
- 380,000 years after the big bang, the universe started to become transparent. Before it was kind of milky. At 380,000 years old, the universe is trillions of kilometers across. 200 million years later, the first star appeared. 1 billion years later, the first galaxy. 9 billion, years later, our sun and solar system.
- The big bang is still expanding now. At 150 billion light years across, it may even be infinite. May be closed in on itself. Expansion definitely isn't slowing down. It's accelerating. Dark energy is pushing the world apart, killing the universe.
- Yep, galaxies are flying apart, and the furthest galaxies are flying the fastest. That's hubble's law. Galaxies moving apart in direct proportion to their distance apart.
- SO YES. THE WORLD IS ENDING. FAST. DARK ENERGY WILL BE THE DEATH OF US ALL.
- Hope you enjoyed the tour! I'll see you next time!!
