Why the Universe Contains Something Rather Than Nothing βœ¨πŸ€·πŸ»β€β™‚️

Who would have thought that answer to the Ultimate Question of Life, the Universe, and Everything lies in giant tank of water 3000 feet under Japan? And the answer is not 42.

Scientists on Wednesday announced that they were perhaps one step closer to understanding why the universe contains something rather than nothing.

πŸ‘‰ Why the Big Bang Produced Something Rather Than Nothing (New York Times)

This story is not just about speculation or a cool idea. This story is about scientists working at an underground laboratory in Japan, trying to catch neutrinos, sent from 180 miles away. This experiment helps them understand why matter won over anti-matter at the beginning of time, and thus why the universe is full of, well, stuff (this was apparently not a foregone conclusion πŸ€·πŸ»β€β™‚οΈ).

As a result, a universe that started out with a clean balance sheet β€” equal amounts of matter and antimatter β€” wound up with an excess of matter: stars, black holes, oceans and us.

This article is full of mind-blowing quotes.

These ghostly subatomic particles stream from the Big Bang, the sun, exploding stars and other cosmic catastrophes, flooding the universe and slipping through walls and our bodies by the billions every second, like moonlight through a screen door.

I love the balanced excitement / skepticism of the scientists, calling this news β€œundeniably exciting.”

There are further plans to send neutrinos from a lab in Illinois 800 miles underground to a giant underground detector at an old gold mine in South Dakota. πŸ‡ΊπŸ‡Έ

The Dyson Sphere Theory

Okay, I’m not huge on wild conspiracy theories. But I like that some scientists think it is at least plausible that highly advanced aliens are building  megastructures around stars to capture their energy like a battery. 🀯 The cool thing is there would actually be a good reason for aliens to do this if they were capable enough. πŸŒŸπŸ”‹

I’m not saying I believe it, but I love that this is a theoretical possibility. And it’s influencing SETI.

πŸ‘‰ Missing stars could point to alien civilizations, scientists say

The idea here is that a very advanced alien civilization may be able to construct a hypothetical megastructure called a Dyson sphere that completely encompasses a star in order to capture a large portion of its energy. Think of it as converting a star into a gargantuan battery.

Roadmap to Alpha Centauri

With the Voyager space sailing beyond out solar system, this article looks at some ways we could send people to Alpha Centauri.

πŸ‘‰ Roadmap to Alpha Centauri

This article is a complete mindmelt 🀯: ion drives, solar sails, nuclear rockets,  foraging for dark matter.

I don’t really understand this stuff, but I do like the idea that people could potentially fly around the universe and find a new home. Especially considering the black holes out there.
