Today marks 25 years since NASA’s Voyager 1 spacecraft saw Earth as “a pale blue dot.”
“Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every “superstar,” every “supreme leader,” every saint and sinner in the history of our species lived there - on a mote of dust suspended in a sunbeam.” -Carl Sagan
Been getting a lot of asks about “NASA finding a parallel universe” or whatever and let me break it down.
It’s 90% sensationalism. ANITA, a detector in Antarctica has recently picked up some strange signals. The signals indicate that a very high energy particle (the neutrino) had passed through the earth without interacting with anything, something unexpected of a high energy particle.
So, here come the weird ideas. Scientists try to come up with ways of modifying our understanding of physics to make these detections more plausible. SOME of these require bizarre beyond the standard model ideas, like the one in the news. However there are much more likely answers, such as a common function of how physics normally works (won’t go into details here, but here’s a paper on it https://arxiv.org/abs/2001.01737) or simply a systematic explanation, like the signals bouncing off weird features in the ice and distorting the signal. Here’s another article: https://link.aps.org/doi/10.1103/PhysRevLett.123.091102
The victims of the 1986 Challenger Shuttle explosion likely did not die on initial failure of the rocket, but instead were probably alive and conscious until their fuselage crashed into the ocean some time later. Six astronauts and one civilian schoolteacher died.
The failure was due to malfunctioning O-Rings, a known problem to both NASA and the contractor hired to build the shuttle. Several NASA engineers warned against the launch and were concerned about the integrity of said O-Rings. Several chief engineers, most notably Roger Boisjoly, pleaded for the launch to be rescheduled, but was ignored by the administration.
“I was looking at the moon and I accidentally captured footage of a once in a lifetime lunar mission that’s mapping the surface of the moon a quarter of a million miles away…” Now THAT’S COOL!
Space mom I REALLY want to go to the moon. We’ve been talking about NASA and how it started and all the missions they did in my AP physics class and it just really really intrigues me. I want to be someone who walks on the moon. Do you think NASA will ever send someone to the moon again? Do you think it’s possible I could be one of the people who go to the moon?
Anything’s possible! If not with NASA then maybe with a private company.

the jenkinverse is a super cool collection of stories (you can find them on reddit) about humans that find themselves amongst aliens, but because the Earth is what is considered a Death World, humans are a lot stronger and faster than aliens. Humans are, to put it simply, the monsters aliens had never even thought existed. (aka humans are space orcs, the second (?) story, Humans don't make good pets, is the best I think. They are all very good)
Ooooooo
