I look up — many people feel small because they’re small and the Universe is big — but I feel big, because my atoms came from those stars. There’s a level of connectivity.

That’s really what you want in life, you want to feel connected, you want to feel relevant, you want to feel like a participant in the goings on of activities and events around you.

That’s precisely what we are, just by being alive…

What is the Big Rip?

"If dark energy is only a constant, than things like our Solar System, our galaxy, and even our local group of galaxies — consisting of the Milky Way, Andromeda, the Triangulum Galaxy, the Magellanic Clouds and a few dozen small, dwarf galaxies — will remain gravitationally bound together for trillions upon trillions of years into the future. But if dark energy is increasing, or getting stronger over time, then that acceleration rate will not only drive distant galaxies away from us, but will cause these structures to become gravitationally unbound as time goes on!"

Now that dark energy is firmly in place as the dominant source of energy in the Universe, the race is on to figure out exactly what its properties are, and what that will mean for the Universe’s fate. If it’s truly a cosmological constant, we’re in for a Big Freeze, as galaxies expand away from one another faster and faster, leaving only our gravitationally-bound local group behind. But if dark energy changes over time, we might yet see a Big Crunch or the most horrifying of all fates: a Big Rip, where galaxy-by-galaxy, star-by-star and eventually atom-by-atom, everything is torn apart!

Planets of Our Solar System

Our solar system officially has eight planets and one star: the Sun. The discovery of an object larger than Pluto in 2005 rekindled the debate over whether such objects, belonging to the Kuiper Belt – a collection of icy bodies located beyond Neptune – should be called planets. Pluto and other large members of the Kuiper Belt are now considered “dwarf planets.”

Most of my future children tag is cute brown children being fabulous and clearly belonging to me in spirit, but I’m making an exception for this tweet because if I don’t raise my kids to give that exact same response, then I have failed as a parent.

Who is this woman and can I send her a thank-you gift basket and a Black Parenting Award?  This is why it is imperative that we teach our children real history outside of textbooks constructed by, written for, and approved by white men whose re-telling of history conveniently glosses over atrocities and minimizes suffering.

"bold new idea"

I want to go to that school and set fire to every history book in the building.

Woooooowww the fucking nerve makes me want to home school my kids dead ass. I went to a Christian all white private school the majority of my life and I had to go through this bullshit and I never want my kids to deal with it. My kid would get suspended like everyday debating with the teachers lol

that child is going places. parenting done right and education failing again

This is a problem not just with lung capacity measurements but with health inequality more generally. There’s vastly, vastly, vastly more research on genomics than on the social determinants of health. Part of the problem is the infrastructure of science. What kinds of questions are considered scientific?”
