This is Sadie Lou. Her astronaut mom just got back from orbiting the moon on Artemis II and Sadie is straight-up losing it with joy full-body wiggles, supersonic tail wags, and the happiest zoomies you’ve ever seen. Pure love exploding. best reunion doggo ever ❤️. Pls heart them
The math on this black hole should mass-humble every physicist who thinks we understand gravity.
M87's central black hole is 6.5 billion times the mass of our Sun. It's 38 billion kilometers across. It spins at 80% of the theoretical maximum speed allowed by physics. And it's firing a plasma beam at near light speed that stretches 5,000 light-years into space.
To put 5,000 light-years in perspective: if you started driving at highway speed when the Egyptian pyramids were built, you'd have covered roughly 0.0005 light-years by now. This beam covers ten million times that distance.
The plasma travels in a spiral along a coiled magnetic field. Hubble watched it for 13 years just to confirm the motion pattern. And the beam isn't just decorating empty space. Stars near its path explode twice as often as stars elsewhere in the galaxy. Nobody knows why. The lead researcher at Stanford said they don't understand the mechanism at all.
The black hole eats roughly 90 Earth masses of material per day. The energy output from that feeding process matches the power of the jet itself, somewhere between 10^33 and 10^37 joules per second. The upper end of that range is a number so large it has no human analogy.
Your brain runs on 20 watts. This thing outputs more energy per second than every star in the Milky Way combined. And we photographed it with a telescope in 2019.
BBC: Trump says you are the obstacle to peace.
ZELENSKYY: Ukraine is not an obstacle to peace. Russia attacked us. We need clear conditions to end the war and reliable security guarantees so that the war does not start again. We do not want to live through this hell again.
Republican Senator Thom Tillis to Kristi Noem:
“We're an exceptional nation, and one of the reasons we're exceptional is because we expect exceptional leadership, and you've demonstrated anything but that…And that is why I've called for your resignation.
