I love science because science! I love talking to people about science even if they didn't want to talk about science because science is so sciency.

Octopuses have three hearts: two just to pump blood through the gills and one more to circulate it to the organs. The circulating heart stops beating while an octopus swims, as swimming puts a lot of pressure on their bodies.

Before unleashing their infamous stink bomb, skunks stomp their feet, hiss, and sometimes even do a handstand to warn predators. So, if you see an acrobatic skunk - run.

Octopuses (and some other cephalopods) can rewrite their RNA on the fly to adapt to changes in their environment. This allows them to tweak how their neurons function, helping them survive in different temperatures or even enhance their intelligence.

Lake Vostok, a subglacial lake buried under 2.5 miles (4 km) of Antarctic ice, has been completely cut off from sunlight, the atmosphere, and the rest of Earth for millions of years - and is teeming with life.

WASP-76b, an ultra-hot Jupiter exoplanet about 640 light-years away. On the day side, temperatures soar past 2,400°C (4,350°F) - hot enough to vaporize iron into gas. WASP-76b is also tidally locked. The hot side vaporizes iron, which condenses into liquid metal and falls as molten iron rain.

A massive cloud of gas located near the center of the Milky Way galaxy, which contains a significant amount of ethanol (ethyl alcohol), alongside other complex molecules, is essentially a giant cloud of "space alcohol." This cloud is often described as smelling like rum due to the presence of esters

PSR J1748-2446ad is the fastest known spinning pulsar. At about 20 kilometers (12 miles) across, it spins over 700 times a second - at the equator that’s 24% the speed of light.

The One-Electron Universe Theory is an idea proposed by physicist John Archibald Wheeler
in a phone call to Richard Feynman in 1940. It suggests that every electron in the universe is actually the same single electron, traveling back and forth through time #science #sciencefacts #oneelectronuniverse

On September 3, 2002, astronomers discovered an asteroid with an unusual orbit around Earth. Further analysis of its trajectory and spectrographic evidence—specifically, the presence of titanium dioxide used in Apollo missions—revealed that it was actually the third stage of the Apollo 12 rocket.

Surfing bathymetry refers to the underwater topography that shapes how waves break, including reefs, sandbars, and underwater canyons. The ideal bathymetry funnels wave energy toward shallow areas in a way that creates clean, rideable waves.

A humorous concept among the scientific community, often referred to as 'The Pizza Radius' or the 'Thermonuclear Culinary Zone,' suggests that for every nuclear explosion, there exists a precise mathematical distance where the heat flux would be just right to perfectly cook a frozen pizza.

Spectralon is considered one of the whitest and most reflective materials known - reflecting over 99% of light. However, it’s not a pigment in the traditional sense - it's a highly diffuse reflective material made from polytetrafluoroethylene (PTFE, the same polymer as Teflon).

Galagos, also known as bush babies, have large, forward-facing eyes that are fixed in their sockets, meaning they can't rotate their eyeballs. To compensate, they have extremely flexible necks that allow them to turn their heads almost 180 degrees.

Sperm whales have two nostrils, but unlike most animals, they are asymmetrically positioned. The left nostril is visible on the outside and forms the single blowhole used for breathing. The right nostril is hidden inside the whales massive head and is actually part of its complex echolocation system

90% of the atoms in our bodies were forged in stars - elements like carbon, oxygen, nitrogen, and iron. The remaining 10% comes from the Big Bang - the universe's first moments which created the lightest elements, hydrogen and helium.
