YOU’RE TELLING ME THE SUN, A G-TYPE MAIN SEQUENCE STAR, QUALIFIES AS A PLANET
AND PLUTO DOESN’T
OKAY LET’S SEE THE THREE IAU CRITERIA FOR A PLANET
IT IS IN ORBIT AROUND THE SUN. IS THE SUN IN ORBIT AROUND THE SUN? DIDN’T THINK SO.
IT ASSUMES HYDROSTATIC EQUILIBRIUM -basically a round shape. Okay. Got me there. One point to the sun.
IT ”CLEARS THE NEIGHBOURHOOD” AROUND ITS ORBIT. THAT MEANS IT GRAVITATIONALLY INTERACTS WITH SMALLER BODIES NEARBY. DOES THE SUN INTERACT WITH SMALLER BODIES NEARBY? NO. KNOW WHY? BECAUSE IT IS THE FREAKING SUN. ANYTHING CLOSE TO IT GETS INCINERATED.
SO THERE YOU HAVE IT FRIENDS. SUN GETS 1 OUT OF 3. WHILE PLUTO SIMPLY LOSES OUT IN THE THIRD CRITERION, BECAUSE IT SHARES ITS ORBITAL ”NEIGHBOURHOOD” WITH KUIPER BELT OBJECTS. PLUTO: 2 OUT OF 3.
AND YET SOMEHOW IN THE POSTER ABOVE, THE BLOODY FUCKING SUN IS A PLANET AND PLUTO IS NOT.

i didnt spend 40 minutes doing research for 24 notes

Biology’s cruel joke goes something like this: As a teenage body goes through puberty, its circadian rhythm essentially shifts three hours backward. Suddenly, going to bed at nine or ten o’clock at night isn’t just a drag, but close to a biological impossibility. Studies of teenagers around the globe have found that adolescent brains do not start releasing melatonin until around eleven o’clock at night and keep pumping out the hormone well past sunrise. Adults, meanwhile, have little-to-no melatonin in their bodies when they wake up. With all that melatonin surging through their bloodstream, teenagers who are forced to be awake before eight in the morning are often barely alert and want nothing more than to give in to their body’s demands and fall back asleep. Because of the shift in their circadian rhythm, asking a teenager to perform well in a classroom during the early morning is like asking him or her to fly across the country and instantly adjust to the new time zone — and then do the same thing every night, for four years.

This is why you have every right to be tired.
