This One Thought Experiment Shows Why Special Relativity Isn’t The Full Story
“In Einstein’s initial formulation of General Relativity way back in 1916, he mentioned the gravitational redshift (and blueshift) of light as a necessary consequence of his new theory, and the third classical test, after the precession of Mercury’s perihelion (already known at the time) and the deflection of starlight by a gravitational source (discovered during a total solar eclipse in 1919).
Although a thought experiment is an extremely powerful tool, practical experiments didn’t catch up until 1959, where the Pound-Rebka experiment finally measured a gravitational redshift/blueshift directly. Yet just by invoking the idea that energy must be conserved, and a basic understanding of particle physics and gravitational fields, we can learn that light must change its frequency in a gravitational field.”
If a photon flies through space towards Earth, it must gain energy and become bluer in nature as it approaches Earth’s surface. This idea, of a gravitational redshift or blueshift, dictates how a photon must change in energy in the presence of a gravitational field. Yet this effect, which only exists in General Relativity, could have been predicted as soon as special relativity was discovered by one simple thought experiment: to consider a particle-antiparticle pair dropped from high above the surface of the Earth, but to let the annihilation occur at varying locations.
If you considered that, you’d immediately realize how special relativity was insufficient for describing our Universe! Come learn how to reason it out for yourself today!

So there's this website that gives you every song that played in an episode (no matter how short a time it was playing)
It even gives you a description of the scene so you know when/where you heard it
Look!

you guys probably already knew about this but yeahh. I’m just really excited because I was wondering what that song was when Mickey walks into the club
But it’s here for future references

IN THE BEGINNING
As the sun light climbs its way over the horizon to wash the landscape, It begins to peer into the windows of 56 sunnybrooke lane. It stirs the inhabitants slowly to wake as its warmth Hovers above, the motivation to open ones eyes to see the good morning rays. Michal Woodforest rubs the crust from the sides of his eyes and lays in his bed for a moment to smirk to himself. “18” he said to himself. As he sits up and looks out his window; he sees the the dew resting atop the blades of grass, shimmering as if set ablaze by the sun. Only to be disturbed by the slight breeze from the east carrying with it the mountain smells of pine and redwood wafting through his window. cracked just enough to hear the garbage truck coming up the street. But for as slowly as the day creeped into his house the thought creeped into his mind “did I take out the garbage to the street!” He leaps from his bed tossing aside anything that resided on his bed with him. A game boy tumbled to the ground. He takes two steps toward he bedroom door and with unreasonable amount of care he turns the handle slowly and pulls the door downwards as to avoid the ungodly squeaking from the hinges that haven’t been oiled in years. As the door opened he looked down the hallway littered with holes, as if a gopher lived inside the dry wall of the house. Michael poked his head out of the door way to see if his father was awaked by the noize. michaels luck seemed to have no bounds today. he wasn’t awake witch gave him enough time to grab the trash from the little kitchen can and make it to the street before the trash truck drove passed his house. As Michael brought in the now empty trash can he wondered. “How is dad still asleep?” As it was now 9:30 and michaels father doesn’t sleep in past 9 a.m. unless he was drinking. But all the better for Michael. No angry father to ruin his first day as a free man. he was finally free from the shackles that were his town. The over crowded halls, worthless teachers, and all the mindlessness of everyone around him. As he started makeing breakfast he was sure his hungover father would wake up stumbling down the hall to the kitchen to threaten him for some eggs and toast. But as the eggs were cooked and the bread toasted the fragrance of the food danced down the hall and snuck into each room but was not received by anyone. There was no stirring no stumbling no moans or groans no yelling. Only the sound of the eggs cooking in the skillet.
“I haven’t had eggs and toast with out being bothered since mom was still with dad.” And as that thought rolled into his mind like a wave starting to reach the crest and then comes the crash. The door to his fathers room swings open so hard that the rusted hinges scream out all at once to be accompanied by the crash of the door into the already made hole where the door handle meets the wall. The man slowly walks to the kitchen only to glare at the young man. As he staired the air around Michael became stiff as the smell of cigarette pours out of his fathers room. like a bow of a boat cuts over the water so did his fathers voice ride atop the stench of alcohol and smoke. “Did you make any food for dear old dad?” He said in the throaty voice almost so inebriated that his speech a garble of sounds. But as Michael expected this he responded quietly and politely yet quick and to the point. “Of course” Michael responded. “Did you take out the trash before the truck came by” again Michael responds with “of course” and as the words came out of his mouth his dads fist went through the plate of eggs made for him. And with a billowing voice that could be heard echoing outside the father screamed “don’t get smart with me!” As he slid Michaels plate to himself and ate what was left on it only to throw that plate as well. “I have to go to work and I won’t be back for a few days make sure when I come home it’s not a pig stie in here or I’ll throw you out.” Michael’s father had been useing the same lines and same drink for a while so Michael knew once he left he had until Monday to get everything out and leave his dad behind for ever. And once the words his father said reached his ears he couldn’t help but smile ever so slightly at the thought. “I’ll be free soon.” But just as quickly as the thought came the hand did too to wake him from his happiness like the sun woke him from his sleep. As Michael opened his eyes he heard the red Ford F-150 that his father had destroyed over the years the bed destroyed from moving rubble. The paint scraped to bare metal mixed with rust the hood held down by bailing wire after the first dui. But as the tires spun on the gravel drive way just like the truck his father was going away and as Michael lay on the ground he begin to let himself smile and that smile creeped across his face like the tide when it comes in. Slowly but so sneeky you don’t even notice. the smile sat on his face like the paint on the inside of the sistine chapel. he sat up and stayed their on that kitchen floor he had scrubbed for years and looked at himself in the reflection of the oven door and began to laugh and Michael laughed so hard he began to cry and once he had finished laughing and no sooner then the first tear hit his jaw he picked up the pieces of plate off the floor and cleaned the egg off his face and went to his room to sleep and not be bothered ever again. For tonight he leaves forever.
