One hundred years ago this month, Albert Einstein published his theory of general relativity (GR), one of the most important scientific achievements in the last century.
A key result of Einstein’s theory is that matter warps space-time, and thus a massive object can cause an observable bending of light from a background object. The first success of the theory was the observation, during a solar eclipse, that light from a distant background star was deflected by the predicted amount as it passed near the sun.
When Einstein developed the general theory of relativity, he was trying to improve our understanding of how the universe works. At the time, Newtonian gravity was more than sufficient for any practical gravity calculations. However, as often happens in physics, general relativity has applications that would not have been foreseen by Einstein or his contemporaries.
How many of us have used a smartphone to get directions? Or to tag our location on social media? Or to find a recommendation for a nearby restaurant? These activities depend on GPS. GPS uses radio signals from a network of satellites orbiting Earth at an altitude of 20,000 km to pinpoint the location of a GPS receiver. The accuracy of GPS positioning depends on precision in time measurements of billionths of a second. To achieve such timing precision, however, relativity must be taken into account.
Our Gravity Probe B (GP-B) mission has confirmed two key predictions derived from Albert Einstein’s general theory of relativity, which the spacecraft was designed to test. The experiment, launched in 2004, and measured the warping of space and time around a gravitational body, and frame-dragging, the amount a spinning object pulls space and time with it as it rotates.
Scientists continue to look for cracks in the theory, testing general relativity predictions using laboratory experiments and astronomical observations. For the past century, Einstein’s theory of gravity has passed every hurdle.

Stephen Hawking was given 2 years to live in 1964.
He multiplied that by 27.
Rest in peace you magnificently intelligent man.
“Now you could love a snowflake just because it’s pretty, but it doesn’t take away from its beauty that it was sculpted by chance and physics. To me, that adds to the beauty. I have to say, this whole “we are unique snowflakes” thing is pretty cheesy. It might be the most overused metaphor in the history of metaphors, so let me give you a new one: Snowflakes are symmetrical, but they’re not perfect. They’re ordered, but they’re created in disorder, every random branch re-tells their history, that singular journey that they took to get here, and most of all they’re fleeting and temporary. Even if sometimes they don’t look so unique on the outside, if we look within, we can see that they’re truly unique after all. Stay curious.”

MIDTERMS ARE FINALLY OVER!!! 🤓 i’ve been studying for philosophy and biology the last two days! here is a mind map for philosophy and flashcards for biology 🌎☄💫 now i’m just hoping and praying i get good results back for all my midterms 😫

however bad life may seem, there is always something you can do and succeed at.
"Now, I am become Death, the destroyer of worlds.“
Robert Oppenheimer did not say this when he witnessed the culmination of the Trinity Project but instead said in a television interview that he was reminded at the time of the line from the ancient scripture. But of course it is much better to imagine him whispering it in quiet awe.
