I'm gonna do some little deep dive threads into the Unruh effect and quantum field theory in general. I want to try convert the maths into words for max accessibility but also try avoid making it sound too vague and fanciful. Probably super easy to do. Anyway follow if this sounds cool to you! 🧪

Hopefully I don't get sued for reproducing this but it really is one of the most informative bits of text about quantum mechanics I have come across, from Carroll's 'An Introduction to General Relativity'. 🧪

"Without understanding the physics, mathematics does not answer your questions. Without understanding the mathematics, your physics theories will not work successfully either, is what we had to discover (and we keep forgetting time and again)." - ’t Hooft arxiv.org/pdf/1503.05007 🧪

@sonyacotton.bsky.social yay hello

"I think, therefore the cosmological constant must be very small." - Leonard Susskind in 'The Cosmic Landscape' summing up the Anthropic Principle 🧪

Is it socially acceptable to cold email a professor just to be like hey your work is inspiring and I wanted to be able to tell you that

This spacetime diagram morphing is a mathematical picture of viewing events in spacetime from different inertial frames of reference. Here we see how events that occur simultaneously in one inertial frame (on a line parallel to the x-axis) do not necessarily happen simultaneously in another 🧪

A nice easy one for Monday from J Hartle's Gravity 🧪

Particle physics is like, red flimflams emit floopydoops and become gigglepops, blue flimflams emit floopydoops and become red flimflams. Charlie Browns can emit other Charlie Browns and form Charlie chains. Chumbawambas are responsible for the expansion of the universe 🧪

What I do in public is nobody's business

In what sense does the Higgs field give particles mass? The standard model of particle physics is actually complete without Higgs, if all the particles moved at the speed of light. But only massless particles can move at light speed 🧪

Remember to take life 10⁻⁴⁴ seconds at a time 🧪

Nothing better than extremely hi-fi overproduced 'lo-fi' music

What is the relationship between these two equations of gravitational potential energy we learn in school? I'd tell but I have the flu 🧪

Trying to understand new maths concepts in science usually feels like it boils down to 'which numbers do I plug in where and how do I know if the numbers that come out are bigger or smaller than they should be'

Maybe she's born with it, maybe it's Alprazolam 🎶

Because time runs slower as gravity gets stronger, over a 100 year period a person living on the ground floor lives a few microseconds longer than someone on the top floor. 🧪⌛

Why can't I travel at just 1% lightspeed in this futuristic year of 2025? Then I could travel to the opposite side of the globe in less than 7 seconds. Seriously who wants to run the calculations? 🧪 It would make visiting my parents so much easier.

If this app wants to be legitimate it needs to find ways to reach more users in Africa, Asia, and South America to name a few regions. At the moment if feels more like a big whatsapp group for US Democrats

This common image is misleading because gravitational attraction is not caused by objects following a straight line in 3D space, but rather a straight line in 4D spacetime. The image doesn't represent time and therefore neglects time dilation's role in gravity. There's a better picture... 🧪

The Unruh effect is a prediction in quantum field theory that an accelerating thermometer in empty space without any other contribution to its temperature, will record a non-zero temperature, just from its acceleration, due to quantum vacuum fluctuations. 🧪

oh nice this is going to be another it's always sunny in philadelphia episode #superbowl

This is no exaggeration how I'm reading the linear algebra textbook 🧪

I stg if one more combination of vector spaces decides to result in another vector space I'm gonna lose it

'Think about them as carnivore animals (double dual vectors) eating herbivore animals (dual vectors) eating plants (vectors), while at the same time they both produce feces (real numbers).' Hm. Source ekamperi.github.io/mathematics/... 🧪

how do we all feel about trying to understand math notation that crams a lot of info into very compact notation and proceeds to write it like a language. we love it right?

why can't i mute images

I skeet so that my friends don't need to listen to all my bullshit

Can't sleep anyone wanna knock me unconscious

I haven't studied physics in a while and I forgot how much it twists your brain 🥨

Quantum Field Theory for particles doesn't include gravity. At higher and higher energy levels we can resolve smaller and smaller particles. But at the highest, Planckian, energy levels QFT breaks down. 🧪

It would be so great if people could reply to this with pictures of birds where they look angry :') #birds #birdsky #birding #birdphotography #wildlife

and so, the sauce thickens...🧐

An electron emits and absorbs around 10^19 virtual photons a second according to Susskind. I think the estimate is from multiplying the electron’s Compton frequency (~10^20 Hz) by the fine structure constant 1/137? 🧪

"...gluons have a strong propensity to stick together and form long chains: positive end to negative end, red to red, blue to blue and green to green." Sorry what, gluon spaghetti? 🧪

All these mass follow accounts are following about 3 times as many people as follow them. This is a depressingly high follow-back probability to me #followmethough #butiwontfollowyou

Hopefully Leonard Susskind will forgive me sharing this image from his The Black Hole War of a cat sitting beside a 2D holographic representation of itself. The scrambled bits of information of the hologram are meant to be Planck-sized. The cat does not know🧪

"Information is like clowns, and black holes are like clown cars." - Leonard Susskind, The Black Hole War 🧪⚫

"Whatever the size of the original black hole, this is the rule: Adding one bit of information will increase the area of the horizon of any black hole by one Planck unit of area, or one square Planck unit." - Leonard Susskind, The Black Hole War 🧪⚫
