Hey @ElonMusk you once said #Bitcoin could return to Tesla if 50% of its energy came from renewables. Well, $BTC is now 56.76% sustainable, outperforming every other major industry. Will Tesla embrace Bitcoin again? The world is watching. 🌍⚡

@DrKnowItAll16 @grok Great idea thanks

All right, @grok's image style editing is too much fun. Here's a thread with the following picture redone in a number of classic art styles. The last one is my favorite (Grok had to work hard for that one!).

Yeah!

Elon calling the commander of the International Space Station "retarded" was not on my bingo card...

Let's do some math on how big a spacecraft would be needed to divert 2024 YR4 in 2028 so it would miss in 2032 - according to @astroEdLu the velocity uncertainty is 0.35m/s with a 2.3% chance of impact. That means there's roughly a 0.008m/s range in velocities which lead to an impact in 2032, change it by more than this much and it misses. That's less than a cm/second. But on a 2028 intercept we'd have half the time, so, double that to 0.016m/s, let's say 0.02m/s just to add some margin. When 2024YR4 flies past Earth at the closest point it's moving at 13km/sec, let's use that as our impactor velocity. Slow it down and it arrives early in 2032 so that it passes through the encounter before the Earth arrives there. Dividing 0.02 by 13,000 gets 1.54E-6 the required mass ratio between impactor and asteroid, that's assuming no beta value enhancement. Estimates of the asteroid mass range from 25,000t up to over a million. So our spacecraft needs to be anything from 40kg to 1,600kg on impact. These are trivially possible to send out to 0.05 for a 2028 intercept, the hardest part is the high precision terminal guidance, hitting it straight on would be on the dark side of the asteroid. If we come from a different angle then cosine losses increase mass requirement. But then we need to make sure we don't break the asteroid by hitting it too hard, which makes my recent video at the Ames Vertical Gun Range relevant!

I need a @grok feature that synthesizes the last 6–12 hours of content from the people I follow into a 30-minute podcast I can listen to on my way to work. cc @xai @TheGregYang

@elonmusk @xai Please a new version of 🚀👽 Kerbal Space Program #KSP

Too many game studios that are owned by massive corporations. @xAI is going to start an AI game studio to make games great again!

@j_d_noone @USCRPL This story is heartbreaking.. unbelievable! Thanks for sharing. In the rocketry community you are a great example for everyone who want push skyward the limits and your video SPACE or NOTHING is a must! youtube.com/watch?v=72VkAo…

Shameful behavior. I met Neil in 2013 when running USC's Rocket Propulsion Lab @USCRPL. We were excited to have him come by, show him our work, and tell him our goal of flying the first student-built rocket to space. While there we told him about our goals and his response was "Why fly a rocket to space? You're already in space! The Earth moves through space. Every rocket already flies to space because it starts in space!" We found it funny at the time. But in the 11 years since it's clear he will say anything to sound scientific, create clickbait, at the risk of demotivating the next generation of scientists and engineers. USCRPL has since flown to space multiple times, broken world records, not just student world records. Couldn't be prouder of the students there. abc7.com/post/usc-rocke… Hundreds of graduates from the group had their careers accelerated, easily getting jobs across the entire space industry. Countless startup founders have came from the group over 20 years, thousands of jobs. Shameful.
