@gpatterson828 Most people don't realize how much their phones, GPS, and even some internet depend on satellites we put up there. Space exploration isn't just rockets—it's the backbone of tech you use daily.

@FoxNews Like a CEO once said at a company awards ceremony, we recognize effort, we reward results.
Mr. Bonta, you have no results.

@DavidJHarrisJr This is typical politics these days!
Dem's will claim she's the most beautiful and bring happiness to all of humanity.
Republicans will claim she's so ugly, she's a threat to the safety and well being to all humanity.
Always the mirror opposite, not one bit of it is reality.

@chefsevenn My protein of choice, got to love protein!
Keep it lean, it's all good!

@SoveyX Is that even edible? Looks like the stuff I made for a grade school volcano project!

@shouq_al90149 By what metric, complacency?
Biden was feckless, period.

@wakeupusa No, he's angry, and oblivious to the rest of the world.

@Pechin_D @elonmusk @boringcompany Bouth trains and pumps are useful tools and there are even pumps inside of trains already mind-blowing I know. In high-speed trains they are used to pressurize the cabins 🤯. But a rotary system has nothing to do with running a mass transite system in a pressure chamber.

The @BoringCompany could build a Hyperloop tunnel from downtown SF to downtown LA for <5% of this cost and it would be a technological marvel exceeding any high speed rail on Earth

If you gave away $126 billion to subsidize free flights between LA and San Francisco at current demand levels, you could fund roughly 150 to 200 years of travel before the money runs out.

@Darkdarling00 Never taped radio, always album to cassette or cassette to cassette, everything else, check.

@_josephine0_ That's the beauty of the US, you can find it all here!

@RockNRoLL_85 By charts and sales, Elton John was the biggest — multiple No. 1 albums and massive hits.
But for pure rock band, (with the big three out), I’d go with The Who. Still, too many legends owned the decade — Queen, Sabbath, Skynyrd, Steely Dan, etc. Impossible to pick just one.

@CordasFilip @elonmusk @boringcompany Don't worry, you're a tool, who can't see both technologies used in tandem for a different application.
And both have potential benefits, but go ahead, be like the people who said the sound barrier wouldn't be broken. Now go away, you've proven yourself to be ignorant.

@Pechin_D @elonmusk @boringcompany please don't consult me anything I don't do good with morons. The reason I pointed that out because you said something stupid, so you are welcomed. But please explain to me what pumps have to do with trains?

Wow, groundbreaking insight from the guy who just discovered vacuum has ranges. Next you'll tell me water has a vapor pressure and high-vac isn't always required for low-resistance motion. Thanks for the lecture, professor — I'll be sure to consult you before my next thin-film deposition patent. 😏!
English

@Pechin_D @elonmusk @boringcompany you don't know that's the problem for example 'vacuum' is not 'empty' that's a perfect vacuum a vacuum is on a scale from low to extremely high and I can't emphasize this enough has nothing to with meglev trains

@PollSter_Mike1 My first thought was Harry Nilsson's cover of Badfinger.
I can't live, if living is without you. Read right over the U2 part.

@CordasFilip @elonmusk @boringcompany Again, He who knows not and knows he knows not is a fool.
But, you wouldn't know Confucius either, now would you.
English

@Pechin_D @elonmusk @boringcompany There are perpetual motion machine patents this might impress people that don't know what a patient is but really this means nothing. And again, you are just using random words you heard and putting them together
