This Is What the Birth of the Universe Sounded Like | Mark Whittle | TED

What sound came after the Big Bang? Astronomer Mark Whittle takes us back to the infant cosmos, where massive sound waves pulsed through primordial gas in a pattern that’s still traceable across the galaxy today. Working with sound artist Ander Mikalson and composer Caroline Shaw, he turns those ancient tones into a glorious, awe-inspiring choral…

A vacuum
Not like a Dyson
It would have been a Hoover back then

So cool that they had a choir perform this sound. If the universe were sentient, I’m sure it would be a startling and give it a fond nostalgia.

I definitely didn’t have manifesting figured out. I kept trying different techniques, getting nowhere and wondering what I was doing wrong. Amara Lorne arche type quiz helped me understand that I was using methods that simply didn’t match me. Nothing magically changed overnight, but it finally gave me some direction. It’s free, so you might as well try it.

Sorry but that makes no sense. The Big Bang couldn‘t produce a sound because there was no atmosphere, no gases of any kind. You can take anything that produces some back and forth movement and feed it into an amplifier and speaker.

Building flying taxis takes billions of dollars. So instead of relying on traditional venture rounds, Archer Aviation went public just a few years after it was founded.

In this episode of Build Mode, host Isabelle Johannesen sits down with Adam Goldstein, founder and CEO of Archer Aviation, to talk about the unconventional fundraising strategy behind building one of the most capital-intensive startups around.

Archer is building electric vertical takeoff and landing aircraft, or eVTOLs, designed to turn trips that can take 90 minutes by car into flights of 10 or 15 minutes. The company is developing the technology for both commercial air taxis and defense applications and has been selected as the exclusive air taxi provider for the 2028 Los Angeles Olympics.

But developing and certifying an entirely new category of aircraft requires enormous amounts of capital. Adam explains why he realized early on that raising $50 million or $100 million at a time wouldn’t be enough and why he decided to take Archer public when the company had fewer than 100 employees. Since then, Archer has raised nearly $4 billion.

Adam breaks down how he prepared Archer to take advantage of the public markets, why timing matters so much when pursuing an IPO, and how retail investors and online communities have changed the equation for companies building ambitious hardware. He also explains why he thinks the window for earlier-stage companies to access public markets may be opening again.
