Really? I don’t think you can smell a vacuum like space and live to tell about it.

I’m no scientist but if you are traveling AT the speed of light, you shouldn’t be able to age. Time dilation at c would be infinite and thus no time will have passed for you regardless of how much time is spent traveling at the speed of light.

Is my reasoning borked?

He starts of by being wrong. Space is not hot or cold. Your body has nothing to conduct thermal exchange with in space.

Learn What VCs Actually Want, From a Founder Who’s Raised $1B l Build Mode

Investors want founders who understand the financial reality of their business.

In this episode of Build Mode, host Isabelle Johannesen sits down with Sasha Orloff, founder and CEO of Puzzle and Startup Battlefield alum, to talk about what he’s learned from building companies that have raised more than $1 billion collectively.

Sasha breaks down what investors look for during fundraising, which financial metrics founders should know by heart, and why VCs don’t expect your startup to be perfect—they expect you to understand its reality. He also shares how he nearly lost a term sheet because his data room wasn’t ready, how fundraising diligence changes as a startup grows, and why getting your financial house in order can help founders raise with more confidence and leverage.

They get into:
– What raising more than $1 billion across multiple companies taught Sasha about fundraising
– Why investors value founders who have a strong grasp of their company’s financial reality
– The financial metrics founders should know before pitching VCs
How investor expectations change from pre-seed and seed through Series A, B, and beyond
– Why revenue growth and the quality of that revenue are critical fundraising metrics
– How runway, margins, sales efficiency, and profitability factor into investor decisions
– Why waiting until you’re running out of cash can hurt your fundraising leverage
– How Sasha nearly lost a term sheet because his data room wasn’t ready
– Why financial organization and compliance can influence investor confidence and startup valuations
– What founders should have prepared for the due diligence process
– Why VCs don’t expect perfection—and why being honest about what isn’t working can make for a stronger pitch
– How Sasha’s own fundraising and finance frustrations ultimately led him to build Puzzle
– How AI could change the way startups manage accounting and understand their financial health

How Satellites and AI Can Protect the Planet | Robbie Schingler | TED

Published

August 20, 2026

CYBER TECH TV

Space technologist Robbie Schingler cofounded a satellite company that images the whole planet every day, making visible changes on Earth. He shows how pairing that data with AI creates a “planetary intelligence” we can use to spot emerging threats we might not have seen otherwise. Now he asks: Can we close the gap between seeing a crisis coming and actually stopping it? (Followed by a note from TED guest curators Divya Siddarth and Audrey Tang) (Recorded at TED2026 on April 14, 2026)
