If the Moon vanished, Earth would still have day and night, but tides would weaken considerably, affecting coastal ecosystems and fishing and aquaculture livelihoods. The Moon helps keep Earth's axial tilt of about 23.5 degrees relatively stable, so over geological timescales the tilt could vary more, making climate and seasons harder to predict, though the extent depends on the dynamics of the wider Solar System. Many marine species that rely on lunar cycles for reproduction and feeding could also be disrupted. The article calls this a thought experiment, noting that current physics gives no natural way for the Moon to disappear without a cause, and that humans would likely survive in the short term even as the familiar world changes.

- The Most Plausible Mass Time-Travel Event in the World: 50,000 People Vanished Suddenly and Still Can't Be Explained!
In 522 BC, a Persian army of 50,000 soldiers under Cambyses II marched into the Egyptian desert toward Ammon, but vanished after stopping to rest in an oasis town. No bodies, weapons or armor were found, and the article argues that even a sandstorm could not explain such a complete disappearance. Two Italian historians spent eight years searching the area without results. The article notes that the mystery remains unsolved, with some suggesting a mass time-travel event.

- Jeff Bezos Says We Went To The Moon In 1969, But If It Was So Easy Then Why Is It So Hard Now? ‘We Spent 3% of GDP…It Was Very Expensive’
Jeff Bezos, founder of Amazon and Blue Origin, told Fox News that the 1969 Moon landing cost almost 3% of GDP, which helps explain why returning has been hard. He wants the next phase to be a lower-cost, sustainable lunar base rather than brief missions, and describes the Moon as a steppingstone about a three-day journey from Earth with resources for solar cells and rocket propellant. Bezos said he has personally invested $28 billion in Blue Origin since founding it in 2000, and the company recently raised $10 billion from outside investors for the first time. He expects Blue Origin to eventually have an IPO, though probably a few years later. The article also notes SpaceX completed its IPO in June.

- Bitcoin ETFs just saw their biggest day in a month thanks entirely to BlackRock
U.S. spot bitcoin ETFs took in $526.6 million on Monday, the largest daily net inflow in nearly a month, driven entirely by BlackRock's iShares Bitcoin Trust (IBIT), which pulled in $665.2 million, its biggest daily inflow since Oct. 7 last year, according to SoSoValue data. Fidelity's FBTC lost $83.6 million and Grayscale's GBTC shed $54.9 million, while the remaining funds recorded no net flows. The inflow more than erased last week's $228.5 million of withdrawals, but funds remain about $90.5 million in net outflows for October, according to CoinDesk calculations. Ether funds moved the opposite way, losing $103.3 million in their fourth consecutive session of outflows, with BlackRock's ETHA accounting for $95.4 million of that.
- A Big4 bank cut deposit rates in the morning, then raised them again in the afternoon
VietinBank cut its deposit rates for terms of 6 months and longer on the morning of Oct. 20, then restored them to pre-adjustment levels by the afternoon. Its afternoon rate board showed 3.5% per year for 6 to under 12 months, 5.9% for 12 to under 24 months and 6% for 24 months and longer, versus 3%, 5.4% and 5.5% in the morning. Rates for terms under 6 months stayed unchanged, including 2.1% for 1 to under 3 months and 2.4% for 3 to under 6 months. The move came as banks followed the State Bank of Vietnam's guidance to cut deposit rates by at least 0.5 percentage points for terms of 6 months and longer, and Vietcombank and Agribank were among those reducing rates.
- IVV vs. SPY: Which S&P 500 ETF Is the Better Buy for Long-Term Investors?
The article compares two ETFs that track the S&P 500, iShares Core S&P 500 ETF (IVV) and State Street SPDR S&P 500 ETF (SPY), which have nearly identical holdings. The main difference is the expense ratio: IVV charges 0.03% a year, one-third of SPY's 0.09%, and its distribution yield is about 1.1% versus 1% for SPY. SPY's high liquidity remains valuable for active traders. The article concludes that IVV is the better choice for long-term investors, since lower costs can compound over time.
- Warren Buffett Is Issuing a Stark Warning About the Stock Market. Here's What History Says Comes Next.
Warren Buffett has warned that investors are taking on too much risk, likening the market to 'a church with a casino attached' and saying people have never been in a more gambling mood. The article points to the S&P 500 Shiller CAPE Ratio, which has stayed above 40 since May of this year; historically, the only other time it held above that level for months was during the dot-com bubble, when it peaked around 44 before the bear market began in March 2000. The article notes that 40 is not an automatic trigger for a downturn, and no metric can predict timing. It suggests investors focus on quality stocks with solid fundamentals and be ready to hold them for at least a few years.
- Early Uber Investor Jason Calacanis Predicts Waymo Could Buy Lucid Or Rivian — Calls Its Chinese-Car Optics ‘Really Bad’
Early Uber investor Jason Calacanis predicts Waymo will buy Lucid Group (LCID) or Rivian Automotive (RIVN), arguing that its reliance on Chinese-made Zeekr vehicles creates cost and reputational problems. He says the arrangement is technically not illegal today, but Waymo would need to pay a tariff of over 100%, and it has drawn national-security concerns on Capitol Hill. According to Semafor, Waymo aims to grow its fleet from about 4,000 vehicles to 8,000 by the end of 2026 and 20,000 by the end of 2027, after closing a $5 billion term loan and a $16 billion equity raise this year. Uber has committed to buying at least 35,000 Lucid vehicles, while its Rivian deal starts with 10,000 autonomous R2 SUVs, with rides expected to begin in 2028. Calacanis, who recently bought small stakes in Lucid, Rivian, WeRide (WRD) and Pony.ai (PONY), expects consolidation in the autonomous-driving sector within 24 months.
