You would absolutely be electrocuted, and your waterproof shoes wouldn’t save you. Here’s why: When lightning strikes a tree, it doesn’t politely follow a single path to ground. The electrical current spreads through the tree in multiple directions, and since you’re physically touching the tree with your hand, you become part of the electrical circuit. Your shoes are irrelevant in this scenario because the current doesn’t need to go through your feet to the ground - it can travel from the tree, through your hand, through your body, and then jump from any part of you (your other hand, your head, your torso) directly to the ground through the air. Lightning already demonstrated it can jump through air to reach the tree in the first place, so a few feet from your body to the ground is trivial. Even if we imagine impossibly perfect insulation on your shoes, the current would simply arc around them. Think of it this way: lightning just traveled potentially miles through air to hit the tree - the air gap around your shoes is nothing by comparison. This is exactly why safety guidelines warn never to take shelter under trees during thunderstorms, and why you should never touch anything connected to a lightning-struck object. The tree effectively becomes a massive electrical conductor for those brief moments, and any contact with it puts you directly in the path of potentially lethal current. Your best bet in a thunderstorm is to get inside a building or a car (which acts as a Faraday cage), not under a tree.

The acquire-vs-innovate question reveals a fundamental tension in how tech markets evolve. Both strategies serve different purposes, but the balance matters enormously for innovation and competition. The case for acquisitions: Companies like Google acquiring YouTube or Facebook buying Instagram often argue they can scale promising technologies faster than startups could alone. Sometimes this works - YouTube might never have reached its current scale without Google’s infrastructure and resources. Acquisitions can also bring in talent and combine complementary technologies in ways that pure internal R&D might miss. The case for innovation: Internal innovation tends to produce more genuinely novel breakthroughs since companies aren’t just buying existing solutions. It also maintains more competitive pressure in markets, preventing any single player from simply purchasing their way to dominance. The WhatsApp counterfactual is fascinating. Without Facebook’s acquisition, WhatsApp might have remained a focused messaging app, potentially with a sustainable subscription model rather than ad-driven. We might have seen more messaging innovation as WhatsApp, Telegram, Signal, and others competed more directly. Facebook might have had to actually innovate in messaging rather than just buying the leading competitor. The Twitter/Bluesky parallel is playing out right now. Bluesky emerged partly because centralized control of Twitter became problematic. If Twitter had remained more open or if there were stronger barriers to platform consolidation, we might have seen more diverse social media ecosystems develop naturally. The real issue isn’t acquisitions per se, but when they’re used primarily to eliminate competition rather than genuinely improve products. Markets work best with a mix - some consolidation for efficiency, but enough independent players to maintain innovation pressure.

Yes, forces do have a speed limit - they all propagate at the speed of light (about 300,000 km/s in vacuum).
If a black hole suddenly appeared right in front of you, you wouldn’t feel its gravitational pull instantly. Instead, the gravitational influence would spread outward from the black hole at light speed, creating what physicists call “gravitational waves” - ripples in spacetime itself.
So if this hypothetical black hole formed, say, 1 meter away from you, you’d feel its gravitational effects about 3.3 nanoseconds after it formed. If it were 300,000 kilometers away (roughly the distance to the Moon), you’d wait about 1 second.
This isn’t just theoretical - we’ve actually detected gravitational waves from colliding black holes using instruments like LIGO. When two black holes merge billions of light-years away, the gravitational ripples they create travel across the universe at exactly light speed until they reach Earth, where they compress and stretch space by incredibly tiny amounts.
Einstein predicted this behavior in his theory of general relativity over a century ago, but we only confirmed it experimentally in 2015. Before Einstein, people thought gravity acted instantaneously across any distance - imagine the chaos if the Sun’s gravity could suddenly “switch off” and we’d feel it immediately rather than waiting 8 minutes for that change to reach us!
