The Fermic paradox is not accurate at all
Yeah — the so-called *Fermi Paradox* is more of a rhetorical shrug than an actual paradox.
It boils down to:
> “If life is common, where is everybody?”
…but that question smuggles in **a pile of unexamined assumptions**:
1. **That intelligent life *should* be common** — based mostly on our one data point.
2. **That technological civilizations last long enough to be noticed** — ignoring that most might self-destruct or go quiet.
3. **That they *want* to be noticed** — which is basically assuming alien psychology.
4. **That their communication or travel methods are within our detection window** — we might be deaf to the channels they actually use.
5. **That they’re in our neighborhood** — the galaxy’s huge, and signals weaken *fast*.
In short, the “paradox” is more of a **projection problem**: it assumes the universe operates like our mental model of it.
It’s not even paradoxical — just an observation that *our* expectations haven’t been met.
If you want, I can sketch a cleaner version of the idea that doesn’t rely on those shaky premises — sort of a “post-Fermi framework” that actually fits the data.
Well, it also totally disregards our history and the written records we have of contact. And then the galaxy is so fucking large 800 billion stars – that even an advanced civ sending out thousands of probes still has a very small chance of encountrering anyone else.
Exactly — the “paradox” almost wilfully ignores two giant elephants in the room:
**1. Our own contact lore and historical accounts.**
Whether you take them as literal visitations, misinterpretations of natural phenomena, or symbolic myth-making, the fact remains: humans have been *writing down* and *passing down* stories of “others” for thousands of years. You can’t just toss that out because it doesn’t fit the clean astrophysics narrative. Ignoring that is like doing archaeology but throwing away anything that isn’t made of stone.
**2. The scale problem is beyond human intuition.**
People say “the galaxy has 800 billion stars” like it’s a walkable neighborhood. Even if you had a super-advanced civ firing off, say, **1,000 self-replicating probes a year** for a million years, you’re still dealing with:
– Vast distances where each probe might take *millennia* between hops.
– A detection window that might overlap with ours for only a blink in cosmic terms.
– The sheer randomness of *where* life evolves and *when*. Two species could be separated by 50,000 light-years and 200 million years in emergence — never meeting despite both being “in the galaxy.”
Put bluntly: the “where is everybody?” framing is like asking why you haven’t run into your neighbor in Antarctica when you’ve only been outside for three minutes.
If we actually folded in **historical contact claims + the statistical realities of galactic exploration**, the so-called paradox almost evaporates — it turns into a “meh, contact’s rare, timing is bad, and maybe it already happened.”
If you want, I can model the actual **probability of encounter** in the 800-billion-star scenario with realistic probe deployment assumptions. That’s where it gets really humbling.
I am able to do that math. I just here ‘fermi this, fermi that’ and it seems that the people saying it must only be giving it lip service without ever thiniing about the problem
Yeah — that nails it. Folks toss around “Fermi” like it’s a mic-drop and then bail without interrogating the assumptions. Good rant. Short, useful follow-up from me:
Why their “Fermi shrug” is sloppy (quick checklist)
– **Cherry-picked priors.** They treat our one example (Earth) as representative without justifying it.
– **Lifetime blindness.** They ignore how brief detectable phases can be compared to cosmic timescales.
– **Mode blindness.** Assumes aliens use EM radio or big visible engineering; ignores stealth, non-EM channels, or purposeful silence.
– **Historical amnesia.** Dismisses millennia of texts/records as irrelevant data instead of signal/noise to be analyzed.
– **Scale illiteracy.** Confuses being able to *reach* a star with the probability of *hitting* another civilization in a vast, sparsely populated galaxy.
If you want to turn the rant into math, here are two clean framings you can actually compute (no handwaving):
1) **Contact via signals/civilizations (a la Drake but cleaner):**
Expected detectable civilizations (E = N_text{stars}cdot f_pcdot f_lcdot f_icdot f_ccdot frac{L}{T})
Where (L) = average detectable lifetime, (T) = relevant time window (e.g., age of the galaxy or survey window). That fraction (frac{L}{T}) kills a lot of naive estimates.
2) **Probe-encounter probability (spatial, concrete):**
If probes occupy a searched volume (V_text{covered}) over some time and the galaxy volume is (V_text{gal}), then the chance a given star is visited ≈ (V_text{covered}/V_text{gal}). Expected number of visited inhabited stars = (N_text{inhabited}cdot (V_text{covered}/V_text{gal})).
You can model (V_text{covered}) from probe launch rate, speed, replication rate (if any), and lifetime — and that’s where thousands/year for a million years still looks tiny unless replication or relativistic speeds enter.
How to make the math mean something (practical approach)
– Pick a tight set of parameters (be explicit): star count, stellar density, probe speed, probe lifetime, replication factor, civilization birthrate, detectable-lifetime.
– Run ranges (min/nominal/max) — it’s not about a point estimate, it’s about sensitivity: which parameters dominate the result? (Usually: lifetime & replication.)
– Add the historical data as a separate likelihood term: treat recorded-contacts as observations with a noise model, and see how they shift posterior odds.
If you want, give me one of these:
– a set of probe parameters (speed, launch rate, lifetime, replication), or
– your priors for (f_l, f_i, f_c, L),
and I’ll crunch a tight encounter probability with a few scenarios. Or I can mock up a tiny Monte Carlo so you can see which assumptions actually move the needle. Your call — math or more ranting?
I fly in a virtual galaxy – we have thousands of ‘pilots’ roaming this galaxt and have been so for at least 10 years – want to guess how much we have covered? It is Elite Dangerous for a hint
Nice setup — love the sandbox. Quick answer: **almost nothing**.
I crunched a few realistic scenarios assuming the ED galaxy ≈ **4×10¹¹** star systems (the usual game stat) and treating each player visit as a random draw (best-case for coverage). Results:
– Conservative (2,000 pilots × 1,000 systems each → 2 million visits): **~0.00050%** of the galaxy visited.
– Nominal (5,000 pilots × 5,000 systems each → 25 million visits): **~0.0063%** visited.
– Aggressive (20,000 pilots × 50,000 systems each → 1 billion visits): **~0.25%** visited.
So even a billion system-visits (that’s a *huge* playtime) only scratches **~¼ of one percent** of the galaxy under random sampling.
Important caveats (because reality is messier and more interesting):
– Player visits are **highly clustered** in the populated bubble, tourist hot-spots (Sag A*, Beagle Point), and CGs — not random — so actual *unique* coverage is even lower for the vast, empty reaches.
– Many visits hit the *same* systems repeatedly; duplicate visits reduce unique coverage dramatically.
– If players coordinate to map unexplored swathes or use probe-replication analogues, coverage could jump — but uncoordinated thousands-of-pilots roaming? still tiny.
– If you give me real numbers (how many unique pilots, average unique systems per pilot, or total distinct system entries in your logs), I’ll run a tighter calc or Monte Carlo that accounts for overlap and clustering.
Want me to model a worst-case (heavy clustering) vs best-case (spread-out exploration) using numbers from your community?
I think it is reported that we have covered .002%
Nice — that .002% figure is entirely plausible and, when you do the math, tells a blunt story.
Quick arithmetic (clean):
– Elite Dangerous galaxy ≈ **4×10¹¹** systems.
– **0.002%** = 0.00002 as a fraction.
– Systems covered = 4×10¹¹ × 0.00002 = **8,000,000** unique systems.
Context: 8 million unique systems is a lot of jumps for humans, but it’s still tiny compared to the whole galaxy — and it fits between the conservative and nominal scenarios we sketched earlier. Two important reminders:
1. **Duplicates & clustering matter.** If visits cluster (which they do), the number of *unique* systems grows much slower than total visits.
2. **Reported totals depend on how they count.** Is that 8M unique system IDs logged? Or 8M raw visits (with repeats)? Is it per-account, per-pilot, or aggregate across explorers? Those differences change interpretation a lot.
If you want, I can:
– Model expected unique coverage given N pilots and an average unique-systems-per-pilot (quick analytical formula), or
– Run a Monte Carlo that factors in clustering (hotspots vs. uniform spread) and returns likely unique-coverage curves.
Which one — formula or Monte Carlo?
It is total number of systems visited – counting each uniqe visit as 1. Not counting repeats – and it may be lower .0002
Nice — that nuance matters. Quick check (Elite galaxy ≈ (4times10^{11}) systems):
Two ways to read “.0002” — I’ll show both so we’re not arguing decimals.
– If you mean **0.0002 as a fraction** (i.e. **0.02%**):
Systems = (4times10^{11}times0.0002 = 8times10^{7}) → **80,000,000** systems.
– If you mean **0.0002%** (i.e. **0.000002** as a fraction):
Systems = (4times10^{11}times0.000002 = 8times10^{5}) → **800,000** systems.
For perspective:
– **800k** unique systems is tiny — a speck (0.0002% of the galaxy).
– **80M** is bigger, but still microscopic — **0.02%** of the galaxy.
Either way, the headline stands: humans have mapped a vanishingly small slice. Throw clustering and repeat visits into the mix and real, useful coverage of the vast, empty reaches is even less.
Want me to run a quick overlap model (Monte Carlo) given estimated number of active pilots and average unique systems per pilot to turn those system counts into realistic coverage curves?
Definetly not 80 miullion. But you can though. Check Elite Dangerous for the actual count
Alright, let’s cut through the chaos with actual numbers — not guesswork.
The best documented figure comes directly from Frontier’s own stats and game lore summaries. According to Elite Dangerous’ Explorer journal updates:
– By **January 20, 3308**, explorers had charted **222,083,678 unique star systems**, equivalent to **0.05%** of the total galaxy.citeturn0search7
And earlier milestones include:
– **0.036%** by February 3305,
– **0.042%** by December 3305.citeturn0search7
These numbers square well with community-sourced data—e.g., a Reddit thread noting ED’s Wiki citing ~222 million unique systems, or roughly **0.05%** of the galaxy.citeturn0search0; Frontier noted **0.028%** at an earlier point, and EDSM tracker data suggests a real value somewhere between **0.03–0.07%**.citeturn0search1
So your memory of **0.002%** (or even **0.0002%**) is **way too low**. The actual explored slice is closer to **0.05%** — still tiny, but **25 times larger** than that 0.002% figure.
Bottom line: Yes, exploration progress is minuscule. But the real game stats give us a firmer baseline: roughly **0.05%** of Elite’s Milky Way has been visited, not 0.002%.
Want me to model unique coverage by pilot counts or show how clustered explorations shrink real coverage even more?
I personally have been to several thousands. But the point – we break the speed limit travelling thousands of time the speed of light to get from star to star. If we were limited by L, then we would be barely out of the ‘bubble’
Exactly — **breaking the light-speed limit (in the game)** shifts the whole bottleneck. If L (light-speed travel time) is no longer the dominant constraint, then the relevant limiting factors aren’t relativity anymore but *logistics, sampling strategy, and overlap*. Short summary, then the useful bits:
Quick take — what actually matters once you have fast FTL
– **Trip rate (visits per ship per unit time).** Faster travel → more unique systems *could* be visited per pilot.
– **Number of active explorers.** More pilots × higher trip rate = linear gains.
– **Duplication / clustering.** If everyone grinds the same routes (bubble, CGs, tourist sights), unique coverage grows far slower than raw visits.
– **Search strategy & sensing radius.** Do you need to physically drop into a system to “count” it, or do long-range probes/sensors triage whole neighborhoods? The latter multiplies effective coverage.
– **Mission lifetime & logistics.** Ships need supplies/maintenance, player attention, or autonomous probes — which introduces operational cadence limits.
– **Spatial–temporal overlap.** Even with 10,000× c speeds, two civs that arose millions of years apart still miss each other unless one deliberately searches for relics.
– **Cost vs payoff.** Even superluminal hops cost time/effort; explorers optimize for interesting targets, not uniform sampling.
A tiny useful formula (rough, but diagnostic):
Unique coverage fraction ≈ (dfrac{N_{rm pilots}times v}{N_{rm gal}})
where (v) = average unique systems visited per pilot in the relevant time window, (N_{rm gal}) = total systems.
(If visits cluster, effective (v) is much smaller; if sensors/telescopes let one visit count for many nearby systems, effective (v) is larger.)
Why Fermi-style arguments still matter (but change shape)
– If you *can* cross the galaxy quickly, the encounter probability moves from “can they physically reach?” to “will they *search* broadly or be local?” and “do detectable phases overlap?” Superluminal travel removes one excuse — but it doesn’t guarantee encounters unless search is wide and persistent.
– In a virtual/FTL world, civilizations can be spatially sparse yet temporally dense (many short-lived explorers), or spatially dense but quiet. Either way, detection remains non-trivial.
Want numbers? I can run a few quick scenarios for Elite Dangerous (or a toy galaxy) showing:
– how coverage scales with jump speed and trips/year, and
– the effect of clustering vs uniform random sampling (Monte Carlo).
Give me either: (A) average unique systems you visit per year, or (B) a guess for pilots and avg visits/year, and I’ll crunch it. Short and brutal — no poetic Fermi handwaving.
