Map of Frontiers of Knowledge
Unsolved science mysteries: dark matter, the quantum measurement problem, the origin of life, consciousness and where the universe came from. Here we honestly present “we don’t know” — with evidence and hypotheses, asserting no answers.
knowledge frontier · open questionsDark Matter Vật chất tối & NL tối
Galaxy rotation curves defying prediction, gravitational lensing, the Bullet Cluster — ~95% of the universe is something we can’t yet identify.
Measurement Đo lường lượng tử
Superposition → ‘collapse’ on measurement; the double-slit experiment; the Copenhagen / Many-Worlds interpretations — the math works but the mechanism is unclear.
Origin of Life Nguồn gốc sự sống
Non-living chemistry → the first cell: Miller–Urey, the RNA world, hydrothermal vents — competing hypotheses.
Consciousness Ý thức
We can measure neural correlates, but why does matter ‘feel’ anything? The explanatory gap — the hard problem, still unsolved.
Cosmic Origin Trước / ngoài Big Bang
Where did the universe come from? Eternal inflation, cyclic cosmology, the multiverse — speculative models at the edge of the knowledge horizon.
Dark Energy Năng lượng tối
The universe expands ever faster — ~68% is ‘dark energy’ whose nature remains the biggest mystery in physics.
Quantum Gravity Hấp dẫn lượng tử
Relativity & quantum theory clash at the Planck scale — string theory vs loop quantum gravity, both untested.
Multiverse Đa vũ trụ
‘Multiverse’ means many things — from beyond the observable horizon to quantum many-worlds; mostly still speculation.
Life Elsewhere Sự sống ngoài Trái Đất
Habitable zones, biosignatures, the Drake equation & the Fermi paradox — searching, never yet confirmed.
Arrow of Time Mũi tên thời gian
The laws of physics are time-symmetric, so why does time have one direction? The past hypothesis is still an open question.
Fermi Paradox Nghịch lý Fermi
Trillions of stars, so where is everyone? The Drake equation + many competing hypotheses — an open, unsolved question.
Baryon Asymmetry Vì sao có vật chất
The Big Bang should have made matter = antimatter → mutual annihilation. Yet matter remains (we’re here!). Where did the tiny surplus come from? An open mystery.
Fine-Tuning Tinh chỉnh hằng số vũ trụ
Tweak a few constants slightly and there are no stars/atoms/life. Why are they ‘just right’? Multiverse, anthropics or a deeper theory — an open question.
Information Paradox Nghịch lý thông tin hố đen
Throw information into a black hole then let it evaporate. Does the information vanish (breaking quantum theory) or escape with Hawking radiation? Where quantum meets gravity — an open question.
Quantum Biology Sinh học lượng tử
Photosynthesis, the bird compass, enzymes — do quantum effects play a role in ‘warm & wet’ life? How long can quantum coherence survive? A young field, many open questions.
Discovered or Invented? Bản chất của toán học
Why does math describe the universe with unreasonable accuracy? Is math out there to discover or a human invention? A philosophical question at the foundation of science — still open.
What Is Life? Sự sống là gì?
Viruses, fire, crystals, AI — which are ‘alive’? Test them against 6 criteria then adjust the definition’s threshold. No single definition is agreed by all scientists.
Time Travel Du hành thời gian
To the future: proven (time dilation). To the past: the grandfather paradox, wormholes, self-consistency — speculative & possibly forbidden by physics. An open question.
Theory of Everything Lý thuyết về vạn vật
Unify the 4 forces + reconcile quantum theory with gravity in one framework. 3/4 done (the Standard Model) — gravity still stands apart. Strings, loop gravity: speculative. Open.
Simulation Hypothesis Giả thuyết mô phỏng
Do we live in a computer simulation? Bostrom’s trilemma & arguments on both sides. ⚠️ Philosophical speculation — no evidence, untestable, not a fact.
