Physics Topics (27)
Spacetime Physics
0

Spacetime isn't actually smooth; at the quantum level, it's believed to be "foamy" and incredibly turbulent. elaborate

Wormholes Physics
1

Wormholes, if they exist, could potentially allow for faster-than-light travel, but traversing one might require navigating exotic matter with negative mass-energy density – a substance we've never observed. elaborate

Particles Physics
2

Some particles, like neutrinos, can pass through the entire Earth without interacting. elaborate

Energy Physics
3

The energy contained in a single lightning bolt could power a 100-watt lightbulb for over three months. elaborate

Quantum Entanglement Physics
4

Quantum entanglement allows two particles to be instantaneously correlated, regardless of the distance separating them – a phenomenon Einstein famously called "spooky action at a distance." elaborate

Relativity Physics
5

Relativity predicts that time passes slower for objects moving faster relative to a stationary observer – a phenomenon known as time dilation. elaborate

Superconductors Physics
6

Some superconductors, when cooled below their critical temperature, exhibit the Meissner effect, completely expelling magnetic fields from their interior. elaborate

Fields Physics
7

The Fields Medal, one of the highest honors in mathematics, is awarded every four years and is limited to mathematicians under 40 years old. elaborate

Cosmology Physics
8

The observable universe is only a tiny fraction of the entire universe, which may be infinitely large. elaborate

Gravity Physics
9

Lab-grown meat, or cultured meat, uses significantly less land and water than traditional livestock farming. elaborate

Waves Physics
10

Waves can be found not just in water, but also in light, sound, and even earthquakes. elaborate

Time Travel Physics
11

The grandfather paradox, a classic time travel conundrum, is actually a plot device more than a scientifically sound problem, as it assumes a fixed, linear timeline that might not exist in theoretical models of time travel. elaborate

Quantum Physics
12

Quantum entanglement allows two particles to be linked regardless of the distance separating them, meaning a change in one instantly affects the other – even if they're light-years apart. elaborate

Thermodynamics Physics
13

The efficiency of a heat engine is fundamentally limited by the temperatures at which it operates; you can never completely convert heat into work. elaborate

Spectra Physics
14

Spectra, in the context of physics and chemistry, are often unique "fingerprints" for substances. No two substances have exactly the same spectral signature. elaborate

Light Physics
15

Light from the sun takes about 8 minutes to reach Earth. elaborate

Photonics Physics
16

Photonic chips, similar to microchips but using light instead of electricity, can process information significantly faster and more energy-efficiently than their electronic counterparts. elaborate

Matter Physics
17

Most of the matter in the universe is dark matter, which we can't see or directly interact with. elaborate

String Theory Physics
18

String theory requires more than the usual three spatial dimensions and one time dimension; it proposes the existence of extra, curled-up spatial dimensions that are too small to observe directly. elaborate

Stringtheory Physics
19

String theory requires more than the usual three spatial dimensions and one time dimension; it posits the existence of extra, curled-up spatial dimensions unseen at macroscopic scales. elaborate

Retrocausality Physics
20

Retrocausality, if true, could mean that future events could influence the past, potentially explaining some quantum entanglement phenomena. elaborate

Dimensions Physics
21

String theory proposes the existence of up to 11 dimensions, most of which are curled up and invisible to us. elaborate

Antimatter Physics
22

A tiny amount of antimatter is naturally produced in Earth's atmosphere when cosmic rays collide with air molecules. elaborate

Time Physics
23

There's no single, universally agreed-upon "beginning" of time. Our current understanding of physics suggests a point called the Big Bang, but what, if anything, came before it remains a mystery. elaborate

Tides Physics
24

Tides can actually affect the Earth's rotation, slowing it down very, very slightly over incredibly long periods. elaborate
