Full Idea
'Space' in physics really just means location.

A Reaction
Location can, of course, only be specified relative to something else. Space is really an abstraction, but at least it means there is some sort of background to locate all the fundamental fields.
The
20 ideas
from Gavin Hesketh
21181
|
Relativity and Quantum theory give very different accounts of forces
[Hesketh]
|
21180
|
Electrons are fundamental and are not made of anything; they are properties without size
[Hesketh]
|
21182
|
Quantum mechanics is our only theory, and is very precise, and repeatedly confirmed
[Hesketh]
|
21184
|
Physics was rewritten to explain stable electron orbits
[Hesketh]
|
21183
|
Thermodynamics introduced work and entropy, to understand steam engine efficiency
[Hesketh]
|
21186
|
Quarks rush wildly around in protons, restrained by the gluons
[Hesketh]
|
21185
|
Colour charge is positive or negative, and also has red, green or blue direction
[Hesketh]
|
21188
|
Quarks and leptons have a weak charge, for the weak force
[Hesketh]
|
21189
|
Electrons may have smaller components, bound by a new force
[Hesketh]
|
21187
|
Virtual particles can't be measured, and can ignore the laws of physics
[Hesketh]
|
21190
|
'Space' in physics just means location
[Hesketh]
|
21191
|
Photons are B and W° bosons, linked by the Higgs mechanism
[Hesketh]
|
21192
|
Neutrinos only interact with the weak force, but decays produce them in huge numbers
[Hesketh]
|
21193
|
The universe is 68% dark energy, 27% dark matter, 5% regular matter
[Hesketh]
|
21194
|
The Standard Model omits gravity, because there are no particles involved
[Hesketh]
|
21195
|
In Supersymmetry the Standard Model simplifies at high energies
[Hesketh]
|
21198
|
If a cosmic theory relies a great deal on fine-tuning basic values, it is probably wrong
[Hesketh]
|
21196
|
To combine the forces, they must all be the same strength at some point
[Hesketh]
|
21197
|
Standard Model forces are one- two- and three-dimensional
[Hesketh]
|
21199
|
Spinning electric charge produces magnetism, so all fermions are magnets
[Hesketh]
