[filed under theme 27. Natural Reality / C. Space / 6. Space-Time
]

A Reaction
[He cites Paul Davies for this] Is the universe acquiring more space, or is the given space being stretched? Acquiring more time makes no sense, so what is more space-time?
The
24 ideas
from Adrian Bardon
22889
|
We should treat time as adverbial, so we don't experience time, we experience things temporally
[Bardon, by Bardon]
|
22882
|
We use calendars for the order of events, and clocks for their passing
[Bardon]
|
22883
|
It seems hard to understand change without understanding time first
[Bardon]
|
22886
|
The modern idea of 'limit' allows infinite quantities to have a finite sum
[Bardon]
|
22884
|
The motion of a thing should be a fact in the present moment
[Bardon]
|
22890
|
We experience static states (while walking round a house) and observe change (ship leaving dock)
[Bardon]
|
22892
|
Experiences of motion may be overlapping, thus stretching out the experience
[Bardon]
|
22901
|
The B-series needs a revised view of causes, laws and explanations
[Bardon]
|
22900
|
How can we question the passage of time, if the question takes time to ask?
[Bardon]
|
22898
|
What is time's passage relative to, and how fast does it pass?
[Bardon]
|
22902
|
Why does an effect require a prior event if the prior event isn't a cause?
[Bardon]
|
22897
|
The A-series says a past event is becoming more past, but how can it do that?
[Bardon]
|
22896
|
The B-series is realist about time, but idealist about its passage
[Bardon]
|
22910
|
To define time's arrow by causation, we need a timeless definition of causation
[Bardon]
|
22909
|
We judge memories to be of the past because the events cause the memories
[Bardon]
|
22904
|
The psychological arrow of time is the direction from our memories to our anticipations
[Bardon]
|
22906
|
The direction of entropy is probabilistic, not necessary, so cannot be identical to time's arrow
[Bardon]
|
22907
|
It is arbitrary to reverse time in a more orderly universe, but not in a sub-system of it
[Bardon]
|
22905
|
Becoming disordered is much easier for a system than becoming ordered
[Bardon]
|
22903
|
The B-series adds directionality when it accepts 'earlier' and 'later'
[Bardon]
|
22911
|
At least eternal time gives time travellers a possible destination
[Bardon]
|
22912
|
Time travel is not a paradox if we include it in the eternal continuum of events
[Bardon]
|
22914
|
An equally good question would be why there was nothing instead of something
[Bardon]
|
22913
|
The universe expands, so space-time is enlarging
[Bardon]
