Transcript of Time:

Presumed to Be What We Made It
A Presentation by Michael Sumner
"When you have two competing theories that make exactly the same predictions, the simpler one is better."
-William of Occam
Time Toolbox
Despite our assumed understanding of the concept of time and its presumably unchanging systematic properties, time may be no different than all other objects, in which case acknowledging time as a separate entity would be wrong.
The Second Law of Thermodynamics
A Paradox
Planck Epoch
No Boundary Condition
Moments, or specific orientations of matter, are reliant on a constant and forward moving time.
"Entropy is the measure of how disorderly things in the universe are."
What if organization is increased?
"This Universe?"
are insignificant
It's all about the scope...
are a rarity
The Multiverse
Far more than minutes and seconds
Time is very relative
Matter entangles itself in what we call entropy: a form of time
Time paradoxically does not have a beginning
But how does any of this apply to life...?
The psychological arrow explained
Importance and relevance to life
Long term
Short term

To Humans:
Eminent death
Variances in Perception
Critical Flicker Fusion Frequency
Trinity College Dublin, Ireland
Among Species
Among Humans
-The greater the visual data per second, the slower the perceived time passing
Time in the Universe
What we perceive is relative. Why?
t=some #
X, Y, Z + time= 4D
Absolute Time
Future light cones
The absolute vantage point is impossible to reach...
Gravity and Time
Increases frequency of electromagnetic waves
causes atomic clocks to tick slower at lower altitudes
Time Dilation
And the Twin Paradox
...A round-trip to a neighboring star and back at 0.6C renders identical twins simply brothers.
E =P C +M C
Speed dictates the rate of moments passing: time

Time Travel Via Wormhole
A portal through time and space
What if the traveling twin went through a wormhole instead?
Applied to General Relativity
Why it can't happen
1 light-year is equivalent to 299, 792,458 m/s (or 186,000 mph)
Special Relativity
General Relativity
Mass-Energy Equivalence
Quantum Mechanics
Speed of Light
Time's 3 Arrows
Cosmological Arrow
(Cosmological Constant)
Second Law of Thermodynamics
Psychological Arrow
("A boiling pot")
Time: "Fibers relating objects together, relative to location"
E =P C + M C
t=time (in years)
eta=est. time of arr.
C=speed of light
V= voyager
when t=0
eta=10yrs, A=A , S=0
t=immediately after departure
eta=8 yrs, A<A , S=0.6c
eta=10 yrs, A=A, S=0C
T=arrival at destination
eta=0, A=A +8, S=0
eta=2 yrs, A=A +8, S=0
from A ,
8 yrs
10 yrs
A at arrival back to Earth=
A / A+4
"Time is in the eye of the beholder."
"Realize how insignificant this system that orchestrates daily life is."
"Different people will formulate different beliefs."
