100

Scientist who showed time is not absolute

Who is Einstein?

100

This term means disorder in a system

What is entropy

100

This ability lets us recall past memories

what is memory

100

Rovelli suggests this may not exist fundamentally

What is time

100

theory explaining how time and space are connected

what is relativity

200

Relativity proves that different observes can experience different versions of this.

What is time itself.

200

We remember the past and not the future because of this

what is lower entropy in the past
200
humans perceive time as this, even though physics disagrees

what is flowing or linear

200

time emerges from these instead of existing independently

what are relationships between events

200

study of the smallest particles in the universe

what is quantum physics

300

Time changes depending on these two factors

What is speed and gravity
300

Over time entropy generally does this

what is increases

300

Without this, time would not matter to us.

What is memory

300
In quantum gravity, time may do this

what is disappear

300

theory which combines relativity and quantum physics.

what is quantum gravity
400

According to relativity, there is no universal version of this.

What is the Present.

400

Without this concept, time wouldn't have a clear direction

what is entropy.

400

Rovelli argues the flow of time is this type of experience

what is subjective

400

there are many of these instead of one universal "now"

what are multiple presents

400

The idea that time is not universal but based on perspective

what is the relativity of time

500

This concept is how time slows down near large objects.

What is time dilation

500

The "arrow of time" refers to this direction

what is the direction of increasing entropy

500

this creates our sense of past, present, and future

What is memory and brain processing

500

reality at its deepest level is described as this

what is Complex and non-intuitive

500

bending of the spacetime caused by mass

what is gravity
