1/3: What is Space and Time?

What is Space and Time?
I’m glad you asked. Before I became a creative product designer and founder I studied Mathematics and Science in A-level.
Time is a mathematical understanding. Time itself is not a fact, it is an highly practical, but yet imprecise measurement tool that helps us understand things. Time is simply just a movement from A to B measured through space.
Experiment One — Walking on the floor
Imagine you are standing at the corner next to a 25 meter long swimming pool. The corner you are standing at is point A. Now I need you to walk to the other corner on the other side of the swimming pool. That will be point B. It takes you about 20 seconds to walk from point A to point B.
You just walked through Space in the measured Time of 20 seconds.
Experiment Two — Walking through water
Imagine you are in the point A corner of the same swimming pool, this time you are in the pool. The pool is one meter deep. Now I need you to walk 25 meters from point A to point B through the water. It takes you about 100 seconds, five times slower than walking on the floor.
You just walked through the same Space in the Time of 100 seconds.
How Density affects Space and Time
Space can have many forms. Space in air is less dense compared to Space in the water. Moving through air is faster than moving through water. The less Dense the Space is, the less friction you will experience moving. That is why objects can move so fast in the outer Space where the Density of Space is basically zero. Out there moving from point A to B can be much faster.
How Gravity affects Space and Time
Gravity is not an invisible force. We are just so deep in the larger picture that gravity feels invisible. The earth is technically falling, which means it is moving. When you jump you reach a friction of time where you stand still in the air before moving back down again. The moment you are still in the air is the moment you are falling in the same speed of the earth. Gravity pulls you back down because the earth is moving faster than you.
Experiment Three — Lifting your arms
I need you to lift both of your straight arms from your hips to above your head. You just moved your hands from point A to point B in… let’s say 1 second.
Experiment Four — G-force
Now I need you to imagine you are sitting in a super fast rollercoaster. I need you to lift both of your arms from your hips to above your head while the rollercoaster is moving super fast on its way up to a big loop. You will feel the gravity pulling all of your body down, making it harder to pull up your arms. A.k.a. the G-force. That is because movement through Space and Time shapes the Gravity.
Experiment Five — Negative G-force
Now I need you to lift your arms again, but this time while the superfast rollercoaster you are sitting in begins rolling downwards. You will feel a much lighter gravity making it much easier to pull up your arms. A.k.a. the negative G-force.
Experiment Six — Interstellar
A dramatic approach to understanding how Gravity affects Space and Time is by thinking of the water planet with the monstrous waves in the Interstellar movie. An hour on that planet is equal to 7 years on Earth. That is because the gravitational pull on that planet is much stronger than Earths, affecting every single movements from point A to B incl. Space and Time. Everything is just in hyper-slow motion.
In News Feed context: When you spend too much time on one Post, you lose Time you could have spent on other Posts.
Alright, but what have the experiments and science stuff above have something to do with the News Feed?
