Space - Vastness and Beyond (and time travel)

Falcon heavy. 

When we think about space, we seem to be enchanted by its expanse. It is something big beyond imagination and filled with mysterious that we can not begin to unravel. 

How did the universe being? 
What is at the edge of the universe?
Can we travel to another galaxy? 

Falcon Heavy is a mere rocket. It is a big rocket, but it is trivial compared to the size of our universe. 

Picture by me from Pixel 2 XL.

Insatiable. 

It is pretty clear that human desire is insatiable. The best examples are ourselves. We wish for goals, we give up on them, we reach them, and we set other goals. Last week, I talked about the unreacheable state of complete satisfaction. Insatiable desire is merely another way of saying it. 

Falcon Heavy's launch brought me back to this topic. Elon Musk said something along the lines of wanting to make humans an interplanetary species. Everyone can share the primal human awe and desire to explore the universe, the unknown full of potential. We are, after all, insatiable. 

Dimensions. 

Through my ponderings of space and time, I thought of the dimension theory. 

There are infinitely many 0 dimension objects (points) in 1 dimension space (line).
There are infinitely many 1 dimension objects (lines) in 2 dimension space (plane). 
There are infinitely many 2 dimension objects (planes) in 3 dimension space (volume). 
There are infinitely many 3 dimension objects (volumes, or our universe) in 4 dimension space (universe timeline).

And so on. 

It is impossible to jump across a higher dimension with forces in the lower dimension. This means that it is impossible to time travel with 3 dimensional forces (up, down, left, right...). To effectively time travel backwards and forwards in time, we need a force from the 4th dimension itself. 

Think about cartoon characters on a movie screen. They are limited to move within the 2D screen, and we can only make them 3D by using our hands to interact with the screen or construct them or move them in our 3D space. Potentially, 4D capable entities can displace us across time. 

If 4th dimension is linear time, then 5th dimension is needed for worldline jumping.

Upside Down Snow Globe - The MacGuffin

Image
The Start I saw various snow globes many times in my life, but I only realized some of its implications a few moths ago, during my seventeenth year on Earth. Snow globes are pretty, expensive, and offer no practical value. They are the embodiment of the modern materialistic mindset: often found at tourist traps and bought at a high value as gifts and souvenirs. The only value they offer is perhaps a sense of awe that decays rapidly with repeated sightings. We can argue that they have sentimental values, but I rebut that all objects can have sentimental values, and therefor, snow globes are not better in that aspect. Picture from Flikr.  But, they are beautiful.  Even I cannot deny that. A majestic world with castles and sky scrapers inside a transparent glass sphere is beautiful. However, when I stumbled across deeper implications behind its attractive appearance, I started to ponder about the face values of happiness.   A world without snow is a sad one.  The world wit

The Searching Game

Image
Sometimes, we feel like we are missing something. We don't know what exactly we are missing, but we are sure we are missing it. When we walk, we hold our head up high and look around, searching for a hint, a clue, that will lead us to what we are finding. Most days are routine.  We get up, wash, eat, and drive. This repetition is boring, and we pay little attention to it. Now, imagine you wake up in the morning and eat oatmeal while clearly pondering about an aspect of your life. There is no rush. There is no grogginess. There is vitality. Art from Kimi no Na wa. What is the difference between the two lives? The one we live in right now and the one we are searching for? We don't know... That is why we are searching, waiting, and anticipating. Break compromise.  People often mention that we have to keep accelerating, keep moving forward with passion and zeal. However, we don't have that much continuous passion to spend; we are human, after all. We don't h

Sea of No Progress - Beginning of Continuity

Image
It has been a while. A few weeks since I wrote a post. Life gives a little and takes a little. I am back with a series, the continuity series. There are a few concepts in life that mesmerize me, and one of them is continuity. There is really no singular destination for us, but there is constant drive urging us to continue, whether it is to chase after our dreams or do something that we may not want to do.  Embark.  Setting sail is exciting! I believe in beginner's luck. When we start something, we get this exhilarating feeling of growth and satisfaction. We feel we are going in the right direction and we will be able to reap the rewards. However, as the port disappears into the horizon, we see nothing but sea. Art from Darling in the Franxx. Boundless.  Sea is boundless. Once we are in it, we are surrounded by miles upon miles of blue water. We can not tell where we are, because we have no reference. We only know that we are surrounded by water. This can get tiring
