Is it a bird, is it a plane, no it’s…

At first glance some may see a plane but on a later shot, it becomes clear it’s a seagull in the foreground and a water vapour trail (emitted from a plane) in the background.

Perception is subjective, what you see may not necessarily be what I see.

But what makes us see? It’s actually a simple mechanism, at first… It starts when light bounces off an object and into your eye. Upon detection by the retina, this light is converted into electrical signals and transmitted to the brain via the optical nerve.

It is when these electrical impulses reach the brain that the freak show starts. The brain translates this raw data into useful images…

Life Cycle Part 4

In the previous post we were looking into the Fermi Paradox and some of its possible solutions, here we’ll continue to explore more solutions to this paradox.

Another solution to the Fermi Paradox suggests that life on a habitable planet goes through “Great Filters”. These are near apocalyptic events that test the wits of life, they may have happened before our civilization formed (meaning we are already past the filter). Or, they are yet to happen (the Filter is ahead of us).

Palaeontologists have managed to unearth evidence showing that we may have already passed the filter. Through the geological timescale, Earth has gone through five major mass extinction events, these events were accompanied by major loss of life. Ranging from severe ice ages to cataclysmic volcanic eruptions, these events created intense climatic conditions that wiped out majority of species from the face of the Earth (palaeontologists notice this when…

Life Cycle Part 3

In my previous post, we discussed how it is kinda easy for life to form from simple inorganic compounds (abiogenesis). And since our galaxy is teeming with habitable planets, some being way older than Earth, why haven’t advanced alien civilizations found us?

First off, if there are advanced alien civilizations out there what would they look like? A Russian astrophysicist by the name Nikolai Kardashev hypothesised a scale ranking civilizations by their energy consumption, the Kardashev scale. The scale ranges from a Type 1 civilization to Type 3. (Later modifications stretch it till Type 6).

A Type 1 civilization will be able to access all of the energy available on its planet, e.g. solar, wind, geothermal, hydrogen, tidal, hydroelectric, fossil fuels e.t.c. Currently we are a Type 0.73 civilization and we will be entering Type 1 in the next several hundred years (i.e. assuming we would have figured out

Life Cycle Part 2

The song goes, “Our whole universe was in a hot dense state, then nearly fourteen billion years ago expansion started, wait…” Why the expansion?

bigbang Big bang illustrated

The universe tends towards disorder, meaning that from the hot dense point of the big bang, heat will spread out until it is evenly distributed everywhere achieving thermal equilibrium. i.e. the state of entropy of the universe will always increase over time. This is the 2nd law of thermodynamics. Even our solar system and planet formed in this similar process of heat dissipation.

Earth being fairly near the sun it was exposed to an ample amount energy upon which when reaching the water bodies it was absorbed. Some of this energy gets distributed into chemical bonds, forming simple molecules (Picture exited particles inside water zooming left right and centre knocking off atoms from molecules and bringing in new atoms in the bonds…
