The Science of Dark Humour | Hri-write

I'd like to begin by saying this blog isn't meant to offend anyone. It's all for the sake of fun and entertainment, and to satisfy my sadistic desideratum. If you're easily offended, or if this blog offended you in any way, it's because it was meant to.

(If that last line offended you, get out right now. It's going to get much worse.)



It might be worthwhile to address the question of 'why we laugh' before dealing with comedy styles such as dark humour.
We believe laughter evolved from the panting behavior of our ancient primate ancestors. Today, if we tickle chimps or gorillas, they don’t laugh “ha ha ha” but exhibit a panting sound. That’s the sound of ape laughter. And it’s the root of human laughter. Apes laugh in conditions in which human laughter is produced, like tickle, rough and tumble play, and chasing games. Other animals produce vocalizations during play, but they are so different that it’s difficult to equate them with laughter. Rats, for e…

TRAPPIST-1 (meet the 7 earth-like exoplanets!)


"Astronomers have discovered the first known system to host seven Earth-size planets around one star, and it lies just 39 light-years away from our own solar system." - Space.com
Unless you live under a rock, you heard this week that NASA disclosed a groundbreaking discovery regarding the TRAPPIST-1 system, containing 7 Earth-like planning potentially supporting life. Anticipation was mounting from the 24 hours before the announcement was going to be made, and when it did occur, there was a bombardment of articles/videos about it everywhere you could look. Justifiably so, the discovery (more of a confirmation of what was already known, but we'll call it a discovery) set the record for most habitable exoplanets found in a system or something crazy like that (don't quote me on that!).


This is an Artist's representation of what the views from the planets may look like.


Here's the breakdown:

Brief:


TRAPPIST-1 is a star like our sun, but cooler (I'm talking about temperature) and smaller. Known as an 'ultra cool dwarf' star, it currently has 7 Earth like bodies orbiting it. The reason this has been blown out of proportions is because of the nature of media today, majorly sensational and looking for the next headline to lure readers/viewers in. While the discovery is truly monumental, I'm going to have to burst the bubble and put things into perspective a little.

The system is approximated to be ~40 light years away. Getting there? Piece of cake.
Piece of difficult cake.

A light year is a monstrous distance, and even that is an understatement. A light year, by definition is the distance light will travel in vacuum in one year. To put it in perspective, in one second light can travel around the equator of Earth. Seven times.

You get the idea. It's unlikely we'll be visiting them anytime soon, but we shouldn't just give up.

A comparison of TRAPPIST-1's planets and our solar system's rocky planets.

How the discovery was made: 

TRAPPIST is a telescope (Transiting Planets and Planetesimals Small Telescope) which is operated by the ESO's La Silla observatory.

TRAPPIST is controlled from Liege, Belgium, with some autonomous features. It is a reflecting telescope 0.60 m (23.5″) in aperture diameter and is housed in the dome of the retired Swiss T70 telescope. - Wikipedia

A team of Astronomers and scientists used the TRAPPIST scope to observe the ultra cool dwarf star  2MASS J23062928-0502285, now named TRAPPIST-1. By using a method known as Transit Photometry, they identified and recorded 3 planets innermost to the star in the habitable zone of it. 

How they apply Transit Photometry:
Observing the planets passing by the background of the bright star to identify them.
Once this was confirmed, ground based telescopes were used in different locations on Earth to record and analyse the same, so that they may compare their readings to ascertain more accurately. Some models developed by the researching team suggest that the 3 planets in the habitable zone are the likeliest to sustain extraterrestrial life, and may even contain or have had water on them. 

Since ground based telescopes are limited by many variables such as weather, the initial observations were only superficial and preliminary, but then the Hubble Space Telescope caught wind of the report and is now being used to study the system, since it has an eagle's eye view from there, uninterrupted by light pollution/air pollution or weather.
"Detailed characterization — and the search for signs of possible life, such as oxygen and methane — will have to wait until more powerful instruments come online, Triaud said. But that wait shouldn't be long: NASA's $8.8 billion James Webb Space Telescope is slated to launch in late 2018, and huge, capable ground-based scopes such as the European Extremely Large Telescope and the Giant Magellan Telescope are scheduled to come online in the early to mid-2020s." - Space.com

VSAUCE did an amazing video titled, "Will we ever visit other stars?" which effectively sums up the possibilities and impossibilities of interstellar travel, if you're interested, watch it below:



This is an excerpt from the team that was researching TRAPPIST-1. 

"All the planets in the TRAPPIST-1 system transit their star, meaning that they pass in front of it. The planets were discovered from the regular and repeated shadows that are cast during transit. Thanks to the transit signals we could measure the orbital periods of the planets and could calculate the sizes of the planets. The exact time at which the planets transit also provide us with a means to measure their masses, which leads to knowing their densities and therefore their bulk properties. The planets are consistent with a rocky composition. We found that the planets have sizes and masses comparable to the Earth and Venus. Because we know the distance of the planets to their star, and the temperature of the star, we can deduce that they receive an amount of light that is similar to many of the planets in the Solar system, from Mercury to beyond Mars."

Conclusion

While TRAPPIST-1 may be an incredibly astonishing discovery, its relevance to us has been overhyped and taken to the next level by the news. Many things are uncertain, others unknown and some probable. We don't really know what to expect yet, and as the team working on this themselves said 'We can expect that, within a few years, we will know a lot more about these planets.'

I leave you with this incredible representation of TRAPPIST-1.
As always, thanks for reading.

Where is all the 'alien life?' - Fermi Paradox and other theories

My first blog, ever, was about understanding the odds of alien life. I've gotten much better at writing blogs since then (or so I like to tell myself), and it would only be right if I reinstate the legacy of that one.


We should openly admit that when we happen to be under a starry night and see a sight similar to this, we all have a react in a different and interesting way. Some people are left boggled by the immense size of the universe, others by the sheer glamour of the scene and if you're anything like me, you're paralysed by the sudden realisation that you have a negligible impact on the universe. The point is, we all feel something.

When he looked up at the sky, Italian physicist Enrico Fermi too felt something, a thought that lingered around this question, "Where is everyone else?" It's been half a decade since Fermi passed on, but he left us with a fundamental query and idea.

Fermi realised that in a universe as old and vast as this, there should be…

Understanding extremist terrorism

While I hate to talk about such a grim, dark topic, terrorism is running rampant across the globe, and there just seems to be no end. In 2017, the face of terrorism are organisations like ISIS. So, what exactly is terrorism? Merriam-Webster calls terrorism "the use of violent acts to frighten the people in an area as a way of trying to achieve a political goal."

Let's face it, terrorism isn't new. It's been around for a long time. The word, in fact, dates back to the late 18th century around the time of the French revolution. So why is it such a big deal now?

Because now terrorist organisations aren't local. They are getting more radical, and they don't just have political agendas. They've become irrational, crazed with the idea of securing the world under their woeful grasp.


To understand terrorism, it's essential to understand where it begins. All terrorist activities are motivated by one or two things, social/political injustice or the idea th…

The Psychology of External Validation

A recent conversation intrigued me to explore this topic, and I find it perhaps one of the most relevant ones I have written about. So, here goes.

I've known people who always get hundreds of likes on their posts hours within posting them. I have never been one of these people. I've never received many likes or shares, and when I was in my younger years, it was hurtful, in a way. I used to see my posts and shares sit on my wall for days with only a few likes, and back then, it was painful for me, so to say. It made me doubt my worthiness, and created a feeling that no one cared about what I had to say. I used to post a lot on Facebook just to see how many likes/shares/comments would accumulate in a few hours. I would be disheartened when that number didn't live upto my expectations. I'm sure some of you have had this feeling, and it's okay.

Why? Why, just why is it like this? Why do we doubt our worth, why do we feel so bad just because someone didn't press or…
