5 Ways The World Could End - Part 2

This is a part 2 in the series "Ways the world could end". There are several threats to our existence. Some are man made and some are natural. In any case, we should be aware of them so that we can prepare for any doomsday event that might occur.

Let's take a look at five more ways the world could end.

1. Black Holes

There are black holes every where in the universe. Most galaxies have a super massive black holes at their centre towards which the entire galaxies are being pulled slowly but surely. But there are rogue black holes throughout the vast expanses of the universe devouring anything and everything in their paths.

These are the destroyers of worlds in the truest sense. Their gravity is so strong that even starts much larger than them are sucked into their black abyss and disappear into oblivion.

Scientist are tracking a lot of black holes but it is easy to miss some. Even if we could tell a black hole was coming straight at us, there would be nothing we could do about it. We would be utterly helpless. A slow wait would ensue. A wait for death to arrive and the world to disappear. There would be no earth left if one was to pass by.

2. Global Warming

This is a household term and therefore doesn’t strike fear in our hearts when we talk about it. It’s just global warming, right? No! Scientists say that this is perhaps the biggest threat facing the planet right now. This is the imminent threat faced by us that could just as easily end us if not dealt with.

Increase in global average temperatures, climate change, melting of polar caps, ozone depletion, are all either the results or byproducts of this. Our planet could end up like Venus where a typical day is 900 degrees Fahrenheit. It would literally be “hell on earth”.

Other implications of global warming are severe drought, famine, ecosystem collapse, increase in tropical pathogens. All these are equally dangerous and pose a great threat to us.

3. Solar Storm

The sun is a massive nuclear reactor in space. It is the source of our light and warmth. There would be no life without it. But since so much nuclear reaction is going on inside the sun that sometimes it results in solar storms.

Usually we are protected from the solar storms by the ozone layer. But other sun like starts have been shown to brighten up briefly by up to a factor of 20.

The sun has yet to have an episode like that. But in the scenario that does happen, it would destroy the ozone layer completely and fry the earth in a matter of hours. Such episodes are called Super flares and we may or may not see such an event for hundreds of thousands of years.

4. Gamma Ray Bursts

This is another threat that comes from outer space. Gamma ray bursts are extremely energetic explosions that occur during a supernova or hypernova, as a rapidly rotating, high-mass start collapses to form a neutron star, quark star, or black hole.

If a gamma ray burst was to happen in our galaxy, it would be a bad day for earth. It would destroy the atmosphere, the ozone layer, resulting in mass extinction, food chain depletion and mass starvation.

Such occurrences are rare but space is large and you never know what, when or where is something going to explode.

5. Global Epidemic

Throughout history the world has seen a lot of epidemics. Some of the more gruesome ones included the Black Plague that killed 25% Europeans during the 14th Century, the Smallpox, that killed 90 million Native Americans, the great influenza epidemic of 1918 that killed 50-100 million people in a single year.

The thing is, we share this earth with countless organisms, big or small. We never know which new virus or bacteria or fungi could be the cause of another global epidemic. Recent outbreaks like the Zika virus and Ebola have proven that.

There might be a deadlier organism that we don’t know anything about that has been lurking in the proverbial shadows all these years and could potentially kill us all or a large number of us. It has happened before, it can happen again.
