I am no astronomy or physics expert but here’s one cool thing to think about: How much do we have left on Earth? or more importantly… Will humanity survive the Earth’s death?
I never seem to be able to focus on what I have to do. Even when I have already exceeded my deadlines, I can’t put my brain to work. My mind’s always running around thinking about the most stupid things.
Many questions have always haunted me. Such as: Is the multiverse theory true? What about Gardner’s theory of multiple intelligences? Will we ever overcome the problem of qualia?
But the most frequently-occurring one is: Do we actually have a back-up plan?
What would we need a back-up plan for? you may ask.
There are plenty of theories about how life on Earth will evolve in the next hundreds or even thousands of years. Actually, there’s this YouTube video that pictures the rest of the Universe’s life:
These are all based on studies, data and statistics. Still, lots of unexpected things could happen. Such uncontrollable and unfortunate events could only defy all the theories we currently believe will come true.
What are the events that we are currently able to anticipate?
The Sun will eventually run out of fuel
Researchers say that humans will inevitably go extinct much more before the planet Earth dies.
They have also predicted that the Earth will die approximately at the same time that the Sun’s life ends. This is actually quite logical, the Sun is la pièce au résistance of our galaxy. Everything revolves around it, really.
The Sun’s mechanism is quite simple. In not-scientific words, it burns hydrogen into helium, thus the heat and light it emanates.
This theory says that when the Sun runs out of fuel, it will expand but will still burn for some time. This will cause all the planets from Milky Way to melt and stick to it.
The star has lived half of its life until now (it has burned half of the hydrogen it has started with into helium, so it is now made up of half hydrogen and half helium). Hopefully, humanity won’t live to see this.
A huge asteroid will hit Earth
An asteroid could hit Earth at any given moment in time. We can’t know if and when this will happen, but only with a few days before (that’s if we’re lucky).
The impact of an asteroid could be lessened by sending a big body in space which will then be the one hit. Of course, this has its cons too. If the body is too light, then the asteroid will absorb it and they will come together towards Earth but at a slower pace.
If it is too small, then the effects are similar, only that the asteroid will keep its initial speed.
Could we possibly save our species? If yes, how?
Even though reducing pollution will not elongate our life as a species for much… it will still help, whether this adds two weeks or two decades.
Right now, our planet is not doing so well health-wise. Keeping the Earth healthy is actually really important no matter if we find a way to keep life on Earth, or in our galaxy or not.
By leaving our planet (or even galaxy)
If the Sun expands and absorbs all the planets, that means that our only way to escape death by this hazard is by leaving our galaxy.
Thus, in the past few decades, scientists have been looking for planets that could be a home for us.
I feel like the future of humanity or Earth should concern all of us, not only scientists and researchers but also ordinary people. This is our only home.
Stay tuned if you want to find out what planets or galaxies we’ve found up until now similar to ours, that could also support life! Article coming soon!
