We live in a magical world of interactive technology, space probes landing on comets, and refrigerators That judge you on what you are eating for dinner. But despite man’s many technological advancements… there are some devastatingly simple things which we still don’t understand. From what goes on in your head, to what’s lurking at the bottom of the ocean here are 7 things science can’t explain it.
1. Why Do We Dream?
What did you do during your last dream? Maybe you fought a giant purple dragon beast with the face of Rosie O’Donnell and the body of… Rosie O’Donnell.
Whatever it was it’s likely to have some relevance to your day’s activity or your psychological makeup, but what science can’t tell you about your dreams is what’s the point?
Through the detection of Rapid Eye Movement we can tell precisely when someone is dreaming and using brain. Imaging technology, we may even be able to view your dreams one day whilst dreaming your brain’s electrical patterns are just as active as when you are awake so clearly something important is going on.
Is your brain indexing the day’s thoughts? Perhaps your self-conscious is trying desperately to erase embarrassing memories or could it be that when we dream we experience some form of an alternate reality.
2. Are We Alone In The Universe?
Aside from a few exciting moments such as the set wow signal and the occasional flashing light in the sky science is yet to prove conclusively the presence of extraterrestrial life but nor has it proven that such life definitely doesn’t exist there are 40 billion habitable planets in our galaxy.
And that’s only if we can consider what carbon-based organisms like ourselves need to live on. The conditions which created life on earth are incredibly rare but, given the vastness of space and the diversity of conditions in which creatures live on earth.
It’s a long shot to say that there’s no chance of an alien life somewhere in the universe. we also need to consider our definition of extraterrestrial life because even though NASA predicts we may find something in the next 2 decades.
Its likely to be in the form of minuscule organisms that aren’t really capable of holding a conversation. 1 man who doesn’t want to wait 2 decades is Stephen Hawking who’s teaming up with Russian billionaire Yuri Milner to launch a project called breakthrough listen.
A plan which will help astronomers search 10 times the amount of sky previously surveyed and with 50 times the sensitivity enabling us to detect signals from 100 closest galaxies with greater accuracy than ever before.
3. What Is Human Consciousness?
If you’re watching this video you’re probably conscious. If someone hits you with a baseball bat you’ll be rendered temporarily unconscious and if they hit you a few more times before burying you in a shallow grave in the woods you should have been conscious of your bookie’s loan percentages.
But what is consciousness? and what happens to it when we die? at its most basic level consciousness is an awareness of your physical surroundings. something many living things also possess.
But what we don’t know is if our human level of consciousness is truly unique or if other organisms such as animals and plants are aware of their existence to. Human consciousness has developed far beyond knowing where food lives and where to take a whiz, but could every organism potentially develop this ability?
The electrical activity which occurs within the brains network of over a hundred billion nerve cells is a distinctly physical process. but the advanced consciousness it creates is something much more than a series of biological survival instincts.
So whilst at present neuroscience can tell us which parts of the brain are responsible for human consciousness. we really have no clue as to how it works?
4. What Lives At The Bottom Of The Ocean?
It is often said that we know more about space than we do the ocean and whilst this is hardly something you can accurately measure. It is true that we have a huge knowledge gap when it comes to the earth soggy bottom.
At present 95% of the ocean remains unmapped to a high degree of resolution and it is estimated that anywhere between one and two-thirds of all marine life has yet to be identified.
Of course, the easiest way to identify these creatures is to visit them but that’s not easy. The deepest part of the known ocean is Challenger Deep an area located in the Pacific in the southernmost part of the Mariana Trench.
At a depth of 30 6,200 feet, this place has only been visited four times by humans as supposed to six manned missions to the moon. But every time we do go we seem to make amazing discoveries.
On a recent visit in May 2016 by the unmanned deep Discoverer, we encountered a previously unknown new jellyfish species. So what else could be lurking down there in the murky depths of the ocean?
5. How Many Planets Are In Our Solar System?
As far back as Pluto was given an offensive release for being too little and diminutive you may think the response to this is basically right. 8 or 7 in the event that you trust the intrigue that Venus is a mystery blazing Death Star holding up to obliterate every one of us.
But in actual fact whatever number astronomers give us is just their best guess. Because despite our ability to detect galaxies light-years away we are still unable to accurately measure the number of planets in our solar backyard. There are two major areas of uncertainty in our solar system.
The first is the area between the Sun and Mercury which is far too bright to accurately analyze without going blind. One upright of attempting to map this area involves plotting the trajectory of Asteroids and using this data we’ve noticed that there is a suspiciously planet shaped gap in the asteroid belt 50 astronomical units beyond Pluto.
Oh and also there’s potentially a planet four times the size of Jupiter further beyond that. and one more thing, a theory posited by physicist Richard a Mueller claims there might even be a second Sun.
So regardless of how many objects there are in our solar system, it seems the one certainty is at some point we’re going to need a brand new song to remember them all.
6. How Do Bicycles Work?
Unless you’re a certifiable moron you know that to make a bicycle go forward you get on it and you pedal really hard. In any case, as far as real material science engaged with influencing a bike to remain upright.
The logical conclusion appears to differ with itself with each passing week. At in the first place, we thought a law of material science called the preservation of precise force was included.
Which is where your bicycles wobbling or leaning is canceled out by the steering axis which makes up your bike’s handlebars, in a way similar to how a gyroscope works. But in a 2011 edition of the science journal engineers proved that gyroscopic effects were not needed to make a bicycle stay upright.
Another theory called the trail effect was also ruled out by the experiment. so at this moment in time, we can tell you with accuracy the genetic makeup of a human being, but put that on a bicycle and make it deliver newspapers and we got nothing.
7. Why Do We Have Blood Types?
Do you know your own blood type? If not, there’s a very easy way you can find out. simply extract two liters of blood jump up and down repeatedly until everything goes grainy.
And when you wake up in the hospital just ask the nurse she’ll easily be able to tell you what blood type you are. But she can’t tell you why there’s such a thing as a blood type at all.
There are more than 20 different blood types which we believe that humans evolved around 20 million years ago. And whilst we don’t know why we do know that they all have different properties.
People with type A are more susceptible to smallpox whereas those with type B are more easily affected with E Coli infections. There seems to be a definite link between your vulnerability to disease and blood type.
But is there more to it than that. For example, there’s a theory that those with RH blood are actually aliens are you one you’ll have to bleed, find out.
