- You might find it unsettling to know that many of the things that affect you on a daily basis in this world are still a mystery to humanity. Everything from the
cure for the common cold to our solar system, and even consciousness itself
has not been explained. (woman screaming) Here are 10 mysterious discoveries
that remain unexplained. (eerie music) Number 10 is the inside of a black hole. What's just outside of a black
hole has been documented. Specifically everything
within the event horizon, a point where gravity pulls so strongly that something would have to
achieve the speed of light just to escape being pulled inside. However, that being said,
even light is sucked in and made absent, hence
the name black hole. But what's inside of these
invisible gravity wells in space, we simply don't know. But what might surprise you even more is that we can't even see them. The only way that we even
know that they're there is because of the affect that they have on the space and the light around them. The prevailing theory is that inside there's a one-dimensional
point called a singularity where density and gravity become infinite, curving space-time equally infinitely. But until we can find a way
to effectively look into one, no one can know for sure. Number nine is the cure
for the common cold. With all the cures and vaccines that humankind has developed, you would think something
like the common cold would have to be dealt with by now. And it's not even that there's a lack of subjects that carry it. In fact, the word common
is right in its name. Doctors and scientists
have developed treatments and offered up remedies
to sooth the symptoms, however there is yet to be an
actual cure to the illness. However, that being said,
an important discovery might very well be right on the horizon. According to a paper
published in January of 2016, we could see an immunization that pumps up our immune systems to the
point that a rhinovirus, or viral agent responsible
for the illness, wouldn't affect us. Unfortunately at the current moment, there's no way to completely
keep yourself safe from the common cold, or the effects that might come with it. Number eight is time travel. You probably look at
time travel the way that most others do, as a
piece of science fiction with no real basis in the real world. Other than our desires to go back and maybe right some wrongs that we or others have committed. But the subject does get attention in the scientific community. In fact, some of the most
famous minds in science have made theories on it, including Albert Einstein
and Stephen Hawking. For instance, Einstein
theorized that if you traveled through space-time at
roughly the speed of light, time would slow down for
you while moving normally for the rest of us. After say five years at that pace, you might come back to
find nearly 50 years have passed here and all
your friends have become old. But that's just going forward. There could one day be a way to go back, we just haven't discovered it yet. Number seven is consciousness. Incredibly, something
that you're experiencing this very moment, is
also something you likely barely ever think about. Possibly because you don't
know exactly what it is. The top minds in psychology have wrestled for most of their lives with
one very large conundrum. What is consciousness? The truth is, despite a number of people trying to explain it, there is no accepted answer. After all, ask yourself
at this very moment, how do you know that you are what you are? We're aware that we live, but consciousness is not a tangible thing, so it's frustratingly
hard to put into words. We can map the brain and determine how it gets blood or communicates with other parts of our body, but just how your brain
matter is stuck together in your head, and how it actually thinks, that's a mystery that
has yet to be solved. Number six is alien life. It's becoming harder and harder to justify the idea that
we're alone in the universe. There are at least 100
billion stars in the universe, and as many as 50% of them have a system of planets orbiting them. Millions upon millions of
planets far away enough from their star to be
capable of supporting life could be out there, so the odds of finding it should be high. However, it's just that
the universe is colossal, and we're incapable of seeing it all. The discovery of alien life
would change the entire world, causing curiosity, panic,
and a race to communicate, and even reach them. But until solid evidence of
another habited planet is found, or first contact is
made with an alien race, the very existence of
extra-terrestrial life is just a theory. But not so much if, but when
it is finally discovered, it could have devastating
impacts on our society if our consciousness does not
change to be more accepting. Number five is the cure for cancer. Alarmingly, cancer is
the second leading cause of death worldwide behind heart disease, claiming 8.8 million lives in 2015 alone. The biggest killers being
lung and liver cancers followed closely by colorectal,
stomach, and breast cancers. These diseases are devastating
the world's population, and tens of billions of
dollars are spent every year on cancer research. Yet curing it is completely
still out of our grasp. Doctors can throw chemicals, scalpels, and even nanoparticles at it,
but it continues to plague us. Luckily for some, the
advancements in cancer treatments and therapies have allowed
people to live longer with the disease. And some even going into remission. But until there's a cure, cancer is one of the scariest words
a human being can hear. Number four is why do we dream? Whether you find yourself
soaring through the clouds, or having a disturbing nightmare, dreams can be entertaining, disturbing, or downright confusing. But the most confusing thing about them is why we experience them at all. Whether you remember them or not, every time we go to sleep, we dream. With some experts claiming that we have four to six every night. Nearly all of which, like
I said, are forgotten. We know that they're the
product of the brain, and there's been plenty of
progress in interpreting them. But despite this, we can't
explain why they happen. Perhaps they're our brain's way of understanding a problem
that we're struggling with. Or a way for our subconscious to express our hidden fears and desires. Until there's a breakthrough
that tells us otherwise, we'll be left in the dark. Number three is how did life begin? The question is eternal. How did life come into being? It's a very big question that's left scientists scratching their heads for as long as humans have been around. One that will likely prove
near impossible to answer. The prevailing theory
of how humans got here involves our prehistoric
ancestors crawling out of the sea and adapting to land dwelling. Hydrothermal vents in the
ocean contain plenty of energy, and it's believed that
life could have originated as molecules within one. However, some argue that life began in small pools of water that
existed close to volcanoes that dried up and then formed
again through weather cycles. Discovering exactly how life formed could give us the ability
to more easily create it. So perhaps it's a question that we're not supposed to answer. Number two is immortality. Imagine never having to attend a funeral for the rest of your life. Or for that matter, anyone
having to ever attend yours. That's the discovery that many doctors and scientists claim that
we're getting close to. Immortality. Whether it's through medical advances that sustain us as humans, or a future inside technology, our lives could theoretically never end. As medicine develops, so
does our understanding of how and why we age, and that could bring
about a way to slow, halt, or even reverse the aging process. Alternatively, as our bodies close in on their expiration date,
technological advancements may step in and supply us with a new body. Human minds inhabiting android bodies may seem too sci-fi to be true, but believe it or not, both of
these life-extending methods could exist in our lifetime. And number one is before the big bang. As science gathers more and more evidence proving that the big bang created the universe as we know it, one question continues to plague us. What came before it? Currently there's nothing to show us, so all scientists can do is theorize. One idea says that we're
all just in a time loop, and that the universe will continue to expand and then compress, creating and then extinguishing all life. Another says that the universe
may actually be one of many. Each with its own laws and
physics and its own time. Think about it, life is
practically a miracle considering everything that would have to go right for its creation. But with an infinite number of universes, there's bound to be
one, in this case ours, that supports it. There are hundreds of other theories about what came before the big bang, but for now that's all
that they are, theories. So, 10 mysterious discoveries
that have yet to be explained. But what do you think of
all these discoveries? Leave a comment below and let me know, and I'll see you in the next video. (eerie distorted whistling)
