- In a universe that's constantly
expanding into infinity, unexplained and strange
things present themselves all the time but of those
things that we can observe, there are 10 that are
particularly fascinating and mysterious that nobody
can explain to this day. (dramatic music) Here are 10 mysterious space anomalies that we can't explain. Number 10 are black holes. Though scientist have
been studying black holes for a long time, there
are still more questions than answers when it comes to what we know about these intense and
sometimes scary space anomalies. A black hole is an invisible space with so much pull that
even light can't escape being drawn in. The only reason that we
know that they're there is because of the reaction that they have to other things in space. Because we can't see them, it's difficult to determine
what exactly they are or for that matter, what
happens to everything that gets sucked into them. One of the most popular
current standing theories is that everything inside a
black hole gets compressed with mind-boggling force. In fact, it's believed that a
black hole the size of an atom can actually have the mass of a mountain, just one of many unsolved
questions of the universe. Number nine are Saturn's rings. When you picture the gas
giant that is Saturn, there's really no way to not visualize the mammoth colorful rings surrounding it and while science has determined that the rings that you're picturing are made up almost entirely of ice with trace elements of rocky material, what hasn't been determined yet is how they formed or
why they're made of ice and for that matter, how
they manage to remain so incredibly flat. There are also some gaps between the rings that have no reason to be there. While some features of the rings suggest that they were
formed when the plant formed an estimated 4.4 billion years ago, other properties suggest that they're actually more
of a modern development. It's very possible that
Saturn might just be the most mysterious planet
in our solar system. Number eight is Tabby's Star. Situated nearly 1,500 light years from us is a star called Tabby's Star. It's a bit larger and definitely hotter than our sun which is
admittedly not an anomaly. However, what is is that for some reason its light has been spotty, dimming as much as 22%
since its discovery. The phenomenon has brought
forth a number of theories. Some believe that there are
a number of large comets or dust orbiting the star while some actually think that there could be an alien race using advanced technology
to siphon energy from it. Whatever the reason, the truth continues to elude humanity which means anything could be out there. Number seven is Jupiter's red spot. The most iconic symbol that tells you that you're looking at Jupiter, the fifth planet from our sun is the giant red spot
whirling about on it. Any person with the love
of space can tell you that you're actually seeing a
colossal hurricane-like storm that's the size of three Earths but if you ask an astronomer
why the spot is red at all they can only speculate
as nobody actually knows. The red spot storm has been raging for at least 400 years. It's higher up than any of
the clouds surrounding it and is actually cooler in
temperature, not warmer yet still, the only variation in color is a change in hue that occurs on occasion from the recognizable
bright red to a rosy pink. On top of all of this, we still don't know even why this storm is happening at all. Number six are cataclysmic variables. Cataclysmic variables or CVs are binary star systems meaning that there are
two suns instead of one. Having two is actually not that rare as over 50% of the system's discovery have more than one star but for CVs, while one sun
has become a white dwarf which our own sun will do in about four and a half billion years, exhausting its nuclear fuel and becoming extremely dense, its companion sits in
such close proximity to it that the white dwarf literally
drains all of its gas. Now, what doesn't make sense here is that if the primary star
has become a white dwarf, it must have been a red giant previously, meaning the partner star
being as close as it is must have been somehow inside of it. This is absolutely unexplainable and to this day boggles
many scientists' minds. Number five is dark matter. According to the Standard
Model of Cosmology, the universe is made
up of only 4.9% matter, 68.3% is made up of dark energy which we'll get to in a moment but what about the remaining almost 27%? That is where the dark
matter theory comes in. As the name suggests, dark matter is dark as in it cannot be seen. Shockingly, scientists actually know more about what it is not than what it is. It doesn't interact with or
omit electromagnet radiation and we know that it can't be matter as if it was it would contain
particles called baryons which we'd be able to detect
it through reflected light. Still, it exists and
it's out there affecting every galaxy's mass and rotation rate. We simply have no idea what it is. Number four is the great attractor. Our galaxy shouldn't actually
be moving as fast as it is unless of course it's
being drawn to something. Scientists believe that that something is the great attractor, a gravitational anomaly
located at the center of the Laniakea Supercluster that could be thousands
of times more massive than our own galaxy. Numerous tests trying to determine both if the great attractor exists and if so, what it is have been conducted and though we still have
no answers either for or against its existence, a large number of new galaxies
we weren't able to see before have now been discovered. The odds are extremely good. It won't be something that we or our near future ancestors
will have to worry about but just think about this for a second. We have no idea what we're headed for but whatever it is, it
is most likely not good. Number three is the cosmic void. One of the the most bizarre things out there in space is actually
a severe lack of things. The great void is a colossal area of space with very few galaxies. Located within the
constellation Canes Venatici this black spot in the sky is roughly between one billion
and 1.3 billion light years in diameter and yet it's only the second biggest void out there. A 1.8 billion light
year-wide super void exists in a place that is for a reason that scientists cannot determine
colder than it should be. The voids have around 20%
less matter than they should based on the galaxies that surround them. There's one theory that suggests that shortly after the Big Bang, quantum fluctuations
helped redirect matter as the universe expanded so
the voids could be getting even bigger as time goes on. Whatever theory you
choose for this mystery, it still remains completely unknown. Number two is Planet X. While it hasn't been discovered yet, many experts claim the only explanation for the odd orbital behaviors of objects spotted far beyond Neptune, the farthest planet from
our sun in the solar system is the existence of a plant
that for one reason or another we've never seen before. Also known as Planet Nine, Planet X won't have an official name until someone can prove
without a shadow of a doubt that it's actually there. Researchers studying the Kuiper Belt, a ring-shaped group of dwarf planets, frozen gases and other space debris reported that items had a peculiar orbit which could be explained by the existence of a planet roughly the size or Uranus but so far from us that it would take between 10,000 and 20,000
years for it to orbit our sun. NASA's hopeful that we'll be able to prove its existence in our lifetime. And number one is dark energy. Though in a humorous way it kind sounds like a power that a super villain would want to harness, dark energy is actually the stuff that makes up nearly 68% of the universe. The top scientists at NASA cannot tell you exactly what dark energy even is. Theoretically speaking,
it's a repulsive force that is accelerating the
expansion of the universe by counteracting the gravity that would otherwise be slowing it down or even reversing it. There is a theory that there may be a type of energy fluid out there
somewhere filling space or perhaps Einstein's Theory of Gravity should include a cosmological constant or maybe it's wrong altogether. Whatever the real answer is for now, it's been given the label of dark energy until we know something for sure. We also don't know how it
would affect us directly if we ever came into contact with it. Let's hope it doesn't harm us. Thank you very much for watching but we're not done yet.
