Our universe is full of mysteries and miracles, we don't know why, where, how anything exactly about this universe. Here is the some interesting mysteries of the universe.

1.The Theory of Everything.
A theory of everything (TOE) is a hypothetical framework explaining all known physical phenomena in the universe. Researchers have searched for such a model ever since the development of quantum mechanics and Albert Einstein's theory of relativity in the early 20th century.
Each of these pillars of modern physics describes its respective area of inquiry — the very smallest and the most massive things in the cosmos — with astounding accuracy, but both quantum mechanics and relativity fail when applied to each other's subject matter. So far, an overarching theory of everything has eluded scientists, and some believe the ultimate goal is unrealistic.

2.Dark Matter Problem
The evidence that dark matter is real is all but irrefutable. But that only makes it more maddening that we can’t see it. How to measure something so hard to detect? Katie Mack explains.
Evidently, about 84 percent of the matter in the universe does not absorb or emit light. "Dark matter," as it is called, cannot be seen directly, and it hasn't yet been detected by indirect means, either. Instead, dark matter's existence and properties are inferred from its gravitational effects on visible matter, radiation and the structure of the universe. This shadowy substance is thought to pervade the outskirts of galaxies, and may be composed of "weakly interacting massive particles," or WIMPs. Worldwide, there are several detectors on the lookout for WIMPs, but so far, not one has been found. One recent study suggests dark mater might form long, fine-grained streams throughout the universe, and that such streams might radiate out from Earth like hairs.

4.Proton Decay
In particle physics, proton decay is a hypothetical form of particle decay in which the proton decays into lighter subatomic particles, such as a neutral pion and a positron.The proton decay hypothesis was first formulated by Andrei Sakharov in 1967. Despite significant experimental effort, proton decay has never been observed. If it does decay via a positron, the proton's half-life is constrained to be at least 1.67×10^34 years.
5.High Temperature Super conductivity.
This is in fact the lowest temperature reachable by liquid nitrogen, one of the simplest coolant in cryogenics.All superconducting materials known at ordinary pressures currently work far below ambient temperatures and therefore require cooling. The majority of high-temperature superconductors are ceramics materials. On the other hand, Metallic superconductors usually work below -200 °C: they are then called low-temperature superconductors. Metallic superconductors are also ordinary superconductors, since they were discovered and used before the high-temperature ones.
Ceramic superconductors are now becoming suitable for some practical use, but they still have many manufacturing issues and there are very few successful practical examples of employment. Most ceramics are brittle which makes the fabrication of wires from them very problematic.

6.Solar Corona Heating problem.
Imagine standing around a roaring campfire, roasting s’mores. You feel the warmth of the flames as the marshmallows crackle. Now back away. You get cooler, right?
That's not how it works on the sun. The visible surface of the sun has a temperature of 10,000° F. Backing away from the inferno should cool things down, but it doesn’t. Instead, the sun's upper atmosphere, or corona, sizzles at millions of degrees - a temperature 200 to 500 times higher than that of the roaring furnace below.

7. The Higher Dimensions
Some believe this universe is a 3 dimensional one and others and according to relativity theory it may be 4 dimensions 3 spacial and a time according to super string theory it may about 10/11 dimensions actually what is true?
8.The Fate of Universe.
The fate of the universe strongly depends on a factor of unknown value: Ω, a measure of the density of matter and energy throughout the cosmos. If Ω is greater than 1, then space-time would be "closed" like the surface of an enormous sphere. If there is no dark energy, such a universe would eventually stop expanding and would instead start contracting, eventually collapsing in on itself in an event dubbed the "Big Crunch." If the universe is closed but there is dark energy, the spherical universe would expand forever.
Alternatively, if Ω is less than 1, then the geometry of space would be "open" like the surface of a saddle. In this case, its ultimate fate is the "Big Freeze" followed by the "Big Rip": first, the universe's outward acceleration would tear galaxies and stars apart, leaving all matter frigid and alone. Next, the acceleration would grow so strong that it would overwhelm the effects of the forces that hold atoms together, and everything would be wrenched apart.
If Ω = 1, the universe would be flat, extending like an infinite plane in all directions. If there is no dark energy, such a planar universe would expand forever but at a continually decelerating rate, approaching a standstill. If there is dark energy, the flat universe ultimately would experience runaway expansion leading to the Big Rip. Regardless how it plays out, the universe is dying, a fact discussed in detail by astrophysicist Paul Sutter in the essay from December, 2015.
9.The Direction of Time
Time moves forward because a property of the universe called "entropy," roughly defined as the level of disorder, only increases, and so there is no way to reverse a rise in entropy after it has occurred. The fact that entropy increases is a matter of logic: There are more disordered arrangements of particles than there are ordered arrangements, and so as things change, they tend to fall into disarray. But the underlying question here is, why was entropy so low in the past? Put differently, why was the universe so ordered at its beginning, when a huge amount of energy was crammed together in a small amount of space?
10.Wormhole
A wormhole (or Einstein–Rosen bridge or Einstein–Rosen wormhole) is a speculative structure linking disparate points in spacetime, and is based on a special solution of the Einstein field equations. A wormhole can be visualized as a tunnel with two ends at separate points in spacetime (i.e., different locations, or different points in time, or both.)
Wormholes are consistent with the general theory of relativity, but whether wormholes actually exist remains to be seen. Many scientists postulate wormholes are merely a projection of the 4th dimension, analogous to how a 2D being could experience only part of a 3D object.A wormhole could connect extremely long distances such as a billion light years or more, short distances such as a few meters, different universes, or different points in time.
