Unsolved mystery - At some point in our lives we will all share the same thought: is there more out there than we are aware of? And what if everything we knew – our whole universe – was just a speck of dust in comparison to the endless possibilities that remain untouched in outer space? The thoughts are mind-boggling and always lead to more questions: can we really believe that we are alone in this universe? Are the government’s withholding information from us? Are there other realms? Will we ever discover the answers to these mysteries? Here are ten unsolved mysteries and conspiracy theories from outer space.

Multiverse, or meta-universe, is the hypothetical notion of several univeres in space including our own. The term was coined in 1895 by the American philosopher and psychologist William James. The idea is that the multi universes work together to make everything we know exist: the entirety of space and time, all forms of matter, energy and momentum, and the physical laws and constants that govern them. Many scientists dismiss this idea as mere speculation. Humans are unlikely to ever discover whether this is true as they only way to find out would be to travel through the multiple universes.

A study has been conducted into this theory, which began by focusing on quantum teleportation. This is deemed to be successful in relocating the ‘quantum state’ of smaller objects across spatial distances but did not succeed in replicating the original object which was destroyed in the process. This means that the new object at the destination has the ‘quantum state’ or essence of the ‘original object’ but is reconstituted with a new set of atoms, molecules, etc. Q-Teleportation (as it is known) has been successful on smaller objects according to the study.

The colonisation of Mars by humans is a rumour as well as a case of serious study. Why so? Because the surface conditions and availability of water on Mars make it arguably the most hospitable planet in the solar system other than Earth. Conspiracy theorists over the years have long debated that life exists on the planet and that NASA are covering up the truth. A lot of photos have also called into question civilization on Mars, such as the face on Mars, Pyramids on Mars, and even a recent picture of what appears to be an ape like figure sitting on a rock on Mars! While most scientists lambast these pictures as hoaxes others claim that Mars was once attached to Earth and life forms remained on Mars when the two planets seperated.

Dark energy is believed to be the biggest mystery of our universe. In physical cosmology, astronomy and celestial mechanics, dark energy is a hypothetical form of energy that permeates all of space and tends to increase the rate of expansion of the universe. By the law of gravity, large objects, like galaxy clusters, should attract each other, and their gravitational pull should pull in other objects. This however, is not the case, and the fact is most galaxy clusters are moving farther apart. The best explanation for this is dark energy. It is believed that 74% of the total mass-energy of the universe is made up of dark energy. The exact nature of dark energy is speculation but what is known is that it does not interact with any other forces apart from gravity.

Albert Einstein’s equation E = MC^2 is perhaps the best known equation of the century. When this is applied to space though to determine how much matter the universe should have, only 4% of matter is found! So where is the rest of it you ask? In astronomy and cosmology, dark matter is a theoretical form of matter that is undetectable by its emitted radiation, but whose presence can be inferred from gravitational effects on visible matter. Dark matter and dark energy are therefore believed to account for the majority of the mass in the observable universe.

There are many theories behind extraterrestrial life. One such theory is that it may have emerged, independently, from different places in the universe, while an alternative suggestion is panspermia or exogenesis, which means life began in one location and then spread to other habitable planets. Extraterrestrial life has a number of meanings as well; from simple forms of bacteria to sapient beings more advanced than humans. Two of the most original sightings of UFOs came from the 60s; one from an astronaught, Major Gordon Cooper, whose sighting of a solid, glowing, greenish object ahead of him was picked up by the tracking station back on Earth and the second sighting coming from a NASA pilot, Joseph Walker, who filmed five or six UFOs during his record breaking fifty-mile-high flight in April, 1962. NASA never comment though, preferring to brush such occasions under the rug which only adds fuel to the mystery.

Sound waves were detected by Cassini’s radio wave and plasma science instrument (RPWS) on December 8, 2000, at a distance of about 23 million kilometers (14 million miles) from Jupiter. The eerie sounds that were picked up are likely to have derived from an interaction of the magnetic field that surrounds Jupiter and the solar wind of particles speeding away from the Sun. There is speculation that the sounds could be those of exploding stars but this is highly unlikely as dark matter is too dense for sound waves to travel through. Another logical explanation that uncovers the truth or keeps it hidden?

Sergeant Karl Wolfe has explained how he came to bear witness of unidentified shapes which resemble towers and even half-a-mile in size structures on the moon. Whilst in a private area of the Langley Air Force Base a colleague showed him pictures of the moon which revealed a mysterious base as well as the mysterious structures. Before they were to be released to the public though they were to be airbrushed out. Watch the video of Karl Wolfe below to listen to his explanation and see the images that were smudged out by NASA.

Since the turn of the century hundreds of new solar planets have been discovered orbiting distant stars, much like our own sun. Some of these planets are described as Earth-like, such as Gliese 581d, a planet believed to have liquid water on its surface. Because of its mass, which is 7 and 14 times that of Earth’s, it has been categorised as a Super Earth. In late April 2009, new observations by the original discovery team concluded that the planet is within the habitable zone and therefore life could exist. Another theory though says Gliese 581 d is probably too massive to be made only of rocky material, but it is speculated that it is an icy planet that is migrating closer to a dying star making it of no benefit to humans.

Yes its full name is a mouthful and would take a week to pronounce in its entirety so we’ll refer to it as Eagle Nebula as everyone does! The Eagle Nebula is a cluster of stars in the constellation Serpens, which was discovered by Jean-Philippe de Cheseaux in 1745-46. It was given its name because its shape is resemblant to that of an eagle. When this close-up image of the Eagle Nebula star-forming gas and dust pillars was shown to the world on CNN on Thursday November 2 1995 (taken by the Hubble Space Telescope), the phone lines went crazy with hundreds of people claiming to see a face in the star cloud. Scientist have not been able to explain this phenomena. Can you see it?
