Mysteries of the universe

Fermi bubbles, antimatter

Fermi bubbles are giant features of a galaxy, including our own galaxy, that stretch for roughly 35,000 light years, about half the diameter of the Milky Way. What makes them extremely interesting is that they emit gamma rays, the most dangerous form of radiation. The edge of the bubbles emit the most energetic gamma rays. You may ponder this question: could this be a key to the mystery of dark matter? Interesting how gravitational lensing is round. Another fascinating aspect of the universe is named the Fermi Paradox.

Antimatter presents an intriguing scientific mystery. As it turns out, the amount of matter and antimatter in the universe should've been equal, cancelling out each other. However, this was not the case and significant amount of matter remained. Antimatter is the opposite of matter. As it turns out, it's been theorized by engineers that antimatter may someday be harnessed for space travel. If it were true, then this form of energy would allow a spaceship to travel to Mars in five days. Antimatter contains an enormous amount of energy. Just one tenth of a gram could likely cause as much destruction as an apocalyptic, if not, near apocalyptic, asteroid. Scientists have so far been able to make anti-hydrogen, which has been found to destroy hydrogen. The problem with antimatter as a fuel source is that it takes enormous amounts of energy to produce. It is estimated that to produce approximately 1 gram of it, it would take thousands of years of electricity production to go into the process. In fact, it may even take over a million years just to obtain that much antimatter. Then again, such a small amount would contain an enormous amount of energy. Until quite recently, a new form of antimatter has been discovered in near Earth orbit by ISS astronauts. This form of antimatter is called a positron, the antimatter equivalent of an electron. It is thought that the antimatter belt surrounding Earth can be used as a fuel source. One particle of say, anti-helium, would likely be able to destroy many millions of helium atoms, kind of like aerosols destroy ozone. Since matter still remains in the universe, it seems as though there is more than there is antimatter. The reason for this remains unclear. Perhaps there is a mysterious, yet misunderstood, relationship between antimatter & dark energy or antimatter & dark matter.
