10 Theories Why We Haven't Discovered Aliens Yet

10. 4-Dimensional Beings

Picture what a two-dimensional being would be like. It would be flat because it would lack depth. Its surroundings would similarly only be measured by length and width as well. A two-dimensional being would be unable to comprehend or even look upon a three-dimensional being such as humans. Now imagine how a four-dimension being would seem to us with our measly three dimensions.

When a scientist talks about dimensions, they most likely mean a set of numbers by which space is measured. In the case of three dimensions, the measurements length, width, and depth. Scientists are unsure of what the fourth dimension could be, though the most common hypothesis is time, meaning that these theoretical creatures exist out of a linear perception of time.

This theory posits that aliens do exist and may have discovered us, and they might even be more populous than us. They could exist in the same space that people do, but humans aren't able to perceive or understand such a high level being such as that. So, you never have to feel alone. Even when you settle down to sleep tonight, take a look at your empty bedroom, and maybe a 4-D creature is watching you. Sleep tight.
