The sense of smell & others...

Smell is a sense that you're probably most familiar with. Even though it might not be the most used up of all the senses. This is because smell holds a secret in and of itself. Because it can sometimes have the quality of helping to remember memories. Let me go off topic here for a little bit. When it comes to eyesight, colors can combine, creating new ones. And, of course, the reality is that light has many more properties, such as contrast, or values. So, anyways, if we are only able to see a limited amount of colors, then let's ponder something perhaps way more interesting. What about smells? Sounds? Tastes? Could it be that many of the things we hear, for example, don't even "exist", in the same sense that secondary colors don't exist? Well, the thing about human senses is that, each one is different in it's own unique way. Hearing depends on how sound waves behave before, or upon, reaching our ears. So sound is like vision in a way, as sound waves can interact with each other to change the tone of the sound waves. Let's get back to the sense of smell then. Unlike our visual receptors, smell depends on many more sensory receptors, as does taste. However, even though taste and smell receptors are very complex, they still have their limits. If two or more smells were to combine together, you're sensory receptors might fool you into thinking that you're smelling one thing, while you're actually smelling other smells. And it's not totally unlikely that say, a fragrance will combine with an odor, to create another... odor? Or would it now smell like an aromatic fragrance? Or, the third possibility is that you may find yourself indifferent to the smell. So, here's the thing: whenever you're starting to sense something, and you are wondering, "what is that smell?", just remember that you might just be caught up in an "illusion"- not necessarily one that's optical- one that's sensory. It's very likely that with many new tastes, sounds, feelings, and /or smell we will encounter in the future will make us develop new sensory receptors. The interesting thing about some of our senses is that they can't be merely measured by means of comparison. Take smell , for instance. How do we describe an unknown smell to someone? If it were a color, then we could easily just point to a similar color on a color graph. With smell, it's way more difficult. The best we can probably do for now is to come up with a map, in which smells are mapped out, in relation to other smells. Then we can chart that smell by saying that it smells more like this smell than it does another.                                                               

One of the closest planets

Recently, a new planet has been discovered- "only" 39 light years away. Well hey, that's not bad given how far other planets are away from our solar system- not bad at all. However, it's extremely difficult to think of a planet being so far away. Anyways, this planet is estimated to be 1.6 times the mass of our own Earth, and like Earth, is also rocky. However, this is when just about all of the similarities end- especially when we think about it's surface temperature as well as the incredibly close proximity it has to its own star. In fact, it's orbit would fit exactly thirty times inside the orbit of Mercury! Despite the fact that it orbits so close to its parent star, its temperature is not much hotter than that of Mercury. In fact it's about the same. About 450 degrees Fahrenheit. Yes, that's probably too hot for life to exist. I wonder if this world spins? Anyways, it's parent star is significantly smaller than ours, which is probably one of the main reasons for why the temperature doesn't surge that much. They say water couldn't exist... or could it? Well, I'm not sure. However, I think it might be possible that this planet does contain water vapor on its surface. Why? Because although the inner planets of our solar system don't contain water, that doesn't mean that this particular planet has to be the same. Sure, it's truly hot over there. However, if this is a planet that doesn't spin, then this may leave a very slim sliver that exists between the light side and the dark side. You might think that any water wouldn't stay here in this tiny sliver of perhaps habitable area. Perhaps this is so, because as soon as it moved from the dark side to the light side, or vice versa, then this water would either totally evaporate become totally frozen over.
