Light moves slower than I thought. Eh herm. Anyways.
One of my friends had once asked my, "Why do we know more about space than the Ocean? Isn't it kind of weird that we know more about space which is millions of miles away, than the ocean floor?" So I did a bit of research, and this is what I came up with:
Your assertion is not supportable. True we don't know what's really going on in the Marianna's Trench, for example, but then we don't know much about what's going on with poor Pluto either. And to a point, 15 billion light years of space has to hold more unknowns than the few hundred thousand cubic miles of our oceans.
By the way, you totally underestimate the size of space when saying "millions of miles." One light year is 6 trillion miles or so. Thus, 15 billion light years, the radius of our known universe, is 90 billion trillion miles. That's 90 X 10^21 miles or 90,000,000,000,000,000,000,000 miles in radius; double that for the diameter.
Nope, I really think we know far less about the vastness of space than about our oceans.
I know this is kinda off topic but its also kinda related, no?
The dwarf planet of Pluto is about 4.4 (when nearest) to 7.4 (when furthest) kilometers away from our sun, which means that it gets the least amount of sunlight and, as a result, lacks the atmosphere that other planets have. This means that, although sunlight can come in easily, it can leave even more so. The atmosphere is probably mostly made up of nitrogen with some methane and carbon monoxide. However, these are only gases when Pluto is at its nearest to the sun. Most of the rest of the year, the atmosphere is frozen.
The minimum temperature is 38 Kelvin (-391 degrees Fahrenheit), while the maximum temperature is 63 K (-346 °F), so Pluto is covered in icy patches. These icy patches reflect sunlight back towards the sun, which means that Pluto has even less warmth on it.
