Can we really see anything?

We only see the light reflected off of an object.  Google the invisibility cloak that scientists have comeup with.  It works by refracting and redirecting light .

Depends where ur looking.  If you look at the right spot you will see nothing, because there wouldn't be anything obstructing your view.  Or you might see that bird that just crossed your view.

Anything's possible.  This is where Occam's Razor comes in quite handy.

No, but would you really want to see it?

Huge.\n\nThere is an edge to what we are able to see and could ever possibly see in the universe. Light travels at 300,000 kilometers per second. That's top speed in this universe—nothing can go faster—but it's relatively slow compared to the distances to be traveled. The nearest big galaxy to our Milky Way, the Andromeda galaxy, is two million light-years away. The most distant galaxies we can now see are 10 or 12 billion light-years away. We could never see a galaxy that is farther away in light travel time than the universe is old—an estimated 14 billion or so years. Thus, we are surrounded by a "horizon" that we cannot look beyond—a horizon set by the distance that light can travel over the age of the universe. \n\nThis horizon describes the visible universe—a region some 28 billion light years in diameter. But what are the horizons of a civilization that inhabits the most distant galaxies we see? And what about galaxies at the limits of their vision? There is every reason to think that the universe extends a long way beyond the part of the universe we can see. In fact, a variety of observations suggest that our visible patch may be a small fraction—maybe an infinitely small fraction—of the whole universe. \n\nThis view of the universe fits with the currently popular idea that the universe began with a vast expansion of size. The idea describes a kind of undirected energy present in the vacuum of space, called scalar fields, that somehow got channeled into a process called "inflation." By conservative estimates, the universe expanded so much during this period that something the size of an atom inflated to the size of a galaxy. \n\nIf this grand idea is correct, then the universe is larger than we ever could have imagined.\n\netc...

Theoretically, as it is said in the article, it is possible.\n \nLet me explain how we can "see", our eyes have the ability to recognize objects through light. And light, as you already well know I assume, is composed of 7 colors:\nRed\nOrange\nYellow\nGreen\nBlue\nIndigo\nViolet\nIt is known as the ROYGBIV or the spectrum. When light strikes through an object, in this case we will set an example of a blue object, all the other colors are absorbed by the object except for the color blue causing it to strike away to that object. And then it enters our eyes and our brain will interpret is as such.\n\nNow if all of the colors are absorbed, then no light will enter and we see it as black. If all colors are strikes away towards our eyes then wee see it as white. \n\nIt is said in the article that they are gonna use gadgets that will steer light and other forms of electromagnetic radiation AROUND the "cloak" and not to bounce back to our eyes causing it not to have any color at all, not even black nor white. What is that? It is indeed invisible.

You saw WHAT is possible?

We're curious and want what we can't see anytime we'd like.

How would one know if this 'cream' were indeed real, since no one could see it?

Peace on you...Can you prove that you exist? Yes, of course you can. You merely use your senses to determine that you can see, hear, feel, smell, taste and you have emotions as well. All of this is a part of your existence. But this is not how we perceive God in Islam. We can look to the things that He has created and the way that He cares for things and sustains us, to know that there is no doubt of His existence.\n\nThink about this the next time that you are looking up at the moon or the stars on a clear night; could you drop a drinking glass on the sidewalk and expect that it would hit the ground and on impact it would not shatter, but it would divide up into little small drinking glasses, with iced tea in them? Of course not.\n\nAnd then consider if a tornado came through a junkyard and tore through the old cars; would it leave behind a nice new Mercedes with the engine running and no parts left around? Naturally not.\n\nCan a fast food restaurant operate itself without any people there? That's crazy for anyone to even think about.\n\nAfter considering all of the above, how could we look to the universe above us through a telescope or observe the molecules in a microscope and then think that all of this came about as a result of a "big bang" or some "accident?"\n\n(see also "Quran")   May Allah bless us

i dont get your question... why can't we see them?

I can't see it...is it that small?

Definitely! If you know where to look you can see them with the naked eye. Take your scope out in the darkest area you can find.I.E, the country. The easiest ones to find are spirals. They may look a little fuzzy but you should be able to see the spiral.

Sure, ANYTHING is possible.\n\nThe scary thing is we would all probably just go on thinking nothing had happened and not even realize it.

If there was just nothing, we would never know what could happen because we wouldnt exist.\nI believe there is more out there in the universe than what we know of.\nWether we discover these things or not is hard to ever say.
