Is space all darkness? or does it depend on the direction of the space craft relative to its position to the sun?

Could we send a space probe to our nearest star, Alpha Centauri, that would still have enough power to send back information/pictures when it got there? How fast (as a % of the speed of light) could such a probe travel using existing technology? How many years would elapse from launch to when we got our first pictures back?

- exoplanets similar to Earth? Telluric exoplanets with atmosphere?

- Alright: exoplanets around a single star have been discovered.
But are there also discovered exoplanets in multiple stellar systems? (binary, ternary, ...)

In all the space photos I've seen,space has always been dark...so i would like to know why it is so,even though sunlight passes through it and only then reaches the Earth....

is it too much to ask that they send 100,000,000 of their countrymen with it?

Wouldn't you think we would have gone back by now, tried to build some space stations, study space from there?

Just like the mechanism that keeps planets orbiting the Sun, angular momentum should keep this gas and dust coasting around black holes forever.
However, Could it be true that the reason that black holes are able to achieve this great feat is from the momentum itself left from the implosion? that the particles around it were once a part of the star that created the black hole? Therefore, A black hole can and will only grow to be as big as it once was, when it was a star.
It could be possible that the particles around a black hole are minute compared to the actual size of the existing black hole and therefore were not sucked up by the initial implosion.Newton's 3rd Law explains, the reaction must be equal and opposite the action, but it does not say anything about the method of the reaction, just that it must be equal in the end. This process could take millions of years to complete, and it would be true, right? Then particles sucked into a Black Hole might have once been part of it.

There have been documentaries and other reports that we didnt have the technology to do so. Supposedly, the radiation levels on the moon are too high for humans--even in special space suits.

also include why you would be a good choice for the mission...
and what you would take with you... you are allowed 100lbs of personal property...

the mission is a stright line to the next solar system in our galaxy, with conditions for life, and technology has not advanced farther than today... so it's gonna be a long trip where you great grand kids are the ones who arrive...

The theory needs to allow traveling large distance in short duration
i.e shorter than time taken by light

I read an article about Hawking radiation and black holes some time ago, and I wonder if it is possible that black holes could actually be fueling the ever increasing expansion that we are seeing? My idea is this: That since a black hole has infinite density could that matter actually be pushing through the spacetime fabric and being observed as that apparent matter we see in vacuum. By this I mean the theory that vacuum actually contains billions of subatomic particles that are being created and destroyed every second. And that it is this energy that is accelerating the expansion we are observing.

Look at that picture. Just look at it! Aside from its breathtaking beauty, it is eerily familiar. Does anyone else notice this similarity?

The horse head nebula! I think its painfully obvious how close these resemble eachother, and i'd like to know if there is some kind of reason for this. Sure nebulas are clouds, but then where is the gravitational pull that is helping shape these interstellar clouds? OH what i wouldn't give to see things from a larger scale.
