Give some scientific detail why this is.

Because light needs something to reflect off of for you to see it. Space doesn't reflect sunlight the spacecraft does though.

The sky is blue because of Rayleigh scattering. This means that the atmosphere scatters light all over the place but it scatters blue light more than red. That's why sunsets are red; when you take blue light away the sun appears red, and when it's low in the sky there's more scattering because the light goes through more atmosphere. When you're above the atmosphere, in space, there's no air to scatter the light, so you see the sun and stars against a black backdrop of space.If you climb into space in a rocket, the blue sky gradually gets darker until, by the time you've reached about 50 km. it appears black. If you get to ride in an aircraft at about 40 000 feet, which is normal cruising altitude for a passenger jet, the sky will appear dark blue.

We know there is sunlight either from looking at the sun or seeing the light reflected by a wall or the moon, Since space is a vacuum, there's nothing for the light to reflect off so it simply looks black.

Light needs to interact with matter in order to for it to be reflected back to our eyes.
There's nothing for light to bounce off, until it hits an object, like a planet or moon, or anything on planet earth.
The only reason you see light beams down here is because the air is mucky or has lots of moisture.

Because there is no atmosphere in space to refract the sunlight.
Our sky is blue because the sunlight is refracted in our atmosphere. The human eye can only percieve the blue part of this spectrum.

No. memory on a USB stick is on a custom circuit board with custom memory modules and memory controller. there is not any longer thanks to move area for storing from one to a unique,only purchase yet another 8GB stick off of Amazon (no longer Ebay, many sellers promote pretend USB memory sticks)

if the sun can be seen it is not pitch black
