Why will a big reflector make more distant stars easier to see?

Unfortunately, no matter how large of a telescope you have, stars will always appear as pinpoints of light. Even the largest professional telescopes are not able to resolve stars as discs. However, if it's a dim star that one is trying to detect, it is true that a telescope with a larger diameter main objective (a mirror in the case of a reflector or a lens in the case of a refractor) will produce a brighter image of the star than one with a smaller main objective. Larger lenses and mirrors gather more light. The light-gathering ability of a telescope depends on the area of its main objective. Since the area of a circular objective varies as the radius squared (area = pi * radius^2), doubling the radius of the objective will quadruple the area of the objective, and therefore the light-gathering ability.

Are Stars cold and make light?
Stars make their own light, but they are not cold. Stars are extremely hot. We do not feel their heat because they are incredibly distant.
Does the medium of space make distance stars appear to be more red shifted only because they are farther away?
Distant stars appear red shifted because they are travelling away from Earth. It just happens that more distant stars are moving faster, so there is a greater red-shift the further a star is from the Earth.
Is the stars that make up a constellation are near each other?
Not necessarily. Stars within a constellation are the same general direction from Earth, but one may be much more distant than the other.

Why are stars distant from one another?
Actually the typical distances between stars vary a lot. Inside a globular cluster, you can have a million stars or so, which are much closer together than in our region.If you ask "Why are they distant from one another in our region of the galaxy", I would say that that can POSSIBLY be answered by the anthropic principle: if stars are much closer together, the conditions MIGHT be catastrophic, and make it difficult for life to survive.
What game can you get the most stars from in Innerstar University?
you can get the most stars at the higher levels at any game. Its easier to get more stars at games your good at. Also, cupcake crazy does not give more stars for the more cupcakes you make. It is only 5 stars each cupcake unless you make them repitively.
How does a periscope make light turn corners?
The periscope has a reflector to make the light turn corners
What would make a better reflector a piece of metal or a piece of wood?
Metal
What is echo time?
It could either be the time of travel of echo from reflector to source, or the round-trip from source to reflector and back to source - you'd have to make clear which in the context you are describing.
Why you can not differentiate between near and distant Star by naked eyes?
You have two eyes, away from each by about 6 cm. The object placed nearby makes a larger angle to both eyes as compared to distant object. From that angle, you make out the distance of the object from you. Stars are too far away for human eyes (or any animal eyes, for that purpose.) to make smaller or bigger angle. They all make the smallest possible angle witch can be recognized by naked eyes and so you can not differentiate between near or distant star. All of them are distant objects for human eyes.
How does dividing the sky into constellations make studying the stars easier?
Recognising constellations makes it easier to work out which stars are which - if you know that Rigel, for example, is in Orion, then it is easier to spot Orion than it is to spot Rigel without looking for Orion, as the constellation is bigger and more easy to recognise than the pin-prick in the sky which is the star you're trying to find.
How is a bicycle reflector helpful?
Not all of them are. Usually there's a white reflector aimed forward, yellow/orange ones aimed sideways and a red one aimed backwards. The different colors are used to make it possible to see from the reflection only which direction the bike is pointing/heading.
