What is blue shift?
Blue shift is a phenomenon whereby a moving object emits light in such a way that the waves of light actually posses a higher frequency than when emitted. Its like a pitcher throwing a fastball versus the same pitcher throwing a fastball from a moving vehicle; to an observer on the side of the road, the ball has a higher velocity when being thrown from the vehicle than from a stationary pitcher. The higher frequency of the light results in a shift towards the blue-end of the visible light spectrum; hence the name blue shift. This is a method used in astronomy to determine that a visible object is moving towards the Earth.
What shift of color do you receive from stars as you get closer?
Blue shift as you get closer because by the Doppler effect, the frequency of the light increases, so the light seems more blue. Using the same logic, there is a red shift for light as you move away from stars.
What does redshifts indicate to astronomers?
The object is moving away from the observer.
Who discovered the red shift in stars the same effect that causes sound waves to change pitch as an object moves towards or away from an observer?
Doppler.
What type of shift in the spectrum would you expect from a star that was moving in the same direction as earth at the same speed of earth?
You would expect no shift in its spectrum. Any shift one way or the other is the result ofmotion either toward or away from Earth. Motion parallel to ours or across our line of sighthas no effect on the observed spectrum of the object.
Can red shift and blue shift exist on the same object at the same time?
Yes, if the object is spinning there will be red shifts on the half moving away and blue shifts on the half moving closer.This is one way tornadoes are detected using Doppler RADAR, the water droplets on one side of the cloud are moving away (red shift) while those on the other side are moving closer (blue shift), showing that the cloud is rotating.Solid spinning objects act the same and the rotation is detectable with Doppler RADAR.
Can there be purple shift aswell as blue shift and red shift?
Redshift and blueshift refer to a change in frequency of light we receive from distant objects (stars, galaxies, etc.) The light can turn different colors, and purple is one of them. However, no matter what the color the light changes to, the technical term is always "redshift" if the frequency of the light decreases (normally indicating that the object is moving away from us), and "blueshift" if it increases (normally indicating that the object is moving towards us). Blue shift and purple shift would mean the same thing because the spectrum is one-dimensional. It's like if you are in Boston, a shift towards Chicago is the same as a shift towards San Francisco. Obviously, a purple shift is a super blue shift.

What density of the blue object is true?
if this is the same question i had then the answer is -the blue object has a density less than 1g/cm^3
What happens when a juggernaut meets an immovable object?
It is impossible for a juggernaut and an immovable object to exist in the same universe and dimension.

Blue shift as you get closer because by the Doppler effect, the frequency of the light increases, so the light seems more blue. Using the same logic, there is a red shift for light as you move away from stars.
Is there any cheats for superstar racing?
Yes there are ... you see when you pres shift+6 and shift+r u can whrite red letters its the same with blue u just go shift+b :)
How can two different opbjects with different speeds give off the same red shift?
No one ever said that they do. In fact, the only way we know a distant object's [radial] speed is through its red shift. So if two objects have the same red shift, then as far as anybody knows, they have the same speed.
Is the sky blue a hypothesis?
No. The sky is just as blue as a blue shirt though. Technically an object, such as a shirt or the sky, is not blue. The object just appears to be blue because it absorbs all other colors of the spectrum and reflects blue back which is the same with any other color seen.
What does redshifts indicate to astronomers?
The object is moving away from the observer.
Is it possible to assign data from one object of a class to another object of a same class?
Yes. In fact this is precisely why the copy constructor and assignment operator exist.
What scientific principle would have to exist for two objects to fall at the same time if one object has a parachute?
A vacuum.
