How would other galaxies appear to move relative to Earth if the universe were shrinking?
If the Universe was shrinking the galaxies would appear to be moving towards the Earth, and look more blue than they should. This is the opposite to the universe expanding where galaxies would appear to be moving away from the Earth, which we know due to "red shift". Andromeda would be the exception since it's directly moving towards the Milky Way.
What does a light year have to do with the sun and the earth?
A "light year" is a measure of distance, derived from "how far light can travel in one Earth year". Thus, if you shine a torch for the amount of time it takes the Earth to orbit the sun exactly once, that light would have travelled the distance of a "light year".
What would happen if the earth was tilted 30 degrees?
If the earth was not tilted at an angle of 23.5 degrees, there would not be the different seasons.
Light takes time to reach earth but according to Einstein it should not right?
No; according to Einstein it should take time for light to reach earth from the sun. Light is not instantaneous. The trip takes about 8 minutes. You may be confusing this with the theoretical result that if you were able to accelerate to the speed of light (you cannot) then for you, time would stop passing. You'd still be traveling at light speed, but you would have no experience of the passage of time. If you attained light speed and maintained it for 1000 years as observed from earth, you would decelerate to find that 1000 years just passed by on earth, as if in an instant, and you would find yourself very, very far from where you were only a moment before (from your point of view). This goes against what our intuition tells us about time; it is a 'relativistic' effect. And by the way, you would not have aged a moment over the thousand earth years you spent at light speed.
If the earth didn't tilt describe how our climate would be different?
we will not have seasons
How small would the Earth appear if it were inside a black hole?
If the Earth were inside a black hole, it would appear much smaller due to the extreme gravitational forces bending light.
How would a three hour time exposure photograph of stars in the northern sky appear if earth did not rotate?
The stars would be brighter points of light. Without the Earth's rotation, the Earth would not be moving enough to create the lines of light that ordinarily appear in an uncorrected stationary time exposure. Depending on the clarity of the sky, the entire image could be grayed by scattered light (light pollution).

Depending on the clarity of the sky, the entire image could be grayed by scattered light (light pollution).
How far is the constellation lynx from earth?
Constellations don't have a particular distance from Earth. This is because the stars only APPEAR to be a group in the sky. In fact they are all at different distances usually.
What colour would a red rose appear under blue light?
A red rose would appear darker and less vibrant under blue light due to the interaction between the blue light and the red pigments in the rose petals. The blue light would not enhance the red color of the rose, making it appear different from how it looks under white light.
What if the sun was blue instead of yellow?
If the sun were blue instead of yellow, it would emit a different color of light and the sky would appear differently. Blue light scatters more easily in the atmosphere, so the sky might appear a different shade of blue during the day. The overall impact on Earth's climate and ecosystems would depend on how the change in sunlight color affects factors like temperature and plant growth.
What is different between earth and sun?
The sun produces natural light and would kill us if we came near it, we would burn. Whereas Earth receives light from the sun.
What if our sun was blue instead of yellow?
If our sun were blue instead of yellow, it would emit a different color of light and appear bluer in the sky. This change in color would affect the way we perceive the world around us, as colors would appear differently under a blue sun. Additionally, the temperature and energy output of the sun would also be different, potentially impacting the climate and conditions on Earth.
What colour would a red flag appear in red light?
A red flag would appear red in red light because the color of an object is determined by the light it reflects. In this case, the red flag would reflect red light, making it appear red.
How would the moon appear to an observe on earth if the moon did not rotate?
it would still appear to rotate
How would the moon appear to an observer on earth if the moon did not rotate?
it would still appear to rotate
What color would a red object appear to be if you shone a green light on it?
it would appear black.
