Are objects in the universe all travelling outwards towards the edge of the universe?

All object are traveling in different direction and speed. If you believe that the universe has edge, then all direction will point to that edge. Unfortunately, no one can really tell if the universe has edge.

What pulls all objects in the universe including the moon and earth and the sun and earth towards each other?
gravity
What does the Doppler effect tell scientists about the universe?
The Doppler effect causes objects that are moving towards an observer to increase in frequency while those that move away from an observer decrease in frequency. In 1920s and 1930s, Edward Hubble was measuring the Doppler shift of various stars in the night sky, and discovered that there were fa more shifted towards the red spectrum (lower frequency) then the blue spectrum (higher frequency). Hubble concluded from this fact that the universe is constantly expanding outwards, and formulated Hubbles Law to approcimate the rate of universal expansion.
Which is the most accurate description of gravity?
A natural force of attraction exerted by the Earth upon objects that pulls the objects towards Earth's center
Why is the light reaching us from celestial objects shifted towards the red or blue end of the spectrum?
Due to something similar to the Doppler effect. A wave reaching us from an object travelling towards us will look shorter than the same wave from an object travelling away from us. In light shorter waves gets bluer end longer waves get redder.
Why is there a shiny surface at the back of the radiator?
The shiny surface is a reflector, to reflect the heat outwards towards you.
Do light waves travel towards or away when travelling through a slower medium?
towards the normal
Why is the light reaching us from some celestial objects shifted towards the red or blue end of the spectrum?
Due to something similar to the Doppler effect. A wave reaching us from an object travelling towards us will look shorter than the same wave from an object travelling away from us. In light shorter waves gets bluer end longer waves get redder.
How do red shifts were used by cosmologists to determine that the universe is expanding?
A Galaxy's red-shift can be used to determine how fast it is travelling away from you. The opposite is "blue-shift" which is what happens when the Galaxy is travelling towards you.The first astronomers, such as Edwin Hubble, to analyse the light coming from distant galaxies discovered that almost all of them were red-shifted, indicating that they were almost all heading away from us. This was the first indication that the universe was expanding.
What is a force that pulls objects towards other objects?
Gravity
Scientists' evidence for an expanding universe is called a because the light waves emitted by stars and galaxies are shifting toward the end of the visible color spectrum.?
Many objects observed in the universe show a red shift. It is believed that this red shift is caused by a Doppler effect - that is, that the objects are moving away from us at a significant fraction of the speed of light. If this is true, then it is evidence for an expanding universe.
How gravity does effects objects?
Gravity pulls objects towards Earth. Or, in more general terms, towards any mass.
What was Aristotle's theory about gravity?
Aristotle did not have a specific theory of gravity as we understand it today. He believed in the natural motion of objects toward their natural place in the universe (e.g., heavier objects falling towards Earth, and lighter objects rising). His view was different from the modern understanding of gravity as a force of attraction between objects with mass.
