Why is space expanding?
How is space expanding?
If the universe is expanding then where does the extra space come from? Is there space outside this universe? Does space ever end? Has space have any end? What if the universe isn't expanding but matter is all shrinking? Scientists say that the universe is expanding, and all the galaxies are moving away from one another. How can they be sure that this is due to expansion and not shrinking of all the matter everywhere in the same ratio? Could the acceleration of the expansion of the Universe come from the fact that density is what is hindering creation of space? If the universe is expanding, is there a centre point which remains fixed? If space expands, it releases stored up gravitational potential energy, which converts into the intrinsic energy that fills the newly created volume? Our universe is a sphere, but what direction are we expanding in? Are all galaxies moving away from us or are they moving in some specific direction? What will happen when the universe stops expanding? Does the universe need energy to expand? Will the universe expand forever? What will happen if the universe stopped expanding? Is it possible for us to colonize space? How feasible is space travel? Is space time infinite? Could there be a size limit to the universe's expansion? Is there a limit for the expansion of the Universe? As space expands, it releases stored up gravitational potential energy, which converts into the intrinsic energy that fills the newly created volume? Is universe expanding because there is potential energy that transforms into kinetic energy all the time? Does the universe have a limit to its expansion? If the universe is expanding, why is the Earth moving towards the Sun? What happens if we go up in space? If the universe is expanding when will it exceed the speed of light? Could outer space itself have a space? Atomic structure, the solar system, the Milky Way are all planar, therefore the universe is planar. Anything in motion has one predominant direction and observations indicate universe to be expanding. Is this expansion more flat in nature? Is space divided in 10 dimensions? How? How can we calculate the expanding rate of the universe if it has no center? Is the expansion of the internet much like the expansion of the universe? What is it like in space? Is spacetime a field?
