Why is the Universe the size of what it is?
How big is a human relative to the size of the known universe? What is the relation between Pi and size of the Universe? What is bigger, a universe or galaxy? Is there anything bigger than the universe? What is the Big Bang? What is the difference between universe and dimension? How big is the planet? How many dimensions are reported to be existing in our Universe? How do scientists calculate the diameter of galaxies? If everything in the universe doubled in size overnight, would one be able to figure it out? What exactly does it mean when you say the universe is "expanding"? Does the planck-length get bigger? How can there be more space between objects? Why is the rate of expansion of the universe increasing? Since the Big Bang, has the amount of mass in the universe been increasing? Is the amount of energy in the universe decreasing? How many dimensions is space? Has the total mass and energy of the universe remained the same since the Big Bang? Could the acceleration of the expansion of the Universe come from the fact that density is what is hindering creation of space? What are the dimensions of space time? Moments after the Big Bang all the mass of the universe was confined in a tiny radius. Why didn't it collapse to a black hole? What if the universe isn't expanding but matter is all shrinking? What are the proofs of scientists that the universe is expanding? Is the Big Bang really the the origin of our universe? Does the universe have an edge? Does the universe have a limit to its expansion? If so, what happens when the universe reaches its limit? Does size of matter affect gravity? What is an explanation of the Big Bang theory? How many dimensions are there in space? What is the origin of the universe? Does the big bang theory really explain it? Where is the origin point of the big bang in space? And how far are we from there? How did Edwin Hubble know the Universe was expanding when we can only detect a small sector of the Universe? How was matter created when the Big Bang occurred? Is our universe expanding?
