How big is the solar system compared to the universe?

It is impossible to answer. The visible Universe is about 13.7 billion light years across and getting larger with every year. The Solar System is a mere 2 light years at most, a mere 6'850'000'000 of that number.


How old is Earth in comparison to the age of the universe?

Well, my friend, Earth is like a tiny speck of paint on a grand cosmic canvas. Can you believe that Earth is just about 4.5 billion years old while the universe itself is estimated to be around 13.8 billion years old? That's a lot of happy little accidents happening over a lot of time!


When did universe begin where is the end?

We have no way of knowing the answer. Will the universe ever end at all? Again, we don't know. Right now, we suspect that the universe may expand forever; we cannot "see" enough mass to cause the expansion to slow down. But then, we can't see enough mass to keep the Milky Way together; it is spinning entirely too quickly for the mass that we know about to generate enough gravity. Some scientists have postulated some form of "dark matter", and perhaps even a corollary "dark energy" to account for the mass we cannot see. If there is enough (and if it exists at all!) then the universe may, perhaps, slow its expansion and collapse into itself, at some unimaginably distant date in the future. But we're guessing, and scientists try not to guess. Much.

Why is the earth tilted at the north star?

It is mere coincidence that Earth's axis is aligned with Polaris. There are about 5,000 stars visible to the naked eye, so it is not all that unlikely.

Why can't we say that the universe is the result of mere chance?

We can not say that the universe is a result of mere chance because everything has a maker. For example, a computer was made by some one; a car was made by some one, same way this universe with all its sight and wonders and treasures was created by the All-Wise, All-Knowing, and the Most Powerful, Allah.
