98% of all the earths matter was created in 3 minutes afterthe big bang? in the rest of the 6 billion years or so the other 2% was created.

And what about...
If the universe was scaled down so it became a room 30km by 30km then on the same scale all the planets, stars, asteroids e.t.c. would fit into a grain of sand.

Finally...

The universe is about 1⁴³ light years across (1 followed by 43 zeros or 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000

In other words it would take light that many years to cross it. At any rate it is impossible to reach the edge of the universe because the universe kind of bends reality, you would end up going in circles even if you were actually going in a straight line. That makes a lot of sense doesnt it?
