云知道


However,according to a widely accepted theory,the universe began with a “Big Bang” that threw matter in all directions.
The problem was that the earth became violent because it was not clear whether the solid shape was to last or not.
It exploded loudly with fire and rock,which were in time to produce carbon,nitrogen water vapour,and other gases,which were to make the earth’s atmosphere.
What many scientists believe is that the continued presence of water allowed the earth to dissolve harmful gases and acids into the oceans and seas.
So whether life will continue on the earth for millions of years to come will depend on whether this problem can be solved.
When we get closer to the moon,we shall feel its gravity pulling us but it will not be as strong a pull as the earth’s.
I found I was carried twice as far as on the earth and fell over.
We watched,amazed as fire broke out on the outside of the spaceship as the earth’s gravity increased.
