I assume that with "pace" you mean "speed". The speed depends what you measure it against; for example, Earth moves at a speed of 30 km/second around the Sun, but the numbers vary if you determine the speed around the center of the Milky Way, around the center of mass of the Local Group, or compared to the background radiation.
What else can I help you with?
If the universe expands would the earths gravity decrease?
no
How many Earths can fit into the known universe?
The answer is not determinable both because scientists have not determined the exact volume of the universe and because the universe is always expanding.
What are some of earths features?
It's flat. It is the center of the Universe.
The sky is what?
The sky is the atmosphere of Earth and any visible part of the universe, as observed from Earths surface.
Can a Boeing 747 fly into a black hole at the edge of your universe?
No. It cannot escape the Earths gravity.
Is the entire universe called earths?
No, the term "Earth" specifically refers to the planet we live on. The universe is the vast expanse of all known and unknown matter, energy, space, and time.
The most abundant inert gas is what?
Argon, in the earths atmoshere Helium in the universe Argon in the earths atmoshere Helium in the universe
There are other earths in this universe?
None that we are aware of, yet. However, the universe is enormously, incomprehensibly large, and it is - remotely! - possible that another planet very similar to Earth might exist elsewhere.
How many planet earths makes a sun?
The sun could fit over 1.3 million earths inside of it. Wow... see https://fretzreview.wikispaces.com/Milky+Way,+Universe,+Light+Years
What is the impact of repulsive gravity on the expansion of the universe?
Repulsive gravity, also known as dark energy, is believed to be causing the accelerated expansion of the universe. This means that galaxies are moving away from each other at an increasing rate. The impact of repulsive gravity is that it counteracts the attractive force of gravity, leading to the expansion of the universe at a faster pace.
Is the earths age 54 billion years?
No. The universe itself is "only" about 13.7 billion years old. Earth is about 4.55 billion years old.
Why does not the earth float off into the universe?
because the earths orbit path around the sun keeps up in place. kinda like gravity :) / it is gravity -.-
