First, this would go under physics.
Gravity is a relatively weak force and depends on the mass and distance of two objects. Even between insects, the force of gravity exists. However, it is not strong enough to be present because the two masses are too small and too far away.
Here is a Harvard question that is similar.

If the universe started out so dense, why didn't it collapse into a black hole?
A large enough clump of matter will collapse to form a black hole, but ONLY if it is surrounded by (relatively) empty space. During the Big Bang, there WAS NO empty space: ALL of space was filled more or less uniformly with matter and energy; there was no "center of attraction" around which matter could coalesce. Under these circumstances, a cosmic-scale black hole will not form (and lucky for us!).
Answer:
Charge-charge interactions (salt bridge, ionic bond) are electrostatic interactions between a pair of ions is True.
Explanation:
Electrostatic interaction between pairs of ions involves the transfer of ion/charges from two bonding elements in their ionic state
A weight of an object is a measure of the force exerted on the object by gravity. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.
There are four quantum numbers: the n, l, m and ms. When the orbital is 2p, it means that n=2 and l = 1. The n number takes the whole number before the sub-orbitals. Then, the designation for the p orbital is l=1. Now, the possible values if m is a range from -l to l. H<em>ence, in this case, that would be: -1, 0, 1.</em>
The element first discovered in the sun is the element Helium. This noble gas is the second most abundant element<span> in the universe and was </span>discovered<span> on the </span>sun<span> before it was discovered on the earth. Helium is the result of the nuclear fusion of hydrogen creating thus the mass of energy in the sun.</span>
