Spell and Trap cards with field or blanket effects (destroy all monsters, switch all monsters to defence mode) will affect all monsters regardless of ownership, unless stated otherwise. Cards like Swords of Revealing Light only affects the opponent's monsters, because it says so. Gravity Bind on the other hand affects all Lv4 or higher monsters, regardless of who controls them.
Seal of Orichalcos' effects only apply to the player who controls it.
Your only opponent is yourself.
It is oddly worded if you think about it, but it does gain ATK for dragons in both the opponent's graveyard and their side of the field. I think the 'each' part is more important, the phrase could be worded as "For dragons that are on the opponent's field, or in the opponent's graveyard, this card gains 500ATK for each".
Only your opponent can equip Horn of Light to one of your own monsters, and I'm not sure why he/she would. Also, only your opponent can use its effect to pay life points to place it on the top of the deck. The only way you could get your opponent's Horn of Light in your hand is with hand-exchanging cards like Exchange; however these cards are not used frequently.
No, "Obelisk the Tormentor" is not affected by "Gravity Bind" because it is an Effect Monster with no Level, and "Gravity Bind" only affects monsters with Levels 4 and higher.

No, Tyrant Dragon's protective effect can only be used against traps that Target it. A Targeted trap is one where a specific monster is picked when the trap card is activated. Gravity Bind selects nothing, it just applies a 'blanket' effect that affects any appropriate card. This is not targeting, so Tyrant Dragon's effect does nothing to it.
The only identical feature shared by gravity and mass is the letter 'a' . The only other possible respect in which they are at all similar is the fact that they both arise during the discussion of the law and effects of gravity.
No, compounds consisting only of a chromophore are not considered stains. Stains typically consist of both a chromophore (which provides color) and an auxochrome (which helps the dye bind to the material being colored). The auxochrome is necessary for the stain to effectively bind to the material and impart color.
They're not. * Earth has a gravity of 9.780327 m/s2 * Mars has a gravity of 3.69 m/s² They're similar in that they both obey the Law of Universal Gravitation, but as you can see the gravity of Mars is only about a third that of Earth.
An object is in free fall only if its motion is subject to being both only affected by gravity and only moving up or down.
The activation site of an enzyme can only bind to a specific substrate.
Mercury & Mars both have surface gravity less than that of Earth. Mars is about 1/3 that of Earth. The surface gravity of Venus is also less, but only very slightly.
The acceleration due to gravity is the same for both objects because it depends only on the mass of the Earth and the distance from its center. While the brick has a greater mass, the force of gravity acting on it is also greater to account for this, resulting in the same acceleration for both objects.
If you only have 6 checker peices left and the opponent has not moved their backrow yet then you win
