The more massive the shorter - down to just millions of years.
The sun is expected to last for another 5 billion years. It is currently in the middle of its main sequence phase, which is the longest phase in its life cycle.
Most stars in the universe are main sequence stars. These stars are in a stable phase of their life cycle where they generate energy through nuclear fusion in their cores. The Sun is a main sequence star.
As long as you summoned it with Monster Reborn in main phase 1, then yes, of course. If you summoned it in main phase 2, you cannot attack because you have already passed the battle phase.
Game phases? If you mean the phases for a turn in Yu-Gi-Oh then here they are: Draw Phase Standby Phase Main Phase 1 Battle Phase Main Phase 2 End Phase
A star with a mass of 2solar masses, 2times the mass of the sun, would have a main-sequence stage of half the life of a star with the mass of our sun. More massive stars die faster, less massive stars live longer and therefore have longer main-sequence stages.
No. The less massive a star, the longer it will last. A main sequence star half the mass of the sun can be expected to last about 5 times longer.
Yes, as long as it is Spell Speed 2 or 3, and Set on the field previously in the case of a Quickplay Spell or Trap card. That means the opponent can potentially do something before you get your first opportunity to activate a spell speed 1 card or perform a summon.
In your own main phase 1 or main phase 2.
their really isn't a big difference between them except for the fact in Main Phase 2 you can't attack again if you are planning on setting Spell [S]/ Trap [T] cards face-up or face-down. what i mean is - Draw Phase - Main Phase 1 - Battle Phase - Main Phase 2 - End Phase during Main Phase 1 you can set your s/t cards and launch you attack in your battle phase. Main Phase 2 if you can set more s/t cards after your done setting the amount you want to set you'll probably have to end your turn.
Yes you can but only if you have not summoned a monster already that turn. You can only summon or set a monster once per turn. You can summon a monster during main phase 1 or main phase 2 Draw phase Standby phase Main phase 1 Battle phase Main phase 2 End phase
A star is generally more stable during its main sequence phase. In this phase, it achieves a balance between the gravitational forces pulling inward and the nuclear fusion reactions pushing outward, allowing for a long, stable period of energy production. In contrast, during the giant phase, the star undergoes significant changes in its core and outer layers, leading to instability and variability in brightness. Thus, the main sequence phase is characterized by a more stable and predictable state.
Not exactly. You can proceed from Main Phase 1 to the End Phase if you don't wish to have a battle phase, that is valid. You will skip the Battle Phase and Main Phase 2. But if you DO have a Battle Phase, then you must also have a Main Phase 2. A turn player can ask the opponent if it's ok to move to the end phase from the battle phase if he doesn't want to use Main Phase 2. That allows the opponent opportunity to say no, if they wished to activate something there. But the phase is not being skipped, in the same sense as the example above.
