Problem: What is the missing first step of the following process: - The star burns until it runs out of fuel - The star can no longer support its weight - The layers of hydrogen press down on the core - The core gets smaller and smaller under the pressure - The pressure causes gravity to get stronger - The gravity becomes so powerful that nothing can escape it - Anything that gets close to it, is drawn into it by its gravity - Light is drawn into it - Light can not escape -

A: Stars burn mass

Problem: What is the missing first step of the following process: - Your thermostat sends a signal to your heating system to provide heat for your home - When your oil burner is engaged, heating oil travels from the tank to the burner by way of a pump - Here the oil becomes a fine mist mixed with air - The fuel/air mixture is then injected into the burner where it is ignited in the combustion chamber - The warm air is disbursed through vents, hot water through baseboards, or by steam radiators -

A: Your thermostat senses that the room temperature has fallen below your thermostat setting
