Every instant is 'forever' for having been at all.
The size of an idea bears no relationship to the time given thinking of it. So that is one instant that has been fairly constant in its cause and effect ever since. A couple of years ago, scientists managed to achieve star heat of 15 million degrees for a billionth of a second with lasers. It was over in a flash but will for ever remain as a high point of achievement. Photographs are a recognition that we can capture an instant of time and freeze it.
