I'm pretty sure that the definition of virginity is different for different people. My girlfriend has given me numerous blowjobs and I've fingered her many times, but I'd still consider us both virgins because we've never had sexual intercourse.

Some people may consider that what we've done would make us no long virgins, but there is no real definition of "virgin". The most broad and widely accepted one is

did you put your dick in her pussy? Then yeah you're no longer virgins.

It is OP's opinion that if you put your dick in her pussy and you've got a condom on, it doesn't constitute losing your virginity. The reason why this has caused such a scandal in this thread is because this opinion is contrary to what most people believe. Which is that sexual intercourse with a condom on would constitute losing one's virginity.

Basically, you've all been trolled.

If we apply this concept to a star, we see that the amount of energy in every "sphere" formed by the star's light remains roughly equal. Obviously there are fluctuations in the amount of power put out by a star and the evenness of the sphere will fluctuate as well, but its a rough sphere. As this sphere gets larger, there will be less and less energy per unit area on the sphere, just like with the explosion. If you were to imagine yourself a point on the edge of the sphere and the star at the center, the radius would be the distance from the star to yourself. Because stars are very very very far away, the sphere at your radius would be very very large. All of the original energy has to be spread across all of this area, and thus is greatly diminished.

The human eye has a threshold for how dim an object can be before it disappears from view. There are a lot of stars that are very very far away that we cannot see with the naked eye because we cannot detect them due to their very low relative magnitude, or brightness from our point of view.

This is a completely uneducated explanation that I came up with for myself the other day while thinking about what tiny bits I remembered from sound intensity in my physics courses.

Why space and time, rather than just space? Einstein realized that your motion in the everyday three dimensions of space (up-down, left0right, and back0-front) also affects your motion through the fourth dimension, TIME. For instance, if you move very, very fast in space, your wristwatch will tick very, very slowly with respect to your clock back on Earth. Though space and time have slightly different mathematical properties (our four-dimensional universe has three "space like" dimension and on that is "time like"_ and they are inseparable. Affect space and you automatically affect time, and vice verse. So in a MATHEMATICAL SENSE they are woven together.
