  • CF has always been a site that welcomes people from different backgrounds and beliefs to participate in discussion and even debate. That is the nature of its ministry. In view of recent events emotions are running very high. We need to remind people of some basic principles in debating on this site. We need to be civil when we express differences in opinion. No personal attacks. Avoid you, your statements. Don't characterize an entire political party with comparisons to Fascism or Communism or other extreme movements that committed atrocities. CF is not the place for broad brush or blanket statements about groups and political parties. Put the broad brushes and blankets away when you come to CF, better yet, put them in the incinerator. Debate had no place for them. We need to remember that people that commit acts of violence represent themselves or a small extreme faction.

Can light increase its speed within a vacuum?

The reason why creationists do not believe in a big bang is because light cannot accelerate in a vacuum.
And what this means is that all matter was never compressed into a singularity only to explode in a huge burst of energy causing rapid expansion across the universe, not only because the light escaping from the explosion cannot accelerate.

But also because a singularity in space cannot be achieved as the amount of pressure that is exerting outwardly is thousands of times greater than the pressure forcing the matter into an infinitesimal region, just as a glass of water cannot be compressed into a droplet. So the probability of a singularity forming within an infinitesimal region that exploded rapidly across the universe is nil.

Does light change in a vacuum?
Light, no matter how high-or-low in energy, always moves at the speed of light, so long as it's traveling through the vacuum of empty space. Nothing you do to your own motion or to the light's motion will change that speed.

Why is the speed of light in a vacuum constant?
The special principle of relativity: physical laws should have the same form in all inertial systems (systems at constant speed). The speed of light (in a vacuum) is constant for every observer, independent of the movement of the light's sources.
