2. Gravity does not have a speed, gravity is a force that results from the curvature of spacetime

So, if a mass suddenly appeared , how lonh would it take for a body at a distnce from that mass to be subject to the gravitatioanl field the 'new' mass created?

The impact of the new mass on space-time propagates at the cosmic speed limit (also the speed of light).

Isn't it time for *someone* to say "big bang bollocks" yet?

I dont think anyone knows much about space at all, let alone how it was created.

There was an interesting Horizon programme on a few weeks back which suggested just that. 😀

looks you have told some tall tales on here but there was never a horizon programme about your trolling 😉

SBZ does have a point though. The origin of the low entropy, organised early universe is one of the big questions in science.

This is where valid theory can stray across into conjecture and leave scientists that are not careful in how they present such discussions open to trolling, naysayers and sensationalism.

Cheers...

Right boys and girls.

1. The speed of light is constant [b]in a vacuum[/b]
