I would like to chime in on this topic with a very interesting and science based concept, ZPE or Zero Point Energy, it is what is left over in a true vacuum and is everywhere, meaning if you were to make a vacuum in a tube you would remove all gases, solids and liquids, then you would have to drop the temp to remove heat energy to 270c I believe, then you have ZPE meaning when nothing is left there is still something there, what's there is a sea of electromagnetic energy. Hope that makes some sense.
Now that in and of itself isn't new, what has come to light in resent years is that there is more ZPE now than in the past, the reason for that is the expanding universe, just like when you stretch a rubber band you add kinetic energy to it the same thing happens with the universe, as it expands the more ZPE gets added, meaning its growing in power so to speak and has had a profound effect on 3 very important things, first the speed of light, the speed of light is slowing down and is not the constant we thought it was, reason being ZPE.
In the past when ZPE was less light traveled faster because the light was not obstructed by it, you see the ZPE is a sea of electromagnetic energy that produces particles that enter reality for a fraction of a second and then depart, light hits these particles which slows it down very slightly but enough to have an effect, and as ZPE has increased the speed of light has been decreasing.
The second thing ZPE effects is time, if you take one of the main principals for the atomic clock it is based on the rotation of the electrons orbit, that in turn is also impeded by the increased ZPE, so atomic processes are slowed down meaning time moved faster in the past then it does today, which explains why our concept of times past is so warped.
Third thing effected by ZPE is life itself, what we have in our body's is a network of electrical nerve systems that transmit signals through our body's, so ZPE having increased over time the slower our signals move, on small creatures such as ourselves it makes little difference but on larger scale creatures it can be profound, if you take the largest dinosaur that existed it would take it about 40 seconds in todays ZPE to get a signal from its tail to its head and another 40 seconds to react, meaning that creature could not function on the planet today with current ZPE levels, we know their have been thousands of large dinosaurs and giant insects in the earths past from the fossil record, this just may be one reason in many why they no longer exist.
Sorry for the long post but I figured I needed to explain it so people understood what I'm talking about
