Pretty much every post you make in the Physical Sciences forum shows us why science cannot use God as a hypothesis.

It cannot, because it has ruled out all but this natural world. It has painted itself into a corner, from which there is no escape.

Obviously light moves at the speed of light. .

Have you any evidence light moves at the speed of light in the far universe?

Assuming no time dilation corrections for faster decay rates?

Using your own argument have you adjusted your own biological age for time dilation since you are in the same accelerated frame?
The human body can be used as a biological clock as Galileo demonstrated using his pulse rate to time the period of a swinging pendulum.

So tell us your true age, thousands of years old, tens of thousands of years old...........

Welllllll…. it has to by definition.

OT: The speed of light. I have heard from many sources, that a solid can never reach the speed of light. I have to assume they mean there, the speed of light relative to some point in spacetime.

What it means is that you can't accelerate from less than the speed of light to the speed of light. What happens is that at velocities significantly close to the speed of light, distances shorten in your direction of travel and your time slows relative to the rest of the universe. This means that, from your perspective, you can keep accelerating as much as you want and your journey time (as you measure it) will reduce - although not as much as you'd expect, because your mass increases, making it harder to accelerate. External observers see you getting closer and closer to the speed of light but never reaching it.

The time dilation and length contraction can be calculated using the 'Lorentz Factor'. This is very close to zero at low speeds, but as you approach the speed of light, it rapidly shoots up to infinity. At 95% the speed of light it is 3.2, so your time slows by a factor of 3.2 and lengths are contracted by a factor of 3.2 in the direction of travel.

A nice example of the time dilation & foreshortening effect is the fact that we can detect muons (created by cosmic ray collisions high in the atmosphere) at the Earth's surface, although the muon's lifetime should be too short for them to reach the surface. But their speed is enough that we see their time running slower relative to ours, giving them enough time to reach the surface, and they see the distance to the surface as shorter so they can reach it within their lifetime.

I have also heard that when an object reaches the speed of light, it becomes energy.

An object can't reach the speed of light, and energy isn't a thing in its own right, it's a property that stuff has by virtue of its context or construction; so what you heard doesn't sound right.

If that is true, when object #1 is approaching the speed of light, compared to location A, and object #2 is traveling an opposite direction, say at nearly the speed of light, then they each to the other would seem to be energy. I wonder then, is all matter actually energy, since it is obviously receding from some point past the speed of light? You seem to imply that no perception of one to the other would be possible, so the question is moot. Yet it seems to me that perception is not the definition of reality. (I.e. the fact we don't see that object receding from us does not mean it is not). We see all objects as cohesive reality; in the less abstract mind, for that object to become energy, how can if remain cohesive, so that as it slows it becomes the same object again?

I have no idea what you're asking here.

I ask all that to introduce the following question: Is all energy matter sped up, or the potential to be matter if slowed down? If so, would the waveform of that energy define the matter it becomes? and vice-versa?

No.

I understand all this seems to assume that the whole object reaches the speed of light at the same time, which is not proven, nor does it reference any relation of the action of the atoms and their parts within the object to the speed of the object.

It can't reach the speed of light.

If a "universe", then, is separating from this one faster than the speed of light, there must exist spacetime between the two, by which the difference can be actual, no? If the direction from the one could be known, could not a theoretical spaceship, traveling from the edge of this "universe" approaching the speed of light send information at the speed of light relative to that ship toward the departing "universe" faster than that departure? (I put "universe" in quotes, since these seem more like galaxies to me than universes, since I have heard that a universe is defined by spacetime --there being no reality (spacetime) outside of it).

The speed of light is not additive. Every observer always measures it to be the same, so if you're travelling near the speed of light towards some observer, and you shine a laser at her, she will measure the laser as approaching at the speed of light, but she will see it shifted in frequency way up the spectrum. If you were going away from her and shone a laser at her, she'd still see it approaching at the speed of light, but shifted way down in frequency.

Uh huh.

Only as defined and observed and measured here in the earth and solar system and area. What has that to do with the distant universe?

 

[dad]

Uh huh.

That's right, science is a study of the natural world. The physical world.

1. the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment.

It can't reach the speed of light..

Physical only matter is not any indication of what speeds spiritual/physical bodies can travel. Gabriel came from where God is, and His throne, beyond where stars are...to Daniel's room instantly. Gabriel was there before Daniel finished praying and opened his eyes. The speed of light as observed in the earth and area has nothing to do with time and space in the far universe and beyond, or even here when there is more than the physical involved.

Do you basically claim that radioactive decay rates on earth in the days of Adam and Noah were affected by time dilation? If so, then would that have no effect on other aspects of the world and nature at the time?

You are outlining a non-Christian point of view. The entire physical universe is created -- including the most distant galaxies an stars.

God is not created and God does not reside at some specific location in the physical universe.

Nonsense. No one says heaven is physical only. No one says angels or spirits are either. No one says the future is physical only. No one says the past was either. As for your conception that
distant = older than earth...that is not Scriptural. Name any place in Scripture that says all of creation is and always will be physical only???! How dare you accuse me of having a non Christian point of view!

Angels are created also, are they just physical? Name anywhere in Scripture that says deep space is purely physical?? In fact stars are associated with the spiritual time and again! Please find a good mirror, and take a good look. Your claim of having a non Christian position...it will not on my end.

More importantly who cares what science thinks unless they know? That is called belief.
Now you descend into prophesy. The bible has prophesy also, and I assure you, science will not be making rockets in the kingdom of God coming to earth. You hinge all your bets on the present being the key to the future. That is blind faith and faith alone.

You can resort to any belief you like but what you may not do is pretend that a same state past and future is not belief.

You should understand, that once the battle is limited to the field of beliefs only, the fables of science fall into some distant double digit number insignificant place in the race. Back of the line they go. That is the name of the game. Your quest was to try to show that the models of the future and past by so called science were not just beliefs, but proven and known and evidenced facts.

In other words you offer us a few hundred fishbowl years and how things work here and now. I offer you the back of the line in the religious line up. Better still, I offer you the word of God which is the front of the line.
The laws of this state or nature do exist and work and are real. Have you some reason you expect they would not work now? The issue is not the present. The isse is you trying to impose present nature into the far future and past.
Atoms do exist as well as all the forces and laws of nature. Now your quest is to show us they always will and always did.

I'm reading this and I feel like I'm being asked to "prove" that the world and everything in it wasn't created Last Thursday.

Science? It means pretty much what I’ve spent my life doing. And it means knowing your argument for what it is. (The last bit also requires logic)
