It's interesting. I've always done really well in science. I pulled A's in it all through school and college. I however don't believe macroevolutionary theory. I've also come to disbelieve in the constancy of speed of light thorughout history even within a vacuum. This flies in the face of accepted theory. The constancy of the speed of light is the basis for several scientific theories. One thing at a time... Thermodynamics tends to fly in the face of so many other theories. Now, I'm not prone to believe that relativity absolutely breaks down with a nonconstancy of speed of light. Galileo fathers the relativity concepts. I would say that the known universe (all matter and energy discounting space outside these boundaries) parts is affected by all other matter and energy within the universe. I'll state it better. The placement of matter and energy throughout the cosmos does have a boundary though that boundary is constantly increasing into space. Despite that ever increase, we'll concentrate on those boundaries where matter and energy extend to.
It would seem that matter and energy are affected constantly by other matter and energy. There seems to be a field or fields of energy throughout the inward boundaries of the universe. As the matter and energy constantly moves outward past the said boundaries, it would seem that various laws are constanly affected by the expanse whether it be the various fields, the speed of expanse, and even the possiblity of the nonconstancy of speed of light due to this ever-advance and changing affects of fields throughout the ever expanding universe.
Now I admit that I take Genesis literally. I don't believe in the Gap Theory or other theories that are spliced together to reconcile Christianity/Judaism with "accepted" science. Some would call that a handycap, in that I believe the scriptures to a tee. I would call it a strength but it does kinda lend to the idea that beauty is in the eye of the beholder. Or that logic is in the mind of the observer. I dunno.
I again say that relativity isn't necessarily attacked by the possiblity of nonconstancy. I would say that laws remain constant relative to each other as the expanse ever increases. This would or could possiblity keep the speed of light basis for other laws and theories in tact. I would hazard to say that as the decrease of lightspeed affects all other theories but not in so much a noticeable way.
Another factor... As the expanse of space increases, matter and energy tends to draw all other bodies and at times repels all other bodies. What if a slingshot effect is occurring? The universe (energy and matter) are expanding uot constantly due to being "slung." But then as matter and energy are slung out, they're still being pulled upon if even ever so slightly noticeable. It would seem that there is a posibility that the universe will snap back in the time to come. I wonder if the lightspeed would even increase back to its former state as the matter and energy pull back to the core of our universe. This would seem to evevn affect gravitational forces through all of our universe (locations of matter and energy and all the in between).
Now we know, gravity can affect how we perceive time. Even speed can affect how time passes for all things within the thing moving... One change in the governing laws affects the laws abroad maing it unnoticeable. Hmmm.
As for thermodynamics, the layout I have here would seem to indicate that the universe is a closed system due to the factors I've stated. That said... The First Law of Thermodynamics states the following that the total amount of energy in our universe, or in any isolated part of it, remains constant. Furthermore, energy can be transformed from one form into another, but it cannot be created and cannot be destroyed. As a consequence, the current amount of energy in the universe has been in existence for a long time. Natural processes cannot create energy, thus this energy could have been produced only by a force outside our universe. According to evolutionists, complex organisms evolved from simpler ones. Simple organisms were formed from matter and energy. They state that matter and energy appeared from nothing. This contradicts the First Law. On the contrary, Creation is supernatural and stands above the laws of nature. God can create matter, energy, and laws that govern them.
According to the Second Law of Thermodynamics, the energy available for useful work decreases in an isolated system, although the total amount of energy remains constant. This is because energy can transform only into lower forms of energy through natural processes. For example, electric current passing through a light bulb ends up transforming into heat, which is the lowest "quality" energy consisting of chaotic molecular movement. This Second Law introduces the concept of entropy, a measure of disorder. Entropy constantly increases in any isolated system. In other words, the system becomes disorganized and energy becomes less usable. Based on this law, the amount of information conveyed by a system continually decreases and its quality deteriorates. Basically, the law states that natural processes disorganize the state of objects and systems. Over time, everything decays and becomes disorganized. The universe irreversibly heads toward maximum disorganization. Just think about what happens with our house if we "comfortably" leave it by itself for a while, we don't clean up, arrange and mend all the time. Natural processes constantly destroy and disorganize it. Our house needs our useful and expedient work to maintain the order. Even atomic particles search the lowest energy levels, they "like comfort". The amount of information and the complexity of our universe perpetually decreases instead of increasing. According to evolutionary theory, life on earth progresses from simple to complex and never vice versa. Everything becomes more and more organized and entropy constantly decreases. Thus, macroevolution contradicts both laws of thermodynamics.
According to the Second Law of Thermodynamics, everything degrades and breaks down. We can see this in the universe. The sun slowly but surely cools off, stars die, matter dissolves into radiation, etc. Our universe progresses toward its death, namely toward maximum entropy. This process is irreversible. If there was no Creator, this tragic end would certainly occur.
The Two Laws of Thermodynamics point not only to a death in the future, but also to the Creation in the past:
According to the First Law, the cosmos could not have created itself, thus an external force must have existed to create it.
According to the Second Law, if our universe was infinitely old, it would be dead and destroyed already. But this is not the case, so it must also have had a beginning. Sometime in the past the universe had been created and the cosmic processes were started.
Every star, the perfectly designed nature and all the accurate laws of nature bear testimony to the existence of a Creator who created them all.
We think that the amount of information is continually increasing on earth. Day after day, new inventions appear, just think about the development of the computer. How does this contradict the laws of thermodynamics? There is no contradiction, for these inventions were not the random result of natural processes, but human intelligence. Humans create the programs running on computers to make them do useful work. Natural processes don't produce anything with a goal in mind. Having a goal means thinking in advance.

The idea of the breakdown of all things within the universe doesn't fly in the face of the nonconstancy hypothesis. Even the slingshot effect as the the universe returns to the core doesn't contradict this idea because as it returned to the core, collapse and degradation are the ultimate result, even with the increase of speed of light and relative affect on other laws as the phenomena occurred.

Your thoughts if any?

she marked it wrong and put that it was suppose to be 10^positive 9 ????? but why????? isn't the scientific notation for n 10^-9?????

n nano

if you don't get wut im saying let me kno and i give you another problem where she did that....

The question is..

An electron involved in energy conversion in photosynthesis travels about 100 micro meters in 3.0 milliseconds. what is the average speed of the electron in m/s. (metres per second).

and then convert the answer to km/h.

I got 0.33m/s and 1.2km/h.

Is this right? can someone varify for me?

I used to formula v=d/t

v=speed
d=distance
t=time
