Just like a second dimentional living thing can't imagin a world in 3rd dimention because it's simply not part of it's world. If we think of the univers maby that's the 3rd dimention the one we live in and the fourth one is what we are moving into. How can we fathom the thought of what we make up? It's like standing on the ground and trying the make out a crop circle when someone from a plane can easily make it out. The univers is are world and all we can see but something holding the univers I mean it can't be just floating out of no where but we can't see it because it's so much for us from where we stand to understand it.

The three dimensions of space and one of time make up the four dimensions of space-time continuam proposed by Einstein. Modern string theory (not yet accepted by all) speak of 11 dimensions.

Taking the four dimensional universe, I have this viewf of a fifth dimension, like yours - not very scientific but possible. When a person dies he/she passes into the fifth dimension. From there one can see the world. I call it the spiritual dimension., but now it is no more science but religion.

For our knowledge to be comlete we must accept both - science and religion - as complementory, not contradictory.

Ya that makes sence because we can't see what we are apart of almost like a cell in a body dosent know what it's overall purpose is to make up a person, it just knows what it's doing so in a sense the universe is our cell and we just can't fathom what the universe is all about right now just speculate.

I'm just running on a thought but if matter can't be distroyed maby same with energy. Dosent matter what you do it will just be transfered or changed into another form of energy sound heat ect. or even something els we can't sense. When an atom is split it gives off so much energy it probaby took that same amout of energy to put that atom together at one time. Now no ones ever told me what protons and nutrons do but if theres that energy in that stable structure those protons and nutrons could be doing some function in a way kinda like a plant or animal cell and as a reaction to this it gives you gravity. If you can help me to understand this if I'm completly off that would be great thanks

I don't think I got what was in your mind when you posted this. Let me just make the following comments from what I could get of your question.

We know this much. Mater and energy can be converted from one form to another. Energy can be converted to martter and matter to energy.
What causes mass of matter and gravity is still under dispute. What we learned from Newton and Einstein regarding gravity do not explain the present rate at which the cosmos is expanding. Nor can we say that your line of thought may or may not lead to a new concept, one step nearer to the Truth. Physics alone can never reach the ultimate truth. Only a combined aproach by physics and metaphysics - by science and mysticism - can bring us to truth.

Millions of years ago we had that one mass of land that split apart to form the contenents that we all know about now because of the tectonic plates. Human life was on most of thouse continents and eventually we evolved to what we are now with different variations between races due to different enviroments food, weather etc. Now what happens when we don't have any ristriction to what we eat and where we go I don't have any thought about it but I'd like to hear from someone about where we might be heading?

I guess you mean the differences in skin colour and suchracial characteristics. At present the major factor is genetics. We inherit these qualities from our parents. The effect of climatic conditions take very long periods. But they have gradual effects that can be seen after many many generations.

This question has been trubling me for along time. Do we have any facts supporting the idea that light is a wave or a ray because I really have a hard time understanding how light can hit every spot on an object and fill in the gaps of every spot that isnt in the direct line of the source of light. If a star millions of light years away that are giving of light rays those rays over that distance would almost practicly miss earth. Wouldnt it me more beleavable to call it a type of emershion of energy almost like water that just filling in all the gaps?

Light and other electromagnetic radiations like heat, U V rays, etc. propogate in the form of waves. We have simple means of measuring accurately the wavelength of different colours of light. As it travels as waves it can flow like liquid as you imagined.

OOO ok so theirs so many it just basicly can cover every spot and still reflect into every direction so no matter where you stand you will always be able to see it

Can energy be destroyed? Because if not it can only be transferd from one thing to something else or it can create something. Could it be fair to predict that the same amout of energy that is giving off when you split an atom could be similar to the amount that was probably needed to put it together at one time?

Question found in Science In General
Matter is converted into energy by nuclear fission or nuclear fusion. Even so enrgy can be converted into matter. It is a generally accepted fact that at the begining of time matter was created from an immense ocean of energy which the scientists call vacuum state.

When a star is dying it burns up the last of the last of the matter that's sustaining it so it colapses into itself exploding into whatever you want to call it depending on the size of the star right? And I'm guessing since a black hole has a greater gravitational pull then a star it has more matter in it just we can't see it because everything that goes into it dosent come out even light right? So my question for you is if everyones going with the big bang theory what caused the bang because as far as I know since the most matter in one place that we know of becomes a black hole then wouldnt the big bang theory be one huge Black hole? Just a guess but if you had that super massive black hole and it really sucked in everything into it matter and space and it had nothing else to pull in that gravitational force could somehow reverse itself. Sorry for the question I'm 16 and really have alot on my mind if you could clear things up for me that would be great thanks.

Question found in Science In General
Big bang and black hole
A question of this nature from someone your age is really to be admired. If gravity was the only force at work there would have been no universe. Einstein suggested another force antigravity that allowed for the expansion of the universe. Recently the concept of antigravity is replaced by dark energy.

Today cosmologists do not speak of Big Bang. The primordial matter that appeared at the beginning of time did not explode or scatter but started a very fast process of expansion called inflation. According to all known facts or theories in gravity or in physics, the rate of expansion of the universe must be slowing down and must be on the way to a big crunch leading , may be to a big black hole. The whole scientific community was surprised by the end of the 20th century by the discovery that the rate of expansion is increasing instead of decreasing. This was soon confirmed by another group of scientists.
But the question, what is dark energy? has not yet been answered. It is not ordinary form of energy it cannot be detected or measured. It is something immense or infinite that controls the evolution of the universe. It could very well be the immense ocean of energy which gave rise to the primordial matter at the beginning. This infinite force that created the universe and controls its evolution and existence may never be fully understood by science. But it can very simply be understood by us as the Creator or God. A cosmologist may very well be aware of this but he cannot use the word God then it is no more science but religion. Besides we have to go on trying to find answers to question like; what is all this? to expand our realms of knowledge.

Thanks for the help! It almost upsetes me that we won't be able to know everything but we can't do much from our position as we observe the universe from such a insignificant spot in the universe because truthfully how can we even fathom the concept of something we can't see or touch.

If space is a vaccum it's not going to have any resistence to stoping all the matter from the big bang but what if some how they where linked to each other by gravity that will in the future it will pull itself back into itself crunching itself into a masive black hole doing crazy stuff!

Your question is one that had baffled cosmologysts for quite some time. From time of Dr. Einstein many things could not be explained. One was this question of gravity. Why are the galaxies flying away from each other?
First came the big bang concept. That they are scattered from a big explosion. But then after a certain distance the gravity should pull them back into a big crunch. Though it is not yet time for that inward movement scientists believed that now the speed of expansion must be decreasing. But science had more surprises. By the end of the 20th century there was the surprising finding that the universe is accelerating - that the rate of expansion is increasing instead of decreasing.

Scientists, cosmologists today realize that there are so many questions whose answers are eluding us.

Since atoms when split give you an intence rapid release of radiation could it be safe to predict that at one point emence amounts of radiations in the universe came together to create all matter?

Discuss this question

Question found in Science In General
Before the creation of matter there was no universe, no radiation. But it is possible that there was this inexplicable kind of energy, something like the dark energy suggested by modern cosmologists to explain the present state of the universe. We cannot detect or measure this; it is beyond sciene. Some think of an infinite ocean of energy that is eternal or not limited by time, as the source of the original matter.
Some call this the impersonal God, the creator. But sciencs cannot use the term as then it is no more science but becomes religion.

An atom contains protons and nutrons with electrons orbiting the structure of it like a sun with planets stuck in it's gravitational pull right?can we expect that thouse nutrons and protons could be a build up of something even smaller that some how create a function similar to that of a living human or plant cell?

Discuss this question

Question found in Science In General
Now we know that protons and neutrons are made up up still smaller particles caled quarks and gluons. Three quarks for each hadron (P or N). Gluons hold these together.
We do not know yet if we can go to the level your facncy took you to. If you go that way, we might then imagine the whole universe to be one of the many particles making up a larger multi-verse. There is talk of multiverse but not much. All I can say is that the horizons of knowledge is ever widening.

Comments :
Cool because the energy that was used to put that atom together at one point might be geting used up slowly that's giving it that gravitational pull energy that we don't fully understand yet.

Is it true that chemical reactions are begun by the behavior of electrons?

Discuss this question

Question found in Science In General
You could say that.
The chemical activity of an element depends on the number of electrons in the outermost orbit of its atom. Tendency is to keep the outermost orbit full.
Sodium Na has its 11 electrons in three orbits 2, 8, 1
chlorine Cl has its 17 distributed as 2, 8, 7.
These two have great afinity for each other and make pairs or weds by sharing - give and take. Na gives 1 and Cl takes it so they have orbits as
Na - 2,8 and Cl - 2, 8, 8. Both are satisfied. This is how common salt - NaCl is formed. Losing one electron Na acquires a positive charge while gaining an electron Cl gets a negative charge. These are now ions. Many reactions among molecules are also controlled by electrons as they are mostly ion exchange reactions.
