its all about gravity.

There are two ways in which gravity is seen and understood. The classical Newtonian sense, and the modern Einsteinian sense.

I will start with the classical and Newtonian sense: according to Isaac Newton, gravity is that invicible force that reaches out and instantaniously grabs hold of objects and keep them in a fixed position in space. For example: the reason the solar system has the shape that it has, i.e the sun being at the center, and the planets revolving around it in orbits that are more like concentric circles, is due to the force of gravity. According to Newton, this gravitational force can be measured by the equation F = GM1M2 / r^2.

This Newton's idea of gravity stems out of his philosophical idea of space and time. According to him, space is absolute! It is not dependent on external influences. To him, Time is also absolute; it doesn't matter what the other factors are; time will always be time! I personally think that our saying that "time waits for no man", actually stems from the newtonian philosophical idea of time; that it is absolute and respects no other physical quantity.

If we were to create a cosmic catastrophe like blowing up the sun from existence, what will happen to the planets revolving aroud it like Newton understands and predicted, would be that the planets will INSTANTLY kareen off into space in a direction that is tangential to the circular orbits in which they move.

Newton sees gravity as a FORCE!

Einstein disagrees with Newton. For him, gravity is not that INSTANTANOUS force that reaches out and grabs hold of objects and keep them in positions in space. According to him, yes gravity reaches out from one object in space to another and holds it in mean position, but its just not instatanous! Einstein believes that gravity is caused by the warping and curving of the fabric of space and time; and that if we were to create that same cosmic catastrophe we created earlier, the planets will not instantanously start moving away from its orbit as soon as the sun disappears, rather it will take atleast 8mins for our planet to stop feeling the effect of the gravitational force between it and the sun which has just been blown up and doesn't exist anymore.

To make you understand better, let me explain to you what Einstein meant by "...the warping and curving of the fabric of space and time" and how he feels it's what creates the gravity that holds matter in space.

First of all, space in this sense, means an area, wether or not it is occupied by something. For example, the area around you; the "space" around you.

Now this space is three dimensional; it is three dimensional because it has three sides to it. Every object in our universe and in this world, including you, is three dimensional. You have your height, which is the vertical distance from the soles of your feet to the top of your head; you also have 'wideness' a horizontal distance from one of your shoulders across your chest to the other shoulder. Then, you have your 'thickness' which is another horizontal distance between your front, throught your side to your back. This means that you, Oluface, are a three dimensional object. Every single object you find in this world has these three dimensions too. This is why we say that space is three dimensional.

For time, time is the duration through which an event takes place. Events have starting and end point. The duration between the start of that event to the end of it, is what we call the elapsed time of the event. The only reason we can notice happenings is because of time difference. Unlike space which is three dimensional, time is one dimensional; it can either go forward or backward. And speaking from what physics can tell us, in the real physical sense, time always move in the positive direction.

Einstein likes to think of space and time as not two separate entities; he believes that space and time are condensed and bound together in a sinlge fabric he called SPACE-TIME. This means that space-time is no longer the 'pumped' thing anymore, but more like a thin clothe, hence the word "fabric".

Back to explaining the "warping and curving..." i mentioned earlier, think of your friends holding out a bedsheet by the four corners. Think that the bedsheet is space-time. Then you drop a football (sun) at the centre such that the ball digs into the bedsheet and causes a "curving" outwards. Picture a smaller ball, say a table tennis egg (earth), on the wall of the "curving" caused by the football's (sun) presence. According to Einstein, this "curving" is what causes gravity to hold both balls (sun and earth) in their positions.

In 1915, Einstein predicted that this gravity ripples out in form of waves to grab hold of objects in space. So all the things you are hearing today, is actually a real physical confirmation of his proposed theory.

Today, gravity is not a force but a wave.

I enjoyed. ur write up, but the last line ' gravity is not a force but a wave' are u saying there is no longer the force called gravity? Cos I knw we have electromagnetic waves and electromagnetic force.

how long can you live on Earth to witness changes that take thousands or millions of years to happen? OK I dey come

Directly, it doesn't. It just lends more credence to science and the scientific process.
Consequent disbelief in all the "myths" out there is just an inevitable by-product.

so, does it have any effect if I continue running?

yup, you can trigger arrhythmias or you can activate conditions that are lying dormant, so its best to do this exercise in a cardiac stress testing controlled environment. wear a holter monitor for a few days to see what your rhythm looks like over a long period of time. do a stress test to see the ST elevation during exertion to see if you have any clogged arteries. if everything checks out clear, then its only because you are not used to that level of exercise so i will advise to start slowly and increase your level of exercise every week till you get to the level you desire.

I think I also saw one part where you asserted that scientists are humble . . . you DO realize that the only thing that makes people scientists is them actually studying science, right? and that it has nothing to do with whether they are proud or not?
Knowing that, don't you feel extremely uneducated to make such inaccurate generalizations?

You humans are just de ones making things complicated for yourselves. Someone gave you simpler one, the way He did it. But some people said "noooo,it can't be truth, this is how we think it is"

Who doesn't know that scientist said, life started from molecule to cell to organ to system to what ever. Why isn't that process occurring again? Why only once? Then why are we not evolving to something else if we humans evolved from ape.

Mr man, you are just bitter that God "didn't pick your call" so you think there is no God. That doesn't change who He is. SEEK Him to know Him and not to know if He is there

Why does a ball fall down when thrown up?

here's a simple answer: God did it.

A more complicated answer requires two years of dedicated study of Newtonian and relativistic mechanics of gravity. and it's precisely because of the complicated answer that you can get your message across to me. that you can watch TV and monitor the weather.


A wise man once said, things should be made as simple as possible. but not simpler.
to your questions, there are answers. the problem is that you won't understand them. . .

you know what, fine. I'll answer them anyway.

life started from molecule to cell to organ to system to what ever. Why isn't that process occurring again?

Because the conditions required to achieve this are rare and somewhat difficult. At this point, using simple molecules, scientists have been able to synthesize complex peptides. and it took violent reactions for them to achieve this. and besides, you cannot say if the process is not occurring again. seriously. new life can be arising from non living molecules right now, and you simply wouldn't know. mainly because they don't advertise themselves. even already established lifeforms are constantly evolving over time and most of the time, this evolution is unnoticeable.

Life is the most complicated thing the universe has offered us. So obviously, It will be one of the latter things we completely figure out. never the less, It would be dangerous to simply assume an entity whose existence cannot be proven, is the cause.

Teempakguy:

Yes God did it. He created heaven and earth including the gravity and even to the micro elements that made up the ball

Thunder doesn't strike a spot twice...that's a lie. It might no be twice in one's lifetime. But in a thousand year, it will strike twice. I wonder why such "rare conditions" can't occur again since it is random thing no one was controlling then like a chef mixing dough ingredients.

So that means two different dough were mixing, one male the other female? Why didn't both dough have a male organ?

I knew this would happen.

how can life come out of living molecules. retarded question. no doubt.
when Have you ever had to eat a fish that was totally alive? trust me, the food that you eat is completely and totally nonliving. and yet, your body manages to synthesize trillions of cells which are living, from these nonliving materials.

The question you should be asking is, How can nonliving things become living things without the help of other living things?

and I can't answer that question. because science Just isn't there yet. And that is the simple truth. one thing though, when science does get there, what are you going to do?

that's what Einstein seems to have predicted and has been confirmed now. Until now, and until Einstien, we've always thought of gravity as just a force, a push or pull, and nothing else. But now, scientists are telling us that it is a wave, essentially.

This is unbelievable to me, i cannot understand it! I do not believe this modern physics led by Einstein. Newton is a bit more inspiring to me.

If you say Gravity is a wave, then i will ask: does it also posses all the qualities of a wave namely: interference, reflection, refraction, diffraction, polarization etc? What kind of wave is it? A mechanical or an E-M wave or just an entirely new type of wave with its unique characteristics? These are some of the questions i am curious about.

PLEASE DO NOT TAKE MY WORDS FOR THEM; MAKE SURE YOU VERIFY THEM BEFORE YOU CAN TAKE THEM AS FACTUAL. THERE ARE ALOT OF THINGS I MAY BE MISTAKEN ABOUT.

CSTR2:
Those in the know will agree that isaac newton was the greatest ever. Unlike einstein, he was a practical scientist with far relevant inventions and discoveries that formed the building block of modern science.
And he lived hundreds of years before einstein and didn't have the opportunity of relatively sophisticated scientific equpments, and materials that einstein enjoyed in his time.
Eistein as good as he was , is still some rungs below newton.

i prefer classical mechanics to the General Theory of Relativity and Quantum Mechanics. The reason is that: studying classical mechanics provides you with a bit of fulfilment unlike quantum mechanics and general theory of relativity whose interpretation, we cannot know to complete and absolute precision. Studying them, leaves you hanging somewhere!

Comparing the two scientist's privilages, isn't something very fair. I think their aparatus is relatively sophisticated for their works and discoveries.

Lol. But isn't that the fantastic thing abt science? The fact that we do not know, are willing to admit it and kp searching? Gives life some sense of purpose!
Newtonian classical mechanics mostly applies to the realm of human experience and reality (medium-sized objects moving at medium speeds)..it's done and dusted! We have moved beyond our realm to Special Relativity (extremely high speeds), General Relativity (extremely large masses) and Quantum Mechanics (extremely tiny sub-atomic scales). The Hallmark will be the unification of all these in the still elusive "Theory of Everything" a.k.a. String Theory. These are exciting times for Physicists! I'm not evn one...I'm just a huge fan.
Back to the topic at hand...some ppl were discussing the practical applications of g-waves. Lol..guys chill! It's way too early! Imagine what had to come together for the g-waves to be detected in the first place.
First, based on the observed signals, LIGO scientists estimate that the two black holes that collided for this event were about 29 and 36 times the mass of the sun, and the event took place 1.3 billion years ago. About 3 times the mass of the sun was converted into gravitational waves in a fraction of a second—with a peak power output about 50 times that of the whole visible universe!
Second, the LIGO detector itself. It was a real tour-de-force of Science & Engineering. The detector had L-shaped arms with each arm a whooping 4km long, and there were two locations of this same set-up in different states, and with a capability of detecting a change in the lengths of the arms smaller than one-ten-thousandth the diameter of a proton (10^-19 meter)! If that doesn't make your head spin, nothing will.
This was just for detection. Imagine what has to be built for practical manipulation. Nah...not in this generation nor the next!
