Remember my lessons in EINSTEIN'S Relativity of TIME,SPACE co ordinates in a universal reference frame...back then at OAU ile ife


If you don't understand the importance of this discovery , think of it this way

There are different waves like

SoUND WAVES
LIGHT WAVES,under ELECTROMAGNECTIC WAVES

WATER WAVES
TIDAL WAVES
VIBRATIONAL WAVES ETC
Now

GRAVITATIONAL WAVES


Just like electromagnectic waves propagation makes it possible for us to send and receive radio signals,radar signals,television signals and even make and receive calls.

Gravitational waves propagation ill make it possible for objects to suspend in the vacumn or air without hitting the earth grin
It has the potential to transmit and receive matter.
Just like e can transmit and receive sound and light signals..grin

The potentials are inumerable tho


Physics is wonderful


Nice one.



Big up einstein
The greatest scientist ever

Gravity waves do not move celestial bodies around. They are the result of movement of celestial bodies. Finding a "reference" to them in Quran is a classic case of confirmation bias, where the flimsiest scrap is used to "confirm" what you already believe. Only a very specific scientific description would hold water as evidence that the Quran foretold of a scientific discovery. This sort of idiocy gets posted all over the internet, about all sorts of scientific facts and discoveries, and just makes believers look ignorant, gullible and silly. https://en.wikipedia.org/wiki/Confirmation_bias

1. Sorry it is an error of representation I meant timespece (x,y,z,t)

2. You never can tell......Even nuclear energy is still destructive yet we harness it today with the appropriate systems.

Nuclear energy is destructive only in terms of runaway radiation and uncontrolled chain reactions.

Supermassive blackholes are destructive by reason of being. The gravity waves decline to infinitesimal levels when they propagate out beyond into space.

Perhaps studying gravity waves may make us better understand Dark Energy, which if harnessed can lead to the sort of practical applications you theorized eg anti gravity, zero point energy, time contraction etc.

Always knew it was a matter of time. Not surprised at all. Einstein's prediction was quite inevitable for me. Even his works on the theory of "everything" in his later life haven't been looked at fully.

I recall writing an article in the science section of my high school's magazine about The possibility of making flying cars both functioning against gravity or using anti-gravity principle based on the then "Fictional" or "indiscernable" Gravi-waves and more.

Science is always awesome and insightful only when people learn to look @ things "wholly" and from "all possible angles".

Restriction/limitation of knowledge or views due to extreme religious thinking or extreme atheistic thinking only blinds people to the whole big picture of science.

Einstein understood this.

That's actually not a new thing. Newton (oops!) has to his credit even much more stunning predictions. But of course, it's hard to get over that Einstein pop culture.

You have no idea what you just wrote up there. Honestly trust me. I am still in awe as to how smart Einstein was. According to Neil deGrasse Tyson, he said in Einstein's equations of relativity, there was a term in his mathematical equation that he called a blunder, simply because he thought the term was physically meaningless (the term predicted that the universe will be expanding or collapsing). Few years later Edwin Hubble (he invented the hubble telescope) discovered that the universe is actually expanding. According to deGrasse Tyson, "Einstein's blunder is saying that he made a blunder". Einstein's intuition is unparalleled.

WHAT IS IT PLS

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.

This is beautiful, now the question is who found or discovered it first, visit the link to find out
http://facttellers.com/who-spotted-those-gravitational-waves-first/
mcpat:
Scientists at Washington’s National Science Foundation and Moscow State University have confirmed the discovery of Albert Einstein’s gravitational waves. The breakthrough, possibly the biggest in physics in a century, could be the key to new understanding of the universe.

Recent rumors of the success in detecting gravitational waves, or as some scientists put it "very weak spacetime wiggles which propagate at the speed of light" were officially confirmed Thursday.

"Ladies and gentlemen! We have detected gravitational waves, we did it!," LIGO laboratory executive director David Reitze announced in Washington.

"These gravitational waves were produced by two colliding black holes, [that] came together, merged and formed a single black hole about 1.3 billion years ago," Reitze said.

These ripples in the fabric of spacetime are one of the most important variables in Einstein's theory of relativity and it took astronomers decades to detect them, although they were pretty sure that gravitational waves existed.

The discovery has been made with the use of the Laser Interferometer Gravitational-wave Observatory (LIGO) - a system of two detectors constructed to spot tiny vibrations from passing gravitational waves. Funded by the National Science Foundation, LIGO's identical detectors are located in Livingston, Louisiana, and Hanford, Washington.

The observatories, which are "the most precise measuring device ever built," recorded a signal on September 14, 2015, "nearly simultaneously," and the signal "had a very specific characteristic," the laboratories' director said.

"As time went forward, the frequency went up," he explained, adding that it took scientists months of careful checking and analysis to confirm that what had been discovered was exactly gravitational waves.

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 Also like how they think gravitational waves have just been verified when this is actually the second time. the first time, earned the physicists involved Nobel prizes.

I Also like how Nigerians are surprised that Einstein could have made a Hundred year prediction that turned out right. when scientists have been doing this since the inception of time.

from Kepler predicting solar eclipse for future decades, Poincaré's conjecture, to Fermat's last theorem. which actually spanned 350+ years, The prediction of thousands of atomic particles not excluding the Higgs boson that was recently discovered, antimatter, Entire Atomic table! down to the color and shapes. so on, Riemann's hypothesis which has been verified for the first 40 million numbers, the predictions of Ray Kurzweil, Isaac Asimov, michio Kaku, which have all turned out right.

Your pastors make yearly, Vague "prophesies" and you lot swoon over it, and most of the time, they don't come to pass! Yet, scientists make incredibly specific, concrete predictions spanning several decades to centuries, and you are all like . . . Scientist are still inferior to my pastor. angry
