Einstein’s Theory of General Relativity predicts that accelerated masses emit gravitational waves, or ripples in space-time. Even though gravitational waves have yet to be detected directly, we expect that there are more than hundred million gravitational wave sources in our own galaxy. However, as of today, we know of only a few such sources.

A team of researchers, led by Dr. Mukremin Kilic of the University of Oklahoma and Dr. Warren Brown of the Smithsonian Astrophysical Observatory, have recently identified one of the best (and perhaps the most powerful) gravitational wave sources currently known using the Gemini Multi-Object Spectrograph (GMOS) on the Gemini North telescope and the Blue Channel spectrograph on the 6.5-meter MMT Telescope. Known as WD 0931+444, the object was first identified in 1982, and classified as a white dwarf with a low-mass M-dwarf stellar companion.

This new data from Gemini and MMT reveal that the white dwarf in this system is not in a binary with the M dwarf. Instead, it is orbiting another invisible white dwarf every 20 minutes. Thanks to the large collecting area of the Gemini and MMT telescopes, the team was able to obtain high quality optical spectroscopy of this system every 2 minutes and resolve the 20 minute orbital period.

The orbital separation of the two stars is only 20 percent of the size of the Sun. These two stars will lose angular momentum through gravitational wave radiation and merge in less than nine Million years. Depending on the inclination angle (which is currently unknown) the pair may merge even faster, in only a few million years. This previously unknown source is believed to be stretching everything around us (due to gravity waves) by a factor of 10-22 (or more) every 10 minutes!

The discovery of the true nature of WD 0931+444 indicates that there are likely many other strong gravitational wave sources hiding in plain sight. Some of these hidden sources can be identified through further optical follow-up observations as in this work. However, the direct detection of gravitational waves from these sources has to wait for a space-based gravitational wave mission like the evolved Laser Interferometer Space Antenna, which will likely not be operational until 2034 as currently envisioned.”

The strength and credibility of the logical evidence of the hypothesis concluded by the Yemeni researcher in astronomy Adnan Al Shawafi concerning balance of orbs
Has been further enhanced with a remarkable development in the position of scientists at Harvard-Smithsonian Center for Astrophysics, who declared that they have been mistaken in their findings announced in the second half of last March to have made the biggest astronomical event i.e. existence of exceptional energy pushing the matter at the speed of light and, thus, causing the universe to expand. Now, they belief that such statement enhances doubts over whether parallel universes exist along with ours. They contented themselves with the interpretation of what the telescope has provided regarding the extraordinary energy which they described as gravitational waves predicted by Einstein "Relativity Theory" about the beginning of the universe, according to the theory of the "Big Bang".
The Yemeni researcher is one of the first researchers in the world to object to this conclusion and in the same month it was announced by scientists at Harvard-Smithsonian Center for Astrophysics. He then described those conclusions as hasty and lacking evidence.
Objection by the researcher Mr. Al Shawafi is documented and supported by a clear scientific hypothesis about poise celestial bodies as part of his scientific study published in his book entitled: "Compound Balance Balls...an Approach in Astronomy" which took him more than 15 years of painstaking research. The hypothesis was posted on the Internet, after being documented at the official authorities of Yemen.
Meanwhile, the researcher has published a summary of his study and his objections to the findings by scientists at Harvard Center in several websites and newspapers on the Internet and both in English and Arabic. Moreover, he made several posts on the subject through many specialized forums, newspapers and international websites commenting on the conclusions announced by Harvard Center.
The attitude of Mr. Al Shawafi is not unique to him but reinforced with other similar stances expressed by scientists in many international universities, such as Paul Steinhardt, director of Princeton University’s Center for Theoretical Science, Philipp Mertsch of the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University, which widens the scope of controversy among Scientists on these findings early this month, prompting scientists at the Harvard Center to admit – in the 20th of June 2014, that their conclusions could not be correct.
In this context, the Yemeni researcher called upon universities and specialized research centers around the world to stand on his hypothesis, which was based on eight laws and eight mathematical equations explaining balance of poise celestial bodies in multiple universes systems and compound movements by these systems within the universe extra dimensions.
Al Shawafi's hypothesis interpreted the force unveiled by Harvard's Center as a result of repulsion forces at the nucleus of the galaxy, where the intensity of this force is more concentrated at both poles of the nucleus of the galaxy. The researcher says what is proved by mathematical equations, which compares between the size of the galaxy nucleus and the sharp decline in the movement at the two poles of the galaxy compared to the level of equatorial movement by the galactic nucleus, he concluded there is a strong repulsion force at the two poles of the galaxy pushing the cosmic dust, not gravitational waves, and that was not at the early universe as Harvard's Center suggested.
The researcher has also revealed a new dimension further enhancing the predictions and explanations of hypothesis concerning the event which was reported by the radio telescope. This new dimension indicates there is an exceptional attraction force at the equatorial horizontal level of the nucleus of the galaxy that polarizes objects toward the nucleus, which explains why stars are found at this horizontal level and distributed in the form of sandwich.
Al Shawafi added that his hypothesis asserts that the horizontal equatorial level of the galaxy has a very strong force that polarizes very stars quickly to the center of the galaxy and this is what gives the galaxy the shape of a dish at the galaxy level and makes planets in the solar system line up in horizontal levels close to the orbital motion of the sun. At the level of the universe, the hypothesis explains how cosmic systems are installed, symmetry of the universe directions, how can gravity link between the extra dimensions of the universe and the gradual increasing speed in the movement of galaxies. Besides, the hypothesis attributed that to the growth, size and expansion of the universe. It also showed the impact of black holes on the interior rarefaction within the universe structure.
The researcher concluded saying: my hypothesis may look different from previous theories, as it attributes gravity to motion and with that it establishes a new understanding and recognition of the dark matter secrets. The researcher suggests that what distinguishes the biggest theories that brought about a significant change in astronomy, is that they basically seen as different in its contents and the innovation behind them to address the problems that are currently debated in the area of Astrophysics.
Some news agencies, newspapers and international websites have recently reported that scientists at Harvard's Center have back stepped from their earlier findings meaning the topic is not resolved yet with a possible breakthrough in the coming months by working with Telescope Planck at the European Space Agency, and then to publish the findings.
To this end, the Yemeni researcher in astronomy Adnan Al Shawafi stressed the importance to take his explanations seriously, given his solutions and logical explanations enhanced by substantiated evidence about this cosmic phenomenon.
