In September, a theoretical physicist from Caltech, Lawrence Krauss posted an entry in his twitter account: “rumors about the discovery of the LIGO detector for gravitational waves. If this proves true, I will inform you about the details later.”
The participants in the LIGO experiment neither confirmed nor denied this statement, and many astrophysicists have called the Krauss “to be a real scientist” and not to spread rumors. However yesterday Krauss is back with a new tweet:
“Rumors, about which I wrote earlier, were confirmed by independent sources. Stay connected! Apparently gravitational waves were really opened! Cool!”.
There are many reasons to treat this with some skepticism — we don’t know the truth until then, while the participants of the experiment LIGO’t tell us about it. If the words of Krauss proves true, this could be a very important discovery.
As part of his General theory of relativity, albert Einstein suggested that very large objects can create ripples in the fabric of space and time — as walking on the sea ship. These gravitational waves may carry information about black holes, and also to tell us about the conditions during the birth of the Universe.
Although there is indirect evidence for the existence of gravitational waves, scientists still are unable to detect them and measure. And it is in this direction operates the LIGO experiment. Observatory laser interference gravitational waves LIGO uses lasers to detect gravitational distortion of space-time.
Krauss to believe or not is a personal decision. However, the present proof of opening can be seen only in officially published scientific work, and such we have not yet seen.
