Astronomers have likely discovered the most massive collision of two black holes ever recorded. The chaotic connection of the two objects took place about 7 billion years ago, and now we have received the signal emitted at that time. Thanks to the LIGO and Virgo instruments, researchers were able to observe the birth of one of the most sought-after objects in the universe. Two actors took part in the performance: a black hole with a mass of 66 solar masses and a second black hole with a mass of about 85 solar masses. The two black holes approached each other, orbiting each other at the end at a rate of several times a second, until a collision occurred, during which powerful ripples of space-time were emitted, which spread out across the universe at the speed of light. In the collision, a black hole with a mass of 142 solar masses was formed. This is an extremely important discovery for astronomers. So far, researchers have been able to detect and indirectly observe black holes t...
Next year the Samsung Galaxy S21 could be equipped with an S Pen. The overlap between the Galaxy Note and the Galaxy S lines could continue to increase. Samsung is planning a surprising innovation for the top smartphone of 2021. We expect the Samsung Galaxy S21 (or S30) series. With probably a major innovation. New rumors say that Samsung will then also install an S Pen there. But this is a big problem, as the Galaxy Note series has so far been the only unique selling point on the market with the S Pen. And with the possibly planned change, the Note series from Samsung could become superfluous. As you can read, the Samsung Galaxy S21 Ultra should then make the Note model superfluous. Only there the S Pen should be on board, with the standard version Galaxy S21 and the larger Galaxy S21 + nothing should change. But of course we have to wait and see whether it will really come to that. Perhaps the Samsung Galaxy S21 Ultra will really come with an S Pen. But that doesn’t necessarily m...
