The study of black holes over a 20-year period revealed that the speed of time at the beginning of the Universe was five times slower than what it is now.
Researchers at the University of Tokyo combine their expertise in robotics and tissue culture to create a robotic finger that can be controlled. The living tissue is then applied on top of it. Living cells and organic material are grown on the robotic digit for optimal strength and shape. The finger’s skin is soft, and it can even heal by itself. It could be used in applications that need a gentle touch while also being robust. The team hopes to incorporate other types of cells in future iterations to give devices the same ability to feel as we do.
Albert Einstein demonstrated decades ago that space and time are inseparable. The expansion of the Universe has caused events after the Big Bang to appear to be slower. It turned out that time moved much slower at the beginning of the Universe.
What we Know
Scientists from the University of Sydney came to this conclusion. The study lasted two decades. They observed 190 supermassive active black holes in the centre of galaxies during this period. Quasars are intensely radiated black holes.
