Scientists Find a Key Brain Difference Between Primates and ….

Aug 05, 2022 . The scientists came to the conclusion that there is a species difference between non-primates and primates via the use of five distinct staining techniques and evaluation of more than 34,000 neurons. There are noticeably fewer axon-carrying dendrites on excitatory pyramidal neurons in the outer layers II and III of the cerebral cortex of ....

Dark Energy, Dark Matter | Science Mission Directorate - NASA.

What is dark energy? More is unknown than is known -- we know how much there is, and we know some of its properties; other than that, dark energy is a mystery -- but an important one. Roughly 70% of the Universe is made of dark energy. Dark matter makes up about 25%. The rest - everything on Earth, everything ever observed with all of our instruments, all normal matter ....

Dark Matter Doesn't Exist | Pavel Kroupa » IAI TV.

Jul 12, 2022 . The current cosmological model only works by postulating the existence of dark matter - a substance that has never been detected, but that is supposed to constitute 75% of the universe. But a simple test suggests that dark matter does not in fact exist. If it did, we would expect lighter galaxies orbiting heavier ones to be slowed down by dark matter particles, but ....

What is a brown dwarf? - NASA.

Brown dwarfs are objects which have a size between that of a giant planet like Jupiter and that of a small star. In fact, most astronomers would classify any object with between 15 times the mass of Jupiter and 75 times the mass of Jupiter to be a brown dwarf. Given that range of masses, the object would not have been able to sustain the fusion of hydrogen like a regular star; thus, ....
