Do the basic forces of the universe still move? Do particles exist? Is the atom still in motion? Does the gene still exist? Do various molecules still exist? Are cells still alive? Do people still exist? Existence, does it still exist??
Chemistry is all around us in our daily lives. It explains why food cooks, cars run, and plants grow. By studying chemistry, we learn how things work at a microscopic level. From the smallest atoms to large molecules, chemistry helps us understand the building blocks of the world. ...
But where does space begin and, more importantly, what is it? Space is an almost perfect vacuum, nearly void of matter and with extremely low pressure. In space, sound doesn't carry because there aren't molecules close enough together to transmit sound between them. Not quite empty, bits ...
This first stage produces simple molecules, which can then recombine to make more complex molecules if this astonishing experiment is successful. What we're going to do now is warm the system a little to see what the ice does.第一步产生简单的分子，如果这个惊人的实验成功的话，这些简单的分子就...
Interstellar space is the area between the stars, but it is far from empty. It contains vast quantities of neutrinos, charged particles, atoms, molecules, dark matter and photons ranging from the highest-energy radiation to the sluggish light of the cosmic microwave background (CMB) albeit rathe...
