First, the model of electrostatic force is demonstrated. As depicted in Fig. 1, dominated by the photoelectron effect induced by solar ultraviolet and x-ray radiation, the spacecraft and lunar ...

We suggest that there should be a minimum electromagnetic radiation frequency in the Hubble sphere and that this seems to be directly linked to the Hawking Temperature and our recent discovery that ...

Scientists are constantly pushing the boundaries of knowledge and possibility. Over the last year, research teams around the world have broken ground, experimented, invented, and pushed us a little ...

With modern seismic tomography, Earth scientists have discovered that above Earth's core-mantle boundary (CMB), about 2,900 ...
