Is a change of temperature a chemical reaction? A change in temperature is characteristic of a chemical change. If temperature increases, as it does in most reactions, a chemical change is likely to be occurring. This is different from the physical temperature change. During a physical temperature change, one substance, such as water is being […]
How do neutrons kill?
How do neutrons kill? Since neutrons are scattered and absorbed by air, neutron radiation effects drop off rapidly with distance in air. The intense pulse of high-energy neutrons generated by a neutron bomb is the principal killing mechanism, not the fallout, heat or blast. Does a neutron bomb exist? A neutron bomb is actually a […]

Why is light red shifted?
Why is light red shifted? Light behaves like a wave, so light from a luminous object undergoes a Doppler-like shift if the source is moving relative to us. However, to be accurate, the red shifts observed in distant objects are not exactly due to the Doppler phenomenon, but are rather a result of the expansion […]
