Our Milky Way strips nearby galaxies of star-forming hydrogen

Excerpt from
earthsky.org

Astronomers have discovered that our nearest galactic neighbors are devoid of star-forming gas, and that our Milky Way is to blame.

New observations by large radio telescopes reveal that within a well-defined boundary around our galaxy, dwarf galaxies are completely devoid of hydrogen gas. Beyond this point, dwarf galaxies are teeming with star-forming material. 

The Milky Way galaxy is actually the largest member of a compact clutch of galaxies that are bound together by gravity. Swarming around our home galaxy is a menagerie of smaller dwarf galaxies, the smallest of which are the relatively nearby dwarf spheroidals, which may be the leftover building blocks of galaxy formation.

Further out are a number of similarly sized and slightly misshaped dwarf irregular galaxies, which are not gravitationally bound to the Milky Way and may be relative newcomers to our galactic neighborhood.

Kristine Spekkens is an assistant professor at the Royal Military College of Canada and lead author on a paper published in the Astrophysical Journal Letters. She said:
"Astronomers wondered if, after billions of years of interaction, the nearby dwarf spheroidal galaxies have all the same star-forming ‘stuff’ that we find in more distant dwarf galaxies."

Previous studies have shown that the more distant dwarf irregular galaxies have large reservoirs of neutral hydrogen gas, the fuel for star formation. These past observations, however, were not sensitive enough to rule out the presence of this gas in the smallest dwarf spheroidal galaxies. 

Spekkens said:
"What we found is that there is a clear break, a point near our home galaxy where dwarf galaxies are completely devoid of any traces of neutral atomic hydrogen."
 Bottom line: New observations by large radio telescopes reveal that within a well-defined boundary around our galaxy, dwarf galaxies are completely devoid of star-making hydrogen gas. Astronomers say our Milky Way is to blame.

Schumann Resonance And The Time Speeding Up Phenomenon

Time is actually speeding up (or collapsing). For thousands of years the Schumann Resonance or pulse (heartbeat) of Earth has been 7.83 cycles per second, The military have used this as a very reliable reference. However, since 1980 this resonance has been slowly rising. Some scientists believe that it is rising faster than we can measure seeing as it is constantly rising while measuring.This is from a member of the Physics Forum:"The universe is expanding; interstellar distances [...]
