Is Earth heavier than we think? GPS satellites suggest a halo of dark matter is surrounding our planet
Ever since scientists have theorised that dark matter exists, concrete evidence of the elusive substance has continued to confound them. Now, data from a number of GPS satellites suggest that a halo of the strange matter may be surrounding Earth, causing our planet to be heavier than first believed.
From his calculations, Professor Ben Harris from Texas University claims this halo could affect the Earth's gravity and that the planet could be 0.005 and 0.008 per cent heavier than the mass established by the International Astronomical Union.
Dark matter is considered crucial to theories explaining how the universe is expanding and how galaxies interact. It is thought to make up 27 per cent of the universe, but despite huge amounts of funding and research effort, experiments have so far failed to confirm its presence.

Kirk takes the Enterprise into the Dark Matter Halo which is collapsing , threatening to crush earth. Spock and Scotty engineer a reverse polarity time warp drive which sends the crew into a parallel universe where Klingon technology has solved the riddle of Calico Tribbles.
