    Do we need an alternative theory of gravity if it’s turns out that dark
    matter doesn’t exist?

    “with all the problems here on Earth, why should we bother going to space?”
    – Because the solutions to our problems (either technology or resources)
    are out there beyond the gravity well of this mudball.
    “why should we let celebrities go to space?” – We aren’t ‘letting’ them;
    they are spending their own resources (which we gave them by paying
    them/buying tickets, etc.) to go. It’s their money, not yours.
    Thus endeth the rant – I really hate the ignorance embodied in those two

    At 34.10 Ramin skibba explains the difference between star clusters and
    dwarf galaxies and he states that star clusters have no dark matter.
    That had me a bit baffled as we are trying to detect dark matter (wimps)
    here on Earth with detectors only a few metres across yet he states there
    are entire star clusters that do not have any at all.
    This gives me the impression that the Earth and it’s surrounding space is
    enveloped in a kind of dark matter bubble whereas these star clusters are
    not.Is that correct?
