5 thoughts on “The Fastest Stars in the Universe May Approach Light Speed

  1. Probably haven’t a clue what I’m talking about, but you would imagine two galaxies colliding would result in the termination of life on any inhabited planets coming close to a black hole with their Sun, either by acceleration or being ripped away from the goldilocks zone?

    1. It can happen in region near galactic centers . Rest of the stars like our sun can survive the galactic collision .
      Also there are very less chances of existence of any habitable planets near galactic centers. This is due to high radiation level in that region caused by supermassive black hole .

  2. I find it interesting to be reminded of how fast the sun orbits the Milky Way’s center. 450,000 mph is super fast by earth’s standards. Just the thought of it is mind boggling.

  3. The article ended with the question “Who needs warp drive anyway?”; reflecting on this I came up with the thought that if the human race is still around, wouldn’t they have left the Earth by then anyway? According to our current understanding of Solar evolution, the Sun is expected to have increased in brightness in two billion years from now, as its core runs out of Hydrogen fuel and begins the thermonuclear burning of Helium.

    There are four potential methods human beings (possibly a select few of human beings), may leave the Earth:
    * two involve slower than FTL interstellar drives; a multi-generation star ship or suspended animation (recently a science team, hoping to win the Nonprofit Brain Preservation Foundation’s Brain Preservation Technology Prize, has successfully frozen a rabbit’s brain and thawed it out without any signs of damage to the biological neural network);
    * two involve FTL interstellar drives, such as wormhole travel or warp drive based on the Alcubierre Metric.

    Hitching a ride on a hypervelocity star would certainly require some form of FTL interstellar drive to catch up with the star, whilst matching the trajectory and then land on a habitable planet. Of course hypervelocity stars would need to be surveyed in advance, using robotic probes with FTL interstellar drives to make sure the microbial environment on habitable planets is hospitable to our kind of life.
