Our solar system orbits around the Milky Way roughly every 200-250 million years and researchers at Cardiff University suggest that periodically, in cycles estimated at every 37 million years or so, we encounter dangerous ‘speed bumps’ with life-extinction-causing asteroids.

You can start by signing this petition to build a Gen 1 Enterprise and getting as many people to sign it as possible (https://petitions.whitehouse.gov/petition/assign-nasa-do-feasibility-study-and-conceptual-design-gen1-uss-enterprise-interplanetary-spaceship/DB07k8jF?utm_source=wh.gov&utm_medium=shorturl&utm_campaign=shorturl).

I agree with Mr. Pellletier - we need to be giving more attention to low-probability but catastrophic events. Also like the idea of building the Enterprise and have signed the petition.
Something about this article reminds me of the discovery channel or articles in new age rags - replete with misstatements and schlock like that from Zecharia Sitchin and his planet X in its impossible 3600 year orbit.
Asteroids are residents of our solar system, they aren’t extra solar invaders. We must have passed through lots of galactic arms in our 220 million year orbit of the galaxy many times as the sun oscillates below and above the plain of the galaxy like every other star.
Our solar system is exposed to cosmic rays ALL THE TIME, and the only minor danger points arise when the magnetic field goes through one of it’s flips, which have had no effect on the flora and fauna that is detectable.
Our Galaxy does not hit rough spots as it is not moving fast enough but other smaller galaxies routinely collide with it. Perhaps the author is confusing Galaxy with Solar system.
