Time travel, long imagined by writers and dreamers, is not as far-fetched as you might believe. Sure, it seems fantastical and improbable — the imaginings of which are only meant for postulations and movies — but astrophysicists do it all the time.
And so did Hope College freshman Jeff Engle in the summer of 2016 at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. All it took was expensive, highly powered, one-of-a-kind stellar equipment called the Fermi Gamma-Ray Space Telescope. That and funding and guidance from the Hope College physics department and Professor Dr. Peter Gonthier.
In the ion beam lab, I am using in-situ TEM to study the effects of radiation damage on materials being considered for nuclear applications. We can irradiate TEM samples with various heavy ion beams (e.g. Au, typically ~2 MeV range for in-situ experiments, used to simulate neutron irradiation damage, for example) and gas (e.g. He, typically keV range) beams and take videos during the irradiation to study damage evolution as a function of time/damage dose/gas concentration.
