It may surprise you to know that we can still observe the Big Bang, in a way! In fact, every time you accidentally flip to TV static, you're watching a fragment of it right there! To find out more about this echo of the spawning of the universe, join us online on Wednesday, August 12 at 6:30pm. From that first, immense explosion to now, Dr. Adam Hincks will be delving into the details of the cosmic microwave background radiation! As always, everyone is welcome!
