Yes, time travel is possible. One of man’s most fascinating and controversial fantasies is more than just science fiction: it’s real…
Randall Munroe of XKCD put together this fascinating chart of the “ionizing radiation dose a person can absorb from various sources;” from using a cell phone to CT Scans to being at Chernobyl and Fukushima when disaster struck.
Munroe received help from Ellen, a Senior Reactor Operator at the Reed Research Reactor, and you can find a list of the sources used here.

“It’s for education purposed only. If you’re basing radiation safety procedures on an internet PNG image and things go wrong, you have no one to blame but yourself.”
Don’t be frightened, but these cosmic snipers are real! But just what would happen if one of these bursts takes a shot at Earth?
Kurzgesagt-in a Nutshell has a new video called Death From Space. It explains Gamma-Ray bursts: How they work and why they form.
Photonicinduction is an electrical engineer who has been pushing electrical appliances to their limits for our viewing pleasure since 2008, but even he seems to be impressed by the subject of his latest video: a 20,000 Watt light bulb.
20,000 Watt Halogen lamp used for large scale films sets, we get a close up look and full power test.
This video is about gravitational waves in the weak field limit as discovered by the LIGO collaboration, explained by parallels to electromagnetic radiation, sound waves, water waves, etc.
