A Trip from the Sun to Jupiter at the Speed of Light. Bring a Sandwich.
Watch what it might look like to travel from the sun to Jupiter at the speed of light.
Douglas Adams said it in Hitchhiker’s Guide to the Galaxy, and he wasn’t wrong:
Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.
Alphonse Swineheart has made a video that shows what a “quick” trip from the sun to Jupiter would be like for a photon. It’s just a short hop: just 807 million kilometers, halfway across our solar system. By “quick,” we mean at the speed of light, the greatest speed at which many believe anything can travel.
One thing “quick” doesn’t mean here is “fast.” It takes:
Watch this in full screen if you can.
When you consider that this is just making our way halfway across our own celestial neighborhood, you have to wonder how interstellar travel would be possible at all. Swineheart says he cheated a little by not considering how relativity might bend space and so on. Even so, traveling to other solar systems and galaxies would clearly require some means of getting from place to place we haven’t yet discovered.

Upstreamism advocate Rishi Manchanda calls us to understand health not as a "personal responsibility" but a "common good."
- Upstreamism tasks health care professionals to combat unhealthy social and cultural influences that exist outside — or upstream — of medical facilities.
- Patients from low-income neighborhoods are most at risk of negative health impacts.
- Thankfully, health care professionals are not alone. Upstreamism is increasingly part of our cultural consciousness.
The Bajau people's nomadic lifestyle has given them remarkable adaptions, enabling them to stay underwater for unbelievable periods of time. Their lifestyle, however, is quickly disappearing.
- The Bajau people travel in small flotillas throughout the Phillipines, Malaysia, and Indonesia, hunting fish underwater for food.
- Over the years, practicing this lifestyle has given the Bajau unique adaptations to swimming underwater. Many find it straightforward to dive up to 13 minutes 200 feet below the surface of the ocean.
- Unfortunately, many disparate factors are erasing the traditional Bajau way of life.
The Canadian professor's old-school message is why many started listening to him.
- The simplicity of Peterson's message on suffering echoes Buddha and Rabbi Hillel.
- By bearing your suffering, you learn how to become a better person.
- Our suffering is often the result of our own actions, so learn to pinpoint the reasons behind it.
An innovation may lead to lifelike evolving machines.
- Scientists at Cornell University devise a material with 3 key traits of life.
- The goal for the researchers is not to create life but lifelike machines.
- The researchers were able to program metabolism into the material's DNA.
