• If gravity propagates at the speed of light in a vacuum, and the speed of light through other mediums is lower than c... then can the speed at which gravity propagates also be slowed? https://www.reddit.com/r/askscience/comments/7nnnc0/if_gravity_propagates_at_the_speed_of_light_in_a/ 9 comments 2/1/2018 askscience
• Scientists finally have an explanation for why aurorae cause "speed bumps" that can slow down spacecraft when our Sun’s activity is highest, causing them to fall closer to Earth. The find comes thanks to a rocket launch into the northern lights over Norway. http://astronomy.com/news/2019/04/speed-bumps-from-auroras-can-slow-down-satellites 4 comments 24/4/2019 space
• Researchers discover new way to turn electricity into light, using graphene.

• Tachyons: Hypothetical particles that travel faster than light. They would experience time in reverse. They would have imaginary mass - as in square root of -1. Adding kinetic energy would slow them down; an infinite amount of energy would be needed to slow them to the speed of light. http://www.armaghplanet.com/blog/what-ever-happened-to-tachyons.html 13 comments 17/10/2014 space
• Since photons do not experience time themselves because they are going at the speed of light according to relativity. But since gravity pulls on light, thus slowing it down, does that mean all light experiences time? https://www.reddit.com/r/askscience/comments/74q0fk/since_photons_do_not_experience_time_themselves/ 14 comments 6/10/2017 askscience
• Light Pulses Change Speed in a Plasma. Note( key statement): Where the paths of the two beams crossed, the horizontal component of the second laser pulse slowed in response to a change in the plasma’s refractive index. https://physics.aps.org/articles/v14/s60 13 comments 1/8/2021 science
• Researchers have developed a way to control the speed of light. Not only can they speed up a pulse of light and slow it down, they can also make it travel backward. That could one day lead to more efficient optical communication & prevent information loss https://www.nature.com/articles/s41467-019-08735-8 5 comments 5/4/2019 science
• Researchers studied how light can be used to observe the quantum nature of an electronic material. They captured light in graphene and slowed it down to the speed of the material's electrons. Then electrons and light started to move in concert, manifesting their quantum nature at a large scale http://science.sciencemag.org/content/357/6347/187 25 comments 14/7/2017 science
