Doctor Who Gets One Piece Of Time Travel Exactly Right According To Scientists

Posted by in categories: biotech/medical, time travel

Astrophysicist Geraint Lewis of the University of Sydney in Australia recently authored a study about time dilation and said that Doctor Who’s description of time travel is accurate, as we truly don’t yet understand the limitations of time (via Reuters).

Sci-fi shows like Doctor Who can usually rely on the audience’s suspension of disbelief when diving into heady concepts, and the science doesn’t always have to be accurate — though it is much cooler when a show gets the science right. Apparently, the long-running BBC series can take pride in the fact that the Doctor’s description of time as ‘wibbly-wobbly, timey-wimey stuff, is co-opted by real-life astrophysicists.

In other words, theoretical concepts like time travel and warp drives could be possible, or they may not be. Maybe a Time Lord out there uses a British police box to travel through time. Okay, so Doctor Who probably isn’t right about that part, but there technically is still a chance that it is!

The time machine: How life on a Navy submarine distorts your sense of space and time

Nothing prepared me for the disconnection from Earth that distorted my perception of time while submerged.

Before the Big Bang 11: Is the Universe a Time Machine?

Posted by in categories: cosmology, evolution, quantum physics, time travel

What happened before the Big Bang? In two of our previous films we examined cyclic cosmologies and time travel universe models. Specially, the Gott and Li Model https://www.youtube.com/watch?v=79LciHWV4Qs) and Penrose’s Conformal Cyclic Cosmology https://www.youtube.com/watch?v=FVDJJVoTx7s). Recently Beth Gould and Niayesh Afshordi of the Perimeter Institute for Theoretical Physics have fused these two models together to create a startling new vision of the universe. In this film they explain their new proposal, known as Periodic Time Cosmology.

Mammalian Tree of Life Redefined: Genomic Time Machine Traces Back 100 Million Years of Evolution

Posted by in categories: biotech/medical, evolution, time travel

The research uses the genomes of 241 species.

A species is a group of living organisms that share a set of common characteristics and are able to breed and produce fertile offspring. The concept of a species is important in biology as it is used to classify and organize the diversity of life. There are different ways to define a species, but the most widely accepted one is the biological species concept, which defines a species as a group of organisms that can interbreed and produce viable offspring in nature. This definition is widely used in evolutionary biology and ecology to identify and classify living organisms.

Time Travel and it’s Possibility

Posted by in categories: physics, robotics/AI, time travel

Created using Paragraph ai.

Time travel has long been a popular theme in movies, but scientists believe that the concept of time teleportation is unlikely in reality. However, they do not dismiss the possibility of time travel altogether. The laws of physics suggest that time travel may be possible, but the details are complex.

Physicists explain that traveling to the near future is relatively simple, as we are all doing it right now at a rate of one second per second. Additionally, Einstein’s special theory of relativity states that the speed at which we move affects the flow of time. In other words, the faster we travel, the slower time passes. Furthermore, Einstein’s general theory of relativity suggests that gravity also impacts the flow of time. The stronger the nearby gravity, the slower time goes.

Time Perception & Entrainment

Posted by in categories: chemistry, neuroscience, time travel

In this episode, I discuss how our brain and body track time and the role that neurochemicals, in particular dopamine and serotonin, but also hormones such as melatonin, allow us to orient ourselves in time. I review the three types of time perception: of the past, of the present, and the future, and how dopamine and serotonin adjust both our perception of the speed of the passage of time and our memory of how long previous experiences lasted. I also discuss circannual entrainment, which is the process by which our brain and body are matched to the seasons, and circadian (24 hours) entrainment, both of which subconsciously adjust our perceived measurement of time. I explain the mechanisms of that subconscious control. And I cover the ultradian (90 minutes) rhythms that govern our ability to focus, including how to track when these 90-minute rhythms begin and end for the sake of work and productivity. I include ten tools based on the science of time perception that you can apply to enhance productivity, creativity, and relationships in various contexts.
