Blog 4: Explaining Relativistic time dilation
Time seems to be one of the only immutable aspects of the universe, besides death and taxes. Many people believe that the passage of time is altogether unstoppable and unyielding. And for most intensive purposes, they are right. Indeed, time is our most precious resource and one that many of believe we have an extremely […] Continue reading

Blog 1: size of the universe
The size and scale of our universe is nearly incomprehensible. While many comparisons have been formulated to describe certain cosmological distance (such as from the Earth to the Moon, and so on), I believe that only one can even claim to do justice to the size of the universe. To gain even a slight comprehension […] Continue reading
The Unimaginable Nature of Space-Time
Most depictions of the space-time continuum display it as a two-dimensional plane in three-dimensional space. In such a model, objects make indents in the plane based on their gravity, with more massive objects having larger indents. This model is helpful to display how gravity works, but it doesn’t capture the whole picture. The planar model […] Continue reading
Black holes and spacetime | blog post II
Black holes are areas in spacetime where the gravitational force is so strong that nothing can escape. This includes forms of electromagnetic radiation like light. Current general relativistic models depict black holes as a taking on spheroid shapes, with an interminably long “tail” leading to its point of singularity. Singularity is a geometric point where […] Continue reading

Infinity into infinity OR an edge never to be discovered?
It’s been known for a while now that the universe is expanding, but the real question is, what is it expanding into? Well, the answer is no body really knows. Einstein’s theory of relativity makes it possible for the universe to be expanding into anything, including into itself. Because of the vast size of the … Continue reading Infinity into infinity OR an edge never to be discovered? Continue reading
Gravitational Waves and Extra Dimensions
The existence of dimensions beyond the three spatial and one temporal we experientially inhabit in our current model of spacetime has been a longstanding discussion touched on by various physicists and the scientific community. It has been suggested that gravity would propagate throughout these other dimensions, a thought brought about in attempts to somewhat unify … Continue reading Gravitational Waves and Extra Dimensions → Continue reading
How Gravity Affects Space-Time
One of the more interesting (and more confusing) concepts we’ve learned thus far in the Solar System is the bending of spacetime. As can be seen in the figure below, massive objects with gravity (such as planets or stars) have the unique property in that they can bend the spacetime “grid” around them. Before you […]

White Holes
A white hole is a hypothetical region space time which cannot be entered from the outside.” The idea of a white hole is essentially that is the opposite of a black hole. A “worm hole” is the connection from black hole that consumes all matter around it, and send its through a warp in space […]

Trous Noirs And trous noirs
For an explanation of the title, see the link at the end. If you are seriously, irreconcilably frustrated by your significant other (or lack thereof) and you never want to see your significant other (or yourself) ever again, please accept a sincere piece of advice from me: Do not- I repeat: DO NOT throw them(or yourself) in […]
