(You, of course, indicating its impact on the Earth and not necessarily you on a personal level.)
By essentially sapping energy from an orbital system, gravitational radiation makes orbits more circular and continuously decreases their radii. Overall angular momentum decreases, as this too is essentially stolen by radiation. The decrease in the radius of orbit is given by the following equation:
Substitution of the Earth's and Sun's masses for m1 and m2 tells us that the rate of our orbit
The observation of interactions is basically the foundation of science and physics, but often times this observation directly alters the phenomena being observed. This concept is aptly named the observer effect.
In circuits, the voltage and current can be measured by the use of voltmeters and ammeters, respectively. However, the placement of these devices into the current alter the actual voltages and currents of these circuits. This is why voltmeters are very high in resistance and wired in
Relativity, as we know, explains the intimate connections of space and time, since they are essentially components of one larger entity, the spacetime continuum.
One of the more elusive byproducts of this theory is the concept of gravitational waves. To explain, first understand that the spacetime continuum has curvature, and this curvature is directly affected by the mass of an object. For instance, large masses like planets will actually cause spacetime to "bend" around it.
And gravita
My previous blog post took a look at the far future - a timeline of events predicted to occur in our known universe assuming it exists infinitely (no Big Crunch).
Well, if it exists for an infinite amount of time, there will logically be an infinite number of physical occurrences/interactions. So theoretically, though seemingly improbable, there could potentially be the formation of what's known as a Boltzmann brain.
Entropy is increasing in our universe as it expands - chaos - and accordi
We humans are drawn to the unknown and the mysterious. And what's more mysterious than black holes? Not much.
An event horizon (a.k.a. a point of no return) is a boundary in spacetime where an outside observe cannot be affected by anything beyond it. In other words, a gravitational pull is so strong that nothing can possibly escape it. Light emitted from beyond the black hole's event horizon can never reach an observer outside of the horizon.
If you, an observer, are looking towards one of
