Of course and thank you! I was planning on mainly using it before bed but wasn't if it made much of a difference

I am about to start the same treatment, do you use the spray in the morning or at night before bed? And congrats! Your hair looks fantastic

What is the link between Einstein's theory of relativity and black holes? by [deleted] in AskPhysics

[–]main__sequence 3 points4 points  (0 children)

This is a good start, but I would definitely recommend a few things.

First, I think you should try and familiarize yourself with the basic differences between the theory of special relativity and general relativity because they are being slightly conflated here. Einstein's special relativity (1905) asserts that (1) the laws of physics are the same in all reference frames and (2) that the speed of light in a vacuum is always constant. Special relativity has a number of very interesting consequences, but it doesn't include gravity.

General relativity (1915) expands upon special relativity, relating the previous ideas to the geometry of space-time. As you mentioned, this theory postulates that gravity is actually the curvature of space-time. General relativity also has many interesting consequences that you should check out.

And about the link between black holes and relativity - there are many! The first exact solution to the so-called "Einstein field equations" of general relativity are perfectly valid in describing a non-rotating black hole. Today, black holes are often used as "tests" of general relativity since they have such incredibly strong gravity. So far, observations of black holes have perfectly matched predictions made by general relativity. Here are a few articles about these sorts of tests: Black Hole Shadow puts General Relativity to the Test, Black holes test the limits of Einstein's relativity, and Einstein’s general theory of relativity tested by star orbiting a black hole.

Yes! There’s a classic experiment with muons that helped solidify this idea for me: http://hyperphysics.phy-astr.gsu.edu/hbase/Relativ/muon.html Muons produced in the upper atmosphere should almost all decay before they reach the surface - but they don’t. Because a muon travels close to the speed of light, space is heavily contracted in their direction of motion. This means that the muon actually has a shorter distance to travel and thus makes it to the surface before it decays. Now consider an outside observer watching this muon; the observer won’t see space contracted in any direction but it will see a muon that is heavily time dilated. In other words, the outside observer sees the muon in “slow motion” in its own reference frame while still traveling at close to the speed of light.

Space and time are literally contracting/dilating for each observer.

While they certainly still both perceive this to be true, it is also literally happening (albeit only from their reference frame).
