What is relativity all about?

Einstein’s theory of special relativity is one of the fascinating scientific advances of the 20th century. Fermilab’s Dr. Don Lincoln has decided to make a series of videos describing this amazing idea. In this video, he lays out what relativity is all about… what is the entire point. And it’s not what you think. It’s not about clocks moving slower and objects shrinking. It’s about… well, you’ll have to watch to see.

@@davidrowe762 THE CLEAR, INTEGRATED, EXTENSIVE, LOGICAL, BALANCED, AND MATHEMATICAL PROOF THAT ELECTROMAGNETISM/energy is gravity: Consider what is E=MC2. TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE. The MIDDLE DISTANCE in/of SPACE AND the full distance in/of SPACE are CLEARLY linked AND BALANCED opposites (ON BALANCE), AS c squared CLEARLY represents a dimension of SPACE (ON BALANCE); AS the stars AND PLANETS are POINTS in the night sky ON BALANCE. This CLEARLY explains and proves TIME dilation AND what is the fourth dimension. CLEARLY, gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites (ON BALANCE); AS the stars AND PLANETS are POINTS in the night sky; AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE). Notice what is the TRANSLUCENT blue sky ON BALANCE in relation to what is THE EYE. What are OBJECTS may fall at the SAME RATE in order to VANISH as part of what is THE EARTH/ground (ON BALANCE). TIME dilation CLEARLY proves that what is E=MC2 is CLEARLY in FULL accordance with TIME AND the fact that ELECTROMAGNETISM/energy is gravity, AS the stars AND PLANETS are POINTS in the night sky ON BALANCE. (Indeed, TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE). Notice what is the orange (AND SETTING) SUN in what constitutes direct comparison WITH what is the FULLY ILLUMINATED (AND SETTING WHITE) MOON. (They are the SAME SIZE as what is THE EYE, AS the rotation of WHAT IS THE MOON then matches it's revolution; AS gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE consistent WITH what is E=MC2, TIME, AND what is THE EYE ON BALANCE.) Consider what is the man (AND THE EYE ON BALANCE) who IS standing on what is THE EARTH/ground. TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE. LOOK directly overhead at what is the BLUE AND TRANSLUCENT sky. (Consider what is invisible AND VISIBLE SPACE in fundamental equilibrium AND BALANCE.) NOW, lava is orange; AND it is even blood red. Excellent. ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE) pursuant to what are E=MC2 AND TIME. Accordingly, ON BALANCE, the rotation of WHAT IS THE MOON matches it's revolution; AND the cosmological redshift proves that ELECTROMAGNETISM/energy is gravity; AS the stars AND PLANETS are POINTS in the night sky ON BALANCE. (Consider TIME AND TIME dilation ON BALANCE, AS E=MC2 is taken directly from F=ma; AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity ON/IN BALANCE). INDEED, GRAVITATIONAL force/ENERGY is proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE; AND “mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY; AND gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE consistent WITH E=MC2 AND TIME. This CLEARLY explains and proves what is the fourth dimension. I have also CLEARLY explained (ON BALANCE) why THE PLANETS move away very, very, very, very slightly in relation to WHAT IS THE SUN, AND I have CLEARLY explained ON BALANCE why the rotation of WHAT IS THE MOON matches it's revolution. ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE). (BALANCE AND completeness go hand in hand.) Excellent. The INTEGRATED EXTENSIVENESS of THOUGHT AND description is improved in the truly superior mind. Again, consider what is the BALANCED MIDDLE DISTANCE in/of SPACE (ON BALANCE) in accordance WITH WHAT IS E=MC2 AND TIME; AS ELECTROMAGNETISM/energy is CLEARLY AND NECESSARILY proven to be gravity (ON/IN BALANCE); AS c squared CLEARLY represents a dimension of SPACE ON BALANCE !!! Indeed, now consider what is THE EYE. It ALL CLEARLY makes perfect sense ON BALANCE. Magnificent !!! By Frank DiMeglio

I love the idea of doing a series on a single topic and I'm excited to see you do it! One thing that I've been thinking about with the second assumption (that the speed of light is the same in any inertial reference frame) is that it should follow from the first assumption. Since the speed of light is a result of two fundamental constants (vacuum permittivity and permeability) and the first assumption is that the laws of physics should hold in any frame, the speed of light follows naturally and doesn't have to be taken as an assumption. I've seen people ask why the second assumption should be valid in the comments a decent bit and think that, though getting to the speed of light through those constants is not particularly intuitive, it does provide a solid basis for the assumption that the speed of light should be the same in any inertial reference frame.

@Inritus618 6 жыл бұрын

Would constants being frame-independent not be implicit in the assumption that the laws of physics are frame-independent?

@Inritus618 6 жыл бұрын

To be clear, I don't disagree that the fact that the constants really are constant is, in fact, amazing. I'm just arguing that it's already baked into the assumption that the laws of physics are frame-independent.
