You're moving very nearly the speed of light with respect to some things in our universe already! With respect to those protons moving around in the LHC at Cern, you are moving at 99.99999% the speed of light. So, can you see yourself in the mirror?
But as Drakkith said, you can't actually travel AT the speed of light.
Do you not know why it is called relativity? You have to say you are traveling near the speed of light relative to some other object. But the mirror you are holding in your hand is motionless relative to you. If you can see yourself in a mirror when you are standing still then you can see yourself in a mirror when you are moving at high speed relative to something else.
1. The Big Idea:
According to Einstein’s relativity, all motion is relative. You can’t tell if you’re moving at a constant velocity without looking outside. But what if there is a universal “rest frame” (like the old idea of the “ether”)? This experiment tries to find out by looking for tiny, directional differences in how objects move inside a sealed box.
2. How It Works: The Two-Stage Process
Imagine a perfectly isolated spacecraft (our lab) moving through space at some unknown speed V...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles.
The Relativator was sold by (as printed) Atomic Laboratories, Inc. 3086 Claremont Ave, Berkeley 5, California , which seems to be a division of Cenco Instruments (Central Scientific Company)...

In Philippe G. Ciarlet's book 'An introduction to differential geometry', He gives the integrability conditions of the differential equations like this:
$$
\partial_{i} F_{lj}=L^p_{ij} F_{lp},\,\,\,F_{ij}(x_0)=F^0_{ij}.
$$
The integrability conditions for the existence of a global solution ##F_{lj}## is:
$$
R^i_{jkl}\equiv\partial_k L^i_{jl}-\partial_l L^i_{jk}+L^h_{jl} L^i_{hk}-L^h_{jk} L^i_{hl}=0
$$
Then from the equation:
$$\nabla_b e_a= \Gamma^c_{ab} e_c$$
Using cartesian basis ## e_I...
