Mass and energy when traveling at near the speed of light

Click For Summary
Objects cannot reach the speed of light because their mass increases as their velocity approaches that limit, requiring infinite energy to accelerate further. Light, despite having no mass, is influenced by gravity due to the curvature of spacetime, as described by general relativity. This means that gravity affects all forms of energy, including light, even though they do not possess mass. The phenomenon of light bending around massive objects, like black holes, illustrates this interaction. Understanding these concepts is crucial for grasping the complexities of physics at relativistic speeds.

I was reading about the speed of light and it says that no object can travel at the speed of light because the mass of the object increases as it moves faster. How is that possible?

Also if light travels at such a speed because it has no mass, then why does light get affected by gravity near black holes? Doesn't an object need mass to feel the effect of gravity?

What do you mean by "How is that possible?" We observe that it happens, so evidently it's possible.

Thread 'EPR revisited'

In an inertial frame of reference (IFR), there are two fixed points, A and B, which share an entangled state $$ \frac{1}{\sqrt{2}}(|0>_A|1>_B+|1>_A|0>_B) $$ At point A, a measurement is made. The state then collapses to $$ |a>_A|b>_B, \{a,b\}=\{0,1\} $$ We assume that A has the state ##|a>_A## and B has ##|b>_B## simultaneously, i.e., when their synchronized clocks both read time T However, in other inertial frames, due to the relativity of simultaneity, the moment when B has ##|b>_B##...
