Why nothing can travel faster than light? Explained 🔥

Special relativity is an explanation of how speed affects mass, time and space. The theory includes a way for the speed of light to define the relationship between energy and matter — small amounts of mass (m) can be interchangeable with enormous amounts of energy (E), as defined by the classic equation E = mc^2.

Special relativity applies to "special" cases, mostly used when discussing huge energies, ultra-fast speeds and astronomical distances, all without the complications of gravity.

Einstein officially added gravity to his theories in 1915, with the publication of his paper on general relativity.

As an object approaches the speed of light, the object's mass becomes infinite and so does the energy required to move it.

That means it is impossible for any matter to go faster than light travels. This cosmic speed limit inspires new realms of physics and science fiction.

This understanding of mass and energy makes it a little easier to understand one reason why we can never reach the speed of light. The energy of a particle diverges to infinity as it approaches the speed of light.

Since we can never have infinite energy for a particle, the speed of light cannot be reached. Since an object has infinite kinetic energy when it approaches the speed of light, it therefore has infinite mass as well.

Explained in simple language...in less than a minute..exceptional explanation.

[MeetGadhavi]

Jokes on you my mom's sandel travels at the speed of light

[dougg]

I’ve been reducing my mass and I’m still slowing down. Maybe more light… beer

[neutralmind]

i watched many videos but this short made me understood

[xTriton_]

*Fun fact:* Expansion of the universe is faster than the speed of light, yes. But it's not an *object.* It's just a phenomenon and nothing is actually _moving_ during this.

This comments section makes me lose my braincells 💀

Its filled with kids acting like Ph.Ds in Physics.

[rahimrkf]

So if I run really fast I will start gaining wieght

[godspeed]

Barry Allen has left the chat at normal speed.

[kellimihalic]

You just reduced years of physics down to mere seconds. Really, honestly, I thank you.

[anis.niraula]

Imagine travelling in speed of light and crash with just a tiny astroid.

[xTriton_]

For some reason, people keep bringing in "Speed of Mind" and claiming it's faster than light.
I have a quote for these people:

*Half knowledge is more dangerous than ignorance.*

[xdcharot]

"spaceship can travel speed of light it's impossible"


Spaceship in the future: let me introduce myself

[thib]

This is a great explanation, short but very understandable!

Object speeding up gains momentum, e=mv2 not mass

[marcoschlimper]

"The faster something with mass travels the more mass it gains", by the time that it reaches speed of light it will have exaggerated amounts of mass. So where does the additional mass come from? What form of mass is it? Is it merely built up particle resistance (an example would be super sonic planes breching the sound barrier and causing a Sonic Boom). If so, can that particle resistance be harnessed and converted to a form of usable energy to dissipate the resistance and speed up the moving object at the same time? Resistance by nature is something that is impeding movement, which means a collision of particles, (think LHC) particle collisions can cause a release of energy which is detectable, and if something is detectable it would also be collectable.

Not only that, time moves faster the more you accelerate meaning that it would take an infinite amount of time to accelerate to that speed
