Why we cannot go faster than light - BBC REEL

The Universe has a speed limit and it seems there is no way around it.

The suggestion that you could get to any part of the universe in one lifetime ignores the fact that space itself is expanding, in some areas faster than the speed of light

[johnnyjk]

They are just making claims without substantiating any real science. This video is about 40% accurate, basically the buzz feed of physics

[DMSJagXK]

As an object moves faster, its inertial mass increases and therefore as it gets faster, a greater amount of energy is needed for each additional 1m/s increase in speed. There isn’t enough energy in the Universe to get even a single electron to the speed of light.

I thought this was great how I wish my oldl days at school explained things in such a practical

[theob]

Before we broke past the speed of sound, scientists said you couldn’t and you’d hit a wall of air.
Is this not history repeating itself?

[jasonhacker]

In star trek, they don't actually travel faster than light. They use warp travel, so the light speed limit doesn't mean that star trek warp travel cannot happen

[valentinaselektrikas]

Star trek invented warp engines to brake theoretical light-speed limit by bending space. To bend space you need huge mass, for example like a planet mass.

[shukitheconscious]

I'm pretty sure back then they thought sea and air travel were impossible until they achieved it. It's possible, we just don't know how yet.

[TommyMissus]

3:50 faster than light wouldn't be going back in time tho? Wouldn't you just SEE things in reverse? Doesn't mean they're going back in time it just appears to be to our perspective

[johndevine]

It does not exist. You are confused. Electro magnetic levitation exists. With electromagnetic levitation one can speed a ship, or anything else, over obstacles at what might appear to be something nearly instantaneous, so called ‘light speeds’.

[drjones]

I kinda regret wondering about this, I’ll just accept you can’t because it’s complicated….

[greyface]

Saying what we cannot do in science is the opposite of a explorative scientific mind. Saying we cannot go faster then light right now in this time is true, but saying it is impossible is closed minded. Who are you to say what we can and cannot do in thousand or a million years.

“Nothing moves faster than light”

Quantum Entanglement enters the chat

[MicrowaveBackground]

Why's everyone swaying like they're pissed

[Stopinvadingmyhardware]

Dude, seriously, why do you want to? There’s no where else to go, and if humans are any indication of how brutal existence is, you’re not going to survive any “alien” encounter.

[OperationDx]

In Star Trek they where not traveling using conventional means. The warp drive created a warp bubble that bypassed the space / time problem. However this is not been proven possible and would also require a massive amount of energy. Like the building blocks of the universe kind of energy.

[mastergems]

Technically moving at the speed of light is one aspect. We have bending time and space to decrease distance.
We have matter transportation which is another.

[fogh]

I would like to hear more about the shadow puppet and how it goes faster than light. I am not convinced this is true, think about it in a slower setting, like if you are watering the moon with a giant watering can and put fingers under the stream to make water “shadow” puppets, the drops will not fall where your hand is, moving it around will let drops fall, but these drops would have to travel from the giant can to the surface - taking time. Now think of the water drops as being darkness in the shadow puppet example, how can darkness travel faster than light?

[buckchile]

So that's why I can't hit the bed before the light goes out

[barabbasrosebud]

Totally wrong. The reason why you can't go faster than light is very simple i.e. the speed of light in vacuo or "c" (~670, 000, 000 mph) is the speed at which the universe is refreshed, linearized.
