Why Interstellar Travel is Physically Impossible.

[Lockback]

Thank God for that. There are already enough creepy things on this earth that bite, sting, and try to eat us.

And worse than that ... Democrats.

I haven't watched the video yet but if he thinks alien technology isn't capable of totally altering the laws of physics as we understand them, I think he's completely wrong.
We can't begin to comprehend what the future could bring.

What about stuff like wormholes or stargates

Wormholes as we understand them collapse virtually instantly (faster than the speed of light).

So, in your quest to use a wormhole to travel instantaneously, you would have to use another method to traverse the wormhole instantaneously.

But a wormhole is the only option for traveling instantaneously.

So you see the problem.

Physically impossible by conventional means, anyway.

This isn't Rick and Morty.

Aliens are not coming to visit.

Correct. Time and distance.

 

[Harry Dresden]

Because they didn't understand the laws of physics well.

We understand that interstellar travel is not practical, precisely BECAUSE we understand the laws of physics.

and what happened when we knew more?...in a hundred years we might know even more about those laws...

Like what? Space time being bent doesn't have gravitational effects? I'm pretty sure nothing is going to change that. Quantum computing and communications... sure. Quantum teleportation of matter, not so much. There is no such thing as a free lunch.

The interesting thing is though, it would take a couple thousand years to get to an habitable planet in a nearby solar system

With enough fuel - or a significantly more efficient propulsion - you could maintain constant acceleration to any destination in the known universe and because of time dilation, arrive there within a single human lifetime.

However, we are at least a century or more away from having that sort of technology.

True, and I hope so. We might. But I think we have a few things nailed. The cosmic speed limit being one of them.

Perhaps the current population of aliens exist in deep, unexplored areas of the oceans. There are many videos of their craft entering and exiting ocean waters as well as credible eye witnesses seeing the same.

people evolve and learn more....some of you people act like this it...nothing more will ever happen...

and one day they might find out a way to get around the physical laws...

who said it was free?....it cost billions to put people up there....

You must be American .

Time on Earth however would be FAR more advanced than your own as the speed of light traveler.

Keep in mind that you have to slow down for the same amount of time that you sped up to get to the destination, so you end up having your ship do a 180 half way through the journey, thereby using its prepulsion to slow down. So if it took 1 year to accelerate up to the speed of light, it would take a second year to slow down to a complete stop.

If you could travel anywhere in the universe why would you ever want to come home?

Bro, i have to be back by April 15th, otherwise the IRS is gonna have a fit!

 

[ShahdagMountains]

What is the point of the known universe?

Or is that a stupid question?

(I’m sure there will be an overflow of goodwill to that last.)
