If we ever managed to explore other galaxies, we'd never know about it...

Thought I would Yogi Berra the topic title.
But seriously, have you thought about it? According to Einstein's special theory of relativity:
1.) If we ever built a craft with the ability to travel close to the speed of light (the only way we're making it to other galaxies)...
2.) Time would pass so much more quickly for everyone on earth, relative to the astronauts on board the ship...
3.) By the time the crew visited and returned from another galaxy - everyone involved in the project would have been dead for generations. I guess the crew could talk to the great-great-great-great-grandkids of the people who designed the mission.
Kinda crazy when you think about it.

A lot more likely we do it with wormholes

Yeah, OP must’ve never seen it.

So, warp machines will exist in the future, but time machines will not.

I actually figured this out after smoking DMT. Sucks that I forgot to write it down.

Well, they kinda do in this example? Except the "time machine" only goes forward, not backward.

It wouldn’t be this way
First off, nothing we “build” will ever be able to reach the speed of light.
Second, according to the “Wait Calculation” any ship we send up in the future would eventually be passed by future generations of 100s or 1000s of years as technology builds upon itself.
Meaning we will never be able to build anything substantial to get us to another galaxy because the technology will never be good enough to get us there

Toss in a flux capacitor and a reverse switch and the problem is solved.
They are now available at O'Reilly Auto.

And if I were on Saturn right now, I would be minutes away from seeing this retard thought.

Get politicians to act as the engineers and astronauts, because laws don't apply to them.

One way near light speed it would take the ship 3500 years to go that 2.5 million.
But still, yeah, not happening.

The closest galaxy Adromeda is 1.5 million light years away. It would take 1.5 million earth years in time to reach it traveling at speed of light
Speed of light would allow exploration of some of our own galaxy but even most if it is thousands of light years away
There is no mode of conventional travel that the human body could endure. Theory of special relativity says that as you approach speed of light your relative mass increases. It would rip you apart if the initial G forces don’t kill you first
Only massless particles can travel at that speed.
I’m not saying it’s impossible but it would require a discovery of a way to defy physics as we currently know it.
I could see AI in our lifetimes being able to pilot a ship with AI robots that can repair and pilot a ship to distant potentially inhabitable plants to search for other life and beam video and communications back to us at incredibly high speeds if we can design a ship to somehow harness a source of infinite energy in space.
But actually finding a way for humans to travel that fast within even a couple decades is a long way off if it’s even possible at all

But instantaneously for the astronaut traveling at the speed of light. His clock would never tick.

NEAR the speed of light it would only take 3500 years to travel 2.5 million light years?

We will likely never be able to accelerate a spacecraft to even 10% of the speed of light but you can work around your problem by only accelerating and decelerating at 1g.
