Travel to Andromeda? And back?

[JeffKeryk]

With all the stuff going on today, I thought I would like to add a little perspective... Professor Cox for the win!

Didn’t watch the video but the light you see from Andromeda left there 2.5 million light years ago so…..

 

[wavinwayne]

If you went there and back at light speed, at least 4 million years would have passed on the Earth, and my wife still wouldn't be ready to go.

Bring a lunch, as they say...

I just wish the Amazon delivery guy would hurry up and get here.

If Kelinda is there, I’m willing to make the journey.

Voyager 1 is almost 1 light-day away from earth in a trip that's taken almost 50 years. Not sure how I feel about that.

Prof.Cox is excellent with his down to earth ( don’t mind the pun) explanations. He is featured in BBC Earth, a series available on the BBC channel.

I've seen him talk and lecture. Will see him again in January.

I've seen a couple of series he hosted/narrated. BBC made. maybe History Channel re-ran them. Not sure.

Only if she kept her human form - the Kelvans’ original form was a multi-tentacled creature of limited perception - but she chose well in adopting a human form.

She was hot!

Impossible to travel outside our solar system >>> E=MC^2

One thing that impresses me about him is his ability to recite the same information for the ~1000th time and still have an enthusiasm for it.

Two Voyagers are already outside our solar system. So that equation doesn't equate.

He expresses enthusiasm in a low key manner and doesn't need to make faces, wave his arms, and act excited, unlike a certain youtuber oil expert.

 

[KrisZ]

Well, he doesn't elaborate how we measured the 7000 times perceived distance and time reduction when traveling at the speed of light, so I'm skeptical of the claim. But even if it's true, we know that nothing with mass can travel at the speed of light.

Also, some of the shows on BBC Earth will overlap on the material, with the same video sections. Still, it reinforces the info.

 

[Snagglefoot]

My favorite episode he is on is when he talks about the moon Titan orbiting Saturn, he points out that when the sun starts expanding towards the end of its life, it will warm up Saturn and Titan, and Titan will be in the " life zone" for billions of years, potentially being a place to hang out until the end of the solar system.

Why would this relationship between energy and matter prohibit travel outside the solar system?

As has already been pointed out - we have two space craft, built in the 1970s, that have already traveled outside the solar system.
