The reason why I had twin Sam travel at light speed around earth orbit while twin Tom stayed on earth was to ensure communication stays intact between the two. Now provided paradox 1 about twin ageing holds true for Sams 1 year in space Tom will age by ~7.09 years on earth. How would...

Is it feasible for a mirror antimatter universe to exist?

Two twins, one Sam travels to space and one Tom stays behind on earth. No Sam did not travel to the nearest star but went in orbit around the earth at near speed of light for 1 year. Both had facial cam and saw each other all the time as communication is good between earth and the orbit, how...

While asking this question I was as well considering the movement of the galaxies while expansion is happening. Our visible universe has moved along with us (maybe the most of it) while others who were formed along with our Milkyway may have moved in other directions and today we are not able...

Yes it is collisions or as well as massive bodies bending and dragging space along when they move. Like satellites revolving around planets, planets revolving around the sun, Stars in galaxies revolving around a center which is possibly a giant black hole thus we can say galaxies are also...

While this is a continuing thread, I just want to still bring in the perspective from #21 (my sincere apologies for any repeat) Every object that we know in the universe (as of date) has motion, they spin on their axis and as well revolve around larger objects in certain orbits. Even the...

Or maybe we just don't know yet for sure.

IF travelling near speed of light can actually help prevent ageing then Humanity will better survive as humans this way rather than becoming X-Men, Cyborgs, Metaverse Avatars with AI or any other alternatives still not researched. The question in the initial thread was about the possibilities...

Thank you @billslugg. Are we able to observe any such motion today for Superclusters like Virgo, Laniakea, Shapely or others?

Is it possible for Superclusters to have their own spin or some sort of movement together as a cluster?

If in near future we are able to travel at speeds of light, can a frequent traveler (Astra-naut) between the Star systems (say our Sun and any nearest Star) stay relatively younger compared to people on Earth (or life on other Star Systems)? Will such frequent travels be another way of staying...

Is Gravitational Wave the same as Gravity?

I guess in this initial thread "Spin" refers to the rotation of Universe around its own axis hence #21 is question around that.

This is an interesting thread not sure if conclusive yet... just curious on the point from @Unclear Engineer if the axis around that we spin (if true) is not passing through earth or let say not anywhere near visible universe and we at earth are positioned in such a way that we always see stars...

Hi Cat, I was only referring to your reply #7... If I understand it right, we have three possible known ways that allows Gravity to exist: 1. Spinning Objects simulate gravity effects, this theory should allow us to create artificial gravity in space 2. Einstein theory that massive objects...
