What is the Universe Expanding Into?

By popular Space Fan request, I offer this video to help answer some of your questions regarding the expanding universe. Many of you consistently ask: If the universe is expanding, then what is it expanding into?

This concept is non-trivial to try and explain in a 5 minute YT video, but I do my best. I hope this helps!

Thanks to all of you space fans for watching this channel, it means a lot to me.

Hello there,

Please not to confuse that universe is expanding, it is same as it was, there are so many "Big Bang"happen to occure here and there in this universe and creating new galaxies, Stars, Comets Black Holes, Astoroids etc. We couldn't see them. Milkyway is expanding. After all the Universe is limitless,infinite full with energy- static&dynamic.

No other observable dimensions? Doesn't each speed have its own dimension? I.e. it's all 3D moving at different speeds so while you can call it all 4D, doesn't the 4th dimension alter reality according to the speed of the observer? A jet aircraft experiences all of Earth within a day's travel while a traveller in a surface vehicle must travel days or weeks. Photons of light are simultaneously at their point of emission and absorption though they are observed as moving at finite speed.

Different intelligent lifeforms throughout the universe will have different theories to how the universe works, with different sciences. They could be very similar to ours or way off. I think that intelligent lifeforms will have debates over which theories are correct, much like in the present where people argue about religion.

Not in mine. Religion is damaging to human progress.

Correction: Science is the search for fact.

[Alexander Dumais]

Religion is faith, Science is fact. That's not to say religion is inferior to scientific knowledge. They both have places in human experience.

[Mesdriver]

Science will never become a religion.

@NeverANiall Our science and our way of thinking, may very well one day, become our religions.
