Brian Cox Explains The Notion of Absolute Space

Brian Cox Explains The Notion of Absolute Space

#science #shorts #space

[d.e.]

It's quite simple really. I am the center of the universe.

[piyushsingh]

Actually Aristotle was not wrong. We're the centre of the universe. But the catch is everything else also is. Because in an expanding universe everything is moving away from everything else.

[garyfairbairn]

It's quite easy to understand, if you get in a car and accelerate then you feel that change. Once you're at the speed limit and travelling along you don't feel as though you're travelling. With being born on an already moving object it's like being born already travelling at the speed limit and you won't feel any of the acceleration up to that speed.

[costamavrodis]

Possibly the first to propose a spherical Earth based on actual physical evidence was Aristotle (384-322 B.C.), who listed several arguments for a spherical Earth: ships disappear hull first when they sail over the horizon, Earth casts a round shadow on the moon during a lunar eclipse, and different constellations are visible at different latitudes.

[Randall]

Not ALL of the Greeks thought this. Aristotle was far from their best scientific mind. Aristarchus, who lived long before Aristotle, knew that the earth revolved around the sun.

[SwampBarbie]

Why can't there be more men like Brian Cox on this Earth we can't feel moving!! FML

[AvangionQ]

You don't feel motion, you feel acceleration. If your velocity is constant, it registers as zero from your perspective, unless if you can somehow notice the movement.

[nikepanasonic]

Aristarchus of Samos proposed the heliocentric system…

[Dick-Pump]

Respect to the Greeks for thinking about it and then embarking on endeavor science

[coffeenotcoffee]

We don't feel it if it continues moving as it is but if earth's rotation stopped in an instant we would definetly feel THAT (giant tsunamis, gigachad earthquakes and getting flung at the speed of sonic the hedgehog)

[TheGreenMeanMachine]

The greeks did not believe in a flat earth!

[mikerosopht]

He leaves out the part where they were correct, however. Every point can be considered the center of the universe, so we are just as much the center as any other place is.

[gsltbjoe]

Weve always been moving, how would we know that we dont feel it? Its just the only way you can feel because it is how it is.

[gavo]

The Equivalence principle, another beautiful revelation from this incredible mind!

[sheromanysooklal]

Our world and the people are very Special.

[mikkel]

Maybe lowest possible time dilation and so preferred _local_ rest frame is just rooted in a 4D rotation structure of the hypersphere surfacing our universe. And when neutrinos are found to be massless, we will know.

[harleyb-ham]

The fact space goes on forever is nowhere near as mind blowing as if we actually found an end to it. What would it be, and how far would the "end" go?? Space has no other option but to be eternal.

[tricycle]

Nothing has changed, the Greeks STILL think they’re the centre of the Universe!

[imaginaryuniverse]

Our experience is how we imagine it to be.

[shadeus]

It's really not complex... We can't feel moving. We do feel accelerations and decelerations.
