Physicist Answers Physics Questions From Twitter | Tech Support | WIRED
Physicist Jeffrey Hazboun visits WIRED to answer the internet’s swirling questions about physics. How does one split an atom? Is light a wave or a particle…or both? How soon will the universe end? Is time travel is possible given physicists’ current understanding? What’s the deal with string theory? Director: Lisandro Perez-Rey Director of Photography: AJ…

There needs to be a correction to his answer as to when the heat death of the universe will occur. It is going to occur WAY WAY WAY WAY after 40-50 billion years. The last black hole with evaporate after a googol amount of years, which is 10^100 amount of years. Thats way more than 40-50 billion. Its more like going to happen in around thousand trillion trillion trillion trillion trillion trillion trillion trillion years. However, this is only if the assumption that proton decay is correct, and we have yet to observe it. If it isnt correct, and protons dont spontaneously decay away after a certain period of time, then black dwarfs – not black holes – will be the last thing to evaporate away. As previously stated, the last black hole will evaporate away in a googol amount of years, or 10^100. The last black dwarf however, wont evaporate away until 10^32,000.

The observable universe is finite. What is beyond the observable universe, as the name suggested, is not observable. We really know whether the universe is infinite or not.

I appreciate the effort of science communicators, but I have to say that oversimplifying their fields long-term will make more damage, than the short-term good of getting kids interested in doing something useful in their lives, rather than voting Trump, brexit and fighting for Putin.

This guy has a great way of explaining, but he gets some things wrong. The heat death of the universe for example will not happen in tens of billions of years, but much, much longer. Millions of trillions of years. Red dwarf stars for example should burn for a trillion years or more by our simulations.

The speed of light is really the speed of causality. It’s just that massless particles like photons (light) or electrons always move at the speed of causality, in a vacuum.

One thing I’d like to ask to Jeff : what if the universe never ends? Yes, I know, data shows that its curvature is unlikely negative, BUT! What if its topology is like a Möbius strip, or a torus, and singularities just lead to the other face of the universe, made of dark matter and dark energy, that we cannot detect because we’re on this side on the universe?
Ivan Alvarez
November 8, 2023 at 10:57 pm
I think the universe will die at the same time as it’s rebirth. Everything will be cold and distant and then come back towards itself at a center to create another big bang. Futurama got it right

I don’t know if the guy that Tweeted knew it and was making a joke, but special means something like “specific” in the sense of “restricted to a certain subset. It doesn’t mean special in the most common use of the word we do today.
In many languages it is translated as something like “restricted relativity”, and after that came General Relativity, of which special relativity is a subset under specific conditions.

The heat death of the Universe will happen in approx. 1.7 trillion trillion trillion trillion trillion trillion trillion trillion years. but the stellar era that we live in will end so much sooner. In fact this is a brief time period in Universe’s history where there is light, the vast majority of it is in darkness where there is nothing but black holes for trillions and trillions of years.

Can someone explain please? So at 12:14 he says that the universe is infinite and the amount of time the universe will be around is infinite. Yet, a bit earlier he says that the heat death of the universe will occur in 50 bln years. So is it infinite or not?
Anon Ymes
November 12, 2023 at 3:34 pm
The universe will still _exist_ after its “heat death”, it’ll just be “dead” (all stars will have died and the entire universe will be in thermodynamic equilibrium, meaning life is impossible). It’s a bit like a glowing ember – when it stops glowing there’s still _something_ there, there’s just no glow and no heat. And it’s estimated to be _way_ further in the future than 50 billion years (he just misspoke there – current estimates put it at 100 _trillion_ years or more).
(to be clear BTW, we don’t actually _know_ that’s how the universe will end – it’s one possibility but whether it’s actually true depends on the average density of matter in the universe and how accurate our cosmological models are)

Some of the questions these people answer are proof to me that the American education system is fine.
