Michio Kaku: What's the Fate of the Universe? It's in the Dark Matter

Why should you bother to wake up tomorrow knowing that we're all going to die billions and billions of years from now when the universe turns to absolute zero, when the stars blink out, when we have nothing but neutron stars and black holes? Dr. Kaku says that billions of years from now we may be able to move to a different universe.

Transcript -- In cosmology we believe that the universe started off in a big bang 13.7 billion years ago. All alternatives have been pretty much ruled out. Steady state theories, other alternatives have been ruled out. However, how will the universe end? We have several possibilities. One possibility is a big crunch when the universe squashes together in a gigantic ball of flame and maybe bangs once again. Another possibility is the big freeze, that the universe expands and just keeps on going and we're all going to freeze to death and we're all going to die when the universe reaches near absolute zero. Then there is something called the big rip where the universe goes into an exponential expansion and expands so rapidly that the distant galaxies can no longer be seen because they travel faster than the speed of light, that even the distant galaxies break the light barrier, and that's called the big rip, meaning that the night sky will be totally black except for some of the nearby stars.

Which of the three alternatives is the fate of the universe? Well, the short answer is we don't know. However, what we do know is that the universe is undergoing an exponential runaway expansion. The universe at the present time is careening out of control. Every astronomy textbook says that there was a big bang. The universe is expanding, but it's slowing down. It also says that the universe is mainly made out of atoms. Every textbook says that. The universe is made out of atoms. The universe is expanding, but slowing down. Both are wrong. We have to rewrite every single high school textbook on the planet earth. The universe is not mainly made out of atoms.

Four percent of the universe is made out of atoms, just four percent. 23% is made out of dark matter. 73%, which makes up most of the universe, is dark energy, and unfortunately, we are clueless as to what dark energy is and what dark matter is. In fact, if you ever find out what dark energy and dark matter is, be sure to tell me first.

Now why is that important? Because the amount of matter and energy in the universe determines the rate of expansion. We now know there is a lot more dark energy than we previously thought. Therefore, the universe is undergoing an inflationary exponential expansion. It is in a runaway mode, but here is the catch: we don't know how long that runaway mode is going to last. Some people say that it's temporary. We're in this huge expansion right now, exponential expansion, but it's going to reverse itself. Instead of a red shift, we'll have a blue shift as the universe collapses. At the present time we simply don't know. Why don't we know? Because we don't know what dark energy is. In fact, if you were to try to write down a theory of dark energy, your number would not correspond to the data by a mismatch of 10 to the 120. That is the largest mismatch in the history of science. There is no mismatch bigger than 10 to the 120. So this is a mystery. Until we solve the mystery of dark energy, we do not know the ultimate fate of the universe.

My personal thoughts are that perhaps we will continue with this exponential expansion and perhaps go into a big rip mode and at that point all intelligent life in the universe will die. All the tears and all the struggles and all the heartbreak of humanity since we rose from the swamp, it's all for nothing. Why should you bother to wake up tomorrow knowing that we're all going to die billions and billions of years from now when the universe turns to absolute zero, when the stars blink out, when we have nothing but neutron stars and black holes? What does it all mean anyway, if we're all going to die in a big rip?

Well, my personal attitude is that when the universe is about to die, why not leave the universe? Trillions of years from now, we will have the ability to bend space and time into a pretzel. We'll be able to tie space into knots. We'll be what is called a type three, maybe a type four civilization, a galactic civilization with the capability of harnessing galactic power. At that point, when the universe becomes so cold that all life is freezing to death, I say let us escape the universe, go into hyperspace and go to another universe.

Although I'm too far from being an expert, I can suppose dark matter and energy refer to something detectable to a certain extent by our current equipments that interferes with the known physical data in a way pretty similar to how particles and waves interfere with themselves. They're called dark because they can only be detected indirectly from the behavior of observable matter and energy. This is based on my interpretation of a lot of videos on physics and books such as Einstein for dummies.

[Michael Broschek]

Michio Kaku must love telling people that text books are wrong and giving us the percentages of what makes up the universe. I think I've heard the exact same thing in 10 of his videos now even if it's barely related to the video title :P

[frisa96]

Watch the documentary series "The Universe" season 02 episode 06 "Dark Matter", they describe it there.

[frisa96]

Did you even listen to what he said? Only four percent of the universe is made up of normal matter. Duuh...

[frisa96]

He IS a genius, after all, smarter than our textbooks. It would be inhuman of him not to boast about it :o

[frisa96]

Dark Energy was detected through this: If you first take a look at a star, you see two forces fighting each other, one being gravity, which wants to collapse the star, I don't know what the other is called, however, it comes from Energy, which wants to expand the star.

So, if energy wants to expand the star, wouldn't it want to expand everything else? There is an invisible force, that makes the galaxies move from each other, and the only logical explenation is energy which cannot be seen.

[frisa96]

That is correct. I once saw a documentary on Dark Matter and Energy. I'll tell you how they described it there.

Dark Matter can not be seen. You can't see it with the naked eye, nor with a telescope. However, what can be seen, is how light reacts to it. We all know that matter can bend light. So, basicly, if you see light being bent by nothing, the only logical explenation is some sort of matter which can not be seen. (Dark Energy in the next post)

[Farakhification]

I need take control of life !

[erack117]

Most of the universe isn't matter.

[TheChaosWarior]

You do not know what dark energy and dark matter is. You do know that 73 percent is dark energy and 20 or so percent is dark matter. How do you kow these percentages? I suppose you do have your reasens. Maybe a video on this?

[pat eastvalley]

Hahahahahaahhaaahahaa yeeeah and this professor dumbass really believes the universe is a result of evolution, not design.. Not even nature is designed if you ask this dumbass, while humans still learn to design by watchin natures designs.. I rest my case.

[monkerud2108]

so the universe is like a rubber band getting longer and thiner until it snaps :P
