- In this video I show you what happens when galaxies collide. I also show you what would happen if you were to shoot a rocket straight into space without turning. Would it ever hit anything? I show you how empty space actually is!
Software used was Universe Sandbox and SpaceEngine

If you shoot for the stars, you’ll always miss...literally
Hit or miss, i guess we'll always miss huh >:V
@@ironmaiden5658 Your argument is flawed. In the sand bucket situation, there is a much higher concentration of sand in the air compared to planets on a galactic scale. Meteorites hitting our earth are relatively small objects that were just drifting around and got pulled in by earth's gravity. In the situation in this video, planets wouldnt be affected by other planets' gravity considering the speed they're traveling at. They would just fly right past
which software is used?

THIRD COMMENT
it's hard for the human brain to comprehend the sizes and distances involved in this.
@Angel천사 no actually gravity is moving at speed of light.
TheGreg6466 Me: *Impossible*
Angel천사 Its literally impossible, logic and science proven to comprehend such distances.
I'll just like imagine im an ant and that large space he said is like the whole town
It's THAT big
so stop using it AND THINK WITH YOU RE REAL SELF
The scale of space is somewhat comforting and terrifying all at once. Think too hard about the nothingness and beyond and you get a feeling of dread, but look at at and you feel safe.
It’s so difficult to imagine that there are thousands of thing happening 100 million light years from us but light doesn’t even go fast enough for us to see it. Blows my mind the vast loneliness of space. Us humans are entirely alone
It use to frickin hurt my mind when I use to think about it in my childhood
'So this is going to be playing at about 1 million years per second. 3 2 1...Go'
And with the click of the mouse, all of us died nearly instantly.
No hell we did not! We did not die!
yeah, but I mean... we were already dead. That simulation started about 4 billon years ahead
@@ineonfox9245 God damn it! We are alive and kicking right here right now. Stop saying we are dead! Wtf is wrong with you people!
And also, we will never die. We will die in this form. But we will be reborn in some other form again and again. We will never really die!
@@fundemort okaay, I'm not saying we are dead rn. I'm saying we are dead in that particular simulation
@@fundemort certanly atoms of your body will be used in another things but does it make you feel better?
If a galaxy hit us, we should slap back.
Thats a much larger galaxy and
You should respect elders so just dont do that!
@@m.usmansohail2853 it just fat
DUH
yeah
If a galaxy hit us, we'd be sleeping like a baby
It would miss us completely.
Soo much empty space but we still don't have enough space to leave the trash somewhere
LoL u r right
so much empty space yet homes cost 1 million dollars each
Universe Sandbox is an amazingly dazzling universe simulator. This simulator is updated approximately every month. It's so amazing.
I agree it’s so cool
How did he got that map? And how could he be that fast?
I cant, i just cant find any map like that, i think im doing something wrong!
@@johnnick6878 check the description, the thing he uses to crash galaxies is universe sandbox and the thing he uses to travel and try to hit stars is called SpaceEngine

@@sagarmohanty1414 .......
The emptiness and the size of the universe just boggles my brain.
If it doesnt then you're doing it wrong
It's mind bottling
The real question here is: What are the odds that you shoot something in space and you hit an atom from a star?
That's my brother's luck.
Welll the real queation is: what are the odds that you suoot somewhere in space and you hit an nucleus of an atom of a stat!? 🤔
Any atom from any star? Almost 100%
You probably are already Made out of an atom of a dead star
"So I'm going 13 times the speed of light"
*Einstein* Am I a joke to you?
Well, yes but no. Einstein's theory of relativity is disproven by the simple fact that we cannot measure the true speed of light. A smart theorist for his time, but still a joke today.
It is theoretically possible to close distance of a light year but get older only by few days. If you measure speed as distance divided by the time that passed on your clock that you took with you, there is speed limits.
@@CubeGodd It didn’t disproved it.
The speed of light is a constant necessary for Maxwell’s law of electromagnetism to work out.
And Maxwell’s equations proved speed of light must be the same for all observers.
This video made me feel so small ... and a bit useless 😭
Just to make you feel a little bit worse, just imagine ALL that must be happening in this very moment across the whole universe. Imagine all the landscapes that we will never see. Imagine all the planets that are being hit by other bodies and exploding without even be discovered (by us). Imagine all the lifeforms that are being extinct by some astronomical event somewhere on the other side of the galaxy... And yet, us, humans, are arrogant enough to build walls because our skin is a little bit different from those other humans...

But still you will not be allowed to leave Matrix 6617
You can see Andromeda with the naked eye. Why would anyone question this? Maybe just not in a very densely populated city due to light pollution.
@@ProjectPhysX most probably but it's size in the sky will not be comparable to moon (as said by those sources ) in even next hundred year
I took a photo of Andromeda yesterday. Not very special one tho, since I was using quite wide angle lens.
A lot of your other videos and experiments are among my favorite videos on the internet, but this video has got to be one of your coolest and most mindblowing. I love relearning and finding higher appreciation for the incredible scope of this world we live in
*HIT OR MISS I GUESS YOU NEVER MISS,HUH?*
Universe: *hold my beer*
This is my favourite action lab video for now.I never thought about it.great stuff
One thing alywas confuses me. I read that things (suns and planets) we "see" out there were actually in the past positions. We see something because the light from that point comes into our eyes. So if we "see" a sun that is a million light years away. It means that that sun was there a million years ago. It's most likely not there anymore "right now". Action Lab please explain this.
That is true, you see things where they were and when they were when the light came out. So when astronomers say they just saw 2 black holes collide, that collision actually happened millions of years ago. But they did just saw it because the speed of light or gravitational waves are that slow.
That is quite a spectacular light show 😀
Star light show 👁
Yusss @-@
Damn, that gave me a sleepless night to think about.
this episode: "Everything is mostly empty space. we all live in world that ist mostly empty"
next episode: "how to cure depression"
with this type of science you need way more subscribers because this is insane
Problem is that most people are more interested in their next TicTok video than any kind of science.
10:22 'So at this point, this is going to look like warp speed'
If that's warp speed, how fast is LUDICROUS Speed?

Let us hope the inertial dampeners were not offline. That kind of acceleration would really hurt. Destination: nowhere.
Was thinking we were gonna see a gun being shot in space for some reason.
You should talk about particles and anti particles
I love how you also use Universe Sandbox 2 and Space engine. Thank you so much Action Lab, your videos are loved by my family and friends.
This was beautiful. Love this❤️
I didn't expect to enjoy this episode this much. I suddenly want to play some space game in which I can just take journeys through the cosmos:3
I recommend Eve Online. Be careful though. It can be extremely addicting if you take the time to get past the learning curve. The complexity is astounding yet incredibly rewarding.
I believe inside every single atom is another universe filled with it's own galaxies, stars, planets and life. Essentially no matter how big or small you get you'll always end up in another universe
POV: we a poop atom
I love your shows man everytime I watch my mind is blown good job keep up the great work

Thank you for my daily dose of making me feel insignificant
“So we’re going 63,000 light years per second, let’s speed it up a little”

It's blind blowing incomprehensible. Feels like seeing something we shouldn't have
Wow that was the most incredible video I've ever seen thank you so very very much. I learned a lot but most of it I knew already.
Thank you I love the vids!!!
I want that game or software on which he explains so well!!
Like after listening about how infinite our universe is.. My daily problems like ego, homework and others seem like senseless 🤯😂
It’s called Universe Sandbox 2 or you can use Space Engine.
Please make a video on 4D world
Btw keep up the good work

He action lab...can u please tell me the name of this software that u r using to view in space ??
Yeah
I think it is universe sandbox
it's *space engine* dude available on steam
It's in the the description
But it may hit because of gravity.
It is rare but not impossible
I've been into science for 2 years now but this video just shocked me!
Especially everything you said at the end!
Thanks for this! I love the similarities and differences of the universe and the atoms. How they coalesce to make bacteria, to humans, to planets, to suns, to galaxies, and to the universe. The space between each and every entity is so massive, in reference to itself, that it’s highly unlikely to even touch. But gravity gives us the attractive force to coalesce in the first place.
What is the name of software used for the demonstration
space engine for the rock throw, great software. Works in VR for a couple of weeks now.
Universe sandbox 1/2
Which software is this ?...definitely need this😍
It is the universe sandbox 2.
Thank me later
Space engine
• 2:58 - Yes, but as they get closer, the force of gravity increases and pulls on them harder. Plus, there are a large number of stars and planets in the galaxies, so it's likely that at least one or two stars or planets or asteroids will hit something or other.
• 8:33 - Because it's a simulation. In reality, the star would pull you towards it (it would work better if you weighed more).
• 12:15 - You'd likely be floating slowly, which would allow gravity to pull you in since you wouldn't zip past them.
• 13:24 - Deep Thoughts by Action Handy.
• If the universe is infinite, it is possible to hit something, you just have to wait long enough and go far enough.
8.33 I think the thing we are moving with its a small theoretical spaceship or something, it weighs nothing in galactic scales, you could just travel with it like he showed and the gravity of the stars won't change your way.
12.15 If you are floating slowly, then nothing will pull you in for billions of years. Or, it will, but you won't arrive.
13.24 The universe is most likely not infinite, but whatever, we couldn't comprehend it's size, so it is for us.
Great video showing how great universe sandbox really is. Love the software great for education

@@kevinrivas8860 its called Universe Sandbox 2
I love your videos and science keep it up!!!! 😘
This is something I’ve known for years, but it always makes me feel sad and alone. Sometimes I wake up at night and for a moment I’m able to comprehend just how small and insignificant we are and it terrifies me.
Now the real question is, would life on Earth be effected or would we just see a bunch of stars shooting by?
I think the stars would move and literally only astromists or other ppl who researches the stars would notice, put in to the world and become the new hot topic
Also, a bunch if ppl will think it's the end of the world
And the tides and seasons may change
And zodiac signs may never be proven once more
@@GHOUSTTM Tides or seasons wouldn't change at all. Like you first commented. Only astronomers would notice anything. Other than the faint glow of Andromeda getting slightly brighter, but most places on earth can't even see the milky way because of light pollution. Most constellations stars are not in the milky way or Andromeda, so the Zodiac signs wouldn't probably change either.
It's possible over millions of years that some orbits will shift. Probably not ours but it's not impossible. In any case our sun will have long since toasted our planet (or more likely humans will have moved the Earth and will have no problem dealing with anything Andromeda throws at us) so we really won't care. We will know several million years in advance of anything major.
We'll just send up Bruce Willis.
First we must survive the plague that affects humanity: humans... then we can worry about Andromeda

Amazing video, do more of space video🔥

The emptiness of space really puts into perspective for me the emptiness of my hole.
I'm here
I take my hat of sir, you just did an incredible closer for this video! Big respects to you. We cant even comprehend how big and how small the universe is how empty and at the same time full. Greetings from switzerland. And by the way if the macrocosm is so empty with the neutrinos and stuff but still it creates a human and etc. on the full picture maybe the universe is made similar and we just cant understand and comprehend because we are too small
During a galaxy merger, the question of stars hitting each other can be understood much more operational than just looking at the star itself, by instead seeing the star as a gravitational system, including planets and other orbiting things, like the Oort cloud. I'd say that stars affecting each others Oort clouds significantly constitutes a collision, leading to significant risk (chance?) of inner planets, like the Earth, being blasted by comets. If extinction becomes a real risk, it is a collision.
Your comment got me thinking, considering extinction risk first requires something that can go extinct. So another question could be: of all the stellar collisions (the kind you've described) during all the galactic collisions in the entire history of the visible universe, how many are expected to cause a full or partial extinction event (even if it's just bacteria)?
@@narfharder My general assumption is that risk of life forms going extinct is roughly proportional to the size, with protection from water and digging into ground also a factor. The low end of this scale means that microscopic life forms have a much lower extinction risk, unless in case of a much more severe sterilization event. Basically dinosaur-killer vs Earth/Thea collision. Risk of smaller events, like 65 MYA, is much higher than the ones making a planet one big volcano.
Of course, the major factor is what life forms the planet already have. Based on a sample of one (yeah, not much), to me it appears that simple microscopic life is not at all uncommon on suitable planets, but complex life slow to form, and blasted by repeated extinction events, is much more rare, and with the long time from complex life to a technological civilization, the latter is a very, very rare thing. Even more rare due to us having no reason whatsoever to assume that such life forms (like us) can be expected to have an endurance even getting close to the dinosaur era.
Basically, I'd expect it to be "normal" for galaxy mergers, even without outright major collisions, to be severely detrimental to life on quite a few planets, with many species going extinct. Due to the rarity of technological civilizations, such infestations would only be wiped out in a tiny part of galaxy mergers, as I'd still expect most stars (including the gravity system around the star) to not be severely affected.
Last sentence was cool !
Wonderful video.
If you at some point did a video on the exact software and how it works etc. that you use for these videos that would be great.
It looks very expensive, I don't even have a PC but I'm thinking of getting one for cool software like this.
The point you made about atoms though, I'm afraid is a very common misconception that I'd really like scientists to stop spreading. Atoms are not "empty space" at all in the common sense definition of empty.
Love your videos I never watch any other channels
Fascinating!
This was the best video yet
Actually, depending on how that program is done, since the distance step (your velocity times deltatime) is way higher than the size of the stars, you could be actually hitting them but the program just detects that your are appearing behind them after being on front.
But I'm pretty sure that the program might look for the stars that are between those steps. Just giving an idea that MAYBE you were to hit one but you went through it. Idk
12:15 it sounds like an inspirational quote but then ends with brutal reality.
Cool! I was about to pack my bags!
awesome simulation.
Love your projects 😅❤️
Seem like Han Solo just are paranoid when he jump to lightspeed 😂
Still a Rookie - Wookie
One of the first experiments to suggest the existence of atoms was firing alpha particles (which we now know are helium nuclei) at thin gold foil. Most of it would pass right through and every once in a while it would be strongly repeled. They concluded the gold had diffuse negative charge spread throughout (the electrons) with small points of positive charge to balance it out (the protons).
"Yet somehow in this empty space, we are here and exist"... Whoaow dude that's deep (13:25)
Tq fr the video dude
The high speed journey through the galaxy is a bit like scenes from Star Trek.
@The Action Lab
Can you tell us how to try this on our own using universe sandbox? Very cool!
Mind blowing!

nice conclusion
Love it
Thank you for triggering my existential crisis... Again..
Cool keep up the good work
consider also the LIGO observatories in Washington and Louisiana, measuring quantifiable compressions and waves in spacetime caused by gravimetric waves. What this means is that there's waves making all that empty space inside of us compress and stretch, if only minorly. I wonder what we might be able to do if we could actually influence such a power, what could we do with ourselves? With our world?
Considering it takes the energy of 2 black holes to collide and it changed spacetime by the 1/2 the width of a proton. I don't imagine we could do much with that. But human understanding is growing so who knows what the future will bring.
@@MrT------5743 1/1000th the width, but how small would the effect of a pebble be when diffused over a ring that's been expanding for billions of years? how much energy would it take to make a much smaller, localized distortion to spacetime? Hard to say. We do know the compression strength of space, so perhaps someone could find out the minimum energy required to make a measurable distortion in local spacetime... the trouble would be finding a way to detect that fluctuation in space without the instrument being affected by the shockwave in the air, I think. Sure it may not make a gravity wave on galactic scale, but to be able to control space to any degree terrestrially would be amazing.
Best science video ever.
Very intressting
