Why can't we travel at the speed of light? How could mass reach infinity, when infinity isn't actually a number?

>How could mass reach infinity
It can't. Everytime we say something diverges to infinity in physics, we mean that we don't know what actually happens but it isn't good.
>>7890714
It can't.
The point is that the faster a massy object travels, the more energy it takes to accelerate it. This energy grows exponentially the nearer you are to c. Taking the limit, then, we say infinite energy (part of which will transfer as mass as well) is required to reach c with a massy object.

Gravity has the same speed as light, so the only logical and theoretical way to travel near the speed of light is to ride on a gravitational wave

I've read enough hentai to know where this is going.
>>7890714
mass doesnt increase, its invariant under lorentz transformations
>>7890714
>How could mass reach infinity
What you are referring to as mass is, in fact, energy, or in non-natural units, energy divided by [math]c^2[/math].
>Why can't we travel at the speed of light?
Because Kinetic Energy = Velocity * Velocity = n1, n1 * Mass = n2, n2 * 0.5 = n3 = Kinetic Energy.
As well, Energy = Mass * 299,741,000 = n1, n1 * n1 = n2 = Energy. E=mc2 is the KE in the first equation. That is, first calculate your KE, then plug KE into E in E=mc2, and you can calculate the extra mass you gain at that speed which = n1(Mass.) Then, take n1 and calculate the energy required to get that mass to your desired Velocity.
You'll note that the energy required to get anything to c is huge. Once you start using E=mc2, you'll note that your mass goes up as you near c. You quickly hit a brick wall where nothing you can do can get the energy required to reach that speed.
This is the physical limit that people say prevents FTL travel - all the other rhetoric saying it's impossible is a philosophy to protect the west's notions of causality.
However, curved momentum space suggests that as you gain E, the direction in which you're travelling (Called a vector) contracts from the force. So as you go faster, your mass increases and pushes against the space in front, and pulls the space behind you. So, the space in front shortens, and the space behind you elongates.

>[math]\frac12 mv^2[/math] doesn't hold at relativistic speeds, also see
Hence my explaination of how E=mc2 needs to be used to calculate the increasing mass. Or did you not read my post?
>>7890872
[math]E = mc^2 [/math] is only true for non-moving object. The general equation is:
[math]E=m^2 c^4 + p^2 c^2 [/math]

I thought gwaves are just a spacetime distortion? how to 'ride' that?
>>7890714
>>7890880
>E=m2c4+p2c
I assume you mean E^2.
Another way to view this is E= Mc^2, where M is the relativistic mass not rest mass.
M = m(1-v^2/c^2)^(-1/2); m = rest mass.

You have just answered your fucking question. You can't reach infinite energy, therefore you can't reach speed of light. Unless you are a massless particle, that is.
>>7890714
Whatever created the laws of physics certainly didnt want Type 0 civilizations the ability to easily make interstellar travel but search for more unorthodox methods instead.

>I thought gwaves are just a spacetime distortion? how to 'ride' that?
You can't. Space time engineering isn't a thing and the gravitational waves are not affected by the presence of matter or other gravitational waves.
>>7890714
>mass reach infinity
It would if it could but it can't so it won't
If you want to travel at lightspeed through space, you can't have mass.
And if you want to have mass, you can't be travelling at lightspeed.
Invent a space vehicle that has no mass; that's the first step to lightspeed travel.
Alternatively, find a way to travel through space without "moving". Build an Alcubierre Drive.

I cannot explain this fact to you in terms of something that you're more familiar with, because I do not understand it in terms of something that you're more familiar with. This is one of the elements of the world which you will have to accept on the basis of evidence, and from that and other similar facts, I can explain a great many things that look like they're unrelated.

> How could mass reach infinity
It doesn't. You never reach that fast in finite time.
> when infinity isn't actually a number
In some number systems, infinity is a number. It's not a Real Number, but there are other number systems.
>>7890714
Brainlet STEMtards use the term 'infinity' to describe things that their puny STEMtard brains can't compute
>>7890714
the mass actually approaches infinity never actually reaching it as you need more and more energy to go faster
>>7892943
I think I've seen god.
>>7892382
Why can't massless things go faster than light?
>>7892943
wat
>>7893853
E=mc^2
I don't think that things that hold literally no energy exist
>>7890880
Why write out such a long equation when you can literally simplify it to [math]E^2[/math]?
>>7890744
hence the alcubbierre drive, though most are skeptical about it

You partially answered your first question with the subject matter of the second
