Yeah, lol. When you're already in space electricity driven engines do work, like Ion thruster, but for breaking away from Earth's gravity we still need to figure out some new physics, not totally impossible.

I think in the future larger ships will be constructed outside of Earth's atmosphere. People will use smaller ones to transition to the surface, or maybe like space elevators.

I also think eventually we won't rely on combustion to reach the atmosphere. My thoughts were centrifugal force or some kind of magnetic accelerator.

That being said, I am in no way an expert. Just some dude on reddit.

I like the space elevator (easy on the Moon and even Mars) for Earth there's also laser launcher/accelerator, also doubles as wicked laser gun.

Aliens: So how did you get your ship so fast without warpsrive?

Humans: "oh we set off nukes behind ourselves and ride the explosion."

Aliens: "the fuck? How did you nit destroy your planet already?"

Humans: "oh no, we get to the explosion ships by shooting a smaller ship with lasers to send it to orbit, or we just hurl it through a giant rail gun into orbit.

Aliens: O_O

yeah, lol, and here's just the thing to launch humans from a giant rail gun (slightly tweaked Julius Verne original idea btw):

"A protein found in human cells has been repurposed to make a material that reforms when it is struck by a projectile, capturing the object intact"

"When something hits the gel, the energy unfolds the modified talin switches rather than being converted to heat, as is the case with existing materials, says Goult. Silica gels filled with air, or aerogels, have previously been used to capture small objects in space, but these heat up on impact, potentially damaging both themselves and the captured material."

Perfect airbag to cushion the 20 G's hitting your meatbag, lol
